Smart Contract Structure

Types of contract:

• Factory Smart Contract

• Exchange Smart Contract

• Treasury Smart Contract

• Distribution Smart Contract

These contracts will be explained with detail later in the contract section of this book.

In this documentation, we introduce Fizzswap, the AMM protocol for the Silicon Network.

Fizzswap is a comprehensive DeFi protocol built on the Silicon chain, an Ethereum Layer 2 solution. As an Automated Market Maker (AMM) Decentralized Exchange (DEX), Fizzswap allows anyone to participate in the protocol and earn pool fees and various rewards.

Fizzswap supports the exchange of multiple tokens through optimal swap paths, a core feature of DEXs. Additionally, it offers a variety of services such as concentrated liquidity pool participation and token borrowing based on a single liquidity pool(supplying).

Beyond simple asset swaps, Fizzswap aims to lead the growth of the Fizzswap and Silicon ecosystems by providing users with new liquidity participation opportunities to access innovative and unique tokens quickly and freely.

Fizzswap has the following advantages.

1. Click [Manage] of the pool you wish to remove liquidity from on the V3 pool list page.

2. Click the [Remove] tab on the V3 pool detail page and drag the slider or click a button to select the amount (%) to remove.

3. When removeing from "You Get", click on [Remove] after checking the tokens and pool usage fee rewards that you will be receiving.

4. Click [Remove] once you have checked the estimated information on the "Confirm Transaction" pop-up. Click the [Confirm] button in your wallet once you have confirmed the information.

Providing Liquidity and LP Token

Users can deposit assets in any type of pools they favor, and we call these ecosystem participants Liquidity Providers (LP). Providing liquidity to the pool will result in the receipt of Liquidity Pool (LP) Token as evidence, and the number of LP Token received represents my share(%) in the entire pool.

If you remove all your assets from the pool, the LP Token will be automatically returned, and the user can receive the following rewards from the pool through the proof of LP Token during the asset supply period.

1) To remove assets, users must have LP NFT assets corresponding to the supply certificate in their wallets, and the NFT asset approval transaction must be completed. Transaction fees are incurred on the Klaytn chain when a transaction is executed. The wallet owner has the right to transfer LP NFT assets, so if the asset is transferred to another wallet, removal is not possible.

2) During the removal process, the difference between the price at the time of supply and removal may result in asset loss.

3) Due to balance changes at the time of removal, asset composition ratios and values are subject to change (see detailed policy on V3 Supply below), and all rewards (pool usage fee rewards, airdrop tokens, etc.) distributed up to that point will be automatically credited to user’s wallet.

4) Removals proceed only within the transaction range (slippage) set at the time of removal, and if the range is exceeded, the removal may not proceed. Proceed with removal after reviewing all related information in the estimated details section below.

What is a V3 Pool?

Unlike the V2 pool, which supplies assets in all price ranges (0~∞), the V3 Pool supplies assets in a specific price range. Concentrated liquidity refers to a supply of assets in a particular range, and liquidity can only be utilized within that range. Fizzswap's primary driving force is the expansion of liquidity pools. As more assets (liquidity) are supplied into liquidity pools, more transactions occur, and as more pool usage fees are distributed to liquidity providers, more liquidity and suppliers will join the Fizzswap ecosystem.

However, the existing V2 pool was built with a CPMM model (Uniswap V2) based on x ∗ y = k, which supplies assets in all price ranges. This leads to a problem of 'low liquidity efficiency', where most supplied liquidity is not utilized for trading. As a result, Fizzswap's overall trading volume and pool usage fee profit ends up declining, weakening the users' motivation to provide additional liquidity.

The V3 Pool provides liquidity at a price level where transactions frequently occur so that the created liquidity can be used for a broader range of transactions. Making a considerable fee profit will increase rewards for Fizzswap ecosystem participants to be carried out more efficiently.

Features of V3 Pool

The following are the key features of Fizzswap's V3 pool.

1) Distribution of pool usage fee to Liquidity Providers (LP)

V3 pool suppliers will receive 80% of the fee profit generated in the pool. The assets supplied in V3 pools are actively used for transactions, making it possible for suppliers to generate more profit.

By distributing these pool usage fee profits to suppliers, suppliers can reduce their chance of impermanent losses in liquidity supply.

2) Types of V3 pools

Users can customize the price range for supplies. Users can also supply quickly and conveniently by choosing one of the three price ranges (Spot, Wide, Full range) provided by Fizzswap V3 pool. Price ranges of each type range from +n% to -n%, according to a parameter previously set by a contract.

A ‘price range’ represents the range of prices within which supplied assets can be traded, and when a transaction is conducted within that range, suppliers will receive their pool usage fees. Each price range has the following characteristics.

Characteristics of Spot, Wide, and Full price ranges

Suppliers can expect a higher pool usage fee profit if the price range is narrower, as the liquidity provided by users are more likely to be used for transactions.

However, since tokens with large price fluctuations are supplied intensively in a narrow price range, it is necessary to continuously monitor the current token price to ensure that it stays within the supplied range. In such a case, the assets should be migrated to valid price ranges where the swap occurs. Furthermore, the more suppliers provide within a narrower price range, the more likely the token's price will change from the time of supply, causing the impermanent loss to increase(Please refer to.)

Using the above method, Fizzswap V3 pool offers suppliers with no previous experience in providing V3 liquidity the convenience and flexibility to do so. Future updates will enable suppliers to customize their price range.

3) V3 pool Migration(V3 → V3) Support

The Fizzswap V3 pool offers one-stop migration, allowing suppliers to migrate their assets with a single transaction. The detailed procedure consists of asset removal - supply in a new price range, and suppliers can migrate from the details page of the pool they provided liquidity for.

Fizzswap's Growth Through V3 Pool

V3 pool aims to make the flow of liquidity capital within the ecosystem more efficient and dynamic. V3 pools will offer a more favorable trading environment, thereby enabling Fizzswap to secure a higher trading volume.

Growth of Fizzswap Ecosystem

The V3 pool distributes 80% of the pool usage fee profit to V3 pool suppliers in order to continuously fill the pool with new liquidity. As a result of such a process, Fizzswap's TVL rises, creating a virtuous cycle, which ensures abundant liquidity, and generates more profit from pool usage fees based on that high TVL.

What is Crypto Wallet?

To use Fizzswap, you must first create your crypto wallet. In the DeFi protocol, a personal crypto wallet is your account. You can make transactions using cryptocurrency such as supplies, removals, and swaps by connecting your wallet to Fizzswap.

🐾 Step 1) What wallets work on Fizzswap?

Before you start using Fizzswap, you must set up a personal wallet. In the DeFi protocols, wallets serve as your primary financial accounts.

Fizzswap currently supports the following crypto wallets. (based on October 7th, 2024)

🐾 Step 2) Select a wallet

Refer to the guide below to select and create a crypto wallet you want to use.

⚠️ NEVER, in any situation, should you ever give someone your private key or recovery phrase ("seed phrase").

⚠️ The genuine Fizzswap site and staff will never ask you to input your seed phrase.

Token swaps are the simplest way to exchange various tokens circulated on the Silicon chain according to ratios of token pairs supplied in the pool.

Once users swap (trade) tokens through Fizzswap, the pool usage fees will be determined by the reward policy of each liquidity pool, and the pool usage fee will be distributed as follows.

• 80% of the pool usage fees incurred in all pools are distributed to liquidity providers in proportion to their respective LP shares.

• 20% of the pool usage fees incurred in all pools are distributed and accrued to the Governance.

1) Fizzswap's migration function usually goes through the following steps:

Approve (assets approval) - Remove the assets in the previous price range - Swap assets - Supply assets in a new price range.

2) To remove assets, users must have LP NFT assets corresponding to the supply certificate in their wallets, and the NFT asset approval transaction must be completed. Transaction fees (ETH) are incurred on the Silicon chain when a transaction is executed. The wallet owner has the right to transfer LP NFT assets, so if the asset is transferred to another wallet, removal is not possible.

3) During the removal process, the difference between the price at the time of supply and removal may result in asset loss.

4) Due to balance changes at the time of withdrawal, asset composition ratios and values are subject to change (see detailed V3 supply policy below), and all rewards (pool usage fee profits, airdrop tokens, etc.) distributed up to that point will be automatically credited to user's wallet.

5) For removed assets, the smart contract automatically swaps and supplies the assets at the optimal rate based on the pool exchange rate for the user's chosen price range. When a swap is required, the V2 and V3 pools are used as swap routes and transaction fees are incurred. Each pool has its transaction fee rate.

6) Supplies are made after swap fees are subtracted. When swapping, the larger the transaction size (quantity), the greater the effect on the exchange rate between tokens in the pool, resulting in a difference between the current price and the price applied at the time of the exchange (price impact). Multiple runs in small quantities can reduce the impact.

7) Depending on the transaction size, there may be a price difference (Price impact) at the time of exchange, so the expected exchange rate at the time of supply may not match the actual exchange rate. For this reason, supplies are only made within the transaction range (Slippage) set at the time of the swap, and if the range is exceeded, the supply transaction may be reverted (Revert). Proceed with the supply after checking all the information on estimated returns at the bottom.

8) Some assets may remain after supplying to the V3 pool, and the remainder will be automatically returned to the user's wallet.

This contract manages V3 pool airdrop operation. Operators with authority can set up and execute airdrops through V3Treasury contract. Airdrop is available only for token0 and token1.

① Drag the “minimum price bar” and the “maximum price bar”

Price Range Fall Out

A 'price range' refers to the minimum and maximum price ranges in which an asset can be traded, and suppliers will receive pool usage fees if a transaction occurs within the price range.

When the token price of the supplied pool fluctuates, the ratio of assets in the pool changes. And if the token price falls outside the range due to drastic changes in token prices, suppliers will only hold one token from the token pair. In that case, supplied assets cannot be traded within the rages, so pool usage fees and rewards cannot be earned.

This contract is Airdrop plan contract applied to the pool. You can target one liquidity pool and one token. The contract is executed by an operator with authority through Treasury.

Events, Read-Only Functions, and State-Changing Functions

AMM is an innovative trading mechanism that evolved from order book-based DEXs to change the way we trade cryptocurrencies on-chain. Instead of buy/sell order books, liquidity pools created by liquidity providers allow traders to trade freely, and liquidity providers share any generated pool usage fees as revenue in proportion to their individual liquidity contributions. In addition, any holder of Silicon Compatible Token can become a liquidity provider.

The AMM mechanism of Fizzswap is based on the formula x * y = k where x = ETH, y = Token1 , and k = Constant Function. The token price range is set according to the quantity of each token when the corresponding liquidity pool is created. For example, if the liquidity supply of x (ETH) increases, the supply of y (Token1) decreases to maintain the constant function, k. In this way, the supply of each token in the liquidity pool is designed to fluctuate with prices set accordingly.

Structures of Services:

Swap

Fizzswap provides a seamless way to exchange one token for another at a rate determined by the ratio of token pairs within the liquidity pool.

Additionally, Fizzswap offers a "single-asset supply" option in its liquidity pool (V2, V3) services. This feature allows users to supply liquidity to a pool using a single asset, even if they only hold one of the pair tokens. The platform will automatically swap the single asset to create the required pair and add it to the pool.

Supply & Borrow (Coming soon)

Fizzswap's Supply & Borrow service allows anyone to freely supply or borrow tokens. Users can maintain liquidity without swapping assets, while simultaneously borrowing desired assets for trading.

• Suppliers receive aToken and LP rewards when supplying a single token to the pool, and can leverage the supplied asset as collateral to borrow other tokens.

• Borrowers pay a borrowing fee (APY) to the liquidity pool in exchange for borrowing assets. A portion of the fees paid by borrowers is distributed to suppliers as LP rewards through a smart contract.

Providing Liquidity (V2, V3)

Fizzswap supports various way of providing liquidity.

When participating in V2 pools, users receive Liquidity Provider (LP) tokens representing their share of assets in the pool. V2 participants earn a portion of the pool usage fees generated in the pool and may receive additional rewards based on their LP share.

V3 pools offer concentrated liquidity, maximizing asset efficiency. Liquidity providers can specify a price range for their supplied assets, ensuring they're only used within that range. Through the Concentrated Liquidity Market Maker (CLMM) design, providers can allocate capital more efficiently, leading to higher pool usage fees earnings.

When supplying liquidity to V3 pools, users receive V3 LP NFTs as proof of their share. Similar to V2, V3 participants earn pool usage fees and may receive additional rewards based on their LP share.

*Note that slippage (a difference in the estimated price at the point of transaction and the actual price at time of transaction) may occur in AMM-based swap protocols. In addition, a liquidity provider may experience Impermanent Loss (change in price of supplied assets compared to when they are supplied) as token prices in pools are adjusted by an AMM mechanism after the point of supply.

Please keep these risks in mind when providing liquidity or conducting transactions.

This contract acts as an administrator to manage the voting registration, voting counting, and execution of the Fizzswap. It also performs important parameters of Fizzswap, proposal registration, and voting execution.

Providing Liquidity & V3 LP NFT Token

Liquidity Providers (LPs) are ecosystem participants who supply assets in V3 pools. Fizzswap manages price ranges of concentrated pool with NFT. Users will receive Fizzswap V3 LP NFTs as proof of providing liquidity when they supply assets into liquidity pools.

The NFT represents ownership of the assets supplied, so users will continue to receive pool usage fee profit from that pool while their assets remain supplied.

When assets are removed from concentrated pools, the corresponding NFTs are automatically returned as they no longer provide liquidity.

Please be aware that the use of Fizzswap has the following risk factors.

• Fizzswap is a blockchain decentralized protocol without a central entity. Users participate in transactions through liquidity pools on the blockchain created by other users at their own responsibility and judgment. This may lead to users being unable to receive recovery support from someone or Fizzswap for the results of an user's mistake, so it is always recommended to test with a small amount first to manage the risk caused by mistakes(mistransfers, etc.).

• All assets and asset liquidity pools identified on the Fizzswap website are tokens on the Silicon chain that are self-registered by users without going through individual screening, and their safety is not guaranteed by the Fizzswap team.

• Based on the nature of the AMM (Automated Market Maker) method, the asset price a user receives on Fizzswap can vary significantly depending on the swap size, the amount(ratio) of assets currently waiting in the pool(percentage), and the changes to pool's real-time supply and removal of liquidity.

• Asset price fluctuations may cause assets to be deposited or withdrawn from the pool at prices or ratios that users did not expect. Also, if there is a price change from the price at the time of depositing in the pool, you may incur a loss when withdrawing, compared to the case that you simply hold the asset.

• All Figures displayed on the website are estimated information provided to help users make decisions, and do not guarantee the timeliness, suitability or accuracy of the data.

• A normal Fizzswap website never asks for the user's personal wallet private key, mnemonic key, and seed phrase to be entered.

• For other risk factors, precautions, and conditions of use, please check the link below.

1. Abstract

Fizzswap is a decentralized application (DApp) based on Silicon Chain which is developed by a third party. Fizzswap is designed to provide users with an easy-to-use interface such as Fizzswap website(https://fswap.io) (Hereinafter Fizzswap and Fizzswap website are collectively referred to as the “Fizzswap”) to the decentralized protocol that integrates directly with Silicon blockchain wallet of a user, to swap various digital assets and to provide liquidity.

NOTICE: This guideline contains the terms and conditions by which you may access and use the Fizzswap. Please read this guideline carefully. By accessing or using the Fizzswap after you check this guideline, you signify that you have read, understand, and agree to be bound by the terms and conditions in its entirety.

2. Revision terms of this document

The contents of this document can be revised at any time for the purposesreasons such as change, addition, deletion, supplementation, user protection, and error correction of Fizzswap. If the content of this document is revised, the revision will take effect from the time the changed contents is posted. However, if the content to be changed is unfavorable to the user or is a significant change, it will be posted 30 days before the effective date. If the user checks the revised document after the effective date and continues to use Fizzswap, it is deemed that such user has read, understood and agreed to the revision.

3. Eligibility

• To use Fizzswap, an user must be at least the age of majority in civil terms in his/her country (ex: 21 years of age in Singapore). Also, a user must be able to make a statement that you have full rights and authority to enter into and comply with civil agreements on behalf of yourself or any legal entity that you represent.

• An user must be able to make a statement that a user is (i) not subject to any economic or trade sanctions by any governmental authority (including, but not limited to, the Office of Foreign Assets Control of the U.S. Department of the Treasury, etc.); (ii) is not citizens or residents of any jurisdiction subject to comprehensive economic sanctions by the United state, and will not use Fizzswaps for the purpose of illegal activity conduction, promotion, or designing.

4. Precautions when using Fizzswap

4.1. General Precautions

For reliable network/service while using Fizzswap, please read the following guideline carefully.

• It is recommended that you access the service with only one instance/tab.

• The service may be limited if you use multiple instances/tabs for prolonged period of time, using a public/shared IP access point and/or there is an excessive amount of connection requests.

• If you are having difficulty with connectivity for whatever reason, please close all instances/tabs and access the service after at least 1 hour before re-connecting.

4.2. Precautions regarding supplying/removing liquidity

4.2.1. Supply and Remove Liquidity

Users should be aware of the following when suppling and removing assets.

• To request a transaction, the user must have a Silicon wallet to hold Silicon-based assets, along with a minimum amount of Silicon (ETH) to use for transaction fees

• Liquidity on the Silicon chain is provided with Silicon-Compatible Tokens issued on the Silicon chain. Hence, an asset that is not a Silicon-compatible Token and based on other blockchains, including but not limited to Ethereum, Ripple, BSC, must be converted into a Silicon-compatible format through bridging protocol(e.g., Oribit Bridge) prior to being deposited into Fizzswap.

4.2.2. Asset mis-transfer

Users must accurately check the asset type and address when transferring assets between wallets. If a user transfers a type of asset that is not supported by Silicon Chain, or if the required transfer address is not entered or entered incorrectly, such transfer may not be properly processed and assets may be irreversibly lost.

Please refer to the link below for more information regarding mis-transfer of assets.

• Even for some assets (e.g., Ripple, XRP) that are heterogeneous chain’s assets from Silicon, which can be transferred between wallets directly through the Fizzswap interface without going through the bridge site, the user must accurately enter the transfer address and destination tag assigned to each wallet. If the transfer address or destination tag is not entered or entered incorrectly, such transfer may not be properly processed and assets may be irreversibly lost.

• Fizzswap is a decentralized application in which the private key of user assets is not managed by a central entity. Fizzswap has such structure in which asset recovery or/and technical support from a central entity are impossible for the consequences from users' mistake or negligence including but not limited to wrong transactions described above. This structure is designed so that if a user transfers an asset incorrectly, no one, including Fizzswap, can access the asset. Due to the decentralized nature like this, capabilities and responsibilities of Fizzswap team for mis-transfer may not be similar to the support of many centralized exchanges(e.g., Upbit, Bithumb, Coinone, ect.) for technical and structural reasons

• To prevent losing assets, we recommend that users test with a small amount of assets prior to sending a larger amount.

• For supply and mis-transfer occurring as a result of using Silicon Bridge, please refer to the respective site’s policies.

4.3. Providing Liquidity, Removing Liquidity, Swap

You can act as a Liquidity Provider by providing liquidity to a Liquidity Pool(e.g., Single pool, V2/V3 pool) in Fizzswap; however, you must carefully evaluate and consider the risk before proceeding with the transaction, and take responsibility for your own actions and judgments.

4.3.1. Price

Fizzswap works based on the AMM(Automated Market Maker) method. Price of each token within Fizzswap is determined by the liquidity pool ratio of tokens within the relevant Smart Contract. As automated Smart Contract makes adjustment to price as per the formula (x*y=k), the price shown on Fizzswap interface may not be the same as prices shown at other exchanges, and cannot be guaranteed for accurate or appropriate market prices.

• Each token price at the time a user supplies, removes, or swaps assets is determined by the above price measurement method (exchange ratio of token pairs), and the price is not directly proportional to the exchange quantity.

• In addition, as the exchange rate of token pairs momentarily changes due to the real-time participation of various participants, the price displayed on the Fizzswap website right before the transaction may change at the time of the transaction, and the price applied at the time of the actual transaction may vary. (e.g., Transactions occur in token pairs, asset supply and removal of token pairs, etc.)

• The Fizzswap Protocol has a stabilization measure so that the request can be executed only within a certain range of the exchange rate to be applied by the user in order to minimize the loss that may occur due to the large change in the current exchange rate, but you should precisely check and confirm the exchange rate applied to the time of transactions when proceeding liquidity supply, removal, and swaps.

4.3.2. Rewards and Utilized APR(APY)

All reward APRs displayed on Fizzswap's website, including the Liquidity Supply APR, FIZZ Distribution APR, Airdrop APR, Pool Fee APR for using the protocol, Staking APR, and Utilization APR for using a Single Liquidity (Supply), are estimates of the rewards distributed on an annualized basis, and are not guaranteed.

For more details regarding rates of returns displayed, Please refer to below link

• In particular, at 9 a.m. (KST) every day, the FIZZ APR of each liquidity pool is updated reflecting the FIZZ Mining rate aggregated from the user pool vote and the FIZZ buyback quantity per pool. At this time, the figure that indicates FIZZ distribution APR includes the quantity allocated to the vFIZZ Holder(5%), development team (5%), Treasury(5%), Partner(5%) and the rewards that users actually receive is the amount that the quantity allocated for the team is excluded.

• Fizzswap strives to provide accurate information in real time as much as possible, but the expected APR displayed in the screen may vary from the actual APR due to price fluctuations of distributed tokens, changes in liquidity pool size, and delays in transaction processes.

• For details on calculating the expected APR, please refer to the relevant documentation on the Fizzswap website.

4.4. Provision for Each Liquidity Providing Method

4.4.1 Provision of liquidity for Pair Pool

Users can earn returns from token supply distribution rewards, and token airdrop by supplying two types of assets (pairs) on Fizzswap.

There may be delays when supplying pair liquidity. You can find out more details in the link below.

In the event that the market price of an asset that a user supplies changes significantly from its price at the time of supply, the user is more likely to receive a lower reward than if the asset was not supplied, and even incur a mark-to-market loss. These losses, however, become permanent when a user withdraws their assets from the pool (due to this nature, we refer to these losses as impermanent losses, see the link below for more information), and if the price difference between the price of the user's assets in the self-supply state before the user withdraws user's assets and the price when the user supplied user's assets to the pool is restored, then the actual loss may be reduced. Moreover, users' overall rewards should be calculated taking into accoun pool usage fee rewards. For more information on impermanent losses, please refer to the links below.

5. Additional Notes on Fizzswap V3

5.1. Concentrated Liquidity

Fizzswap V3 (Version 3) has a Concentrated Liquidity function. This notice refers to the liquidity pool with centralized liquidity as the 'V3 pool' and to the liquidity pool with the previous features as the 'V2 pool'.

Due to its principle of operation, the V3 pool provides users with more freedom and choice for centralizing liquidity supply and designating a supply section and, therefore, may hold higher reward expectations and greater loss risks than the V2 pool.

The V3 pool liquidity providing risks compared to the V2 pool liquidity providing are as follows. The narrower the designated price range becomes, the higher the chance of (i) a rise in the risk of impermanent loss (IL; Impermanent Loss), (ii) a rise in the risk of changing the composition ratio and value of supplied assets (There is also the possibility that the ratio of the two assets is fixed at 100:0 at the time of removal), (iii) a rise in the likelihood of not being able to obtain supply rewards when the token's price departs from the user's specified range, (iv) a rise in the risk of loss due to price range migration (V3 to V3 migration) when the price is out of the price range. For more information, please refer to the link below.

Concentrated liquidity introduction, background and precautions (Link) V3 Pool Supply Details Policy (Link)

As the V3 pool liquidity providing has high structural complexity and is difficult to predict the risk of asset loss (particularly when the liquidity is provided in a narrow price range), it is not recommended for users with little experience in investing in virtual assets and the personality that cannot handle the possibility of loss. Users must carefully evaluate and consider the risks of concentrated liquidity before supplying and managing liquidity to liquidity pools.

6. Prohibited Acts

Users must comply with this guide's precautions and not engage in the following actions.

• Activities that harm or disrupt the sound trading order of Fizzswap

7. NO WARRANTIES AND LIMITATION OF LIABILITY

• Fizzswap is a web-app interface that allows users to use their Silicon blockchain wallet to communicate with a decentralized protocol to swap assets and to provide liquidity. This means Fizzswap wields no control over individual Liquidity Pools, or the trust of a swap. It is the user’s responsibility to carefully consider the benefits and risks related, by taking into consideration token price ratio at the moment of swap, and all the necessary information to evaluate such risks.

• Expected APR, token price, an example of reward calculation, and all other information provided by Fizzswap interface help users make informed decisions for using Fizzswap or decentralized financial transactions such as providing liquidity, removing liquidity, and swapping. The information provided here is not a suggestion or a hint to invest or trade. Fizzswap makes a reasonable effort to deliver accurate information but does not guarantee the timeliness or accuracy of the information.

• Fizzswap is not responsible for user loss of assets, and for generating less rewards than projected, resulting from the use of Fizzswap.

• Fizzswap does not guarantee the continuity of Fizzswap service, and of the functions within. Any service or functions provided within Fizzswap can be added or deleted permanently, and Fizzswap itself may be stopped or changed. (In the case of a permanent stoppage of Fizzswap service, users that may be affected will be given a reasonable period (30days or more) and notifications/guide.)

• Fizzswap does not guarantee the reliability of Silicon blockchain platform used by Fizzswap Protocol, as well as any other third party services.

• There is no responsibility or authority on the part of Fizzswap for the contract execution technology set by a third party. Token issuing individuals or foundations that own the wallet (Deployer) with the corresponding authority, may stop, change, or suspend the execution of the token contract, and such changes may affect and limit the ability to supply or remove assets from the liquidity pool (LP) within Fizzswap. Thus, the inability to remove assets due to the execution of a specific token contract authority is unrelated to the functionality provided by Fizzswap (supplying and removing assets from autonomously created pools). Since Fizzswap does not have independent control over the user's private cryptographic keys, it is not structurally possible for Fizzswap to arbitrarily access, control, or intervene in the assets held in the liquidity pool, such as sending them to a specific address, which requires the action of the token contract holder's wallet associated with the liquidity pool pair causing the issue.

• Developers, operators and governance participants of Fizzswap do not endorse, guarantee, or assume responsibility in any way for any and all part of Fizzswap to the fullest extent permitted by law.

• Due to the complexity of software code and the nature of technology, the perfect integrity of the code cannot be guaranteed. Smart Contract codes used in Fizzswap may be susceptible to vulnerabilities which cannot be prevented by due diligence in the industry, and risks of asset loss exist(e.g., hackings or flash loan exploits utilizing those vulnerabilities).

• There is a continuous effort to maintain the block sync between Fizzswap and Silicon network; however, Fizzswap interface may be stopped without prior notice due to problems in the network resulting from transaction congestion, computer system errors and software attacks and other factors, such as natural events. Fizzswap is not guaranteed to work at all times.

• In aforementioned situations and more, there may be errors in the values/information displayed on the interface, as well as stoppage of service connection. User requests for swap, deposit, withdrawal and other transactions may be delayed or fail.

• Fizzswap, OUR DEVELOPERS, EMPLOYEES, OFFICERS, OPERATORS, AFFILIATES, AND GOVERNANCE PARTICIPANTS(HEREINAFTER, REFERRED TO AS THE “WE” OR “US” IN THIS AND NEXT SUBSECTIONS), MAKE NO WARRANTIES, EXPRESS OR IMPLIED, GUARANTEES OR CONDITIONS WITH RESPECT TO YOUR USE OF Fizzswap. YOU UNDERSTAND THAT USE OF Fizzswap IS AT YOUR OWN RISK AND THAT WE PROVIDE Fizzswap ON AN "AS IS" BASIS AND "AS AVAILABLE." YOU BEAR THE ENTIRE RISK OF USING Fizzswap. YOU ACKNOWLEDGE THAT COMPUTER, SOFTWARE, TELECOMMUNICATIONS SYSTEMS, AND BLOCKCHAIN SYSTEM ARE NOT FAULT-FREE.

• YOU UNDERSTAND AND AGREE THAT WE SHALL NOT BE LIABLE TO YOU FOR: ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL CONSEQUENTIAL OR EXEMPLARY DAMAGES WHICH MAY BE INCURRED BY YOU, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY.. THIS SHALL INCLUDE, BUT NOT BE LIMITED TO, ANY LOSS OF PROFIT (WHETHER INCURRED DIRECTLY OR INDIRECTLY), ANY LOSS OF GOODWILL OR BUSINESS REPUTATION, ANY LOSS OF DATA SUFFERED, COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR OTHER INTANGIBLE LOSS. UNDER NO CIRCUMSTANCES SHALL WE BE LIABLE TO YOU FOR ANY CLAIMS, PROCEEDINGS, LIABILITIES, OBLIGATIONS, DAMAGES, LOSSES, OR COSTS IN THE AMOUNT EXCEEDING THE ABOUNT YOU PAID US IN EXCHANGE FOR ACCESS TO AND USE Fizzswap, OR USD$100.00, WHICHEVER IS GREATER. THIS LIMITATION OF LIABILITY SHALL APPLY TO THE FULLEST EXTENT PERMITTED BY LAW.

8. Protection of rights and cooperation with law enforcement agencies

In the following cases, the measures to user's access information (e.g., wallet address, access information, etc.) to the Fizzswap website may be taken as reasonably necessary, such as being provided to a regulatory authority or judicial authority.

• When there are reasonable grounds to believe that the relevant asset is involved in hacking, money laundering, or other criminal activity

• When requested by a regulatory or judicial authority based on the applicable laws and regulations

9. Dispute

Any dispute arising out of or in connection with these terms including any question regarding its existence, validity or termination and any dispute arising out of or in connection with users’ access or use of Fizzswap, shall be referred to and finally resolved by arbitration administered by the Singapore International Arbitration Centre (“SIAC”) in accordance with the Arbitration Rules of the Singapore International Arbitration Centre ("SIAC Rules") for the time being in force, which rules are deemed to be incorporated by reference in this clause. The seat of the arbitration shall be Seoul or Singapore. The Tribunal shall consist of one arbitrator. The language of the arbitration shall be English.

V3 Supply Policy

1) Users can supply assets directly by entering the pool's exchange rate (price) that corresponds with the price range they are currently supplying.

2) Users can supply when they have two assets or even just one. In the case of two asset supplies, no swap occurs, but in the case of a single asset supply (A or B), the smart contract swaps and supplies assets at the optimal ratio based on the current pool exchange rate. If a swap is required, V2 and V3 pools are used as swap paths and transaction fees apply. Fees are based on the pool's transaction fee rate.

3) Supplies are made after swap fees are subtracted. When swapping, the larger the transaction size (quantity), the greater the effect on the exchange rate between tokens in the pool, resulting in a difference between the current price and the price applied at the time of the exchange (price impact). Multiple runs in small quantities can reduce the impact.

This is a V2 Pool smart contract to expand ERC20 that is created with every liquidity pair. The Factory deploys this as new pool creation is requested. Although the Factory actually stores the two tokens of a pair and swapping takes place through it, the Exchange Contract must be called for liquidity to be provided or taken.
