@flowx-finance/sdk

Official FlowX Finance TypeScript SDK for Sui

An FlowX Typescript SDK is a software development kit that allows developers to interact with FlowX protocols using the Typescript programming language.

Features

• Retrieve coin
• Retrieve transaction block liquidity management V2 (add,remove)
• Retrieve transaction block for swap aggregator

Getting Started

npm i @flowx-finance/sdk

Retrieve coin

Get instance of Coin[]

const coins = await coinProvider.getCoins({
  coinTypes: ['0x2::sui::SUI'],
});

Swap Aggregator

Get Swap Route

To find best route for swap

const quoter = new AggregatorQuoter('mainnet');
const params: AggregatorQuoterQueryParams = {
  tokenIn: '0x2::sui::SUI',
  tokenOut: '0x5d4b302506645c37ff133b98c4b50a5ae14841659738d6d733d59d0d217a93bf::coin::COIN',
  amountIn: '1000000000',
  includeSources: null, //optional
  excludeSources: null, //optional
  commission: null, //optional, and will be explain later
};

const routes = await quoter.getRoutes(params);

Use function getRoutes in instance AggregatorQuoter with it's arguments to create a Route

Arguments	Description	Type	Example
tokenIn	Token to be swapped from	string	'0x2::sui::SUI'
tokenOut	Token to be received	string	'0x5d....f::coin::COIN'
amountIn	Amount of tokenIn to be swapped	string	'1000000000'
includeSources	Optional: Sources to include in aggregation	null | Protocol[]	null
excludeSources	Optional: Sources to exclude in aggregation	null | Protocol[]	null
commission	Optional: Commission amount for the transaction, use when you want calculate commission with partner fee	null | Commission	null

Build Transaction for aggregator swap

Build transaction that you can use with SuiClient or Dapp-kit

const tradeBuilder = new TradeBuilder(NETWORK.MAINNET, routes); //routes get from quoter
const trade = tradeBuilder
  .sender('0xSenderAddress') //Optional if you want pass coin later
  .amountIn('1000000000')
  .amountOut('500000000000000000') // Estimate amount out, usual get from quoter
  .slippage((1 / 100) * 1e6) // Slippage 1%
  .deadline(Date.now() + 3600) // 1 hour from now
  .commission(null) // Commission will be explain later
  .build();
console.log(trade); // Output: Trade object with configured parameters
const txb = trade.swap({ client }) // You can also pass coinIn and exist TractionBlock if you want

Find route and build transaction with commission

The Commission class represents a commission configuration for transactions, defining the partner, commission type, and value. It includes methods for computing the commission amount based on the specified type.

const commission = new Commission('0xPartnerAddress', new Coin('0x2::sui:SUI'), CommissionType.PERCENTAGE, '500', true);

if CommissionType.PERCENTAGE then value should be input 1/100 * 1e6 it is example of 1% if CommissionType.FLAT then value should be the amount of token you want to fee include decimals Then you should pass commission variable to both tradeBuilder and getRoutes for exact values
