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 list token in flowx and their's metadata.
• Retrieve user liquidity.
• Retrieve list farm genesix and user position.
• Retrieve list farm FaaS and user position.
• Retrieve transaction block for swap V2
• Retrieve transaction block for swap V3
• Retrieve transaction block liquidity management V3 (add,remove,increase liquid, collect reward)

Getting Started

2. Retrieve list farm genesix and user position

import {getGenesisFarm} from "@flowx-pkg/ts-sdk"

let address: string = "..." //optional: user address
let listGenesisX: IGenesisPoolsData[] = await getGenesisFarm(address)

3. Retrieve list farm FaaS v2 and user position

import {getFaasV2} from "@flowx-pkg/ts-sdk"

let address: string = "..." //optional: user address
let listFaaS: IFaasV2[] = await getFaasV2(address)

4. SWAP V2 Function

import {calculateAmountIn, swapExactInput} from "@flowx-pkg/ts-sdk"

const coinIn = {
	type: "0x2::sui::SUI",

	symbol: "wUSDC",
	decimals: 6,
};

const data = await calculateAmountIn(0.8, coinIn, coinOut); //0.8 mean the amount you want to swap

const tx: TransactionBock = await swapExactInput(
	false, //it should be false for now
	data.amountIn, //amount want to swap
	data.amountOut, //amount want to receive
	data.trades, //trades from calculate amount

amountOut	Amount out by decimal value. In case build Tx for inspect transaction: This amount is equivalent to amountOut get from getSmartRouting. In case build Tx for actual transaction: This amount is equivalent to amountOut get from estimateGasFee	string
coinInType	Type of token in	string
account	Address conducting swap transaction	string
pathsAmountOut	(Optional) List amount actual calculated after estimateGasFee. Add this argument may turn txBuild to tx for actual transaction. Pass it may turn txBuild to tx for devInpsecTransaction	string[]

Usage Swap V3

import {txBuild, estimateGasFee, getSmartRouting} from "@flowx-pkg/ts-sdk"
