How it works

example method to use swap function

const Bioswap = require('bioswap-sdk')

const signer = // From PrivateKey or Phantom

const fromToken = "So11111111111111111111111111111111111111112";
const toToken = "BLLbAtSHFpgkSaUGmSQnjafnhebt8XPncaeYrpEgWoVk";
const amount = 1;
const rpcUrl = ""
const slippage = 3
const lookupTable = undefined

const bioswap = new Bioswap(rpcUrl, slippage,lookupTable, 1_000_000)
<!-- If you don't pass rpcUrl it will be default mainnet RPC url -->
<!-- If you don't pass slippage, it will be 3% automatically -->
<!-- If you don't pass fee, it will be 20_000 automatically -->
<!-- If you don't pass lookupTable, it will be undefined automatically -->

const init = async () => {
    const message = await bioswap.swap(wallet.pubkey, fromToken, toToken, amount);
    const transaction = new VersionedTransaction(message.message);
    const signedTxn = await signer.signTransaction(transaction);
    const tx = await connection.sendTransaction(signedTxn, {
      skipPreflight: true,
    });

    console.log(tx);
}
init()

example method to use getSwappedAmount function in Node.js with PrivateKey

const Bioswap = require('bioswap-sdk')

const signer = // From PrivateKey or Phantom

const fromToken = "So11111111111111111111111111111111111111112";
const toToken = "BLLbAtSHFpgkSaUGmSQnjafnhebt8XPncaeYrpEgWoVk";
const amount = 1;
const rpcUrl = ""
const slippage = 3

const bioswap = new Bioswap(rpcUrl, slippage)
<!-- If you don't pass rpcUrl it will be default mainnet RPC url -->
<!-- If you don't pass slippage, it will be 3% automatically -->

const init = async () => {
    const message = await bioswap.getSwappedAmount(wallet.pubkey, fromToken, toToken, amount);
    const transaction = new VersionedTransaction(message);
    const signedTxn = await signer.signTransaction(transaction);
    const tx = await connection.sendTransaction(signedTxn, {
      skipPreflight: true,
    });

    console.log(tx);
}
init()
