import { swap } from '@cryptoscan/swap-sdk';

const secretKeyStr = 'YOUR_SECRET_KEY';
const wallet = getWallet(secretKeyStr);
const from = 'sol';
const to = 'HJAoYbnsf16Z8ftk3SsuShKLQQgzmxAPu41RTpjjpump';
const amount = 0.05;

swap({
  wallet,
  from,
  to,
  amount,
})
.then((tx) => console.log(tx))

Primary Usage

import { Keypair, Connection } from "@solana/web3.js";
import sendTransaction from '@cryptoscan/solana-send-transaction';
import { createTransaction } from '@cryptoscan/swap-sdk';

const rpcUrl = 'https://api.mainnet-beta.solana.com';
const wsRpcUrl = 'wss://api.mainnet-beta.solana.com';
const secretKeyStr = 'YOUR_SECRET_KEY';
const wallet = Keypair.fromSecretKey(bs58.decode(secretKeyStr));
const from = 'sol';
const to = 'HJAoYbnsf16Z8ftk3SsuShKLQQgzmxAPu41RTpjjpump';
const amount = 0.05;

async function swap() {
  const connection = new Connection(rpcUrl, {
    wsEndpoint: wsRpcUrl,
  })
  const transaction = await createTransaction({
    walletAddress: wallet.publicKey.toString(),
    from,
    to,
    amount,
  });

  if (transaction instanceof Error) {
    return transaction;
  }

  transaction.sign([wallet]);

  return sendTransaction(transaction, { connection }) // The fast Cryptoscan method
  // return connection.sendTransaction(transaction); // Solana SDK Method
}

swap().then((tx) => console.log(tx));

FAQ

Is it secure to use sdk with private key?

Yes. You don't share private key through api request. You sign transaction with private key locally only.

Is it free?

We charge a 0.39% fee on each successful transaction instruction. If you want to decrease fee - please contact us in discord or telegram We can increase fee down to 0.1% if you will contribute us.

How to contribute?

You can create pull requests or make a project based on our packages. You have chance to get some supply for a work and get fee reduced for the api.
