Easy-To-Use Example

import { getWallet } from '@cryptoscan/solana-wallet-sdk';
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

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

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.

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.
