Arrow API

API Documentation

Implementations

Here are example implementations showing how to integrate Arrow API into your JavaScript/TypeScript applications.

JavaScriptTypeScript

Create SOL Transfer Transaction Data

Create raw unsigned SOL transfer transaction data using Arrow API. 

import { Transaction } from '@solana/web3.js';

const response = await fetch('https://kouba.io/sol-transfer', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    from_address: fromAddress,
    to_address: toAddress,
    lamports: lamports.toString()
  })
});


let transaction = response.data;

const deserializedTx = Transaction.from(transaction);

const blockhash = await // FETCH YOUR BLOCKHASH HERE //

deserializedTx.recentBlockhash = blockhash;

const serializedTransaction = deserializedTx.serialize({
  requireAllSignatures: false,
});
JavaScriptTypeScript

Create Token Transfer Transaction Data

Create raw unsigned SPL token transfer transaction data using Arrow API. 

import { Transaction } from '@solana/web3.js';

const response = await fetch('https://kouba.io/token-transfer', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    from_address: fromAddress,
    to_address: toAddress,
    token_mint_address: tokenMint,
    amount: amount.toString()
  })
});

let transaction = response.data;

const deserializedTx = Transaction.from(transaction);

const blockhash = await // FETCH YOUR BLOCKHASH HERE //

deserializedTx.recentBlockhash = blockhash;

const serializedTransaction = deserializedTx.serialize({
  requireAllSignatures: false,
});
