Install the Package

Install the Tachyon SDK using your preferred package manager:

npm install @rathfi/tachyon

yarn add @rathfi/tachyon

pnpm add @rathfi/tachyon

Requirements:

• Node.js 16 or higher
• TypeScript 4.5 or higher (if using TypeScript)

Get Your API Key

To use the Tachyon SDK, you'll need an API key:

1. Apply for the API KEY
2. Sign up or log in to your Tachyon account

Basic Setup

Create a new Tachyon instance with your API key:

import { Tachyon } from '@rathfi/tachyon';

const tachyon = new Tachyon({
  apiKey: process.env.TACHYON_API_KEY!, // Store your API key securely
});

Import the SDK

import { Tachyon, ChainId } from '@rathfi/tachyon';

Import the Tachyon class and ChainId enum from the package. The ChainId enum provides type-safe chain identifiers for supported networks.

Initialize the SDK

const tachyon = new Tachyon({
  apiKey: process.env.TACHYON_API_KEY!, // Store your API key securely
});

Create a new Tachyon instance with your API key. Always store your API key in environment variables for security.

Submit a Transaction

const txId = await tachyon.relay({
  chainId: ChainId.BASE,
  to: '0x742d35cc6634C0532925a3b8D1C9b53e6aC3',
  value: '1', // 1 wei
  callData: '0x',
  label: 'My Transaction' // Optional label for tracking
});

console.log('Transaction ID:', txId);

Call the relay() method with your transaction parameters:

• chainId: The target blockchain network
• to: The recipient address
• value: Amount in wei (use '0' for contract calls without value transfer)
• callData: Encoded transaction data ('0x' for simple transfers)
• label: Optional custom label for tracking

Check Transaction Status

const status = await tachyon.getRelayStatus(txId);
console.log('Transaction status:', status);

Use the returned txId to check the current status of your transaction.

Wait for Execution

const executedTx = await tachyon.waitForExecutionHash(txId);
console.log('Execution hash:', executedTx.executionTxHash);

Wait for the transaction to be executed on-chain and get the execution hash.
