LayerZero V2 Solana OFT SDK

You can use the Solana OFT SDK - @layerzerolabs/oft-v2-solana-sdk library to interact with your Solana OFT.

Setting up a project using the LayerZero CLI would have given you scripts under the tasks/solana folder that utilizes the Solana OFT SDK. You can refer to tasks/solana/sendOFT.ts for the example usage.

Using the Solana OFT SDK in the Frontend

The Solana OFT SDK was recently updated (in version 3.0.57) to be more browser-compatible. Versions prior to this required more additional configurations via your bundling tool.

From 3.0.57 onwards, you can use the Solana OFT SDK with these minimal configurations:

Next.js

// next.config.ts
import type {NextConfig} from 'next';

const nextConfig: NextConfig = {
  webpack: (config) => {
    config.resolve.fallback = {
      fs: false,
      module: false,
    };
    return config;
  },
};

export default nextConfig;

Vite

// vite.config.ts
import {defineConfig} from 'vite';
import react from '@vitejs/plugin-react';
import {nodePolyfills} from 'vite-plugin-node-polyfills';

// https://vite.dev/config/
export default defineConfig({
  plugins: [react(), nodePolyfills()],
});

Compatibility with @solana/web3.js

Under the hood, uses @metaplex-foundation/umi, which is an alternative to @solana/web3.js.

If your project is using @solana/web3.js, you can utilize adapters for @solana/web3.js.
