Clients

Clients are libraries used to interact directly with the blockchain, for example, to deploy, call, and manage smart contracts.

LightLink is fully EVM-equivalent, and developers can use their usual Ethereum clients.

ethers.js

To use ethers.js in LightLink projects, you need to add LightLink's JSON RPC URL. In your project code, find this code and change the 'url' constant to:

const url = 'https://replicator.phoenix.lightlink.io/rpc/v1';
const provider = new ethers.providers.JsonRpcProvider(url);

To connect with the Testnet, insert the following:

const url = 'https://replicator.pegasus.lightlink.io/rpc/v1';
const provider = new ethers.providers.JsonRpcProvider(url);

thirdweb's SDK

To connect thirdweb SDK with LightLink Mainnet, add this code to your project:

import { LightlinkPhoenix } from "@thirdweb-dev/chains";
import { ThirdwebSDK } from "@thirdweb-dev/sdk";

// If used on the FRONTEND pass your 'clientId'
const sdk = new ThirdwebSDK(LightlinkPhoenix, {
  clientId: "YOUR_CLIENT_ID",
});
// --- OR ---
// If used on the BACKEND pass your 'secretKey'
const sdk = new ThirdwebSDK(LightlinkPhoenix, {
  secretKey: "YOUR_SECRET_KEY",
});

const contract = await sdk.getContract("0x0000000000000000000000000000000000000000");

To connect with the Testnet, add this code:

import { LightlinkPegasusTestnet } from "@thirdweb-dev/chains";
import { ThirdwebSDK } from "@thirdweb-dev/sdk";

// If used on the FRONTEND pass your 'clientId'
const sdk = new ThirdwebSDK(LightlinkPegasusTestnet, {
  clientId: "YOUR_CLIENT_ID",
});
// --- OR ---
// If used on the BACKEND pass your 'secretKey'
const sdk = new ThirdwebSDK(LightlinkPegasusTestnet, {
  secretKey: "YOUR_SECRET_KEY",
});

const contract = await sdk.getContract("0x0000000000000000000000000000000000000000");

web3.js

To use web3.js with LightLink Mainnet, initialize a new web3 object:

const Web3 = require('web3');
const web3 = new Web3('https://replicator.phoenix.lightlink.io/rpc/v1');

To connect with the Testnet, use the following initialization:

const Web3 = require('web3');
const web3 = new Web3('https://replicator.pegasus.lightlink.io/rpc/v1');

Other EVM-compatible clients should also work with LightLink, provided the correct RPC node addresses are used.
