SDK

Overview

The EES SDK is a Node library to interact with the EES protocol in a typescript/javascript environment. It is built with viem and contains functionality that makes it easy to query data from and interact with the EES contracts among other features. The implementation can be found here.

Interactions requiring querying on-chain data require the user to supply a viem public client. Some functionality like executing a job or generating a sponsor signature requires the user to additionally supply a viem wallet client.

Installation and setup

The SDK can be installed through npm.

npm i --save ees-sdk

After installation, the SDK contains a class called EESSDK which can be initialized as follows:

index.ts

import { EESSDK } from 'ees-sdk';
import { publicClient, walletClient } from "./config";

const eesSDK = new EESSDK(publicClient, walletClient);

config.ts

import { createPublicClient, createWalletClient, http, PublicClient, WalletClient } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { baseSepolia } from 'viem/chains';

export const publicClient: PublicClient = createPublicClient({
  chain: baseSepolia,
  transport: http()
}) as PublicClient;

export const walletClient: WalletClient = createWalletClient({
  account: privateKeyToAccount('0x...'),
  chain: baseSepolia,
  transport: http()
});

Now you are ready to start interacting with EES!

Careful: Remember to never store your private key and RPC URL in plain text in your project.

Note: The EES protocol is currently only deployed on the Base Sepolia network.
