GenLayerJS

👀 About

GenLayerJS SDK is a TypeScript library designed for developers building decentralized applications (Dapps) on the GenLayer protocol. This SDK provides a comprehensive set of tools to interact with the GenLayer network, including client creation, transaction handling, event subscriptions, and more, all while leveraging the power of Viem as the underlying blockchain client.

Prerequisites

Before installing GenLayerJS SDK, ensure you have the following prerequisites installed:

• Node.js (>= 16.x)
• npm (>= 7.x)

🛠️ Installation and Usage

To install the GenLayerJS SDK, use the following command:

$ npm install genlayer-js

Here’s how to initialize the client and connect to the GenLayer Simulator:

Reading a Transaction

import { simulator } from 'genlayer-js/chains';
import { createClient } from "genlayer-js";

const client = createClient({
  chain: simulator,
});

const transactionHash = "0x...";

const transaction = await client.getTransaction({ hash: transactionHash })

Reading a contract

import { simulator } from 'genlayer-js/chains';
import { createClient } from "genlayer-js";

const client = createClient({
  chain: simulator,
});

const result = await client.readContract({
  // account: account, Account is optional when reading from contracts
  address: contractAddress,
  functionName: 'get_complete_storage',
  args: []
  stateStatus: "accepted",
})

Writing a transaction

import { simulator } from 'genlayer-js/chains';
import { createClient, createAccount } from "genlayer-js";

const client = createClient({
  network: simulator,
});

const account = createAccount();
const transactionHash = await client.writeContract({
  account: account, // using this account for this transaction
  address: contractAddress,
  functionName: 'account',
  args: ['new_storage'],
  value: 0, // value is optional, if you want to send some native token to the contract
});

const receipt = await client.waitForTransactionReceipt({ hash: txHash, status: TransactionStatus.FINALIZED}) //or ACCEPTED

🚀 Key Features

• Client Creation: Easily create and configure a client to connect to GenLayer’s network.
• Transaction Handling: Send and manage transactions on the GenLayer network.
• Wallet Integration*: Seamless integration with MetaMask for managing user accounts.
• Gas Estimation*: Estimate gas fees for executing transactions on GenLayer.
