🚀 micro-ethers JavaScript SDK 🚀

In order to provide easy access to all the features of micro, the micro-ethers JavaScript SDK was created, which is made in a way that has an interface very similar to those of ethers. In fact, ethers is a peer dependency of our library and most of the objects exported by micro-ethers ( e.g. Wallet, Provider etc.) inherit from the corresponding ethers objects and override only the fields that need to be changed.

While most of the existing SDKs should work out of the box, deploying smart contracts or using unique micro features, like account abstraction, requires providing additional fields to those that Ethereum transactions have by default.

The library is made in such a way that after replacing ethers with micro-ethers most client apps will work out of box.

📌 Overview

To begin, it is useful to have a basic understanding of the types of objects available and what they are responsible for, at a high level:

• Provider provides connection to the micro blockchain, which allows querying the blockchain state, such as account, block or transaction details, querying event logs or evaluating read-only code using call. Additionally, the client facilitates writing to the blockchain by sending transactions.
• Wallet wraps all operations that interact with an account. An account generally has a private key, which can be used to sign a variety of types of payloads. It provides easy usage of the most common features.

🛠 Prerequisites

• node: >= 18 (installation guide)
• ethers: ^6.7.1

📥 Installation & Setup

yarn add micro-ethers
yarn add ethers@6 # ethers is a peer dependency of micro-ethers

📝 Examples

The complete examples with various use cases are available here.

Connect to the micro network:

import { Provider, utils, types } from "micro-ethers";
import { ethers } from "ethers";

const provider = Provider.getDefaultProvider(types.Network.Goerli); // micro testnet (L2)
const ethProvider = ethers.getDefaultProvider("goerli"); // goerli testnet (L1)

Get the latest block number

const blockNumber = await provider.getBlockNumber();

Get the latest block

const block = await provider.getBlock("latest");

Create a wallet

const PRIVATE_KEY = process.env.PRIVATE_KEY;
const wallet = new Wallet(PRIVATE_KEY, provider, ethProvider);

Check account balances

const ethBalance = await wallet.getBalance(); // balance on micro network

const ethBalanceL1 = await wallet.getBalanceL1(); // balance on goerli network

Transfer funds

Transfer funds among accounts on L2 network.

const receiver = Wallet.createRandom();

const transfer = await wallet.transfer({
    to: receiver,
    token: utils.ETH_ADDRESS,
    amount: ethers.parseEther("1.0"),
});

Deposit funds

Transfer funds from L1 to L2 network.

const deposit = await wallet.deposit({
    token: utils.ETH_ADDRESS,
    amount: ethers.parseEther("1.0"),
});

Withdraw funds

Transfer funds from L2 to L1 network.

const withdrawal = await wallet.withdraw({
    token: utils.ETH_ADDRESS,
    amount: ethers.parseEther("1.0"),
});
