Choosing Your Adapter: viem vs. ethers

The SDK is designed to work with both viem and ethers.js, the two most popular Ethereum libraries. Since the SDK offers identical functionality for both, the choice comes down to your project’s needs and your personal preference.

​
The Short Answer (TL;DR)

  • If you’re adding the SDK to an existing project: Use the adapter for the library you’re already using.
  • If you’re starting a new project: The choice is yours. viem is generally recommended for new projects due to its modern design, smaller bundle size, and excellent TypeScript support.
You can’t make a wrong choice. Both adapters are fully supported and provide the same features.

Deposit (L1 → L2)

L1 → L2 deposit — submit a deposit, and monitor until confirmed.

Withdrawal (L2 → L1)

L2 → L1 withdrawal — submit a withdrawal, and monitor until readied.

What you’ll do

Each Quickstart walks you through how to:
  1. Install the adapter package.
  2. Configure a client or signer.
  3. Run a deposit (L1 → L2) or withdrawal (L2 → L1) as a working example.
  4. Track the status until it’s complete.
