Overview

The @zksync-sdk is a lightweight extension for viem and ethers that makes ZKsync cross-chain actions simple and consistent.

Instead of re-implementing accounts or RPC logic, this SDK focuses only on ZKsync-specific flows:

• Deposits (L1 → L2)
• Withdrawals (L2 → L1, with finalization)
• Status & wait helpers
• ZKsync specific JSON-RPC methods

What you’ll find here

• What this SDK does — the purpose, scope, and non-goals.
• Mental model — how to think about the core methods (quote → prepare → create → status → wait → finalize).
• Adapters (viem & ethers) — how the SDK integrates with your existing stack.
