Reference

This section documents the low-level APIs exposed by the SDK.
Unlike the high-level flows (deposits, withdrawals), these helpers give you direct access to ZKsync-specific contracts and RPC methods.

What you’ll find here

  • ZKsync RPC Helpers
    A typed interface around ZKsync zks_ JSON-RPC methods such as:

    • getBridgehubAddress()
    • getL2ToL1LogProof()
    • getReceiptWithL2ToL1()
    • getGenesis()

  • Common Helpers
    Utility getters for frequently used contracts and addresses, such as:

    • l1AssetRouter(), l1Nullifier(), l1NativeTokenVault()
    • baseToken(chainId)
    • l1TokenAddress(l2Token), l2TokenAddress(l1Token)
    • assetId(l1Token)
