Settlement Contracts

Settlement contracts enable ZKsync chains to settle transaction batches and communicate with Ethereum L1.

• L1 <> L2 communication: Handles deposits, withdrawals, and censorship-resistant message passing between L1 and L2
• Data availability: Manages how L2 state data is made available, supporting various modes from full on-chain data to custom DA solutions

For the broader context of how these contracts fit into the L1 architecture and more details on settlement process itself, see L1 Smart Contracts.
