Chain support

We currently support several rollups and are open to supporting more.

The following pages provide an overview of these chains and explain specific implementation details in the context of our Architecture.

We support both Optimistic Rollups (Arbitrum, Optimism, Base) and Zero Knowledge (ZK) Rollups (Linea, Scroll, Taiko, zkSync).

The key difference between these two types of chains is:

• Optimistic Rollups: They post state roots to Layer 1 (L1) that can be contested based on chain-specific dispute or fault-proof mechanisms.
• ZK Rollups: They post Zero Knowledge Proofs (ZKP) to L1, which verify the correctness of transaction execution without re-executing all transactions. Once verified on L1, the updated state roots are finalized and cannot be disputed or changed.
