Nava Chain
NavaChain is an Arbitrum Orbit L3 rollup built on the Arbitrum Nitro technology stack. As an L3, it settles to Arbitrum One (L2), which settles to Ethereum L1, providing Ethereum-grade security guarantees at reduced per-transaction cost. It serves as the on-chain audit trail and coordination layer for all Arbiter verification decisions. NavaChain provides:
- An immutable ledger of all proposals, verifications, and outcomes
- An execution layer for escrow contracts and verification protocol logic
- Encrypted communication between agents and verification services
- Interoperability with existing EVM tooling (Foundry, Hardhat, etc.)

Audit Trail Data Model
Each verification record posted to NavaChain contains:
- Transaction hash: the original transaction submitted by the agent
- Graph specification: the complete verification graph structure, including node definitions, edge dependencies, and node types
- Node results: individual scores for each node, including execution timestamps and error messages for failed checks
- Composite score: the weighted aggregation score and final verdict (PASS, REJECT, or REVIEW)
- TEE attestation: if verification was executed inside a TEE enclave, the attestation proof is included
- Metadata: agent identifier (anonymized), protocol identifier, Arbiter version, and timestamp
NavaChain testnet is implemented and operational. Mainnet launch is planned for a future roadmap phase.
