**APIs profiled:** 1

Zircuit is a zero-knowledge (zk) rollup Layer 2 blockchain and secure onchain finance platform. The network is fully EVM-compatible and OP-Stack based, letting developers deploy standard Solidity smart contracts (via Foundry and the usual Ethereum tooling) while settling to Ethereum with zk validity proofs. Zircuit exposes standard Ethereum JSON-RPC endpoints for mainnet (chain ID 48900) and the Garfield testnet (chain ID 48898), a canonical L1<>L2 bridge, a relayer service (EIP-7702 gasless relaying), a transaction simulation surface, and the GUD Trading Engine — a REST API that aggregates cross-chain liquidity to return best-execution quotes and signable transaction data. On top of the chain, Zircuit Finance and the Liquidity Hub offer institutional-grade yield and LST/LRT staking. Backed by Pantera Capital; the network and contracts have been audited by six independent security firms and run a bug-bounty program.
