Zircuit

aid: zircuit
name: Zircuit
description: 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.

  description: Standard Ethereum JSON-RPC 2.0 interface to the Zircuit L2 network (HTTP and WebSocket) for reading chain state
    and submitting transactions. Mainnet is chain ID 48900; the Garfield testnet is chain ID 48898. EVM-compatible, so the
    full eth_* / net_* / web3_* method set applies. DRPC additionally offers paid high-performance node access with debug
    traces.
