# Linea

**Canonical:** https://apis.io/providers/linea-network/  
**Website:** https://linea.build  
**APIs profiled:** 10

Linea is an Ethereum zkEVM Layer 2 developed by Consensys, offering full Ethereum equivalence under a zero-knowledge proving system that finalizes state to Ethereum L1. Linea mainnet runs at chain ID 59144 with public JSON-RPC at rpc.linea.build, and a Sepolia testnet at chain ID 59141 at rpc.sepolia.linea.build. Developer surfaces include Linea-specific JSON-RPC extensions (linea_estimateGas, linea_getProof), the Linea SDK, the canonical Linea Bridge, Lineascan block explorer, the Linea POH/attestation system, and a published Linea Stack for deploying Linea-equivalent chains.
