aid: blast-network url: https://raw.githubusercontent.com/api-evangelist/blast-network/refs/heads/main/apis.yml name: Blast kind: company description: >- Blast is an Ethereum Layer 2 network (OP Stack-derived, post-Pacific Meridian upgrade) that pays native yield on bridged ETH and stablecoins via auto- rebasing tokens — roughly 4% on ETH (from Ethereum staking) and 5% on USDB (from T-Bill protocols) — and programmatically returns a share of net gas revenue to dApps. Mainnet runs at chain ID 81457 with public JSON-RPC at rpc.blast.io and a Sepolia testnet at chain ID 168587773 / sepolia.blast.io. Developer surfaces include Blastscan and Sepolia Blastscan explorers, the native bridge, USDB stablecoin, and the gas / yield smart contracts. image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Blockchain - Layer 2 - Ethereum - EVM - Native Yield - Rebasing - OP Stack created: '2026-05-23' modified: '2026-05-23' specificationVersion: '0.19' apis: - aid: blast-network:mainnet-rpc name: Blast Mainnet JSON-RPC description: >- Public Ethereum-compatible JSON-RPC endpoint for Blast mainnet (chain ID 81457).
