  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.
