Blast

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.

APIs

Blast Mainnet JSON-RPC

Public Ethereum-compatible JSON-RPC endpoint for Blast mainnet (chain ID 81457). Supports the standard eth_* method set used by web3 clients, wallets, and indexers.

Blast Sepolia Testnet JSON-RPC

Public JSON-RPC endpoint for the Blast Sepolia testnet (chain ID 168587773), used for application development, integration testing, and bridge testing before deploying to mainnet.

Blast Native Yield Contracts

Auto-rebasing yield mechanism for ETH and USDB on Blast. Contracts expose configuration calls to opt accounts into automatic, claimable, or void yield modes, used by every dApp ...

Blast Gas Revenue API

Programmatic interface for dApps to claim back a share of the net gas revenue generated by their contracts on Blast, configured per-contract via the Blast precompile.

USDB Native Stablecoin

USDB is Blast's native auto-rebasing stablecoin, redeemable 1:1 for DAI when bridged back to Ethereum. Backed by T-Bill protocols and integrated directly into the Blast bridge.

Blast Bridge

Canonical Ethereum-Blast bridge for ETH, USDB, and supported ERC-20 tokens. UI lives at bridge.blast.io and is backed by the OP Stack standard bridge contracts.

Blastscan Block Explorer

Etherscan-style block explorer for Blast mainnet — transactions, blocks, addresses, contracts, tokens, and Solidity source verification.

Blastscan Sepolia Testnet Explorer

Blastscan instance for the Blast Sepolia testnet, supporting transaction lookup and contract verification for testnet deployments.
