**APIs profiled:** 9

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 (9)

- **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.
- **Blast JSON-RPC API** — Ethereum-compatible JSON-RPC methods exposed by the Blast node.
