EthereumPoW (ETHW) API Documentation

EthereumPoW

EthereumPoW (ETHW) is a proof-of-work Layer 1 forked from Ethereum around the September 2022 Merge to preserve proof-of-work consensus. Contracts execute as EVM bytecode against the inherited account-based state model, while full nodes validate proof-of-work blocks and maintain balances, contract storage, transactions, receipts, and logs. Because ETHW retains Ethereum’s EVM and state semantics, standard Ethereum transaction formats, tooling, and JSON-RPC methods remain the main integration baseline.

EthereumPoW API Methods and Endpoints

NOWNodes exposes EthereumPoW's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, WSS (WebSocket) for real-time subscriptions and events, Blockbook for indexed address, balance, transaction, and block lookups, and Trace/Debug for step-level execution analysis.

Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
