Ethereum Classic
Ethereum Classic (ETC) is a proof-of-work Layer 1 smart contract network compatible with the EVM, with the Thanos upgrade in November 2020 modifying its mining algorithm after the network’s 2020 attacks. Solidity and other EVM languages compile to bytecode executed against Ethereum-style account state, while full nodes maintain balances, contract storage, blocks, receipts, and logs. Its continued EVM compatibility means Ethereum tooling, transaction formats, and JSON-RPC conventions remain applicable even though consensus differs from proof-of-stake Ethereum.
Ethereum Classic API Methods and Endpoints
NOWNodes exposes Ethereum Classic's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, 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.
