Contract Bytecode of an Address on an EVM Chain

evmrpc/contract-code

The bytecode deployed at an address at the newest block, whether it is a contract (any code at all; an externally owned account that delegates to code under EIP-7702 also reads as one), and the size in bytes. The code is cut at 100,000 hex digits. Read from public nodes that offer no SLA and can be slow, throttled or a block behind; a failing node is replaced by another operator's automatically. Served by Eden Engine; not an official product of any chain or node operator.
