}

eth_getCode — return account bytecode at a block. The published signature and response shape come from the measured Robinhood OpenRPC contract (chain ID 4663).

Distinguish a contract from an EOA and detect a deployment at a given block. Empty bytecode means no contract at that block, not that it never existed — and a historical block below the measured archive floor is not served at all, which is a different answer from "no code".

Parameters

JSON-RPC params is a positional array.

addressAddressrequired

Account or contract address (20-byte hex).

blockBlockTagrequired

Block number in hex, or a tag: latest, earliest, pending. safe and finalized are not part of this contract.

Response

A measured response from Robinhood Chain mainnet.

Errors

See Robinhood errors. Invalid parameters return a JSON-RPC parameter error; authentication and rate-limit failures use the shared client error contract. Unknown failures are returned without an implicit retry.

Examples

JavaScript

const response = await fetch("https://triport.io/rpc/robinhood", {
  method: "POST",
  headers: { "x-token": process.env.TRIPORT_API_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({"jsonrpc":"2.0","id":1,"method":"eth_getCode","params":["0x0000000000000000000000000000000000000000","latest"]}),
});
const payload = await response.json();

Notes

Empty bytecode answers "no contract at that block", which is not the same as "never existed".
Below the measured archive floor the block is not served at all — a different outcome from an empty result.
