Endpoint and plans: Robinhood Chain RPC endpoint.

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

The native ETH balance at a chosen block. For token balances call the token contract with eth_call; this method never reads ERC-20 state. A historical block only answers above the measured archive floor — block 55,782,445 on the earliest channel, 56,772,445 on another (direct-channel measurement, September 2026).

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

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_getBalance","params":["0x0000000000000000000000000000000000000000","latest"]}),
});
const payload = await response.json();

Notes

  • Native ETH only. ERC-20 balances live in contract storage and need eth_call.
  • Historical blocks answer only above the measured archive floor — 55,782,445 on the earliest channel, 56,772,445 on another (direct-channel measurement, September 2026).
