  "result": "0x0"
}

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

The account nonce, which is what you need before signing a transaction. At the pending tag the value reflects a right-now view, not a commitment. Because sequencing here is first-come, first-served, a nonce you read and immediately use is the normal path — there is no fee auction to lose.

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

Notes

At pending the count includes transactions not yet mined, so it is a right-now view rather than a commitment.
Sequencing is FCFS, so a nonce read and used immediately is the normal path; there is no fee auction to lose it to.
