Robinhood Chain RPC API reference

This is the Triport API reference for Robinhood Chain mainnet, chain ID 4663 (0x1237), an EVM-compatible Arbitrum Orbit L2 that pays gas in ETH. It covers 27 catalogued JSON-RPC methods (including four debug_* trace methods), two JSON-RPC WebSocket subscriptions (newHeads and logs), and a separate live sequencer feed. Every request needs an API key, except the shared keyless test URL https://triport.io/public/robinhood — see Public RPC and the free trial key.

Choosing a plan or an endpoint rather than looking up a method? See Robinhood Chain RPC endpoint and plans. Adding the network to a wallet or a config file? See network config (chain ID 4663).

Endpoints

Quickstart

curl https://triport.io/rpc/robinhood \
  -H "x-token: $TRIPORT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

What's available

27 JSON-RPC methods in the OpenRPC catalog:

• robinhood_read_rpc_heavy: 7
• robinhood_read_rpc: 18
• robinhood_send_tx: 2

Account and pending-state reads, block receipts, logs, proofs, four debug methods, and both standard and conditional transaction submission are available through the published catalog. WebSocket subscriptions start at Basic; the live sequencer feed starts at Pro.

The fast path combines a continuously warm earliest-wins receive fan with warm HTTP/WebSocket submission targets; measured latency claims and their limits are documented in Sequencer feed and Fast submission.

Limits

See network limits and Rate Limits & Tiers.

Finite request-rate budgets include a 2× burst buffer at no extra cost. It refills at sustained RPS; there is no quota on the number of bursts. Interval categories use seconds and have no RPS burst. See Burst capacity.

For indexed wallet activity, see address-history availability. A complete address-history API is not currently published for Robinhood.

Errors

See network-specific errors and the shared error reference.

  method: "POST",
  headers: {
    "x-token": process.env.TRIPORT_API_KEY,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}),
});
const { result } = await res.json();
console.log(result);
