Network details

Try it without a key

Robinhood Chain is one of six networks with a keyless Triport endpoint. Point a script or a wallet at it to see real answers before creating a key: reads include the heavy category, so debug_* traces and eth_getProof answer on it. trace_* and txpool_* are not part of the Robinhood contract, state at the very first blocks is outside coverage, and there is no WebSocket and no sequencer feed. The budget is one for everyone and has no per-IP share, so production traffic belongs on a key.

curl https://triport.io/public/robinhood \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'
# -> {"jsonrpc":"2.0","id":1,"result":"0x1237"}

Which endpoint for which job

How the network's public URL differs from a keyed endpoint: Robinhood Chain public RPC vs a keyed endpoint. Starting without a paid plan: public RPC and the free trial key. Other providers on the same network: Robinhood Chain RPC providers compared.

What is available

JSON-RPC — 27 methods

18 standard reads, 7 heavy reads and 2 submission routes, including eth_getBlockReceipts, eth_getProof and four debug_* trace methods. Full list: Robinhood JSON-RPC reference.

WebSocket — newHeads and logs

Available from Basic with scope robinhood:rpc. newHeads is served from a shared warm header layer; logs takes an address/topic filter. newPendingTransactions is not available, and robinhood_pendingBlock is an operator-controlled extension that is disabled by default. See WebSocket.

Sequencer feed — assembled L2 blocks

From Pro with scope robinhood:feed: 2 concurrent streams on Pro, 4 on Business and Enterprise. Reconnect with ?from_sequence=<cursor>; the first frame reports earliestAvailableSequence, latestAvailableSequence and bufferComplete. See Sequencer feed.

What is specific to Triport here

• Four debug_* trace methods in the published catalog — best-effort, without an availability SLA.
• eth_getBlockReceipts for whole-block receipt reads instead of per-transaction fan-out.
• Feed resume by cursor with an explicit bufferComplete flag, so a gap is visible instead of silent.
• A continuously warm receive fan that publishes the first arrival per sequenceNumber and deduplicates later copies — it trims the per-socket tail, not a promised average.
• JSON-RPC bodies and batches up to 4 MiB; every batch element is checked, and N elements cost N requests.
• Flat monthly price with no compute units and no per-call credits.

Quickstart

# curl
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":[]}'

# viem
import { createPublicClient, defineChain, http } from "viem";
const robinhood = defineChain({
  id: 4663,
  name: "Robinhood Chain",
  nativeCurrency: { name: "Ether", symbol: "ETH", decimals: 18 },
  rpcUrls: { default: { http: ["https://triport.io/r/<API_KEY>/robinhood"] } },
});
const client = createPublicClient({ chain: robinhood, transport: http() });

# ethers v6
new ethers.JsonRpcProvider("https://triport.io/r/<API_KEY>/robinhood", 4663);

# Hardhat / Foundry
networks: { robinhood: { url: "https://triport.io/r/<API_KEY>/robinhood", chainId: 4663 } }
rpc_endpoints = { robinhood = "https://triport.io/r/<API_KEY>/robinhood" }

Wallets and config files cannot send custom headers, so they use the keyed URL form; server code should send the x-token header instead and keep the key out of URLs and logs.

Limits and plans

2× burst buffer, included. Finite request-rate limits show sustained RPS and short burst capacity. A full buffer at 20 RPS can absorb up to 40 requests at once and refills at 20 requests per second. There is no quota on the number of bursts and no extra charge for them. Size ongoing traffic to sustained RPS. Categories with no per-category cap have no numeric burst ceiling. How burst capacity works.

Bodies and WebSocket messages are capped at 4 MiB; an oversized batch returns HTTP 413 batch_too_large. Plans: Basic $20, Pro $249, Business $499, Enterprise from $999 per month; Free is a 7-day trial with a single key in the EU region, not a permanent plan. See network limits.

Every plan with its limits on every network, and what a plan costs at its cap: RPC pricing.

What is not in the product yet

Transactions are submitted to the sequencer intake; a returned hash means the request was routed, and the receipt decides inclusion. See submission and conditional transactions. The Conditional Transactions API page shows which block number the bounds are compared with and what each response means.
