Robinhood Chain guides
Task-based walkthroughs for Robinhood Chain: tracking token transfers, wallet backends, the sequencer feed, conditional submission and debugging reverts — each built on the measured contract, not on assumptions.
Endpoint and plans: Robinhood Chain RPC endpoint.
The method pages describe one call at a time. These guides put several of them together into a working task, and are explicit about the parts of the contract that change how you must write the code — de-duplication, reorgs, recovery after a disconnect.
| Guide | What it covers |
|---|---|
| Track Stock Token transfers | Subscribe to ERC-20 Transfer logs over WebSocket, de-duplicate by (blockHash, transactionHash, logIndex), undo on removed, and backfill a gap with eth_getLogs. |
| Build a wallet backend | Balances, nonce allocation when the pending tag is not a commitment, pricing on a first-come-first-served sequencer, submitting once, and depth-based confirmation without safe/finalized. |
| Consume the sequencer feed | A durable cursor, resuming with from_sequence, reading the resume frame, the three causes of bufferComplete: false, and reconciling a gap through JSON-RPC. |
| Conditional transactions | The five inclusion options, a blockNumberMax deadline from the parent-chain l1BlockNumber, knownAccounts state pinning, and why a local -32602 and the chain's -32003 need different responses. |
Debugging reverts with debug_traceCall | Trace a call that was never sent, decode the revert payload by selector, pin the right block, and where debug_* stops being reliable — best-effort, no SLA, and not a trace_* substitute. |
| Migrate from a public RPC to Triport | What changes when you move off a keyless endpoint: authentication, the methods that appear, WebSocket and feed as new surfaces, the limits that start applying, a rollback that needs no redeploy, and how to benchmark honestly. |
| Index Robinhood Chain activity | Choosing between eth_getLogs and the sequencer feed, keying records so duplicates collapse, computing continuity yourself, tombstoning reorged records, and checkpointing after the work — with two unit-tested example programs. |
Before you start
Every guide assumes you already have a key and a working connection. Read the Quickstart first, and keep Limits nearby — request budgets, the 4 MiB body ceiling and batch accounting apply to everything below.
Terms on this page: Sequencer.
Build a wallet backend for Robinhood Chain
Read native and token balances, allocate nonces safely when the pending tag is not a commitment, price and submit a signed transaction on an FCFS sequencer, and track the outcome by receipt without safe or finalized tags.
POST Conditional transactions on Robinhood Chain
Attach inclusion conditions to a signed transaction with eth_sendRawTransactionConditional: the five supported options, a deadline taken from the parent-chain l1BlockNumber, knownAccounts state checks, and what -32602 and -32003 each mean.
Consume the sequencer feed with cursor-based recovery
Connect to the Robinhood sequencer feed, keep a durable cursor, resume after a disconnect with from_sequence, read the resume frame correctly, and reconcile the range the replay window cannot cover.
Debugging reverts on Robinhood Chain with debug_traceCall
Turn "execution reverted" into a reason: trace a call that was never sent, decode the revert payload, pin the right block, and know where debug_* stops being reliable on this chain.
Index Robinhood Chain activity
Build your own index of Robinhood Chain activity: choose between eth_getLogs and the sequencer feed, key events so duplicates collapse, compute continuity yourself, survive reorgs, and checkpoint so a crash costs a replay instead of data.
Migrate from a public RPC to Triport
Move a Robinhood Chain integration from a keyless public endpoint to Triport: what changes in authentication, which methods you gain, how WebSocket and the sequencer feed are reached, which limits start applying, and how to roll back without a redeploy.
Track Stock Token transfers on Robinhood Chain
Stream ERC-20 Transfer events for tokenized stock contracts on Robinhood Chain over WebSocket, de-duplicate them on the client, handle reorgs, and backfill the gap after a disconnect with eth_getLogs.
