Robinhood overview

Robinhood Chain is an Ethereum-compatible Arbitrum Layer 2, chain ID 4663, using ETH for gas. Supanode runs its own node there for JSON-RPC and WebSocket, and indexes decoded on-chain activity into a SQL-queryable warehouse.

RPC & WebSocket

• Standard Ethereum JSON-RPC over HTTPS, eth_subscribe (newHeads, logs) over WebSocket, one x-token for both.
• Debug tracing: debug_traceTransaction, debug_traceCall and the block tracers.
• Blocks, transactions and logs since genesis, state for about the last 5 days.

Indexer

• Uniswap swaps: every v3 and v4 swap decoded - signed token deltas, post-swap price and liquidity, tick, and on v4 the per-swap fee. 200 million swaps across the two versions.
• Uniswap pools: pool creations for both versions, so a pool_id resolves to the pair, fee tier, tick spacing, and on v4 the hooks contract.
• Tokens: ERC-20 identities - name, symbol, decimals, creator, and descriptive metadata. This is what turns an address into something readable.
• Launchpads: eight of them - Pons, Flap, Doppler, Noxa, Nox, Letscash, Varo and Long - each with its launches, its swap stream, and where applicable its bonding-curve trades and graduations.
• Execution context on every row: block number, log index, transaction hash, gas used and the EIP-1559 fee fields, so you can reproduce event ordering and attribute cost without querying a second provider.

Query it directly over ClickHouse SQL, or have us deploy custom REST endpoints for recurring queries.
