How the floor works

Onchain state is authoritative for balances, ownership, fees, launch progress, settlement, and receipts. The database is a non-authoritative cache, policy store, and audit log.

Chains

Robinhood Chain (mainnet): Chain ID 4663 · gas ETH · writes enabled

Robinhood Chain is an EVM-compatible Arbitrum L2. Production reads go through a dedicated server-side RPC proxy; public endpoints are read-only fallbacks and are never treated as production infrastructure.

Launch engine

The application never calls a factory ABI directly. Everything goes through a provider-neutral LaunchEngine interface that returns typed supported, unsupported, blocked, stale, and error states and fails closed.

uniswapLiquidityLauncherUnavailable

Pending verification

The only production candidate. Uses the official, version-pinned Uniswap Liquidity Launcher SDK to derive supported deployments and build transactions. Only launch mechanisms and quote combinations the SDK and verified contracts actually support are offered. Calldata is never improvised for an unsupported pair.

mockCurveUnavailable

Testnet and demo only

A deterministic, clearly-labelled adapter for UI development and browser tests. It never appears as a live mainnet market and never creates mainnet transactions.

customAuditedCurveUnavailable

Disabled stub

Reserved for a future audited custom curve. Enabled only when the owner supplies source, licensing permission, verification details, audit reports, and deployed addresses.

Contract manifest

Every required address is declared in a typed manifest carrying chain ID, contract role, address, ABI or source hash, expected bytecode hash, creation block, SDK version, explorer link, verification status, enabled environment, and last verification timestamp.

At startup and in the admin release check we confirm each address has contract code and matches the approved manifest. On mismatch, reads may continue but every write is disabled. No address from any reference project is reused.

Fee model

Protocol fee: Unavailable
Launch fee: Unavailable
LP fee: Unavailable
Network fee (ETH): Unavailable
Creator economics: Unavailable

Fees are bounded in both the interface and the contracts, and are itemised before any signature. Values remain unavailable until a verified deployment publishes them.

Data sources

Robinhood asset registry: Official assets endpoint — symbol, contract, decimals, ISIN, status.
Robinhood reference prices: Official per-symbol price endpoint — indicative offchain reference only.
Corporate actions: Official corporate-action data — multiplier and pause state.
Onchain reads: Robinhood Chain via a server-side RPC proxy — balances, code, oracle answers, sequencer state.
Indexed events: Confirmed logs keyed by chain, transaction hash, and log index, with reorg handling.
