Robinhood Chain

Description

A $100,000 stock-token order on Robinhood Chain sent to the best single pool left a median $199 on the table in 6,329 of 7,493 executable quotes. partitio splits it and floors the fill against Chainlink. Those are quotes, not executions, from runs 1 to 245 between September 24 and 27, 2026, and they recompute offline from the repo.

partitio quotes every committed pool for a stock and splits the order only when that beats the best single pool. The contract checks every fill against Chainlink and reverts outside the band. Users sign twice and hold no ETH, because a relayer pays the gas: buys are funded by USDG's EIP-3009 authorization, sells by the stock token's EIP-2612 permit.

It is live on Robinhood Chain mainnet. The router commits to 161 venues across Uniswap v3, Uniswap v4 and maker pairs by an immutable Merkle root, and binds 35 tokens to their Chainlink feeds. Both contracts are ownerless and verified on Sourcify. Two round trips have filled on mainnet from a demo wallet that has never held ETH, and the demo video shows the second.

Every claim can be checked in five minutes with the judge guide at the top of the repo. The beta caps trades at $50, and aggregator routes are not compared.

Progress During Hackathon

Everything here was built during the buildathon, starting with the first commit on September 24, 2026. September 24 to 27: an evidence engine that quotes 18 stock tokens at four sizes about every 20 minutes, on-chain, venue by venue. Runs 1 to 245 produced 34,562 quote rows and 4,392 Chainlink references. An independent review of the contracts found 12 issues, one critical and one high. Both were fixed, and all 12 were closed before deployment. A follow-up audit of the fixes found 12 more, and the deploy went out with nothing high or critical open. 159 Foundry tests pass, and Medusa fuzzing ran with 0 failures. September 27: PartitioRouterV2 and GaslessEntry deployed on Robinhood Chain mainnet, exact match on Sourcify, and the relayer went live at partitio.ochinimus.app. September 28: two mainnet round trips, AAPL bought with USDG and sold back, from a wallet that has never held ETH. A builder feedback file in the repo records five issues we hit on Robinhood Chain, Paxos USDG and the price feeds, each with its evidence.
