Aquifer is a pricing and execution layer for tokenized equities on Robinhood Chain (chain ID 4663). It discovers every liquidity pool for a given equity token across the venues deployed on the chain, reads each pool’s price, liquidity, fee, and tick data directly from contract storage via batched eth_call, and simulates a specific order size against that state rather than quoting a midpoint. Because concentrated-liquidity pools price differently at different sizes, Aquifer walks the order through each pool’s tick ladder to determine the fill a trader would actually receive. It then allocates the order across venues by marginal price until no remaining slice would execute better elsewhere. Every response includes the block number it was read at, making quotes reproducible. The project consists of a web terminal, a keyless public REST API, an Android application, and an on-chain router contract that executes multi-venue splits in a single transaction. Coverage currently spans eleven instruments — SPY, QQQ, NVDA, AAPL, TSLA, MSFT, GOOGL, AMZN, META, AMD, and PLTR — quoted against USDG.
