BaiBai is a market-maker exchange on Base: professional makers post their own price curves on chain, and anyone swaps against them through one entrypoint, with no pool, no passive liquidity, and no order to sign.

The price is the maker's, refreshed as fast as the maker moves. Each market posts a signed piecewise-linear curve around a mid, with a spread and depth on each side, valid for seconds rather than blocks, so the quote a taker fills at tracks the maker's own book instead of a reserve ratio that only moves when someone trades into it. A swap walks that curve atomically: the whole amount fills at the posted price or the transaction reverts, and the output is paid straight from the makers' pooled inventory.

A price that fresh only helps the flow that is there to take it. The swap that went through a pool at a wider spread because the maker's curve was not the venue anyone checked. The rebalance that waited for a person while the maker's quote sat inside the market. The exit sized by hand against a curve whose depth had already moved.

The entrypoint's own quote view is a step a plug can read, so a swap on a BaiBai market is floored at what the maker's curve pays at that moment, can be gated on beating another venue's quote in the same run, and executes when a condition is met rather than when someone is at the keyboard.

A position trimmed into the maker's bid the moment a price crosses a mark. A stablecoin balance rotated into the base at the maker's ask on a schedule. A swap that takes the maker's spread only when it prices better than the pool beside it.

The flow that fills against market makers on Base already moves this way, because the venue quoting tightest right now is not something a person can keep in their head.
