The problem
O1 Exchange needed a swap router on Base. It had to find the best price across 15+ venues and complete each swap in milliseconds.
An order goes into the quote API. Beam search drops weak routes. The convex optimizer splits the order across venues: two shown, plus 13 or more. The Solidity router batches the legs into one swap.
Beam search drops a weak route before the optimizer splits the order.
What we built
- Multi-hop routing with permit-enabled swaps.
- The o1 launchpad on Uniswap v4, with locked liquidity and RWA tokenization.
The result
On benchmark trades, the router's prices stay within 30bp of the top aggregators.
