How Route API ranks 30 chains in under 400ms
A look at the quote engine behind Route API, and how it prices a route across 30 chains that fast.
The problem
Ranking a route across 30 chains means pricing gas, liquidity, and bridge fees for every candidate path before a user’s quote request times out.
The approach
Weir keeps a warm cache of gas and liquidity data per chain, refreshed on a rolling interval, so a quote request only needs to price the top candidates in full.
The result
Median quote time holds under 400 ms even as the routing graph has grown from 18 to 30 chains.
