Quote shortfall

CoW Protocoln/aUniswapn/a

Every provider is asked for the same swap at the same second, and each answer is scored against the best of that round. The figure is how much less you would have received, in basis points. Quotes are not comparable between rounds: the market moves 30 to 37 bps in five minutes while the field sits inside 25. Two providers take a fee out of the quote and declare it, shown separately: giving up 25 bps to a toll is not routing badly.

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
