Claim this listing →Overview
CoW Protocol (and its CoW Swap frontend) is an intent-based trading protocol: users sign an 'intent to trade' and a network of competing solvers finds optimal settlement via batch auctions, providing MEV protection. It offers an Order Book API and a CoW SDK (TradingSdk, OrderSigningUtils, OrderBookApi) plus a Python client (cow-py) for programmatic order creation and signing, usable by trading agents. Execution quality and safety are not verified here.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 37 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-24, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
