Reliability score

How the public score is computed, and when a resolver is removed from fan-out.

Your score is public and ranks you when prices tie. Each rate starts from a prior of 0.9 worth five observations, so a new resolver starts at 0.9 and one bad RFQ does not sink it.

Part	Formula	Weight
Settle rate	Quotes you won that settled, out of settled plus simulation reverts. A revert the keeper traces to the taker’s side is not counted	0.5
Response rate	RFQs you answered (offer or decline) inside the window, out of RFQs sent	0.3
Valid rate	Offers that passed validation, out of offers sent	0.2

The score uses the last 7 days and is recomputed every minute. Its parts are in reliabilityDetail on GET /v1/resolvers/:address.

Automatic removal from fan-out

The relay stops sending you RFQs for one hour when either of these holds:

• Over the last 24 hours, at least 2 of your winning quotes failed the keeper’s simulation and failures exceed 25% of the quotes you won.
• With at least 20 RFQs in the last 7 days, your score is under 0.5.

Counting restarts when the hour ends. The console shows the reason and the time you return, and the app raises an alert. The thresholds are published as thresholds on your console endpoint.

What moves the score

• Answer every RFQ. A decline inside the window is a reply. Silence is not.
• Keep the signer under 700 ms. A slow signer misses the window.
• Keep approvals and balances ahead of your offers. Every rejected offer lowers the valid rate.
• Keep the RPC healthy. A simulation that reverts because your balance moved between offer and settlement counts against the settle rate.
