What is the Anchor Score?
The Anchor Score (ACR) is a composite, on-chain operational trust signal for Stellar anchors. It represents the actual fundamental health of an anchor's infrastructure, entirely removing the need for them to lock up capital.
Our Risk Oracle aggregates off-chain metrics — SEP-24 settlement success, withdrawal latency, and oracle uptime — and pushes them to the smart contract to calculate an immutable, multi-dimensional score readable by any protocol on Stellar.
// get composite operational score

// 10000 bps = 100.00% confidence
Rating Scale
RatingScore RangeSignal
AAA95% – 100%Exceptional — Flawless settlement rates and sub-minute latency.
AA90% – 95%Strong — Highly reliable. Minor operational friction.
A80% – 90%Standard — Adequate buffer for isolated network events.
BBB70% – 80%Marginal — Elevated failure rates or high latency.
C< 70%Low confidence — Avoid routing funds.
