Use when strategies depend on a custody provider being able to sign right now, tracking API uptime against the contractual target, the MPC signing quorum with warning at zero redundancy, and P99 signing latency.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use Use this skill on institutional crypto desks whose automated strategies depend on a custody provider being able to *sign right now*. In 24/7 crypto markets a custody outage or an MPC quorum failure during a volatility spike blocks margin top-ups and liquidation defence, and the loss is realized before a human notices. The engine consumes health-probe telemetry and answers one question — is the primary custodian live enough to sign, and if not, should we fail over? It reports: - **Uptime** against your *contractual* target, compared without a rounding step that could mask a breach. - **MPC quorum** for a k-of-n signing cluster, including a `QUORUM_AT_RISK` warning at zero remaining redundancy — before the halt, not during it. - **P99 signing latency**, gated on having enough samples for a 99th percentile to mean anything. **It fails closed.** No telemetry, stale telemetry, and malformed telemetry are all non-healthy outcomes that recommend failover. Silence is not health. ## When NOT to Use …

How to install
mdr add himanshuj16/algo-trading-skills/custody-solution-uptime-and-liveness-guarantees@sha256:c580c9adfc7cce90The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
