Use when moving crypto out of cold storage and the signing key must never touch an internet-connected machine; models the round trip where an intent crosses a QR or SD gap and the offline vault re-derives the approval display itself.
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 when a treasury process, withdrawal pipeline, or trading-bot funding job must move crypto out of cold storage, and the signing key must never exist on an internet-connected machine. It models the full round trip — coordinator issues an intent, the intent crosses an air gap on QR or SD media, an offline vault displays and signs it, the envelope comes back, the coordinator verifies the binding and submits it exactly once. The controls it encodes are the ones that survive a compromised online host: the vault derives what the human sees from the exact bytes it is about to sign, enforces its own policy and its own replay ledger, and the intent is bound to an EIP-155 chain id rather than to a network label. It exists because the expensive failures in this workflow are not broken cryptography. They are a signer approving a screen that described a different transaction, and an operator retrying a broadcast whose response was merely lost. ## When NOT to Use - **As a transaction builder.** `UnsignedPayload` is a transfer *intent*, not a signable Ethereum transaction. It carries no gas parameters, no `data` field, …

How to install
mdr add himanshuj16/algo-trading-skills/air-gapped-signing-workflow-for-cold-storage@sha256:f79a7d944d285c63The 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.
