Use when adding or auditing crypto checkout, crypto top-up or payment webhooks: invoice states, signed callbacks, idempotent processing, underpayment and rate drift. Not for card billing (stripe-billing). Opt out: no wiring, без обвязки. Triggers - "crypto payment", "USDT payment", "payment webhook", "webhook signature", "underpayment", "приём криптоплатежей", "оплата криптой", "вебхук платежа".
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
# Crypto payments A card charge either succeeds or fails, and the amount is the amount. A crypto payment is a **request that someone may partially satisfy, over-satisfy, satisfy late, or satisfy after the price moved**. Almost every defect in a crypto checkout comes from writing card-shaped code and meeting one of those cases in production. This skill is provider-neutral. Concrete request/response shapes for one gateway live in [`references/heleket-provider.md`](references/heleket-provider.md); the invariants below hold for Coinbase Commerce, NOWPayments, BTCPay, Heleket and anything else that issues an invoice and calls you back. One thing is NOT provider-neutral and is labeled where it appears: the webhook signature *algorithm*, which differs per gateway. > **Choosing a provider is a business and compliance decision, not a technical > one.** Crypto payment processors differ sharply in regulatory standing — > licensing, AML programme, sanctions exposure — and that standing changes. > Check the current position of any processor before you route customer money > through it, and re-check it periodically. This skill tells you how to …

How to install
mdr add ssheleg/sheleg-dev/crypto-payments@sha256:30c1ca0c3182e237The line at the top of this page pins the label git:20261020.6a7c3e1, 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.
