Cryptocurrency & Crypto Payments Security

Irreversibility changes everything. In crypto payments, a single bad transaction can settle in seconds with no clawback path. The goal of this workflow is to stop high-blast-radius mistakes before signing, then produce auditable triage when automation cannot prove safety.

What this workflow covers

  • Wallet-op hardening for hot-wallet signing services.
  • Address integrity controls to prevent substitution and poisoning.
  • Key-material cleanup in code, logs, CI artifacts, and runbooks.
  • Settlement policy checks before release and after chain events.

Eligibility profile

A finding is agent-eligible when all are true:

  1. The fix shape is bounded (policy/config, controlled code path, or deterministic runbook update).
  2. A signed transaction is not emitted directly by the agent.
  3. A dry-run or simulation path exists.
  4. Human approval remains mandatory for production key use.

Recipe catalog

Use the following prompt recipes for this workflow:

Guardrails

  • Signer credentials are scoped to simulation-only in agent runs.
  • Allowlists enforce destination, chain, token, amount, and cadence.
  • Every fail-open branch is converted to fail-closed with triage.
  • Incident evidence is written to immutable audit storage.

Not in scope

  • Autonomous treasury strategy decisions.
  • Trading or market-making actions.
  • On-chain signing from unreviewed prompts.
