Review a cryptocurrency wallet’s token approvals, contract interactions, and transaction patterns. The skill produces a risk score, flags concerning activity, and prioritizes approvals for review in a security report.
Audit wallet security by analyzing token approvals, permissions, and transaction patterns. Use when checking wallet security, reviewing approvals, or assessing risk exposure. Trigger with phrases like "audit wallet", "check approvals", "security scan", or "revoke tokens".

Security analysis tool for cryptocurrency wallets. Scans ERC20 token approvals, analyzes transaction patterns, calculates security risk scores, and provides actionable recommendations to improve wallet security.
Important: This is a read-only analysis tool. It does NOT execute transactions, manage private keys, or perform revocations.
Before using this skill, ensure you have:
requests library installedETHERSCAN_API_KEY environment variable for higher rate limitsScan wallet for all active ERC20 token approvals:
cd ${CLAUDE_SKILL_DIR}/scripts
python wallet_auditor.py approvals <address> --chain <chain>
Options:
--chain: ethereum, bsc, polygon, arbitrum, optimism, base (default: ethereum)--unlimited: Show only unlimited approvals--verbose: Detailed outputComprehensive security analysis including approvals, transaction history, and patterns:
python wallet_auditor.py scan <address> --verbose
Analyzes: 4. Active token approvals (unlimited, risky) 5. Transaction history patterns 6. Contract interactions (verified vs unverified) 7. Suspicious activity detection
Get weighted security risk score (0-100, higher = safer):
python wallet_auditor.py score <address>
python wallet_auditor.py score <address> --json # JSON output
Score components: 8. Approvals (40%): Unlimited, risky, stale approvals 9. Interactions (30%): Contract verification, flagged addresses 10. Patterns (20%): Transaction frequency, diversity 11. Age (10%): Wallet maturity
Risk levels: 12. 90-100: SAFE 13. 70-89: LOW 14. 50-69: MEDIUM 15. 30-49: HIGH 16. 0-29: CRITICAL
Review recent contract interactions and patterns:
python wallet_auditor.py history <address> --days 30
Detects: 17. Rapid approval patterns 18. Interaction bursts (many contracts in short time) 19. High failure rates 20. Dust attacks
Get prioritized list of approvals to revoke:
python wallet_auditor.py revoke-list <address>
Flags: 21. Unlimited approvals to unknown contracts 22. Risky/flagged spenders 23. Stale approvals (>6 months)
Create comprehensive security audit report:
python wallet_auditor.py report <address> --output report.txt
python wallet_auditor.py report <address> --json # JSON format

| Error | Cause | Solution |
|---|---|---|
| Address validation failed | Invalid format | Use 0x + 40 hex characters |
| RPC timeout | Node unresponsive | Retry or use different RPC |
| Rate limited | Too many requests | Add ETHERSCAN_API_KEY |
| No approvals found | Wallet clean | Normal - no action needed |

Add a synthetic-data CI gate for customer-owned Abridge integration code. Test consent handling, note-review handoffs, redaction, and rollback behavior with mocked vendor boundaries, without connecting CI to a live Abridge or EHR tenant.
Triage Abridge recording, note review, Epic handoff, and access problems using observed symptoms and approved guidance. Identify the affected workflow stage, organize a minimal timeline, and prepare a redacted escalation record for the responsible team.
Map and review an Abridge clinical documentation workflow from consent and recording through draft review, evidence checks, edits, and final disposition. Keep clinician approval explicit, identify failure exits, and separate verified facts from tenant-specific details and pending approvals.
Audit how clinician-reviewed Abridge note sections map into Epic templates and downstream workflows. Use approved test records to document destinations, exceptions, evidence, rollback steps, and a go or no-go decision for a specific environment.
Review Abridge adoption and workflow value using local usage records, clinician feedback, and verified contract costs. Build an evidence based decision table covering adoption, quality, support burden, and options to expand, hold, or improve the rollout.
Prepare a bounded support bundle for an Abridge issue using allowlisted operational details such as versions, coarse timestamps, and correlation references. Exclude recordings, transcripts, patient identifiers, credentials, and unrestricted logs, then document redactions and review details.
