Overview

End-to-end security review of recurring trade automation across UI orchestration, API validation, and on-chain execution paths.

Scope

FrontendBackendSmart Contract

Stack: React / Node.js / Solidity / PostgreSQL

Method

AI-assisted detection

AI agents continuously mapped cross-surface call graphs, anomaly-clustered suspicious transitions, and prioritized suspicious edge paths for human review.

Auditor-owned decisions

Senior auditors validated exploit feasibility, reproduced high-impact paths, and set final severity with remediation guidance and recheck criteria.

  1. 01 Mapped trust boundaries across client, API, relayer, and contract surfaces.
  2. 02 Stress-tested authorization and replay controls under abnormal timing.
  3. 03 Validated remediation with targeted re-tests before final issuance.

Key Risks

  • Order parameter drift between UI preview and signed transaction payload.
  • Weak server-side replay constraints on delayed recurring triggers.
  • Insufficient fallback handling during provider/routing degradation events.

Outcome

All high and medium findings were remediated and independently verified before final clearance issuance.
