BEYOND STANDARD SECURITY
Why a Specialized Remittance Audit is Critical
Cross-border payment smart contracts handle high-value, regulated transactions. A generic audit misses the unique financial, compliance, and operational risks inherent to remittance systems. Our specialized approach ensures your protocol is secure, compliant, and operationally resilient.
03
Fee Structure & Slippage Analysis
Review of dynamic fee models, liquidity provider incentives, and slippage calculations. Ensures economic fairness and prevents exploits that could drain treasury or user funds during large transfers.
04
Operational Resilience & Pauses
Assessment of admin functions, upgrade mechanisms, and emergency pause logic. Verifies secure multi-sig controls and fallback procedures to protect funds during incidents without creating centralization risks.
05
Compliance Event Logging
Audit of immutable on-chain logging for transaction provenance, sender/receiver addresses, and amounts. Ensures data integrity for mandatory regulatory reporting and forensic analysis.
06
Integration Security
Examines secure integration points with traditional payment rails (bank APIs, card processors) and other DeFi protocols. Focuses on API key management and data validation at the contract boundary.
