Bridges & Cross-Chain

Bridges are high-value targets—over 50% of DeFi losses come from bridge exploits. Cross-chain verification requires specialized monitoring.

Key Risks

• Message validation failures between source and destination chains

• Mint/burn mismatches creating unbacked tokens

• Relay manipulation submitting fraudulent cross-chain messages

• Upgrade vulnerabilities in bridge contracts

Guards We Deploy

Cross-Chain Message Matching — Verify bridged amounts match between source and destination.

Mint/Burn Limits — Alert when token minting exceeds expected thresholds.

Bridge Relay Monitoring — Track relay operations and flag anomalies.

Upgrade Event Guards — Monitor proxy upgrades and initialization calls.
