dHEDGE vaults implement contract whitelisting to protect against front-end attacks

Following the CoWSwap incident, dHEDGE highlighted its security approach:

  • Vaults only execute transactions to pre-approved, whitelisted contracts
  • Protection works regardless of which front-end interface users access
  • Malicious contracts are automatically rejected at the smart contract level

This comes as on-chain attacks continue to exploit vulnerabilities.​ Recent incidents include:

  • DRLVaultV3 attack on Ethereum (~$100K USDC) due to missing slippage protection
  • RWB flash loan exploit on BSC (~$180K) using price manipulation

Forta Firewall flagged both exploits in real-time.​ Security basics remain critical: use slippage protection, verify contracts, and implement pre-execution screening.​

Key takeaway: Contract-level whitelisting adds a crucial security layer that protects users even if a front-end is compromised.​
