✍️ Formal Verification: Securing Vaults with Certora Prover
In our latest blog post, our security ninjas show how Certora Prover can verify an ERC-4626 vault implementation.
Highlights:
- Safely handle ERC20 arithmetic to avoid havoc-induced overflows
- Use ghost variables and hooks to track balances on a deeper level
- Enforce invariants like totalSupply == sumOfBalances
- Catch malicious changes early on (ex: free extra shares for the vault owner)
Check out the full breakdown and see how we used Foundry + Certora to keep vault logic airtight:
