Resupply · interactive mechanism simulation

Depositors lock crvUSD into a Curve Lend / Fraxlend vault, the yield-bearing share is pledged as collateral in Resupply's CDP, and reUSD is minted against it. A newly deployed, near-empty vault is a soft target: an attacker can donate assets directly into it to warp the share price and borrow reUSD against phantom collateral.

Illustrative simulation. Modeled on Resupply's March 2025 launch and the June 2025 exploit, where an attacker donated crvUSD into a freshly deployed, near-empty ERC-4626 lending vault to inflate its share price and borrowed ~$9.6-10M in reUSD against phantom collateral. "Vault seed protection" represents mitigations like virtual shares/minimum seed deposits — raise it and the same attack does far less damage. Not live onchain data.
