In this post, we’ll show you how to test your smart contracts with the Echidna fuzzer. In particular, you’ll see how to: Find a bug we discovered during the Set Protocol audit using a variation of differential fuzzing, and Specify and check useful properties for your own smart contract libraries. And we’ll demonstrate how to do all of this using cryt

The initial release of yVault contained logic for computing the price of yUSDC that could be manipulated by an attacker to drain most (if not all) of the pool’s assets.
