New Video! Echidna is still one of the most underrated tools in smart contract security. Even with Foundry, it does things fuzzing alone won’t catch. We show how to set it up, use snapshots and invariants, and test real DeFi contracts. Thanks @zokyo_io for another important…
Gn 😴 Real talk: Most "audited" projects are one vulnerability away from a rug. True alpha isn't just about the next gem, it's about knowing which ones are actually built to last. That's why top builders & degens alike respect @zokyo_io founded by @hartejsengh They're the…
