The Solana Development Course has dropped on Updraft. 12 programs. Native Rust + Anchor. Security CTFs. Completely free.

Your newest AI security engineer has just arrived. Cygent isn't just an AI bug scanner; it learns your codebase, works alongside your team, and writes the PRs to fix them. - Finds bugs - Gets on calls - Schedules tasks - Proactive security advice All in your chat interface 🧵

We are excited to be applying for the Ethereum Security QF round! giveth.io/project/cyfrin…

Learn formal verification, Assembly, Huff, and how they fit together in the Assembly and Formal Verification course on Updraft. Completely free. updraft.cyfrin.io/courses/formal…

The takeaway: formal verification doesn't replace auditing or testing. But it lets you make specific, provable guarantees about code equivalence that no amount of unit tests can match.

You can write readable Solidity, rewrite it in Assembly/Huff for gas optimization, then mathematically prove both versions behave identically. That's formal verification. And it's a legitimate superpower. 🧵

Learn Vyper smart contract development from scratch, completely free: updraft.cyfrin.io/courses/intro-…

Why this matters: the Vyper compiler checks your interface calls at compile time. If you pass the wrong type or forget a parameter, you get an error before you ever deploy. No silent failures on-chain.

Most Vyper developers learn to call other contracts using raw ABI encoding. There's a cleaner way built right into the language: in-line interfaces. 🧵

Learn Vyper development from scratch, including interfaces, factory patterns, and deployment with Moccasin: updraft.cyfrin.io/courses/interm…

Once imported, you use it exactly the same way: favorites_contract: i_favorites = i_favorites(self.list_of_favorite_contracts[favorites_index]) favorites_contract.store(new_number) Same functionality. Better organization.

Vyper has two ways to define interfaces. One of them keeps your contracts way cleaner than the other. 🧵
