The Ethereum Object Format (EOF) proposal removes dynamic jumps to make smart contract bytecode more predictable and analyzable. Some critics argue that easier static analysis offers limited value, but we disagree. Static analysis tools have already prevented countless costly bugs. Simplifying EVM control flow could pave the way for safer contracts and better tooling. Security must be a central factor when shaping Ethereum’s future.

Formal Verification
Formal verification is the only tech that proves your code works as intended, across all inputs. As bugs continue to drain millions from Web3 apps, formal methods offer strong, mathematical guarantees. Learn why DeFi and critical smart contracts can't afford to skip it anymore.

Product & Company
Certora has open-sourced the Certora Prover, the most advanced formal verification tool for smart contracts on Ethereum, Solana, and Stellar. Used to secure over $75B in DeFi assets, the Prover guarantees correctness by detecting all potential bugs. Start verifying your code today!

Operational Security
The Bybit breach targeted its Ethereum (ETH) multisig cold wallet—a storage system touted as ultra-secure. This wasn’t a brute-force attack or a flaw in the blockchain itself; instead, it was a sophisticated operation that exploited human trust and operational weaknesses. For anyone using or considering a multisig wallet—whether you’re a crypto enthusiast, a startup founder, or a business managing digital assets—this incident is a wake-up call. Let’s break down what happened and what you can do to keep your funds safe.

Operational Security
Safeguard is a Geth extension that monitors Ethereum protocol invariants in real time to enhance the security of DeFi systems and monitor exploits.
