TL;DR: yevm — (Yield-aware | Yet another) EVM implementation — async-first, WASM-native Ethereum VM in Rust, ~12.7K lines across 8 crates. 99.6% on GeneralStateTests at Cancun, cross-validated against revm on Osaka/Fusaka mainnet. Three application layers on top: in-browser simulation, yevm-lens...

TL/DR: reentrancy.rs — a classic reentrancy attack simulated end-to-end inside solenoid, running real Solidity contracts in-process completely locally. 8 ETH drained, full execution trace, no testnet required. Most reentrancy writeups show you the vulnerable contract and say “trust me, this is...

I built a small full-stack system for deterministic deposit addresses and automated treasury routing on Sepolia. The core idea is simple: each user gets a deterministic proxy address (CREATE2), the app monitors those addresses for incoming ETH, once funded, the system routes value to a...
