Smart Contract Testing
Traditional unit tests check scenarios you think of. Fuzz testing and invariant testing find the scenarios you didn't think of — and in smart contracts, those are often the $10M bugs. Foundry's fuzzer has become the industry standard for property-based testing of Solidity contracts. This guide
Smart Contract Testing
Most Web3 testing guides cover smart contract unit tests or frontend component tests in isolation. But users experience your dApp end-to-end: they connect a wallet, click a button, wait for a transaction, and see the updated state. If any part of that chain breaks, they lose money or
Smart Contract Testing
Cross-chain bridges have been the most catastrophically exploited category of smart contracts. Ronin Bridge ($625M), Wormhole ($320M), Nomad ($190M), Harmony Horizon ($100M) — a combined $2+ billion drained in 18 months. The bugs differ, but the pattern is consistent: insufficient validation of messages crossing chain boundaries. This guide covers how
