Security audits, smart contract development, and Web3 engineering insights from Secudity.
Every pending Ethereum transaction sits in a public mempool before it's confirmed — and that visibility is a weapon. Learn how MEV bots front-run and sandwich DeFi trades, and the concrete techniques that protect your users and your protocol.
Oracle manipulation is behind some of the largest DeFi hacks in history. Learn how attackers distort on-chain price feeds using flash loans and low-liquidity pools, and the concrete patterns that keep your protocol safe.
Building secure smart contracts requires more than writing functional code. Discover the essential security best practices every Solidity developer and Web3 team should follow before deploying to mainnet.
Learn how fuzz testing in Foundry helps uncover edge cases, unexpected behaviors, and security vulnerabilities in Solidity smart contracts before they reach production.
Launching a smart contract? Use this comprehensive 20-point audit checklist to identify common security risks and improve your Solidity code before deploying to mainnet.
Understand one of the most dangerous smart contract vulnerabilities. Learn how reentrancy attacks work, see vulnerable Solidity code, and discover proven techniques to secure your contracts.
Learn about the 10 most common smart contract vulnerabilities, how attackers exploit them, and the best practices to protect your Solidity contracts.
