How miners and validators can manipulate block timestamps to exploit time-dependent smart contract logic. Learn about timestamp dependence, randomness, and secure alternatives.
From approval frontrunning to fee-on-transfer bugs and rebasing tokens — the ERC-20 pitfalls that break DeFi integrations and lose user funds.
How mismatched storage layouts between proxy and implementation contracts lead to corrupted state, unauthorized access, and fund theft. Learn safe storage patterns.
Why on-chain randomness is fundamentally broken and how to use Chainlink VRF, commit-reveal, and other patterns to get verifiable randomness in your smart contracts.
Security risks specific to NFT smart contracts — from reentrancy via onERC721Received to mint manipulation, metadata attacks, and royalty bypass.
A deep dive into reentrancy guard implementations — OpenZeppelin's ReentrancyGuard, custom guards, transient storage in EIP-1153, and when guards aren't enough.
A practical guide to upgrade patterns — Transparent Proxy, UUPS, Diamond (EIP-2535), and Beacon proxies. When to use each and how to avoid upgrade-specific vulnerabilities.
How to build more secure cross-chain bridges — validator architecture, message verification, rate limiting, emergency controls, and lessons from $2B+ in bridge exploits.
