How upgradeable proxy patterns create security risks — storage collisions, uninitialized proxies, and selfdestruct attacks. Learn to implement safe upgrade patterns.
How gas-based attacks can freeze smart contracts, block withdrawals, and halt protocol operations. Learn about unbounded loops, block gas limits, and griefing protection.
Why ignoring return values from external calls and token transfers leads to silent failures and fund losses. Learn the safe patterns for handling call results in Solidity.
As protocols expand across chains, new attack surfaces emerge. Learn about message verification, replay attacks, liquidity fragmentation, and cross-chain composability risks.
How miners and validators can manipulate block timestamps to exploit time-dependent smart contract logic. Learn about timestamp dependence, randomness, and secure alternatives.
Beyond standard vulnerability categories — how flawed economic assumptions, accounting errors, and edge-case bugs in DeFi protocol logic lead to catastrophic losses.
A comprehensive checklist for auditing smart contracts — covering access control, business logic, external integrations, gas optimization, and deployment security across Solidity and Rust.
Security best practices for Solana programs — covering account validation, PDA security, CPI risks, signer verification, and common Anchor framework pitfalls.
From approval frontrunning to fee-on-transfer bugs and rebasing tokens — the ERC-20 pitfalls that break DeFi integrations and lose user funds.
