DeFi platforms lose millions annually to smart contract exploits, flash loan attacks, oracle manipulation, and private key compromise. This guide covers the major attack vectors threatening decentralized finance applications and outlines security best practices: writing secure Solidity code using audited libraries like OpenZeppelin, conducting independent smart contract audits, performing extensive testing (unit, fuzz, mainnet fork simulations), using multi-signature wallets for admin privileges, integrating decentralized oracle networks, implementing emergency circuit breakers, and maintaining security across the full development lifecycle from planning through post-launch monitoring.
