OpenZeppelin Security
OpenZeppelin is the standard library for Ethereum and EVM smart contracts. Provides battle-tested contracts (ERC-20, ERC-721, access control, upgradeable proxies). Avoids common vulnerabilities (reentrancy, overflow, access control bugs). Learning curve: 4-6 weeks for Solidity basics, 8+ weeks for production security. Salary: senior smart contract developers earn $200k-350k+. High scarcity: 500-1k expert Solidity engineers globally managing billions in TVL (total value locked).
什么是 OpenZeppelin Security
OpenZeppelin is a library of smart contract implementations for Ethereum and EVM blockchains. Provides battle-tested contracts for common use cases: tokens (ERC-20, ERC-721, ERC-1155), access control, upgradeable proxies, timelock, math utilities. Developers import and extend, avoiding reinvention of secure primitives. Code is audited, tested, and documented. Used by 90% of DeFi protocols ($500B+ TVL).
