한눈에 보기

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).

OpenZeppelin Security이란

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).

❓ 자주 묻는 질문

▶Why use OpenZeppelin instead of writing contracts from scratch?
OpenZeppelin contracts are audited (hundreds of thousands of lines analyzed by security firms). Writing from scratch = high risk of bugs (reentrancy, overflow, etc). Audited code = proven secure.
▶What's the difference between ERC-20 and ERC-721?
ERC-20 = fungible tokens (all tokens identical, 1 = 1). ERC-721 = NFTs (each token unique). ERC-20 like dollars, ERC-721 like rare paintings.
▶How do I upgrade a contract after deployment?
Proxy pattern. Deploy proxy pointing to implementation contract. Upgrade = deploy new implementation, proxy points to it. Users interact with same address, logic changes. OpenZeppelin handles this.
▶What's access control?
Defining who can call what. Example: only owner can mint tokens. OpenZeppelin AccessControl = role-based. User has role (admin, minter, etc), functions check role.
▶Can I integrate OpenZeppelin with other projects?
Yes. OpenZeppelin is library, import and extend. Used by 90% of DeFi protocols. Composable and modular.
