4年打磨-2022年海外一线大厂-以太坊开发教程（a solidity tutorial makes you a dapp expert）WIP
A Chinese-language EVM full-stack tutorial covering Solidity basics through DeFi protocol internals, maintained by a Singapore-based developer who started in blockchain in 2017. The scope is broad: syntax, advanced Solidity patterns, major EIPs, contract attack patterns with real PoCs, and both Hardhat and Foundry toolchains. It is a study guide, not a library.
The security section is the strongest part — it walks through 14+ real attack classes (reentrancy, delegatecall, signature replay, tx.origin, encodePacked collision) with concrete code, not just theory. The EIP coverage goes beyond the usual ERC20/721 trio and includes ERC4626, EIP712, permit, and permit2, which most tutorials skip. Adding Foundry alongside Hardhat is the right call; most tutorials from this era were Hardhat-only and that content aged poorly. The DeFiHackLabs exploit collection bundled in the security chapter gives learners runnable Foundry forks of real incidents.
The entire tutorial is in Chinese — the English description and repo title oversell its accessibility to non-Chinese readers. The 'solana' topic tag is wrong; this is EVM-only content and that tag will mislead people. The DeFiHackLabs section is a vendored copy of an external repo, not original material, so you're getting a frozen snapshot of someone else's work without their updates. The WIP label is honest but the practical effect is that some protocol chapters (Uniswap, Compound, AAVE) are referenced but the depth varies — a learner following the outline will hit dead ends.
