About

The official Solidity documentation covers the language spec, getting-started tutorials and security recommendations, with a community-maintained Chinese translation — the base reference for contract development.

Read the security section before writing code and you will dodge most common pitfalls. The Chinese translation lags slightly — treat the English version as current.
