Solidity
Security
Contract programming language for EVM chains.
Solidity is a statically‑typed language used to write EVM smart contracts. It compiles to EVM bytecode and is supported by popular tooling like Foundry and Hardhat. Security reviews, tests, and audits are crucial due to immutable deployments and value at risk.
Frequently asked questions
How do I avoid common pitfalls?
Use latest compiler, enable optimizations, follow checks‑effects‑interactions, use OpenZeppelin libraries, and write invariant/property tests. Get independent reviews.What test tools should I start with?
Foundry (forge) or Hardhat for unit and fuzz tests, Echidna or Foundry invariants for property testing, Slither/Consensys tools for static analysis.When is upgradeability appropriate?
Only when governance and risk justify it. Use transparent/beacon proxies, document admin controls, and maintain rigorous upgrade procedures.
