DeFi AMM Security

Critical vulnerability patterns and hardened implementations for Solidity AMM contracts, LP vaults, and swap functions.

When to Use

• Writing or auditing a Solidity AMM or liquidity-pool contract
• Implementing swap, deposit, withdraw, mint, or burn flows that hold token balances
• Reviewing any contract that uses token.balanceOf(address(this)) in share or reserve math
• Adding fee setters, pausers, oracle updates, or other admin functions to a DeFi protocol

How It Works

Use this as a checklist-plus-pattern library. Review every user entrypoint against the categories below and prefer the hardened examples over hand-rolled variants.

Execution Safety

The shell commands in this skill are local audit examples. Run them only in a trusted checkout or disposable sandbox, and do not splice untrusted contract names, paths, RPC URLs, private keys, or user-supplied flags into shell commands. Ask before installing tools or running long fuzzing/static-analysis jobs that may consume significant local or paid resources.
