Solidity projects often fail security reviews not because of one obvious bug, but due to common implementation mistakes that enable loss of funds, privilege escalation, replay attacks, or oracle/MEV exploitation.
Use this security guide to audit a Solidity contract you plan to deploy, then verify that each checklist item (especially reentrancy, oracle safety, approvals, access control, and upgrade/storage safety) is explicitly satisfied.

A pre-deploy audit checklist for Solidity smart contracts codifies high-impact defensive patterns, verifying reentrancy protections, oracle safety, access control, and correct numeric handling before mainnet deployment to prevent loss of funds.
To prevent reentrancy and MEV exploitation in Solidity, enforce Checks-Effects-Interactions (CEI) patterns, apply reentrancy guards, and implement explicit MEV mitigation and oracle safety controls before contract deployment.
Secure ERC20 token interactions and proxy upgrades by using SafeERC20 for token quirks, enforcing bounded approvals, applying strict input validation, and verifying upgrade and storage safety for proxy patterns.
You need SafeERC20 and strict input validation in smart contracts interacting with ERC20 tokens, signing schemes, or external dependencies like oracles and DEX swaps to prevent decimals mistakes and privilege escalation.
Yes, this deployment-grade security checklist helps teams run consistent static analysis, fuzzing, and verification steps, ensuring critical edge cases and defensive patterns are explicitly satisfied before going live.
Common Solidity security vulnerabilities include decimals mistakes, unsafe math, reentrancy, MEV sandwich issues, oracle exploitation, replay attacks, and access control failures that enable loss of funds.
