Solana Program Security Checklist: 14 Critical Checks Before You Deploy to Mainnet

Solana Program Security Checklist: 14 Critical Checks Before You Deploy to Mainnet A battle-tested checklist distilled from $500M+ in Solana exploits — from missing signer checks to PDA seed collisions, with Anchor and native Rust code examples for every fix. Why Another Solana Security Checklist? Between Wormhole's $325M signer validation failure, Mango Markets' $115M oracle manipulation, and a steady stream of smaller exploits draining Solana DeFi protocols throughout 2025, one pattern is painfully clear: most Solana exploits are caused by a handful of recurring mistakes . The Solana programming model is fundamentally different from EVM. Accounts are passed in by callers. Programs are stateless. There's no msg.sender equivalent baked into the runtime. Every validation must be explicit, and every missing check is a potential exploit vector. This checklist isn't theoretical. Each item maps to a real exploit or a pattern we've seen fail in production audits. Use it before every mainnet
