Always use checked math operations. Anchor provides these by default but native programs need to be careful.

One overflow bug can drain your entire protocol.

Account validation is crucial. Always verify:
1. Account ownership
2. Account discriminator
3. Expected seeds for PDAs

Never trust user-provided accounts blindly.

Trust but verify

Get an audit before launching with real money. The cost of an audit is nothing compared to the cost of a hack.

Many auditors offer discounts for smaller projects.

Use the Solana security.txt standard. It helps white hat hackers contact you if they find vulnerabilities.

Bug bounty programs are also worth setting up.
