🔐Security & Best Practices

Security and reliability references every Solana builder should review before shipping.

If you only read one section before shipping something public, read this one.

Essential Reading

• Program Security

• Verified Builds

• Anchor Verifiable Builds

• Fees

• PDA Accounts

• CPIs with PDA signers

Practical Advice

• do not treat a hackathon submission as an excuse to ignore security basics

• use the simplest possible architecture that still solves the problem

• understand signer checks, account ownership, and PDA behavior before mainnet thinking

• verify that your deployed code matches your source if the project continues after the hackathon

For Teams

Before submitting:

• confirm judges can access your repo and any docs

• document what is onchain and what is offchain

• explain why you chose Solana-specific design decisions
