Quasar — Zero-Copy Solana Program Framework
Quasar is a no_std Solana program framework. Accounts are pointer-cast directly from the SVM input buffer — no deserialization, no heap allocation, no copies. The syntax resembles Anchor but the types and patterns are completely different. Never use Anchor types.
Reference Files — Read Before Coding
Before writing code for any non-trivial feature, read the relevant reference file:
| Topic | When to read |
|---|---|
references/accounts.md |
Account types, constraints, dynamic fields (String, Vec), sysvars, remaining accounts |
references/tokens.md |
quasar-spl, SPL token CPI, Token-2022, ATAs, mint/burn/approve |
references/testing.md |
QuasarSvm full API, test patterns, chaining, error matching |
references/solana-model.md |
Solana account model, PDAs, rent, CPI mechanics — read this when building anything new |
If you're unsure which reference applies, read solana-model.md first, then the others.
