Compressed PDA Programs
Build Solana programs with compressed accounts via CPI to the Light System Program. No rent-exemption required.
| Creation cost | Solana account | Compressed account |
|---|---|---|
| PDA (128 bytes) | ~1,100,000 lamports | ~5,000 lamports |
When to use compressed PDAs
- Per-user state (profiles, game state, credentials)
- DePIN device registrations
- Nullifier-based double-spend prevention
- Infrequently accessed accounts
