Address Lookup Tables (ALTs) reduce transaction size by allowing addresses to be referenced by index rather than including full 32-byte public keys. This is especially useful for complex vault operations like pricing with many assets or DeFi positions.

When to Use ALTs

ALTs are recommended when:
  • The vault holds many assets that need pricing in a single transaction
  • DeFi integrations (Drift, Kamino) add many accounts to transactions
  • Transactions exceed the Solana transaction size limit (1232 bytes)
Pricing transactions are the most common case where ALTs are needed, as they reference oracle accounts, token accounts, and market accounts for each asset in the vault.
