Program Derived Addresses

PDAs

Program Derived Addresses (PDAs) are deterministic addresses derived from seeds and a program ID.

Key Properties

• Deterministic — Same seeds always produce the same address
• Off-curve — Not valid Ed25519 public keys (no private key exists)
• Signable by programs — The program can sign on behalf of the PDA
