How extensions work with Light Token

  1. Create a Token-2022 mint with one or more extensions
  2. Register an interface PDA to hold balances from that mint in Light Token accounts
  3. Use the same Light Token APIs (transferInterface, wrap, unwrap) as any other token
Each extension adds specific state that’s generally initialized during mint or token account creation. When initializing either account, you can enable specific extensions simultaneously for different functionality. Most extensions can’t be added after an account is initialized. Use the Solana documentation to learn more about Token 2022 extensions.
