transferInterface with { owner } transfers tokens from an associated token account as an approved delegate. The delegate is the transaction authority. Only the delegate and fee payer sign; the owner’s signature is not required.
  • The recipient is a wallet address (associated token account derived and created internally)
  • The amount must be within the approved allowance
  • Each transfer reduces the remaining allowance
