Pre Authorized Debit

CI Status

SDK Code Coverage

The Pre Authorized Debit (PAD) program is a Solana primitive to extend functionality of a token account with pre-authorized debits (an advanced form of multi delegation or delegate multiplexing which we call smart delegation). The PAD program supports both spl token program and token program 22.

User funds remain non-custodial in their own token accounts, adding a smart-delegate account as their delegate.

Users and protocols agree on and create a pre-authorization account to track the pre-authorized debit state. Pre-authorized debits can be one-time or recurring.

Pre-authorized debt authorities can debit from a users token account using their pre-authorization and the smart-delegate. Debt authorities can debit from a token account as long as:

• The pre-authorized debit is ready for debiting
• The token account has the necessary funds needed for the debit
• The smart-delegate remains the delegate of the token-account

Users at any time withdraw from their token-account as the owner or pause a pre-authorized debit.

Planned Future Work

To prevent accidental removals of the token-account delegate, an ancillary program is planned for future development, mimicking a similar feature set as the associated token program.
