Some thoughts on dispenser upgrades…

- **Delayed closing**  
Rather than closing the dispenser immediately, all dispenser closing are delayed by 5-10 blocks to prevent a dispenser operator from closing a dispenser with a high fee after buyer sends funds.

- **Close to creation address option**  
One pain point with dispensers is after they’re closed you need to send BTC to the dispenser address to be able to send the asset back to yourself. Adding a flag to send the dispenser escrow back to the creation address would alleviate this issue.

- **Allowable address option**  
Dispenser will only dispense to a pre-determined address when using this option. This would be the equivalent of leveraging Counterparty as the escrow for an OTC deal in BTC.

- **Expiration option**  
Similar to DEX orders, an expiration option would be specified as a number of blocks from creation. This could be used in conjunction with the “close to creation address” option to give users an Opensea-style experience.
