Voucher

The process is the same as with mint PID. After purchase, go to the 'My Portfolio' page to view the list of my vouchers and check the details of the voucher.

Bid voucher

When a voucher is minted by someone else and the voucher has not been redeemed yet, other users can make bidding transactions for this voucher. They provide offers to the voucher owner. The offer price is an integer and the deadline is within 30 days.

Accept/refuse offer

When a voucher holder receives an offer, they can accept or reject the offer in 'My Voucher' or notifications. If an offer expires, it will not appear in the 'My Offers' list. When accepting an offer, the system verifies if the bidder's wallet balance is greater than the offered amount; if not, the voucher holder cannot accept the offer.

Modify offer

The offer initiator can cancel or modify the offer's details before it is rejected or accepted. This includes modifying the offer amount and deadline.

Voucher redeem

When purchasing a voucher or obtaining a voucher through an offer, users can redeem the voucher into PID. After redemption, the user gains all privileges, equivalent to those who directly purchased PID. If a user has already purchased PID, they cannot redeem the voucher.
