# Vouchers

Vouchers are rewards from the Blue Wheel Gacha spins or other gifts from in-game rewards. Each one holds a stack of a single game material such as a resource, ore, processed material, or vial.

## Transfer and redeem

A voucher is an NFT. While it stays a voucher you can transfer or trade it.

To use it, redeem it from the Events page under Redeem. Redeeming burns the voucher and adds its materials to your town.

Once redeemed, the materials are spendable in-game only. They are used for crafting and repairs, and cannot be sold or transferred.

## Spending

Crafting and repair costs are paid from your redeemed voucher materials first, then from your regular stock.
