Lock DGB in a vault and get DigiDollars for it; burn them later to take every DGB back.

1. Cost: what a mint locks, for each lock time.
2. Gather: many small coins into one; a mint spends only a few. Press it again at once for the rest.
3. Mint: your wallet shows the transaction and signs it.
4. My vaults: each vault, and when it unlocks; Redeem appears once it has.
5. Receive and Send: your DigiDollar address (TD... on the test chain, DD... on mainnet), and paying someone's.

The same in the console: ddcollateral 100 0, ddgather, ddmint 100 0, ddvaults, ddredeem <vault>, ddreceive, ddsend <address> <dollars>. Each takes main or test last. Mainnet mints and sends are off on this arcade until its operator turns them on.
