DigiDollar glossary
Vault
A position you open by locking DGB as collateral. It's yours alone — no company or admin key controls it. A vault tracks how much DGB is locked, the collateral ratio you chose, and how many DigiDollars have been minted against it.
Collateral ratio
How much collateral value you lock relative to what you mint, e.g. 300% means locking $300 of DGB to mint $100 of DigiDollars. Higher ratios cushion against DGB price drops but tie up more DGB; DigiDollar's published range is 200%–500%.
Oracle
A service that feeds the real-world DGB/USD price on-chain so the protocol knows what your locked collateral is worth. DigiDollar is designed to use multiple independent oracle operators reaching consensus, rather than trusting one source.
Lock period
The fixed length of time (30 days to 10 years) your collateral stays committed once you mint. Instead of liquidating vaults when DGB's price drops, DigiDollar holds the lock — you get your DGB back at the end of the period rather than risking a forced sale mid-lock.
Mint / burn
Mint is creating new DigiDollars by locking DGB collateral into a vault. Burn is the reverse — returning DigiDollars to redeem your locked DGB, which removes those DigiDollars from circulation.
