What is DigiDollar?
DigiDollar ($DD) is a decentralized US-dollar stablecoin built directly into the DigiByte blockchain. You create it by locking your own DGB as collateral — there is no bank, no company, and you keep control of your private keys the entire time.

The short version
DigiDollar lets you draw stable, dollar-denominated spending power from DGB you already hold — without selling it, and without handing your coins to anyone. You lock DGB, mint $DD, spend or hold it, and later return the $DD to release your DGB. You're borrowing against your own coins, not selling them.
Unlike stablecoins backed by a company's bank account, DigiDollar has no issuer to trust. It's enforced by DigiByte's own transaction rules — a stablecoin native to the chain, not a smart contract, a bridge, or an ERC-20 token layered on top.
How it works
Four steps, all happening inside DigiByte Core:
Lock your DGB
You commit DGB into a time-locked output in your own wallet. It's locked, not sent — it stays under your keys the whole time.
Mint DigiDollar
Based on the value of the DGB you locked and the current DGB/USD price, the protocol mints $DD to you. Each one is worth a dollar.
Use it
Send, receive, or hold $DD like any DigiByte transaction — but with a steady dollar value instead of a floating one.
Redeem
When your lock period ends, burn the $DD to release your collateral. Your DGB unlocks in full and returns to you.
What makes it different
- Genuinely decentralized. No issuer, no custodian, no bank behind it — it lives in the DigiByte protocol itself.
- Self-custody throughout. Your DGB never leaves your wallet. You hold your own keys from start to finish.
- No forced liquidations. Because collateral is time-locked, positions are never margin-called. They ride out the term.
- Native to a UTXO chain. Built into DigiByte's transaction rules using Taproot outputs — not layered on via contracts.
Collateral & lock periods
DigiDollar is over-collateralized: you always lock more DGB than the dollars you mint. How much more depends on how long you lock — shorter locks require more collateral, longer locks require less. There are ten tiers, from one hour to ten years.
| Lock period | Collateral | DGB per $100 |
|---|---|---|
| 1 hour | 1000% | 1,000 DGB |
| 30 days | 500% | 500 DGB |
| 1 year | 300% | 300 DGB |
| 5 years | 225% | 225 DGB |
| 10 years | 200% | 200 DGB |
A representative selection of the ten tiers. Longer locks need less collateral per dollar. Try the mint calculator for exact figures at any amount, or the position planner to map out a lock.
How the price stays near a dollar
DigiDollar reads the DGB/USD price from a decentralized oracle network — up to 35 independent oracle slots that draw from major exchange feeds. A quorum of seven signs each price bundle onto the chain using MuSig2 aggregate signatures, so no single oracle sets the price. You can watch the feed live on Oracle Watch.
What keeps the system stable
With no liquidations to fall back on, DigiDollar relies on layered safeguards instead:
- Over-collateralization. Every position starts with a buffer against DGB price drops — larger for short locks.
- Dynamic adjustment. Collateral requirements tighten automatically if overall system health falls.
- Emergency redemption. Under stress, redeeming can require burning a little more $DD — but you always get 100% of your collateral back.
- Volatility freezes. Minting can pause during extreme price moves to protect the system, then resume.
DigiDollar is liquidity against your own locked DGB — not free money. The debt is fixed in US dollars, and time-locks have no early exit: once you lock, that DGB is committed for the full term. Decide carefully. Nothing here is financial advice.
