Digital Asset
Infrastructure.
A stable digital Euro for spending, and a Bitcoin-backed reward token for growing your wealth.
Built for Onyx tokenization workflows, including planned real-world asset platform initiatives.
Two Coins. One Powerful Ecosystem.
We separated "spending" from "growing" so you get the best of both worlds.
EUPY
The Digital Euro
A stable digital currency worth exactly €1.00. Use it to pay, save, or send money anywhere in the world – instantly and privately.
EUPX
Bitcoin-Linked Protocol Asset
A Bitcoin-linked protocol asset built around a 0.7x BTC reference profile, a 50% floating floor, and a 98/2 cbBTC plus USDC reserve model on Base.
Access both coins from one dashboard. Just connect your wallet.

Holding Bitcoin
Direct BTC market ownership
- ✗Pure BTC exposure with full market volatility
- ✗Requires separate custody, bridging, or exchange workflows
- ✗No Onyx issuer formula, reward model, or Base-native token workflow
- ✗Not automatically connected to EUPY settlement tools
EUPX Asset Token
BTC-linked protocol pricing
- ✓Base-native token designed for wallet and dashboard workflows
- ✓Issuer price is built from transparent floor and premium components
- ✓Chainlink-based BTC/EUR inputs support pricing logic
- ✓Virtual Mining rewards and status can be reviewed before taking action
The Math is Simple
Here's why Virtual Mining is like owning Bitcoin
EUPX never falls below half of BTC's price
Every EUPX is backed by actual Bitcoin
Bitcoin doesn't pay you – EUPX does
Real Example
If Bitcoin is worth $100,000 today:
Unlike Bitcoin, EUPX pays you to hold it. That's Virtual Mining.
