$DUC Vault
Earn, stake, and claim $DUC rewards generated by your card processing volume.
Your card volume should work for you, not just your processor. The $DUC Vault converts a slice of your processing volume into $DUC rewards you can stake, earn yield on, and claim on-chain.
Rewards are calculated automatically from your card volume, with a configurable claim threshold and staking terms including lockup and APY. A referral bonus engine rewards you for bringing new merchants into the network. It's a loyalty program where the merchant — not just the processor — gets paid.
What you get
- Rewards calculated on processing volume
- Staking with configurable lockup & APY
- Referral bonus engine for merchants
- Claim threshold and on-chain transfers
