Universal Private Dollar

Private stablecoin powered by UPP

What is UPD?

Universal Private Dollar (UPD) is an on-chain overcollateralized stablecoin pegged to the US dollar, but with privacy built in.

UPD uses Universal Private Pools (UPP)to shield your balance and transactions from public view while remaining fully compliant.

Why Privacy Matters

On public blockchains, every transaction is visible to everyone. Your neighbors can see what you bought, your competitors can monitor your deals, and bad actors can target you based on your visible wealth.

Traditional banks don't broadcast your transactions to the public. UPD brings that same privacy to stablecoins—without sacrificing compliance.

Who Benefits

Protect Your Wealth

Wrench attack prevention

Problem: Visible on-chain balances make you a target for physical attacks or extortion

Solution: Shield your balance into private notes—observers can't see how much you hold

Confidential Payments

Medical, legal, sensitive services

Problem: Payments reveal the nature of services you receive—your health conditions, legal issues

Solution: Pay to stealth addresses—observers can't link your wallet to your service provider

B2B Confidential Deals

Protect business relationships

Problem: Competitors monitor public wallets to discover your suppliers, partners, and deal terms

Solution: Private transfers hide counterparties and amounts from prying eyes

How UPP Works

Private Addresses

Each user gets a stealth address—like a bank account number that provides privacy without hiding who you are from legitimate parties.

Know Your Counterparty

Sender and receiver know each other (like a bank transfer), but observers can't see who sent what to whom. Compliance-friendly by design.

Viewing Keys

Export transaction visibility on demand for tax or regulatory audits. You control disclosure—selective transparency, not surveillance.

No Middlemen

Pay your own gas—no relayers taking fees. Your funds are always yours with ragequit protection to exit anytime.

Three Simple Steps

1

Shield

Deposit tokens into the Universal Private Pool. Your deposit creates a private 'note' that only you can spend.

2

Transfer

Send tokens privately to any stealth address. The blockchain sees a valid transaction but not who sent what to whom.

3

Unshield

Withdraw tokens back to any Ethereum address when you're ready to use them publicly.

Built for Compliance

ASP verification confirms transaction origins
Viewing keys enable selective audit disclosure
Origin tracking ensures funds can return to source
Ragequit protection—you can always withdraw your funds
Demo Environment

TST (Test Token) is a simplified demo version of UPD.

TST uses a fixed 3000:1 ETH rate instead of real collateralization. Production UPD maintains its USD peg through overcollateralization mechanics.
