Introducing UPD — A Stablecoin Without an Issuer

Every major stablecoin in circulation today has a central issuer. Circle issues USDC. Tether issues USDT. That issuer holds reserves in a bank, is subject to regulation, and — crucially — can freeze your balance.

UPD is different. There is no issuer.

The Protocol Is Your Counterparty

When you mint UPD, you deposit stETH into a smart contract. The contract calculates how much UPD to issue based on the current oracle price and mints it directly to you. No KYB. No approval process. No relationship with Permissionless Technologies required.

The same works in reverse: burn UPD, receive proportional stETH. The contract is the counterparty in both directions.

This matters because an issuer can be compelled. A smart contract cannot.

What "Private" Actually Means

The "Private" in Universal Private Dollar is not about transaction privacy — plain ERC20 transfers are fully visible on-chain. It refers to the absence of a central intermediary. Your funds are private from interference by any centralized entity.

For transaction-level privacy, UPD integrates natively with the Universal Private Pool (UPP), where transfers use ZK proofs. But that's opt-in and separate from UPD itself.

Built on stETH

The collateral backing UPD is stETH — Lido's liquid staking token. This means:

• Collateral earns yield passively (stETH rebases)
• Reserves are fully on-chain and verifiable by anyone at any time
• No bank accounts, no auditor attestations, no counterparty risk in TradFi

As the collateralization ratio grows with stETH yield, the system becomes safer over time without anyone needing to do anything.

What's Next

UPD is currently in tech preview on Sepolia testnet. The SDK is available now for integrators who want to start building. Mainnet deployment and security audits are planned before any real-value use.

We'll be sharing more about the StabilizerNFT system, how yield accrues as sUPD, and our post-quantum approach to privacy in future posts.
