USDest is the synthetic dollar of the USD.estate ecosystem. It is a highly liquid, 1:1 USD-pegged asset that serves as the base layer for the protocol.

USDest

USDest is the synthetic dollar of the USD.estate ecosystem. It is a highly liquid, 1:1 USD-pegged asset and the base layer of the protocol.

The wider protocol allocates to real-estate bonds, but USDest itself is a pure dollar instrument. It is built for composability across DeFi and gives a stable medium of exchange without the credit or duration risk of the yield-bearing vault.

Collateral & Backing

USDest is fully backed by USDC reserves. Part of the reserve is held in tokenized funds investing in short-dated US Treasury bills, and the rest is held as USDC to meet redemptions.

USDest has no exposure to real-estate bonds or any issuer. It is isolated from property values, issuer credit risk and bond liquidity. Those risks sit only in sUSDest.

Minting is restricted by code. USDest can enter circulation only when the equivalent USDC is deposited into the protocol. There is no private-key minting, and total supply can be verified onchain at all times.

Reserve component	Role	Liquidity
USDC	Redemption buffer for approved institutions	Immediate
Tokenized T-bill fund	Yield on reserves, harvested into sUSDest	Per the fund's dealing terms

Eligible reserve funds must offer at least daily dealing, so redemptions beyond the immediate USDC buffer settle on the fund's own dealing cycle — typically same-day or T+1 — rather than on a multi-day cycle. The fund's published dealing terms govern in every case. The USDC buffer keeps the reserve usable under redemption stress without touching the fund at all.

The share of the reserve held as USDC versus T-bills is a protocol parameter (USDC_BUFFER_BPS). See Governance & Parameters.

Where does the reserve yield go?

The T-bill yield earned on USDest reserves is not paid to USDest holders. The reserve is custodied by the BasePositionManager, not by the USDest contract. When the reserve's value rises above USDest supply, the BasePositionManager harvests the surplus and instructs USDest to mint it as new USDest into the sUSDest vault, net of an admin fee. That is why USDest stays at exactly one dollar while sUSDest earns T-bill yield on top of bond coupons.

Minting and Redemption

USD.estate uses an allowlisted market model for direct protocol interactions, starting at launch. Direct minting and redemption at the smart contract level are limited to:

Authorized Market Makers: KYC/KYB-verified partners who manage primary liquidity.
Institutional Depositors: large participants who have completed the USD.estate Foundation's compliance onboarding and signed the Institutional Mint & Redemption Agreement.

Why an allowlist?

Compliance: direct counterparty relationships give clear source-of-funds evidence for every dollar entering the reserve.

Security: restricting contract-level minting to verified entities removes the attack surface for "infinite mint" and similar exploits.

Market Access & Liquidity

USDest is a permissionless asset. Any wallet can hold, transfer, stake and unstake it without restriction, and secondary markets on DEXs and CEXs are open to all.

If you are not on the allowlist: buy USDest on a DEX or CEX, then stake it in the App to receive sUSDest and start earning.

Seed liquidity for a USDC/USDest pool will be provided at launch as part of the protocol's launch commitment, so a secondary market is available from day one.

Approved institutions that arbitrage the secondary price against 1:1 mint and redemption keep USDest trading close to one dollar.
