SDUSD, issued by the dTRINITY Protocol smart contracts under the governance of prospective TRIN tokenholders, is a tokenized yield-bearing vault interest that represents staked dUSD deposited into the dLEND lending market and accrues value over time. [S1][S2]

Each SDUSD token represents a claim on dUSD staked through the dSTAKE ERC-4626 vault, whose underlying backing consists of over-collateralized dUSD loans held within the dLEND lending market. [S1][S2] Holders receive a total-return accrual as the SDUSD to dUSD exchange rate increases over time, driven by lending yield from dLEND, rather than a rebasing balance. [S1][S2] Unstaking SDUSD back to dUSD may incur a fee of up to 0.1%, retained by the vault for the benefit of remaining holders. [S2]

The interfaces and documentation are operated by Trinity Foundation Ltd., a Singapore-based non-profit public company limited by guarantee, which states it does not control or operate the protocol; the asset is not issued by a single corporate entity but minted permissionlessly via smart contracts. [S3] The Terms of Use are governed by the laws of the Cayman Islands, and tokens are held non-custodially in users' wallets. [S3] Users must be at least 18 and not resident in any Restricted Region, including Singapore, the United Kingdom, the United States, and Russia. [S4] Holders unstake by depositing SDUSD to receive dUSD, with capacity set by available dUSD liquidity in dLEND. [S2]

SDUSD is an ERC-4626 vault token. [S1] The full protocol is native to Fraxtal, the genesis network since the fourth quarter of 2024, with native deployment on Ethereum mainnet from the first quarter of 2026; reserves and collateral are chain-isolated and not fungible across networks. [S5] Value accrues onchain via an increasing SDUSD to dUSD exchange rate, with settlement effectively immediate per transaction. [S1][S5]

Tokenized funds

dUSD is minted by depositing supported collateral stablecoins into the dTRINITY protocol; redemption is 1:1 against reserves. The reserve yield mechanism rebates borrowing interest on dLEND for DUSD borrowers, creating a unique cost-reduction loop versus typical stablecoin yield distribution.

dTRINITY issues dUSD (DUSD) and its staked variant sdUSD across multiple chains (Ethereum, Fraxtal, Katana, Ronin). DUSD is 1:1 USD-pegged and backed by an on-chain reserve of USDC, FRAX, DAI, sFRAX, and sDAI. Reserve yield is used to subsidise borrowing costs on the dLEND lending market rather than distributed to token holders.

dTRINITY is a decentralized stablecoin protocol that issues dUSD, a USD-pegged stablecoin backed by exogenous on-chain reserves of other USD-denominated stablecoins.
