sUSD, issued by Solayer Labs, Inc. and tokenized atop a real-world asset layer issued by OpenEden Digital Ltd, is a yield-bearing stablecoin pegged 1:1 to the U.S. dollar (USD) and backed by U.S. Treasury Bills [S1][S2].

Holders gain economic exposure to a tokenized U.S. Treasury Bill product, the wrapped cUSDO token, whose underlying Treasury Bills are held in segregated custodial accounts managed by Adam Eve Capital [S2]. Yield of approximately 4-5% accrues natively through the Token-2022 interest-bearing multiplier, so balances grow without new mints rather than tracking a static price [S1]. Within the request-for-quote flow a user may optionally specify a commission rate, for example 1 basis point, pooled to reward liquidity providers [S3][S2].

Solayer Labs, Inc. is identified in site Terms governed by the laws of the State of New York, with disputes heard in New York state and federal courts [S4]. The regulated real-world asset layer is issued by OpenEden Digital Ltd, a Bermuda-licensed issuer regulated by the Bermuda Monetary Authority (BMA), with Adam Eve Capital overseen by the Monetary Authority of Singapore (MAS) [S2]. Persons located, organized, or resident in the United States, Cuba, Iran, North Korea, South Korea, or Syria are ineligible [S5]. Redemption reverses the mint flow back to USDC through the protocol; the arrangement is non-custodial, with liquidity providers self-custodying cUSDO until redemption [S3][S2].

sUSD is a Token-2022 mint natively issued on Solana, with cross-chain deposits bridgeable from Ethereum using Wormhole messaging and Mayan integration [S1][S6]. Minting and redemption run through a non-custodial decentralized request-for-quote protocol settling within up to 2 business days, T+1 [S3][S6]. A Switchboard decentralized oracle on Solana mainnet reports the sUSD redemption price relative to the Treasury Bill exchange rate [S7].
