MSUSD, issued by Main St Finance Ltd, is a synthetic, rebasing stablecoin pegged to the U.S. dollar (USD) that captures yield through advanced financial strategies, including delta hedging and smart contract automation [S1].

MSUSD tracks the U.S. dollar (USD) and is a yield-bearing synthetic dollar whose balances rebase to distribute returns [S1][S2]. Yield derives from short-duration box spreads that turn an institutional options-funding trade into onchain, market-neutral, USD-denominated accrual designed to have effectively no delta or gamma [S2]. Holding MSUSD also earns Gammas, an incentive point convertible to the $MS governance token, with rates subject to adjustment at Main Street's discretion [S2].

The platform is operated by Main St Finance Ltd, governed by the laws of the jurisdiction in which it is incorporated, with disputes resolved in the competent courts of that jurisdiction [S1]. The issuer claims no license and warns that synthetic stablecoins like MSUSD are subject to rapidly changing regulatory frameworks [S1]. The holder's claim is a synthetic dollar token, not a deposit or regulated fund interest [S1]. Users must be at least 18 years of age [S1]. Minting is permissionless and a direct redemption path exists [S2]. No segregation or security interest protects tokenholders, who safeguard their own private keys [S1].

MSUSD is a rebasing ERC-20-style token minted and redeemed permissionlessly through smart contracts via the app, with the related msY vault following the ERC-4626 standard on Ethereum mainnet [S2]. Collateral status is published through a live, cryptographically signed Proof of Reserves dashboard hosted by a third-party verifier, Accountable, showing a collateralization ratio and total reserves [S2][S3].
