Mainstreet Finance API

Mainstreet Finance integration.

Mainstreet Finance (developed by Mainstreet Labs) is a synthetic USD stablecoin ecosystem built on multi-asset collateralisation. The protocol delivers institutional-grade delta-neutral yield strategies through a dual-token system - msUSD (the synthetic stablecoin) and smsUSD/Staked msUSD (the staked version that earns yield from options arbitrage strategies).

Users deposit USDC to mint msUSD, which can then be staked into smsUSD to earn yield. The underlying collateral is deployed into CME index box spreads and options arbitrage strategies, with profits distributed to smsUSD holders.

Key features:

  • 20% protocol fee on yields (10% to insurance fund, 10% to treasury)

  • 80% of yields distributed to smsUSD holders

  • Governance-configurable cooldown period for withdrawals (up to 90 days, default 7 days)

  • Cross-chain functionality via LayerZero OFT standard
