Metronome Synth USD

Metronome's dollar is a synthetic, minted against collateral rather than held in a bank. msUSD comes from Metronome Synth, the collateralized-debt product of the DAO-governed Metronome protocol. A user deposits accepted collateral, then mints msUSD against it as over-collateralized onchain debt, and closes the position by repaying to reclaim the collateral. Redemption therefore runs through the smart contracts and the protocol's collateral pool, not a company, and the peg leans on over-collateralization plus liquidation and arbitrage. Metronome is DAO-governed with no legal token issuer, so there is no reserve attestation or par desk to appeal to. msUSD is deployed across Ethereum, Optimism, Base and Plasma, letting the same synthetic dollar move between those chains. It sits in the family of DeFi synths where the backing is crypto collateral rather than bank reserves.
