About uniswap State Dollar

Unified Stable Dollar (USD) is a decentralized stablecoin on Ethereum designed to maintain a 1:1 peg with the US dollar through a collateralisation mechanism that leverages multiple stablecoins in Uniswap liquidity pools. Governed on-chain by the UniFi DFO community, users could mint USD by depositing whitelisted stablecoins, with an arbitrage process helping to stabilise its value. The token underwent several migrations: initially deployed at one contract address, then migrated to a new contract for minor updates, and later rebranded as Wrapped USD (WUSD) in an effort to incorporate features like multi-AMM support and yield sharing. Ultimately, minting was suspended in February 2021, and the token lost its peg and market utility. Today, unified Stable Dollar (USD) exists as a legacy asset within the EthereansOS ecosystem, symbolising an ambitious but ultimately challenging experiment in decentralized stablecoin design.

Uniswap State Dollar (UNISDV1) was conceived as a meta-stablecoin backed by a basket of stablecoins. It aimed to mitigate the risk of a single stablecoin depegging by pooling collateral from multiple sources. The system utilized automated market-making (AMM) protocols to maintain its peg through arbitrage; if the price deviated from $1, users could mint or redeem UNISDV1 to restore balance.

  • Decentralized Stability: It functioned as a stable, decentralized medium of exchange within the DeFi ecosystem.
  • Arbitrage Mechanism: Users could take advantage of price discrepancies through minting and redemption, helping to stabilize the peg.
  • DeFi Utility: Designed for trading, lending, and yield farming as a censorship-resistant alternative to fiat-backed stablecoins.
  • Store of Value: It aimed to be a resilient store of value by being collateralized with multiple stablecoins, reducing dependency on a single issuer.

Uniswap State Dollar was created by the DFOhub/UniFi team, which later evolved into EthereansOS. The team specialized in decentralized flexible organizations (DFOs) with on-chain governance. Governance of the stablecoin was handled by the UniFi token holders, allowing community-driven decisions, such as pausing minting or migrating contracts.

  • Initial Contract: The original UNISDV1 contract (0x84841e552A021224de716b7Be89747bb2D62D642) facilitated minting through whitelisted stablecoin pairs on Uniswap.
  • Contract Migration: A later contract (0x44086035439E676c02D411880FcCb9837CE37c57) was deployed with governance-approved improvements, enabling users to redeem collateral from the previous version.
  • Wrapped USD (WUSD): A subsequent upgrade introduced Wrapped USD (WUSD) with multi-AMM support and yield-sharing, but it did not achieve significant adoption and was eventually discontinued.

Uniswap State Dollar underwent several changes throughout its existence:

Initially launched as Uniswap State Dollar, it was later renamed to Unified Stable Dollar (USD) before its discontinuation. The transition to WUSD aimed to modernize the stablecoin, though this version was short-lived. The broader project rebranded, with DFOhub/UniFi evolving into EthereansOS, consolidating governance into a new token ($OS) and shifting away from the standalone stablecoin model.


Originally, Uniswap State Dollar was governed by the UniFi DFO, where token holders controlled protocol decisions, including minting, pausing, and contract migrations. Governance was executed entirely on-chain through transparent voting. As the project transitioned into EthereansOS, governance responsibilities were transferred to the new OS token. Since minting was halted in February 2021, the focus shifted to allowing existing holders to redeem collateral.

Uniswap State Dollar (UNISDV1) is no longer an active stablecoin:

  • Minting Halted: No new UNISDV1 tokens have been minted since February 2021.
  • Circulating Supply: The supply significantly declined as users redeemed their tokens for underlying stablecoins.
  • Depegged: The token eventually lost its $1 peg, trading below its intended value.
  • Project Dormancy: With no further development or market liquidity, the stablecoin is effectively deprecated. Though the asset remains on-chain, redemption mechanisms are no longer maintained.

Uniswap State Dollar stands as an experiment in decentralized stablecoin design, showcasing both innovative approaches to maintaining stability and the challenges of achieving long-term adoption in the fast-evolving DeFi landscape.
