Polkadot governance is considering dotUSD, a protocol-native decentralized stablecoin proposed as its primary stable-value instrument. The proposal would create dotUSD on Asset Hub, establish a DOT-dotUSD market and eventually let users mint it against DOT collateral.
Polkadot Sets 2-Phase Plan for dotUSD Stablecoin Launch
The referendum proposes creating dotUSD as a protocol asset and recognizing it as Polkadot’s stablecoin. It also calls for a DOT-dotUSD liquidity pool on Asset Hub, seeded with treasury liquidity. The live referendum currently lists $1.5 million in USDT and $1.5 million in DOT for the pool, while the supplied proposal text cites $2.5 million for each asset.
The proposal matters because Polkadot applications and treasury operations currently rely on external stablecoins. A native stablecoin could reduce that dependency while giving DOT a direct role in collateralized borrowing and liquidity. Users could gain a dollar-denominated asset without carrying DOT volatility directly.

Polkadot Uses 1 DOT-Backed Model to Support dotUSD Growth
dotUSD is planned as an over-collateralized stablecoin, with its full design drawing on Liquity v2. In the proposed second phase, users would lock DOT in vaults and mint dotUSD below the value of their collateral.
The system would use liquidations, a stability pool and redemptions to manage falling collateral values and support the dollar peg.
A notable feature is borrower-selected interest rates rather than one protocol-set borrowing rate. Lower-rate positions would face redemption priority when dotUSD trades below its target, while borrowers could choose higher rates to reduce that risk. This creates a market-discovered rate curve, potentially giving DOT a flexible credit market.
Polkadot Eyes 3 Economic Uses for dotUSD Across Its Network
The rollout is divided into two phases to limit technical risk during deployment. Phase one uses a capped buffer backed one-to-one by USDT, allowing dotUSD circulation without relying on an oracle or DOT liquidation system. Phase two adds DOT-backed vaults, oracle integration, stability mechanisms and redemption functionality once ready.
The design also addresses a key risk: reflexivity between DOT and dotUSD. If DOT falls sharply, collateralized positions could face liquidation, potentially adding selling pressure to the asset supporting the stablecoin.
The proposal therefore emphasizes stability-pool protection, redistribution mechanics and a separate stablecoin buffer to reduce forced DOT sales during volatility.
For DOT, the significance is economic infrastructure rather than another token launch. The proposal calls dotUSD “the instrument which makes dollar-denominated budgeting possible on-chain.”
It also links the asset to future stablecoin payments and treasury operations, while the Asset Hub pool could deepen application liquidity. The next step is governance approval and implementation across the network now.
