Layer 1 blockchain Polkadot has put forward OpenGov Proposal No. 1944, a community-drafted plan to launch dotUSD, a native decentralized stablecoin intended to serve as the ecosystem's primary stable-value instrument. The proposal is currently under governance voting and requests an allocation of $5 million from Polkadot's treasury to seed initial liquidity for a DOT–dotUSD pool on the Polkadot Asset Hub. Half of that amount would be deployed in USDT to mint dotUSD, with the remaining $2.5 million supplied in DOT. Under Polkadot's OpenGov framework, the network's on-chain governance system, approval and treasury spending are decided by DOT holders voting directly on referenda — placing the decision with the community rather than a corporate issuer or single entity.

The rollout is structured in two phases. The first is already live on-chain and introduces a stability-backed issuance mechanism: users can mint dotUSD one-to-one against USDT, subject to a supply cap, without requiring price oracles, collateral vaults, or liquidation logic. The second phase will activate the full over-collateralized system, built around a DOT collateral vault, oracle integration, a stability pool, and liquidation and redemption mechanisms. Notably, the proposal formally distances the Polkadot Community Foundation from operational involvement, emphasizing that dotUSD would have no issuer and would function autonomously through on-chain logic.

Liquity-Inspired Vault Model Anchors Peg Stability and Network Sovereignty

The design draws heavily on the architecture pioneered by Liquity v2, adapting its vault-based model to Polkadot's context. Users lock DOT and mint dotUSD at a value below the deposited collateral — a 150% collateralization ratio in the illustrative case — with positions falling below the minimum threshold subject to liquidation via a stability pool. In a distinctive market-driven feature, borrowers set their own interest rates, rather than rates being determined algorithmically or by protocol governance as is common in decentralized lending — which determines their position in the redemption queue: vaults with the lowest rates are redeemed first, producing an organically discovered interest rate curve shaped entirely by participants' preferences.

Peg stability rests on two complementary arbitrage channels. When dotUSD trades above $1, minting and selling adds supply; when it trades below, buying and redeeming for a dollar's worth of DOT generates upward pressure. A capped stables buffer, redeemable at par without touching DOT collateral, provides an additional peg anchor intended to reduce reflexivity — the bidirectional dependency between the stablecoin's health and the value of the collateral asset itself.

The proposal explicitly frames the absence of a native stablecoin as a structural deficiency. Ecosystem participants currently rely on centrally issued instruments such as USDC and USDT, which carry issuer-controlled freeze and blacklist capabilities, or on decentralized stablecoins from other networks that lock no DOT and accrue value elsewhere. dotUSD is positioned to close this gap, particularly as Polkadot's economic reforms — including a hard cap of 2.1 billion DOT and the Dynamic Allocation Pool — call for dollar-denominated remuneration of validators, nominators, and treasury operations. In that framing, a DOT-backed native stablecoin would allow the network to denominate its obligations in dollars while retaining full sovereignty over issuance and settlement. Attention now turns to the governance vote itself: its outcome will determine whether the $5 million treasury allocation proceeds and whether the phase-two vault system advances from design to on-chain activation.
