Polkadot Eyes Native DOT-Backed Algorithmic Stablecoin pUSD

Polkadot is considering a community-backed proposal to launch pUSD, an algorithmic stablecoin fully backed by DOT tokens. The plan has early majority support but revives debate around the risks of algorithmic designs, especially after Terra’s collapse.

Polkadot’s ecosystem could soon see the launch of a native stablecoin, as community members rally behind a proposal to create pUSD, an algorithmic token fully backed by DOT.

Proposal gains strong early support

The idea, introduced on Sunday by Acala co-founder and Polkadot chain CTO Bryan Chen, outlines a plan for Polkadot to develop a decentralized stablecoin pegged to the U.S. dollar. Unlike centralized alternatives like USDT and USDC, the proposed pUSD would be exclusively backed by Polkadot’s native DOT tokens.

The system would be powered by Honzon, Acala’s collateralized debt position (CDP) protocol, and is designed to reduce reliance on external stablecoins. According to the proposal, more than three-quarters of current votes are in favor, with around $5.6 million worth of DOT already cast — equal to over 1.4 million tokens. Voting will remain open for another 24 days.

Chen argued that the move is essential to strengthening Polkadot’s economic base:

“Polkadot Hub should have a native DOT-backed stablecoin because people need it and otherwise we will haemorrhage benefits, liquidity and/or security.”

How the stablecoin would work

The pUSD token would operate as an overcollateralized debt token, with DOT serving as the only collateral. Users would be able to mint stablecoins by locking DOT in smart contracts. The design also includes an optional savings module, giving holders the ability to lock up pUSD and earn interest from stability fees.

Algorithmic stablecoins aim to track fiat currency values without relying on centralized collateral. Instead, they leverage onchain assets, smart contracts, and programmed economic incentives to maintain their peg.

The risks of algorithmic stablecoins

While the model promises greater decentralization and fewer points of regulatory control, it remains highly controversial. The spectacular collapse of TerraUSD (UST) in 2022 continues to loom over the industry, serving as a stark reminder of the potential risks.

Still, supporters argue that with careful overcollateralization and robust governance, Polkadot’s approach could succeed where others have failed. Analysts like Ki Young Ju of CryptoQuant have also noted that algorithmic stablecoins could create so-called “dark stablecoins” — assets that resist sanctions and regulatory oversight — raising fresh policy concerns.
