Justin Sun’s USDD stablecoin has launched on Ethereum, offering up to 12% annual percentage yield (APY) and a Peg Stability Module (PSM) for 1:1 swaps with USDT and USDC.

**Justin Sun’s USDD Stablecoin Launches on Ethereum: A New Challenger in the $2.5T Market?**
The stablecoin arena is heating up. As Ethereum’s stablecoin supply hits $165 billion, Justin Sun’s USDD has entered the fray, aiming to carve out a niche in a sector dominated by Tether’s $169 billion USDT. Launched natively on Ethereum with a Peg Stability Module (PSM) and up to 12% annual percentage yield (APY) rewards, USDD is betting on decentralization and incentives to attract users—and challenge the status quo.
**A New Player with Big Ambitions**
USDD, an overcollateralized algorithmic stablecoin, originally debuted on TRON but now has an Ethereum contract live since September 8, following a CertiK audit. The PSM allows seamless 1:1 swaps with USDT and USDC, promising efficient liquidity. To sweeten the deal, USDD kicked off an airdrop on September 9, offering Ethereum users tiered APY rewards starting at 12%, which gradually drop to 6% as adoption grows. Rewards accrue every eight hours via the Merkl Dashboard, a move designed to lure early adopters with immediate returns.
“From now on, everyone has a decentralized choice when it comes to stablecoins! USDD is growing!” Sun proclaimed on X, framing the launch as a step toward broader multi-chain expansion. Upcoming upgrades include sUSDD, an interest-bearing variant that generates passive yield on-chain, hinting at long-term ambitions.
**Collateral, History, and Hurdles**
USDD’s 204.5% collateral ratio—backed largely by TRON’s native token (TRX) after Sun withdrew $726 million in Bitcoin collateral in August—aims to prevent destabilization. Yet the token’s past has been rocky: it dipped to $0.983 during Terra’s 2022 collapse and fell further to $0.97 during FTX’s meltdown. These scars underscore the risks of algorithmic stablecoins, even with robust collateral.
**Tether’s Dominance and a Crowded Field**
Tether remains unshakable. TRON processes $23–25 billion in daily USDT transfers, dwarfing Ethereum’s $20 billion. With TRON’s USDT circulating at around $80 billion and Binance controlling $44 billion in stablecoins, Tether’s liquidity and global reach are unmatched. But competition is growing.
MetaMask’s mUSD, Paxos’s revenue-sharing USDH, and rapid growth from EURC and PYUSD signal a fragmented market. Meanwhile, regulatory frameworks like the EU’s MiCA and the U.S. GENIUS Act are creating pathways for compliant rivals, while Asia’s Singapore, Hong Kong, and Japan are tightening rules to attract institutional players.
**USDD’s Uphill Climb**
Despite its incentives, USDD’s $450–$460 million market cap in mid-September 2025 is just 0.3% of Tether’s. Liquidity on Ethereum has improved via the PSM, but depth still lags behind USDT and USDC. Worse, USDD’s reserves remain heavily tied to TRX, exposing it to volatility.
For USDD to survive, it needs deeper liquidity, diversified collateral, and real-world use cases. Sun’s vision of a “decentralized choice” is bold, but the road ahead is steep. With Tether’s dominance and a rising tide of competitors, USDD’s success hinges on whether its incentives can translate into lasting adoption—or if it’s just another fleeting spark in a crowded stablecoin landscape.
What do you think? Can USDD disrupt Tether’s reign, or will it fade like so many before it?
