Hyperliquid enables USDT as borrowable asset on testnet, mainnet upgrade next

Hyperliquid just flipped the switch on USDT borrowing in its testnet environment, marking the second stablecoin to join the platform’s portfolio margin feature. The mainnet rollout is slated for the next network upgrade, which would give traders on the decentralized exchange access to the world’s most widely used stablecoin as a borrowable asset.

What portfolio margin actually does here

Instead of maintaining separate pots of capital for spot trades and perpetual contracts, Hyperliquid lets users manage everything from a unified account. The collateral? HYPE tokens, the platform’s native asset.

In English: you deposit HYPE, borrow stablecoins against it, and trade both spot and perps without shuffling funds between different margin accounts.

Until now, the only stablecoin available for borrowing under this system was USDC, which has been live since the portfolio margin feature launched in December 2025. USDT is the natural next step, given that Tether’s stablecoin remains the dominant trading pair across crypto markets by a wide margin.

The platform has also signaled plans to add USDH and BTC as borrowable assets in the future, suggesting this is part of a broader roadmap rather than a one-off addition.

Hyperliquid’s infrastructure play

Hyperliquid isn’t building on Ethereum or any existing Layer 1. The platform runs on its own custom blockchain, purpose-built for high throughput and low transaction costs.

The network’s validator set has expanded from 24 to 27 as of May 2026, a modest but steady growth trajectory that reflects the platform’s ongoing decentralization efforts.

One notable advantage Hyperliquid maintains over centralized competitors: no KYC requirements.

The testnet phase serves as a crucial stress test before real capital is at risk. Portfolio margin systems are inherently complex because they involve cross-collateralization, meaning a bug or miscalculation in one area can cascade across a user’s entire account.
