USD1 perpetual trading went live on Aster on March 18, 2026, as part of an expanded collaboration with World Liberty Financial, the issuer of the USD1 stablecoin. The rollout adds USD1-denominated futures contracts, WLFI token rewards, and reduced trading fees, positioning USD1 as a core margin asset ahead of the platform's own Aster Chain mainnet.
What Changed With USD1 Perpetual Trading on Aster
The integration introduces USD1-denominated perpetual contracts starting with BTC, ETH, and SOL pairs, with more than 10 additional pairs planned in the following weeks. USD1 is also supported as a core margin asset and collateral, with a collateral ratio matched to USDT, which is meant to let traders use USD1 in the same way they would use any established stablecoin rather than treating it as a secondary option.
Fee Structure for USD1 Markets
To encourage early participation, Aster set maker fees at zero basis points on USD1 pairs, paired with a 0.5-basis-point taker fee. Aster's CEO, Leonard, described the fee design as intentionally built to pull early liquidity into USD1 markets while the exchange lays groundwork for Aster Chain's own trading engine.
How the WLFI Rewards Program Works
Traders active on USD1 perpetual markets can earn from a pool of up to 2.5 million WLFI tokens distributed monthly, based on trading activity, with rewards paid out weekly rather than in a single lump sum. Separately, users holding USD1 on the platform may qualify for additional platform incentive programs tied to holding the stablecoin rather than trading it.
Why Aster Is Diversifying Beyond a Single Stablecoin
Adding USD1 as both a trading pair and a collateral option reduces Aster's dependence on any single stablecoin for margin and settlement, which matters as the exchange scales toward its own Layer 1 chain. Zak Folkman, Co-founder and COO of World Liberty Financial, framed the collaboration as aiming for "functional parity" between USD1 and existing major stablecoins rather than positioning it as a secondary asset traders would only use occasionally.
Building Liquidity Ahead of Aster Chain
According to Aster, this integration is explicitly meant to support USD1 liquidity depth as groundwork for Aster Chain, the project's newly launched Layer 1 blockchain. Deeper, more diversified stablecoin liquidity on the trading engine is positioned as a prerequisite for the chain's broader rollout rather than a standalone feature.
The move follows closely behind Aster Chain's own mainnet launch, where privacy-by-default trading became the network's core differentiator, and USD1 liquidity is one of the building blocks supporting that rollout.
