Aster, a decentralized exchange backed by YZi Labs, has expanded its partnership with World Liberty Financial (WLFI) to introduce USD1-denominated perpetual contracts. This initiative includes trading incentives such as WLFI token rewards and fee discounts on USD1 trading pairs, aiming to boost USD1 liquidity and support the launch of Aster's new Layer 1 blockchain, Aster Chain. The partnership allows users to use USD1 as collateral, reducing reliance on a single stablecoin and enhancing trading flexibility. Aster now supports perpetual contracts in USD1 for BTC, ETH, and SOL, with plans to add more pairs. The exchange offers a 0 bps maker fee and a 0.5 bps taker fee for USD1 pairs, significantly lower than USDT pairs. Incentives include up to 2.5 million WLFI tokens distributed monthly based on trading activity.
