Aster lists WLFI-USD1 pair for spot trading

@Aster_DEX has added a WLFI-USD1 spot trading pair, marking the latest step in its growing partnership with @worldlibertyfi, the decentralized finance platform behind the $USD1 stablecoin.

What Is USD1?

USD1 is a fiat-collateralized stablecoin pegged 1:1 to the US dollar, with each token in circulation backed by a corresponding dollar of reserves held in cash deposits and short-term US Treasury securities. The custodian is BitGo Trust Company, a South Dakota-chartered trust that also custodies digital assets for institutional clients. As of mid-2026, USD1 circulates at roughly $4.6 billion in supply, placing it inside the top five fiat-backed dollar tokens by market capitalisation.

Aster, a trading ecosystem backed by YZi Labs, has been expanding its collaboration with World Liberty Financial, introducing USD1-denominated perpetual contracts and new trading incentives including $WLFI token rewards and reduced fees on USD1 pairs. The addition of a dedicated spot pair for WLFI-USD1 extends that relationship into the exchange's spot markets.

Rewards Campaign and Trading Incentives

Aster first adopted $USD1 as a settlement currency for perpetuals on traditional assets. Traders holding USD1 can use it directly for trading commodity perpetuals, covering assets such as gold and crude oil, without converting to other stablecoins first.

Alongside the broader partnership, Aster launched its USD1 RWA Boost: Phase 1 campaign with World Liberty Financial, featuring 125,000,000 $WLFI and 6,250,000 USD1 in rewards. The campaign runs from August 31 through December 31, 2026, covering pairs including SPCX/USD1, CL/USD1, XAU/USD1, and others.

Users earn Trading Points through taker volume on eligible USD1 pairs, which determine their share of the USD1 reward pool, while Open Interest Points are earned by holding eligible positions and determine their share of the $WLFI reward pool. Traders using Single Asset Mode with USD1 as collateral receive a 2x boost on OI Points. Rewards are calculated across weekly epochs and distributed the following week.

The integration is intended to support USD1 liquidity on the platform, laying the groundwork for Aster Chain, the project's newly launched Layer 1 blockchain.
