Woofun AI reports that investment firm Spiko has integrated Coinbase's stablecoin payment infrastructure into two regulated EU Treasury-bill funds, enabling subscriptions and redemptions via USDC and EURC. The integration specifically covers Spiko's EU T-Bills Money Market Fund and US T-Bills Money Market Fund, both structured as Undertakings for Collective Investment in Transferable Securities (UCITS). Coinbase Payments supplies the necessary wallet and API infrastructure, with all transactions settling on Base, Coinbase's layer-2 network. These represent the first UCITS funds in Europe to accept direct stablecoin payments.

The strategic timing coincides with a sharp rebound in net sales of UCITS assets, which recorded net inflows of 104 billion euros in April after net outflows of 41 billion euros in March. Net sales reached a new record in 2025, totaling 828 billion euros. Coinbase described the integration as a demonstration of how stablecoins could reshape payments infrastructure for mutual funds by removing bottlenecks for investors. Investors can now submit subscriptions at any time, including weekends and holidays, while redemption proceeds are delivered to a stablecoin wallet within minutes after a position is liquidated.

Spiko stated that the Coinbase integration introduces a new payment method rather than changing the funds themselves.

Woofun AI data shows other asset managers have also tested ways to provide 24/7 access to tokenized funds; for instance, WisdomTree received approval for round-the-clock secondary trading and instant USDC settlement of its tokenized Treasury fund in February.

Additionally, Franklin Templeton and Binance introduced a program in February allowing institutions to pledge tokenized fund shares as off-exchange trading collateral. This rapid adoption of stablecoin rails signals a structural shift toward continuous market access in traditional asset management.
