Investment firm Spiko has integrated Coinbase’s stablecoin payment infrastructure into two regulated EU Treasury-bill funds, allowing eligible investors to fund subscriptions and receive redemption proceeds using USDC and EURC.
Coinbase said Tuesday the integration covers Spiko’s EU T-Bills Money Market Fund and US T-Bills Money Market Fund. Both are structured as Undertakings for Collective Investment in Transferable Securities, or UCITS. Coinbase Payments will provide the payment, wallet and application programming interface (API) infrastructure, with the transactions settling on Base, Coinbase’s layer-2 network.
The exchange said the products are the first UCITS funds in Europe to accept direct stablecoin payments.
The move into UCITS funds comes as net sales of the assets rebounded in April, the latest data from trade group EFAMA showed on Monday. UCITS saw net inflows of 104 billion euros that month, compared to net outflows of 41 billion euros in March. Net sales reached a new record in 2025, totaling 828 billion euros and surpassing the previous 2021 high of 813 billion euros.
Tokenized funds push toward 24/7 utility
Coinbase described the integration as an example of how stablecoins could reshape payments infrastructure for mutual funds by removing bottlenecks for investors as they enter and exit a product. It positions stablecoins as settlement infrastructure, connecting onchain capital with regulated investment funds.
Investors can submit subscriptions at any time, including weekends and holidays. At the same time, redemption proceeds can be delivered to a stablecoin wallet within minutes after a position is liquidated.
Despite this, round-the-clock stablecoin transfers do not necessarily mean that the underlying fund continuously processes subscriptions and redemptions. Spiko said the Coinbase integration introduces a new payment method rather than changing the funds themselves.
Cointelegraph reached out to Coinbase for more information on order execution, but did not receive a response before publication.

Other asset managers have tested ways to provide 24/7 access to tokenized funds. In February, WisdomTree received approval for round-the-clock secondary trading and instant USDC settlement of its tokenized Treasury fund, with liquidity supplied by its broker-dealer while primary fund processes remained unchanged.
Tokenized money market funds are also increasingly being used as infrastructure beyond subscriptions and redemptions. In February, Franklin Templeton and Binance introduced a program allowing institutions to pledge tokenized fund shares as off-exchange trading collateral while the assets remain in regulated custody
