Revolut now allows its US users to trade cryptocurrencies by partnering with Paxos. This was made possible by New York-based Paxos getting a new brokerage service to let merchants offer crypto trading services.

Revolut US, the American division of the online bank, is the first client of Paxos. Paxos CEO Chad Cascarilla compared its new brokerage with a “plug-and-play” service that can be used by any company from payment firms to retailers to offer crypto to their customers with Paxos on the backend.

“It’s clear many firms want to offer crypto but are finding it’s difficult to build the regulatory and technological infrastructure to do that,” he told Fortune. “This allows anyone, no matter what type of firm they are, to do that.”

Paxos is a legal trust company, which means it retains all the assets it holds on its customers’ behalf, which allows it to deal with traditional financial firms that have to otherwise keep away from digital assets because of regulation or another risk.

Paxos currently offers a fiat-pegged stablecoin Paxos Standard and a crypto token backed by physical gold.

Just a few months back, in late March 2020, Revolut launched its app and service in the US. Its partnership with the Metropolitan Commercial Bank enabled the company to offer its debit card to US customers.

Now, the European fintech allows its US users to buy, hold, and sell Bitcoin (BTC) and Ethereum (ETH) from the Revolut app, but you can't send and receive crypto from third-party wallets. The feature is available in 49 states due to some regulator issues in Tennessee.

For now, only the top two cryptos are available, unlike its European counterpart, where it offers more cryptos such as XRP, Litecoin (LTC), and Bitcoin Cash (BCH). The company is working on adding more cryptos to the list.

For the first 30 days, Revolut is waiving the fees, which usually is 2.5% for a free Revolut account while Premium and Metal subscription will pay 1.5% in conversion fees. There are some monthly limits on currency exchange for free user users, which means you have to pay a 0.5% fee above that limit.

Square’s Cash App and commission-free Robinhood also let US users buy cryptocurrency via their apps.
