British challenger bank Revolut is rolling out a new savings tool, which will allow app users to save their spare change, the bank announced today.

The app will allow users to add spare change from their daily purchases to the tool, called Vaults, in any of the 25 currencies (as well as cryptos bitcoin, Litecoin, and ether) that Revolut presently supports.

Revolut customers can schedule regular payments or one-offs into their Vault accounts, and funds can be transferred out of the accounts instantly, the bank said.

Nikolay Storonsky, CEO for Revolut, said in a statement that the bank has “had thousands of people in our community asking for this feature.”

Based in London, the bank has more than 1.7 million customers in Europe, and has processed 60 million transactions (with an average of 15 million transactions made per month, according to the bank).

Revolut is expected to roll out in North America later this year.
