Bitwala

Bitwala is a Berlin-born crypto finance app that combines a self-custodial wallet, a euro account and a Visa debit card in one interface. Users fund the account by SEPA transfer, buy bitcoin, ether or USDC, and spend from the wallet with conversion at the moment of payment; wallet access runs through the app's key management rather than a written seed phrase, and card spending in the euro area settles at the day's rate.

Euro and on-chain balances appear side by side, an outgoing payment can draw on either leg, and transfers and card spending share one limit structure. The brand was founded in 2014 and renamed itself Nuri in 2021; the original company filed for insolvency in August 2022, ceased operations that October and moved roughly 250,000 customers to Vivid Money. It later returned as a self-custody wallet plus card product covering bitcoin, ether, USDC and euros across several European Economic Area countries, with online payments and ATM withdrawals drawing on the same balance.
