The Bitcoin Account.
Bitcoin first. Stable dollars and euros when useful. Local cash in and out.
One simple self-custodial account.
Bitcoin first. Stable dollars and euros when useful. Local cash in and out.
One simple self-custodial account.
Send Bitcoin anywhere. On-chain or over Lightning.
Hold stable dollars and euros.
Swap to local currency in seconds.
Bitcoin was built as peer-to-peer electronic cash.
Stablecoins are digital dollars and euros when you want stable value.
Bank, card and mobile money are ways in and out.
Anyone should be free to own money and send it directly to anyone else.
No middleman. No gatekeeper. Like handing someone cash.
Bitcoin made that possible. We make it simple enough for everyone.
The wallet is yours.
Cards, banks and payment providers are services around it.
Nuri can disappear. A partner can disappear. Your self-custodial wallet is designed to remain yours.
Use regulated services without giving them custody of your wallet.
Card, banking, e-money and local payment services operate under their own licences and terms.
We grew up building internet money.
Berlin. 2012 → today. Mining. Exchanges. Wallets. Smart contracts. Protocols. Payments.

Bitcoin since the early 2010s. Wallets, protocols and payments.
