Crypto users in Berlin are often experienced and care who controls their keys. A self custody wallet keeps keys on the device; a custodial wallet holds them for the user. That one choice decides most of the legal and technical work. Startups also build embedded wallets inside games, loyalty apps or ticketing so users never see a seed phrase.
Custody is a regulated service. Under MiCA, providing custody and administration of crypto assets for clients requires authorisation, which in Germany runs through BaFin, and anti money laundering checks apply, including the travel rule for transfers. Self custody software is treated differently, but features such as built in swaps or fiat on ramps through partners need careful review. Mobile wallets must also follow Apple and Google store policies on crypto, which change from time to time. Push notifications, address books and transaction history also shape whether people keep the app installed after the first week.
Ask a provider how private keys are generated and stored, and whether they use secure hardware on the device. Ask how recovery works if a user loses the phone. Ask which chains and tokens are supported at launch and how new ones are added. Request a security review by an outside firm before release, since wallet bugs cost users money directly.
This is our own list, and we rank ourselves first. The other studios each show an office in or near Berlin on their own website and are worth a call if you are comparing crypto wallet providers.
