Non-custodial wallet architecture — complete technical documentation

Non-Custodial by Design

Bad Place is non-custodial. Your private key is generated and encrypted on your device, and our servers never store it. Only you can move your funds.

Not Your Keys? Not Here.

We hold zero key material. Your 12-word seed phrase and private key exist only on your device, encrypted with a key derived from your PIN or wallet password. There is nothing on our servers for an attacker to steal.
