Features of PB Wallet

PB wallet is based on the concept of sharing, but a great experience as a cryptocurrency wallet app. Users can link multiple devices, but the wallet is managed for each device and evaluated on a per-user basis.


Credit score
by sharing

Manage your wallets
like email

Manage by device
Evaluate by user

Payee accounts
multiple addresses

- Wallet
- Payee account

Like "receive@alice.btc", the wallet is represented by "wallet name@user name.cryptocurrency", and you can intuitively understand who created the wallet and what the wallet is used for.

Payee account can have multiple wallets and set payment percentages. Multiple addresses can receive cryptocurrency according to the ratio in one transaction.


Wallet sharing

PB wallet does not have private key import function and backup function. This is because sharing to other devices can provide a safe backup.

Encrypt with device key

Search for the device you want to share and encrypt it with your device key
