Android SPV wallets by Guarda

All Guarda single-currency wallets are available in open-source. The wallets are designed to store, manage, transfer and receive cryptocurrency. The applications also include an option to purchase coins with a banking card and top up wallets via the built-in Exchange service.

Guarda does not store any personal information, wallet data or private keys of our clients. The private key is stored in the mobile device’s secure memory and deletes itself if the user logs out from the wallet. In order to secure the funds, a backup of the private key or the json backup feature are created. A pin code access is also available.

How to install

If you want to add your own coin you need to discover of this files: app/src/btc/java/com/guarda/ethereum/managers/WalletManager.java - for BTC-like app/src/eth/java/com/guarda/ethereum/managers/WalletManager.java - for ETH-like

In other cases you need to follow the existing API of WalletManager.java and implement methods for creating and restore wallet, generating a public address and creating a transaction (or something else specific for your coin).
