Cryppter 1.3.1

Cryppter is a free wallet application designed to manage a small set of cryptocurrencies with user-owned keys and local signing.

• Supported coins: BTC, LTC, ETH.
• Supported tokens: Flame, USDt.

Core functionality includes:

• Send, receive, and store the supported cryptocurrencies.
• Decentralized exchange for supported crypto pairs.
• QR code workflow: scan payment addresses, generate your own, or save as an image to share with a payer.
• Full payment history accessible, including transactions originated from third-party wallets or exchanges.
• Dynamic fee selection for blockchain processing with slow, standard, and fast options, adjusted to current network conditions.
• In-app messaging to contact support with questions or suggestions.

Security model and best practices:

• The adage Not your keys, not your coins applies; keys stay on-device and users are encouraged to back up seed phrases on paper for recovery.
• With the seed phrase, users can restore the account on another device or manage coins with another program using the saved keys.
• All payments are originated from the wallet app and signed locally; the server stores no sensitive data and cannot restore coins if seed phrases or private keys are lost.
