Features
Free and Open Source
Just like Bitcoin core, BitSai is free and open source and will always stay that way.
Modern
BitSai leverages all the modern and latest Bitcoin soft and hard forks to bring a modern experience to your Bitcoin finances
Cross-platform
We aim to be as cross-platform as possible. By being a web app, virtually any platform that supports modern web browser can use BitSai
Secure
Your wallet is encrypted locally and all of the transactions are signed locally. Bottom line: Bitsai never stores anything on external servers and your private keys never leave your device.
Forgiving and no Lock-In
When initially creating a wallet, Bitsai generates for you a mnemonic seed that you can save and use in any other bitcoin wallet (BIP39 compliant). Additionally, even if your device malfunctions or gets lost you can use that same mnemonic seed to recover all your funds.
Fast
BitSai aims to be as fast as possible by using the Blockstream API to process transactions.
Private
Your private keys are encrypted and stored locally in your device. And every time you generate a receiving address you get a random one so that each incoming transaction can be only be associated with a single address.
User-friendly and elegant UI
Sending and receiving bitcoins could not get easier than this. BitSai is so easy, even a one-year-old can start transacting bitcoins with it.
Portable
Take BitSai app everywhere you go. If your platform supports a browser then it most certainly supports BitSai.

Disclaimer: BitSai is still in ALPHA so it is highly recommended to use it in testnet only (testnet is a bitcoin network where all btc are worthless).
With that being said, we are not responsible for any loss of funds (eg. real btc in mainnet), check LICENSE.
