Reclaim your digital life with Bitkit.

Bitkit offers on-chain and lightning transactions, as well as user-controlled social profiles and contacts; easy payments to contacts; key-based log-ins; and data streaming from private and public feeds into widgets. All these latter features have been built using Slashtags.

Synonym's mission is for users to have control over their own data and operate in a Web that is censorship-resistant, private, and free from walled gardens. Bitkit is Synonym’s crack at harmonizing such digital autonomy with a great user experience.

Bitkit is a mobile application available on Android and iOS, and implemented using React-Native.

Society, the economy, and the Web suffer from oppressive central controls, resulting in censorship, privacy breaches, and monopoly behaviors. Users need P2P tools that set them free.

Bitkit offers a Bitcoin wallet that supports both on-chain and lightning transactions. The application runs a custom, non-routing Lightning node created with the Lightning Development Kit on the user's mobile phone. By default you connect to Synonym's Electrum-Bitcoin Core server, but you can also connect to your own server. We on-board users to Lightning through our lightning service provider (LSP) Blocktank. In the future, we will also enable connections to other LSPs and peers on the network.

Users can back up their Bitcoin and Lightning keys with a standard BIP-39 seed and optional password. Lightning channel data is automatically replicated on our a backup server. The data is encrypted on the client-side before it is sent to our server to ensure privacy. You can view our code here.

The other main features Bitkit supports are as follows:

• 📱 Social profiles and contacts
• 💸 Easy payments to profiles
• 🔑 Key-based account logins
• 📊 Streaming of private and public data feeds into widgets

All these additional features are powered by Slashtags: a collection of software modules and specifications that complements the Bitcoin and Lightning stacks in the building of peer-to-peer applications, specifically to enable decentralized identities and web-of-trust reputation systems. You can view our JavaScript-based software development kit which has been used for the Bitkit wallet here.

You can experiment with Bitkit's Slashtags features in our playground. We currently support four public data widgets:

• 📈 Bitcoin Price Feed - 📲 Add to your phone
• 📰 Bitcoin News Feed - 📲 Add to your phone
• 📊 Bitcoin Block Feed - 📲 Add to your phone
• 📚 Bitcoin Facts Feed - 📲 Add to your phone

Slashtags user data is automatically replicated via our seeding server. In this way, user data is always available. In addition, it allows the user to restore all their Slashtags data from just their BIP-39 seed and optional password.
