We'd like to introduce the only fully Open Source, free multi-asset and multi-platform cryptocurrency wallet in the world.

We find it absolutely crucial that a cryptocurrency wallet should be completely Open Source. We explained why we think so here: https://steemit.com/source/@hodler.tech/hodler-the-only-multiwallet-that-s-open-source-and-why-it-matters

Basic specification of HODLER Wallet:

1. You have a full control over your private keys, nobody else but you can access them, you can export them to other wallets.
2. No private data of the user is ever collected.
3. Transactions are always generated and signed on your device. No sensitive data is ever send to an external server.
4. Don't trust, verify - thanks to being fully Open Source, the application is completely transparent. Any modification or update of the software is immediately verified by the community of security experts all around the world.
