What is it?

It's a Telegram app that allows to:

  1. Send Ethereum transactions and ERC20 tokens via Telegram messenger (only client side)

  2. It uses Celer Network for the cheap and fast transactions.

  3. It uses ShapeShift to allow you to exchange ETH and other cryptocurrencies in the convenient and trustless way.

  4. It uses Rhombus to have tampered resistant exchange rates (Example: (Support to usd-eth eth-usd usd-xdai xdai-usd dai-usd usd-dai usd-btc btc-usd)

  5. It supports xDAI, DAI, BUFF, BTC and ETH on Mainnet. It means you already can pay for the food on the EthDenver19.

Detailed Project Description (no more than 3-4 sentences)

That's a secure messenger client to make transactions which is super easy to use. You don't need to download anything and you can send transactions via @nickname. We were inspired by WeChat payments. We build it not only on ETH but also on BTC and second layer of ETH called Celer Network. That means - very low fees and fast payments!
