changeangel.io is a crypto to crypto, wallet to wallet, no-custody, swap exchange service. The first currencies to be listed for direct swapping are: DGB, POT, GRS, DCR, LTC, BTC, ETH and BTG. But, there is more to the changeangel story. We are on a mission to create sustainable ways to support non ICO, open-source, decentralised blockchain development. This means that as you buy your favourite cryptos, you are also supporting your favourite blockchain development. To start, we will donate a portion of swap revenue to DigiByte, PotCoin, Groestl, Decred and LiteCoin to continue their development. As our platform grows, we plan to support additional open-source, non-profit blockchain projects. changeangel will also employ innovative blockchain solutions to enhance our platform, develop new products and promote dApp integration. Currently, we are using AntumID / Digi-ID for sign-in / sign-up authentication. AntumID is powered by DigiByte blockchain technology. At changeangel we believe we can create The "Swap Exchange for Social Good." It is our hope that other businesses will join our endeavour to support open source blockchain development through sustainable efforts.
