SIGN

Launched on 11 September 2018 by an international team, Signature Chain describes itself as a dApp on the Waves Platform that provides data certification, along with mutual agreement certificates and e-mail certificates. The dApp supports FIAT transactions to purchase SIGN tokens and requires no browser extension and/or download.

As of mid 2020, Signature Chain has started work on SIGN Art, a certified digital art gallery utilizing the main sign-web.app certification functions to prove the authenticity of digital art source files. On top of this, SIGN Art offers a digital art NFT market, the Signature Chain team has received a grant from the Waves Association to develop and grow SIGN Art.
