SIGN Art is a blockchain-certified online gallery of digital art. Artists have the option to permanently link their work to a unique non-universal token, or NFT, to be sold as single pieces or limited editions. Collectors can use the platform to display their NFT collectibles, transfer or gift them to any Waves account, and sell them on the secondary market.
The SIGN Art dApp is built on top of the Waves protocol, performing instant transactions with fixed low-cost fees. For every buy request, NFT will mint coins on the chain for free.
The platform requires the $SIGN utility token for artists to manage profiles and create. Digital creations can be sold for $SIGN, $WAVES or $USDN.

The old currency SICA is upgraded to SIGN.
