Signature Chain (SIGN) is an online platform that enables the certification of all data and documents on the decentralized Waves Blockchain.

About Signature Chain

Signature Chain decentralizes a mainly centralized procedure called data authentication. Normally a notary is charged with the authentication of data, SIGN replaces the notary with the Waves blockchain. This makes data authentication very efficient compared to industry standards.


In an industry that can take days or weeks to certify data at a high cost, the SIGN Web App can be used by anyone at any time to certify data instantly at a cost much lower than its centralized counterparts.

The SIGN Web App was released in 2018, as it continues to expand, it has opened up more features. Such as Mutual agreement certifications, Mass Transfers (from $SIGN token) as well as an easy to use ‘Verification Explorer’. With the explorer anyone can check whether a document has been certified in the past, and by which address.

Project attention

The development of Signature Chain has not gone unnoticed. Accounting firm Moore Cayman (known for audits such as Tether) expressed an interest in this evolving technology and decided to adopt the service, which includes many of their clients, including nearly 200 cryptocurrency-focused funds. These include BR CAPITAL, Gluwa Capital, Hamilton Investment Management, Lantern Ventures, Lima Capital LLC, Nalu Capital, Satoshi Holdings and Warp Capital. More entities have expressed their interest in adopting the SIGN Web App and opened their own white label of the app.



In addition to the SIGN Web App, Signature Chain has taken the initiative to target specific markets more directly. The first product of this initiative is SIGN Art, a digital art platform built on the Waves blockchain.

Launched in early 2021, the platform will allow creators to certify the authenticity of their art in their own digital gallery, as well as the option to sell their works through the use of NFTs. Thanks to the platform being on the Waves blockchain, it solves a much-discussed problem of energy efficiency in the crypto art industry, as well as the problem of high fees and slow transactions on other blockchains such as Ethereum. The platform currently hosts approximately 500 artists, who have uploaded 5,778 artworks to the platform, with 4,674 sales made as of January 12, 2022.

Anyone with a Waves address is able to connect and collect NFTs on the platform. In addition to the usual features like Coin, Sell, Burn, and Collect, SIGN Art has some unique features as seen in the image below.


In addition to data authenticity certificates that solve the major problem of plagiarism in the immature market of NFTs. The platform has desirable features such as lazy minting; NFTs are only minted when they are sold. As well as a 3D Art gallery for all Approved creators on the platform.
