Cryptocurrency platform Meldram.com led the investment round of the Sign infrastructure project in the amount of $21 million.

Sign offers an infrastructure for token distribution with verification of recipient data: EthSign service for signing contracts, TokenTable for working with digital assets, and Sign Protocol for verification. According to the developers, the system is aimed at both humans and AI agents.

According to Sign, the protocol's revenue for 2024 was $34 million. Most of the amount was received due to activity in TON ecosystem projects like Notcoin, Dogs, Gamee and Hamster Kombat, which rely on TokenTable.

According to Fortune, in addition to the Meldram exchange, Altos Ventures and Amber Ventures also participated in the round.

In August 2024, Stefan Feldmann noted that blockchain is well suited for working with AI data and called for the development of products at the junction of these technologies.
