Kraken, the US cryptocurrency exchange, has listed Sign (SIGN) and enabled deposits and trading on its platform, adding a token linked to a blockchain infrastructure company that is building digital identity and payment systems for sovereign governments.
Sign describes itself as a global digital infrastructure company that powers sovereign nations through secure, large-scale systems for digital currency, digital identity and real-world asset tokenisation.
The company, founded in 2021, has raised more than $30 million from investors including YZi Labs, IDG Capital and all three regional arms of Sequoia Capital, and is working with governments in Thailand, South Korea, the UAE and Sierra Leone on national-scale blockchain deployments.
Its technology stack, branded as Sovereign Infrastructure for Global Nations (S.I.G.N.), provides three core layers: a digital currency rail supporting central bank digital currencies and regulated stablecoins; a national identity and credential system using verifiable on-chain records; and a programmable capital distribution layer for government grants, benefits and incentive programmes.
The SIGN token serves utility functions across the ecosystem, including creating attestations (cryptographically verified records of agreements or data), accessing decentralised storage and participating in ecosystem services.
Kraken said funding is available through its Funding page and users can add the asset via the standard deposit workflow, but warned that tokens must only be deposited on networks the exchange supports, as deposits made on unsupported networks will be lost.
Trading via the Kraken App and Instant Buy will be enabled once liquidity conditions are met, meaning a sufficient number of buyers and sellers must enter the market for orders to be matched efficiently.
The exchange noted that geographic restrictions may apply and reiterated its policy of not disclosing which assets are under consideration before launch, directing customers to its Listings Roadmap for future additions.
