Sign isn't a typical crypto project. It's actually two separate products: Sign Protocol, which lets you create and verify digital claims across blockchains using zero-knowledge proofs, and TokenTable, a smart contract system for token distribution and vesting.
The government angle is genuinely interesting. Sign has built infrastructure for Sierra Leone's national blockchain rollout and has deals around digital identity in parts of Asia and the Middle East. I'd want to know more about whether these are live or just announced — that distinction matters a lot.
Token launched April 2025 at $0.0666, briefly doubled, then dropped to around $0.034. Market cap is $56M, which puts it below most comparable infrastructure projects.
Use cases span smart contract signing, credential verification, airdrops, DAO governance, and government ID systems. The thesis is simple: the internet needed HTTP before it could scale. Blockchain needs an attestation layer before it can mean anything to governments or mainstream users. Sign is betting they're building it.
Whether that bet pays off depends almost entirely on whether those government deployments actually ship.
