Sign Protocol is building something deeper than just another Web3 tool — it’s laying the foundation for digital trust.
At its core, Sign is an omni-chain attestation protocol designed to support digital public infrastructure. It enables governments, applications, and users to verify identities, prove ownership, and validate agreements — all onchain, without relying on centralized intermediaries.
On top of this foundation, products like EthSign bring legally binding e-signatures to the blockchain, TokenTable simplifies token distribution through smart contracts, and SignPass introduces a new model for onchain identity verification.
The ecosystem is powered by $SIGN, which acts as more than just a token. It fuels protocol activity, connects applications, and enables participation across the network. From staking and spending to community-driven utility creation, $SIGN plays a central role in both the economic and social layers of the ecosystem.
Long-term holders aren’t just passive participants — they contribute to shaping the direction of the network itself, aligning incentives between builders and users.
Backed by strong institutional support, Sign has raised a total of $32 million. Its early growth was fueled by a $14M seed round led by multiple branches of Sequoia Capital, followed by a $16M Series A led by YZi Labs in 2025.
What Sign is really building isn’t just infrastructure — it’s a system where trust becomes verifiable, portable, and owned by the userm
