Why you should listen

The core offering of Sign Global is built around the Sign Protocol — a multi-chain attestation framework that allows users to submit, verify and manage on-chain attestations of real-world or digital claims. This is an infrastructure layer for trust, identity and verification across “Web 3” ecosystems, designed to reduce reliance on centralised authorities by making attestations transparent and accessible. 

In addition to the protocol itself, Sign Global offers tools and services built atop that infrastructure. For example, they highlight developer-friendly integrations that span multiple blockchain networks (Solana, Aptos, TON, others), and features including “TokenTable” and “EthSign” (contract signing tools) as components of their stack. 

Finally, from a business reach perspective, Sign served over 50 million users and facilitated more than US$2 billion in digital-asset transactions via its platform.
