$SIGN is the native utility token of the Sign ecosystem—an omni‑chain attestation protocol and automated token‑distribution suite that spans Ethereum, BNB Smart Chain, Base, Starknet, Solana, TON, and Move‑based networks. As the backbone of Sign Protocol, TokenTable, and SignPass, $SIGN powers on‑chain credential verification, mass airdrops, vesting schedules, and unlock mechanisms for projects and institutions.
