Why is decentralized certification needed?
As the blockchain ecosystem becomes increasingly diverse, traditional centralized verification methods of Web2 can no longer meet the needs for cross-chain interoperability: information fragmentation, low verification efficiency, and lack of trust have become key pain points.@Sign Official The SIGN Protocol proposes the vision of 'trust stored on-chain, chain trust intercommunication' and is committed to reshaping the digital trust structure.
What is the SIGN Protocol?
SIGN Protocol is the world's first omni-chain attestation protocol, supporting structured certification and verification across multiple chains such as Ethereum, Solana, TON, Base, Starknet, and Move-based networks.
Core Functions
Use Schema Registry to standardize data formats, ensuring consistency and compatibility in certification.
Providing flexible data storage methods: pure on-chain storage, Arweave off-chain storage, and hybrid storage to balance security and cost.
Possesses cross-chain verification capabilities, allowing certifications on one chain to be queried and verified by other chains.
Integration of products such as legally valid signatures (EthSign) and decentralized identity (SignPass) to form a complete ecological closed loop.
The ecological product matrix of SIGN
SIGN is not only a protocol but also builds a diversified, implementation-oriented product system.
EthSign: an on-chain electronic signature platform providing a user experience similar to DocuSign, but with encrypted storage, security, traceability, and compliance.
TokenTable: a smart contract-driven token distribution tool, including Airdrop Pro (million-level user airdrops), Airdrop Lite, Unlocker, and other multifunctional modules.
Schema Registry: a certification template library that defines data structure templates to facilitate developers in creating compatible and composable systems.
SignScan: a certification browser and API query tool for easy retrieval by users and developers.
SignPass (on-chain identity registration verification system) and Sign Profile (integrating social accounts, sovereign IDs, domain names, World IDs, etc., with on-chain identities).
Implementation and data performance
2024: Processing over 6 million attestations and distributing over $4 billion in tokens to more than 40 million wallets through TokenTable.
The number of Schema registrations skyrocketed from 4,000 to 400,000, and attestations grew from 685K to over 6M.
2024 revenue approximately $15M, exceeding the financing scale, reflecting strong product-market fit.
Global layout: already landed offline in the UAE, Thailand, and Sierra Leone, and expanded to over 20 countries including Barbados and Singapore.
$SIGN (SIGN Token)
$SIGN It is the ecosystem's native token, used for paying fees, governance voting, and incentivizing users across all business modules.
The total supply cap is 1 billion tokens, with an initial circulation of 12%, or 120 million tokens; other allocations are as follows: community rewards 40%, investors 20%, team 10%, foundation 10%, ecological development 10%.
TGE to be held in April 2025, including airdrop for Binance token holders and opening of trading.
Completed financing: $14M seed round in 2022 (led by Sequoia Capital), $16M Series A in 2025 (led by YZi Labs), totaling nearly $32M.
What is the charm? The core attraction of SIGN?
Real cross-chain certification capability: breaking down inter-chain barriers, unified verification system is more convenient and scalable.
Strong product ecosystem practicality: full scenario coverage from signing to distribution to identity management.
Landing verification and rapid growth: millions of application scenarios + government cooperation + market value growth.
Clear economic model: transparent token distribution, sound community and governance mechanisms.
Equal emphasis on legal compliance and privacy protection: supports legally recognized signatures and zero-knowledge privacy proofs (e.g., TLSNotary).
Global strategic cooperation is being promoted persistently: not only has technological potential but also possesses social foundational credibility.
