Sign Protocol is an omni-chain attestation protocol that brings verifiable trust to blockchain and real-world ecosystems. It allows users and organizations to create secure, blockchain-based attestations for claims, actions, and credentials.
With the launch of the $SIGN token and its initial airdrop, Sign Protocol is laying the foundation for a decentralized future of verifiable authenticity. This article covers what Sign Protocol is, how it works, the $SIGN tokenomics, airdrop participation details, key dates, and what's ahead for the project.
What Is Sign Protocol ($SIGN)?
Source: Sign Protocol X
Sign Protocol is building the foundation for decentralized verifiable trust, allowing users, apps, and enterprises to create secure attestations across multiple blockchain networks.
Instead of relying on centralized authorities, Sign Protocol enables users to independently verify claims, actions, and credentials using digital signatures, decentralized infrastructure, and modern cryptographic techniques.
The project was developed by the team behind EthSign, a Web3 e-signature platform for legally binding agreements, and TokenTable, a suite of smart contract tools for token distribution and unlocking. Together, these products reflect the team's long-standing commitment to improving authenticity, trust, and usability across decentralized systems.
Key Features of Sign Protocol
• Schema Registry: Provides standardized data structures for creating and verifying attestations.
• Effective Attestations: Introduces a framework prioritizing verifiability, relevancy, insightfulness, and universality.
• Decentralized and Open Architecture: Operates independently of any specific blockchain and encourages open public contributions.
• Attestation Layer and Infrastructure Layer: Serves as foundational trust infrastructure for applications and services.
• Focus on Simplicity and Accessibility: Guided by the principle of "Keep It Simple, Signer," ensuring attestation processes are intuitive and user-friendly.
By offering a flexible, chain-agnostic foundation for verifiable claims, Sign Protocol aims to become a core building block for trust across decentralized applications and real-world use cases.
How Does Sign Protocol Work?

Sign Protocol enables users to create verifiable attestations that are secure, standardized, and decentralized across multiple blockchains. Its system is built on a few core components:
• Schemas and Schema Registry: Schemas define the structure of attestations, making them clear and standardized. The Schema Registry stores reusable schemas and provides guidelines for creating new ones.
• Effective Attestations (e/att): A new design philosophy that emphasizes verifiability, relevancy, insightfulness, and universality. This ensures that attestations are provable, meaningful, and interoperable across different platforms.
• Omni-chain Support: Sign Protocol operates independently of any one blockchain, enabling attestations to be created and verified across Ethereum, Solana, TON, and EVM-based environments.
• Open Contributions: Both developers and non-developers are encouraged to contribute, through building integrations, offering feedback, or creating content. No-code tools are also planned to make participation even more accessible.
Through this structure, Sign Protocol provides a decentralized, flexible way to create and manage proofs of trust, moving beyond traditional reliance on centralized authorities.
