SIGN: The Omni-Chain Attestation Protocol that Transforms Digital Verification in Web3

What is SIGN and Why Does It Matter in the Blockchain Ecosystem?

In the decentralized Web3 ecosystem, information verification remains one of the biggest challenges. While blockchain technology promises transparency and immutability, the current reality shows severe fragmentation: verified data on one chain remains inaccessible on another, users must repeat verification processes on each blockchain, and there is no unified standard for digital attestations.

The SIGN Protocol emerges as the world’s first truly multi-chain attestation solution, allowing users and companies to create, verify, and manage secure attestations across multiple blockchains including Ethereum, Solana, and TON. $SIGN, the native token of the ecosystem, powers the entire infrastructure while providing governance rights to holders.

The Product Ecosystem: How the SIGN Protocol Works in Practice

EthSign: Legally Valid Document Signing

EthSign connects real-world legal agreements with decentralized identities, offering the same user experience as traditional electronic signature platforms but with enhanced security via blockchain. Users can upload documents, define signature fields, invite co-signers, and track the full lifecycle of the agreement with immutable cryptographic verification.

Unlike purely technical solutions, EthSign ensures signatures are legally binding in jurisdictions with technology-neutral legislation, including the United States, China, and Australia.

TokenTable: Token Distribution Infrastructure

TokenTable is a set of tools for on-chain token distribution and management, having processed over $130 million in distributions for more than 30 million users. It includes:

• Airdrop Pro: Mass token distribution across EVM, TON, and Solana networks simultaneously
• Airdrop Lite: Optimized version for smaller distributions up to 100,000 users
• Unlocker: Temporary unlocking system with customizable schedules and fraud protection

Schema Registry: Reusable Attestation Standards

Functions as a central repository for attestation schemas, providing standardized templates that ensure compatibility and composability across the ecosystem. Developers can create attestations that work seamlessly across multiple contexts and blockchains.

SignScan: Attestation Explorer and Verifier

An intuitive interface that allows users to explore and verify attestations. It offers visual exploration for non-technical users as well as powerful REST and GraphQL APIs for developers to query real-time data.

Critical Problems Resolved by SIGN

1. Fragmentation of Trust

The current web relies on centralized third parties to verify information, creating isolated silos. SIGN establishes a unified verification standard that works cross-chain.

2. Barriers Between Chains

Before SIGN, verification on one blockchain was useless on another. Users with multiple identities across different networks had to repeat verification processes constantly.

3. Process Accessibility

Traditional verification methods are complex. SIGN radically simplifies these processes with a user-centric approach.

4. Document Authenticity

In a world of deepfakes and data manipulation, SIGN guarantees authenticity through permanent and immutable cryptography.

Competitive Advantages of the SIGN Protocol

Omni-Chain Support

Unlike competitors limited to single ecosystems, SIGN operates as a truly multi-chain protocol, eliminating the fragmentation affecting other systems.

Proven Use Cases in Production

• EthSign: Established platform for digital document signing with blockchain verification
• TokenTable: Token distributor for major projects, demonstrating real problem-solving capacity

Flexible Storage Architecture

Users can choose between:

• On-chain full: Maximum security and transparency
• Arweave: Permanent and immutable storage
• Hybrid: Balances efficiency and security

Built-in Legal Compliance

Incorporates legal validity into the protocol design, not just as a technical feature.

Open Protocol Philosophy

Makes attestation technology accessible to everyone, not just companies or exclusive networks, democratizing digital verification.

The Evolution of SIGN: From Document Signing to Universal Attestation

The SIGN Protocol evolved from EthSign, which initially focused on bringing document signing to the blockchain. As it gained traction, the team recognized that signing was just one application of a broader need: verifiable attestations across the entire Web3 ecosystem.

Key milestones include:

• Launch of EthSign as a blockchain-based signing platform
• Development of TokenTable for token distribution with verification capabilities
• Expansion into the SIGN Protocol to address broader attestation needs
• Implementation of cross-chain verification supporting multiple blockchains

Future Vision: Four Layers of the Attestation Ecosystem

SIGN envisions building a comprehensive ecosystem with four interconnected layers:

Trust Layer: Infrastructure and social institutions providing the foundation
Application Layer: Apps and services utilizing verified trust
Infrastructure Layer: Attestation data processing for applications
Attestation Layer: Manages attestations and their component elements
