Recent Developments of Sign Protocol

On March 4th, the full-chain authentication protocol Sign Protocol announced updates regarding the SIGN token allocation and the Soulbound Token (SBT) incentive mechanism, while clarifying that the Token Generation Event (TGE) has not yet occurred. The SBTs are divided into four tiers, and the team has decided to remove the previous plan of reducing the issuance quantity per round, instead increasing the frequency and amount of distribution. The team emphasized that SIGN is not only a reward but also an incentive for users to build their own platforms.

Introduction to Sign Protocol

Sign Protocol is a full-chain authentication protocol that enables the verification of all digital information (such as ownership, identity, and certificates) on-chain, aiming to serve everyone. It provides a suite of tools, infrastructure, and standards to create a future where all assertions and statements about the network and the surrounding world are driven by verifiable authentication. This is achieved through modern technologies like decentralized blockchains and data storage solutions, as well as new technologies such as zero-knowledge cryptography and digital signatures.

Sign’s “Four Pillars” System

To date, the Sign team has launched multiple services to meet diverse user needs, evolving from a single electronic signature tool to exploring a "trust layer on-chain":

• Sign Protocol: In 2024, EthSign rebranded as Sign with its core component, Schema, a data structure and configuration for creating clear and verifiable proofs, aiming to build a cross-chain trust layer. It supports proof creation and verification on Ethereum, Polygon, Solana, Ton, Aptos, and more.

• TokenTable: Launched at the end of 2022 to early 2023, TokenTable is a multi-chain Web3 token management platform that has distributed tokens for over 200 projects (e.g., Starknet, ZetaChain) and is an extension of the EthSign ecosystem.

• SignPass: Based on Sign Protocol’s on-chain authentication technology, SignPass provides users with verifiable on-chain identities compatible with existing passport systems and links to unique QR codes recorded on the blockchain.

• EthSign: A decentralized electronic agreement signing platform offering the same functionality, user experience, and legal validity as traditional electronic signatures.

Sign Team

EthSign (now Sign) was founded in 2020 in Singapore by Xin Yan (CEO), Potter Li, and Jack Xu. Potter Li, co-founder of EthSign, previously interned at Morgan Stanley and Fundamental Labs. Jack Xu, co-founder and CTO of EthSign, is an alumnus of the 0G ecosystem and Story Protocol. Xin Yan, co-founder and CEO of EthSign, has extensive experience in blockchain and decentralized storage, providing a solid foundation for the project's long-term development.

Sign Financing

Sign, formerly known as EthSign, underwent a complete rebranding in 2024. It has secured multiple funding rounds:

• In July 2021, Sign raised a $650,000 seed round led by Draper Associates.

• In March 2022, Sign secured a $12 million round led by Sequoia Capital and Mirana Ventures.

• In February 2023, Sign received undisclosed funding from Animoca Brands.

• In January 2025, Sign raised $16 million led by Yzi Labs, with participation from Hack VC, Amber Group, and Altos Ventures.

Sign Summary

Sign aims to become the universal trust layer of the Web3 ecosystem. Moving forward, it needs to further expand its ecosystem partnerships to achieve its vision of a global trust layer where users can sign anything on-chain. With tools and standards like TokenTable, SignPass, and Sign Protocol, it is building an interconnected ecosystem.
