On January 28, 2025, YZi Labs, the rebranded division of Binance Labs, announced an investment in Sign Protocol, a blockchain-based token airdrop service. The investment amounts to $16 million, supported by Binance founder Changpeng Zhao.
What Is Sign Protocol?
Sign Protocol is an omni-chain attestation protocol that enables users to verify and attest information on blockchain. It simplifies token distribution infrastructure for humans and AI agents, leveraging decentralized technologies and zero-knowledge cryptography. Founded in 2021, the project has become a leader in the token distribution sector, trusted by over 200 projects, including Starknet, Movement, and ZetaChain.
How Does Sign Protocol Work?
Sign Protocol offers a scalable platform for verifying claims on blockchain. The protocol supports multiple blockchains, including EVM chains, Starknet, Solana, and TON. It utilizes both on-chain and off-chain data storage modes, allowing the selection of the most cost-effective method. The system supports zero-knowledge proofs and digital signatures for consent verification, making it interoperable with different chains and algorithms.
Future Plans of Sign Protocol
With fresh investments, Sign Protocol plans to expand partnerships with centralized exchanges and governments, integrate AI-driven applications, and launch its native token. This funding will help strengthen its ecosystem and continue blockchain adoption through secure token distribution and credential verification.
With significant investment, Sign Protocol aims to enhance token distribution processes and integrate Web3 technologies, a crucial step towards widespread blockchain adoption.
