Sign Protocol, originally launched as EthSign in 2020 and rebranded in 2024, is a decentralized platform focused on enabling secure, cross-chain attestations for Web3 applications. Operating on Ethereum, Binance Smart Chain (BSC), and Base, Sign facilitates verified on-chain identities, digital agreements, and token distribution. Its flagship products include TokenTable, a one-click token management platform for airdrops and unlocks, and systems for on-chain residency verification and programmable trust. The $SIGN token, launched on April 28, 2025, with a total supply of 10 billion and an initial circulating supply of 1.2 billion, is used for attestation fees, rewarding network participants, and community governance.
Sign powers real-world use cases, including national digital ID systems in the UAE, Thailand, and Sierra Leone, with plans to expand to over 20 countries, such as Barbados and Singapore. TokenTable has distributed over $4 billion in tokens to 40 million+ wallets, processing 6 million attestations across 400,000 schemas.
The protocol’s mainnet launched on April 28, 2025, alongside listings on Binance, Bitget, and MEXC, with trading pairs like SIGN/USDT. Sign raised $32 million in funding ($12M seed in 2022, $14M in 2023 led by Sequoia Capital, and $16M in 2025 led by YZi Labs). Sign aims to build trust infrastructure for Web3, competing with projects like Chainlink’s CCIP, but faces challenges in sustaining adoption and managing token supply.
Sign’s uniqueness lies in its omni-chain attestation system, enabling seamless verification of identities, credentials, and documents across blockchains without intermediaries. TokenTable simplifies airdrop and token unlock processes, while real-world adoption in national digital ID systems (e.g., UAE, Thailand) sets it apart. Its focus on programmable trust and developer-friendly APIs enhances Web3 interoperability.
The founders of Sign are anonymous. No specific individuals are publicly named as founders, though the project is backed by high-profile investors and claims support from figures like Changpeng Zhao (CZ).
Sign raised $32 million across three rounds: a $12 million seed round in 2022 led by Sequoia Capital and Circle Ventures, a $14 million round in 2023 led by Sequoia, and a $16 million round in 2025 led by YZi Labs (formerly Binance Labs). Other investors include Hack VC, Amber Group, and Altos Ventures.
