What is SIGN?
Global Infrastructure for Credential Verification & Token
Distribution
One omni-chain protocol + product suite that lets governments, enterprises, and Web3 builders verify any credential and distribute any token on-chain with bank-grade security and global interoperability.
Sign is building global infrastructure for credential verification and token distribution:
Sign Protocol: An omni-chain attestation protocol that powers digital public infrastructure for governments and functions as a foundational layer for decentralized apps — verifying identities, ownership proofs, and contracts.
TokenTable: A smart contract-based platform for token distribution, including airdrops, vesting, and unlocks.
SIGN is a native utility token and is used in the following functions:
Universal Utility: $SIGN powers all Sign protocols, applications, and ecosystem initiatives as the backbone of its onchain infrastructure.
Global Community Currency: Community can earn stake, spend, and create new utilities around $SIGN, making it the heartbeat of our economic and social layers.
Holding for Alignment: $SIGN holders who exemplify long-term commitment and active participation can shape the strategic direction of the ecosystem in the long run.
Sign Protocol is the infrastructure that powers the following applications:
EthSign, the first onchain e-signature dApp
TokenTable, the leading token distribution platform
SignPass, the onchain identity registration and verification system
Sign has raised a total of 32 Million USD.
Sign raised 14 million USD in 2022 through a seed round led by three units of Sequoia Capital (US, China, India & SEA).
Sign raised 16 million USD in 2025, through a Series A round led by YZi Labs.
Project overview:
Sign is the global infrastructure for credential verification and token distribution.
Project mission:
Sign aims to bring trust to trustless networks and drive for the mass adoption of blockchain technology through revolutionizing information verification and token distribution, utilizing blockchain as a super-sovereign database, and building a decentralized and sustainable community.
Project value proposition
Sign provides a universal protocol and application suite to make all digital data globally verifiable. By combining decentralized identity, on-chain attestations, and smart distribution systems, Sign empowers users, enterprises, and governments to verify credentials, ownership, and actions transparently and securely.
Project Key Highlights:
Real World Adoption: Sign is powering national-level digital infrastructure. Sign‘s product is live in the UAE, Thailand and Sierra Leone, with active expansion into 20+ countries including Barbados and Singapore, paving the way for super-sovereign infrastructure on-chain.
Revenue Milestone: Generated $15M in revenue in 2024, exceeding all capital raised. This validates strong product-market fit and positions Sign as one of the few revenue-positive Web3 infrastructure providers.
Usage & Ecosystem Growth: Sign Protocol saw schema adoption grow from 4,000 to 400,000, and attestations from 685K to 6M+ in 2024. TokenTable has distributed over $4B in tokens to 40M+ wallets, handling token airdrops, unlocks, and OTC trades with security and scale.
Global Cultural Community: The Orange Dynasty is uniting builders from across the world under a distinct symbolic identity and shared vision for money, freedom and integrity.
Backed by Global Tier-1 Investors: Raised $32M from Sequoia Capital (US, China, India & SEA), YZi Labs and other renown institutions and angel investors, reflecting global confidence in Sign’s long-term potential.
Existing Products:
Sign Protocol, the omni-chain attestation protocol, is the infrastructure that powers all Sign ecosystem applications.
TokenTable, the leading token distribution platform, offers unique social and identity verification features using onchain verification and smart contract that streamlines mass airdrop distribution.
EthSign, the first onchain e-signature dApp, enables users to sign and verify digital signatures while having their signed documents stored permanently onchain.
SignPass, the onchain identity registration and verification system, aims to streamline the administrative processes from sovereign governments to local organizations using blockchain technology.
Technical Infrastructure:
Sign Protocol achieves omnichain coverage by leveraging a combination of native public multichain deployment, native sovereign blockchain deployment, Arweave fallback deployment, and a high performance indexer, SignScan, to tie it all together.
When native smart contract interoperability is required, users can opt to utilize the Sign Protocol deployment local to their blockchain.
When cost-effectiveness is prioritized and native smart contract interoperability is not required, users can opt to utilize the Sign Protocol Arweave deployment which also supports mixing different identity providers from all blockchain VMs as well as Web2 systems.
SignScan provides an easily accessible and performant explorer and various indexing APIs for users and developers to query and view their records freely.
Sign Protocol utilizes both asymmetrical encryption and zero-knowledge proofs to redact or obfuscate sensitive information, making records publicly auditable or provable without compromising security. For example, users can prove their country of residence or age by scanning their passport with their phones and submitting a zero-knowledge proof without their passport data ever leaving their device. Such proofs can be utilized by a schema hook, which restricts attestation submissions unless certain criteria are met.
TokenTable is the swiss army knife of token distributions, covering all use cases ranging from investor and team vesting to social media gated multichain airdrops, available on EVM, Starknet, Solana, TON, and Move VM. This is made possible by different underlying architectures:
Unlocker: A fully onchain and trustless token unlocking solution, allowing for freely configurable unlocking schedules and extensible via hooks.
Merkle-based distributor: A hybrid token unlocking and airdrop solution, allowing for more flexibility and gas efficiency than the Unlocker.
Signature-based distributor: A centralized token airdrop solution, allowing for the most amount of flexibility and supporting more complex airdrop criteria such as social media engagement or any custom logic provided by the airdrop client.
Introducing Binance HODLer Airdrops
Binance HODLer Airdrops is a program that rewards BNB holders with token airdrops based on historical snapshots of their BNB balances. By subscribing BNB to Simple Earn, users are automatically eligible for HODLer Airdrops (as well as Launchpool and Megadrop rewards). By subscribing BNB to On-Chain Yields, users are automatically eligible for HODLer Airdrops and Launchpool rewards.
Unlike other earning methods that require ongoing actions, HODLer Airdrops reward users retroactively, offering a simple way to earn additional tokens. By subscribing BNB to Simple Earn products and/or On-Chain Yields, users can automatically qualify for token rewards.
How to Benefit from HODLer Airdrops
Head to [Earn] and search for BNB.
Subscribe to Simple Earn (Flexible and/or Locked) and/or On-Chain Yields products with your BNB holdings.
Snapshots of user balances and total pool balances will be taken multiple times at any point of time each hour to get users’ hourly average balances in Simple Earn (Flexible and/or Locked) and/or On-Chain Yields products. Binance will use historical snapshots of user balances at random periods after this announcement to calculate user rewards.
For example, reward calculation for HODLer Airdrops on 2024-06-11 may use snapshots of user balances between 2024-06-01 to 2024-06-07 as reference.
Eligible users will receive HODLer Airdrops rewards in their Spot Accounts within 24 hours after the HODLer Airdrops is announced.
Sign (SIGN), a global infrastructure for credential verification and token distributions. Users who subscribed their BNB to Simple Earn (Flexible and/or Locked) and/or On-Chain Yields products from 2025-04-15 00:00 (UTC) to 2025-04-19 23:59 (UTC) will get the airdrops distribution. The HODLer Airdrops information is estimated to be available in 12 hours, and the new token will be distributed to users’ Spot Accounts at least 1 hour before trading starts.
Binance will then list SIGN at 2025-04-28 11:00 (UTC) and open trading against USDT, USDC, BNB, FDUSD, and TRY pairs. The seed tag will be applied to SIGN. Users can start depositing SIGN in 1 hour after this announcement.
*Please note that SIGN will be available on Binance Alpha and can be traded on Binance Alpha from 2025-04-28 10:00 (UTC), but SIGN will no longer be showcased on Binance Alpha after spot trading opens.
