Binance Welcomes Sign (SIGN) With Retroactive Airdrops for BNB Holders
Binance has officially introduced Sign (SIGN) as the 16th project featured on its HODLer Airdrops page, with trading set to begin on April 28, 2025 at 11:00 (UTC). The listing follows a retroactive airdrop of 200 million SIGN tokens to eligible users who subscribed BNB to Simple Earn or On-Chain Yields between April 15 and April 19.
SIGN will be available for trading against USDT, USDC, BNB, FDUSD, and TRY, and carries a Seed Tag due to its early-stage status. Spot Algo Orders, Trading Bots, and Copy Trading features will also be enabled progressively after the listing.
The airdrop represents 2% of SIGN’s total supply of 10 billion tokens, while another 1.5% is set aside for marketing initiatives beginning three months post-listing. An estimated 12% of the total supply—1.2 billion SIGN tokens—will be circulating at launch.
What is Sign (SIGN)? A Real-World Infrastructure Project
Sign is more than a token. The project serves as global infrastructure for credential verification and token distribution, offering governments, developers, and enterprises a decentralized solution to verify digital identities, ownership, and contractual interactions.
The ecosystem includes:
- Sign Protocol, an omnichain attestation layer powering apps like EthSign and SignPass.
- TokenTable, a smart contract-based platform handling airdrops, vesting, and unlocks.
- EthSign, the first onchain e-signature app.
- SignPass, a blockchain-native identity system used for government and enterprise-grade verification.
Sign’s utility token, $SIGN, functions as a universal gas token, community incentive, and governance tool across all its services. Holders who stay aligned long-term can help shape ecosystem governance and direction.
Real-World Adoption and Ecosystem Growth
Few Web3 projects can claim real-world usage across national borders, but Sign is already powering digital infrastructure in the UAE, Thailand, and Sierra Leone. Expansion plans include over 20 countries such as Barbados and Singapore.
The numbers reflect traction:
- $15 million in revenue generated in 2024, surpassing capital raised.
- Sign Protocol adoption surged from 4,000 to 400,000 schemas and over 6 million attestations last year.
- TokenTable has distributed over $4 billion in tokens across 40 million+ wallets, handling large-scale airdrops and unlocks with both flexibility and security.
The growing traction has drawn in major investors, with Sign securing $14 million in 2022 under the lead of Sequoia Capital, followed by an additional $16 million from YZi Labs in 2025 — pushing total funding to $32 million.
How Binance Users Benefit From the Airdrop
To qualify for the SIGN airdrop, users must have subscribed BNB to Simple Earn (Flexible/Locked) or On-Chain Yields during the eligibility window. Binance uses hourly average balance snapshots taken at random intervals to calculate rewards.
Rewards are automatically distributed to users’ Spot Accounts within 24 hours of the airdrop announcement, requiring no additional user action. For example, airdrops on June 11, 2024, used snapshot data from June 1–7 as reference.
Participation is capped to ensure fairness. No single user can receive more than 4% of the total eligible distribution, regardless of how much BNB they hold. Some users—particularly those in restricted jurisdictions like the U.S., U.K., or Canada—are excluded from eligibility.
Binance Alpha, Trading Access, and Post-Listing Notes
Ahead of the official listing, SIGN can be traded on Binance Alpha beginning at 10:00 (UTC) on April 28. However, once spot trading is live, SIGN will be removed from Alpha. Users will still be able to transfer tokens from Alpha to their Spot Accounts for continued trading.
Binance has confirmed that no listing fee was charged for SIGN, aligning with its support for early-stage infrastructure projects.
A Token Engineered for Utility and Transparency
From an infrastructure perspective, Sign stands out for its highly modular, secure, and multi-chain architecture. For example, Sign Protocol supports ZK-proof-based attestations that allow users to prove identity traits (like age or nationality) without exposing personal data.
The TokenTable platform complements this by offering flexible distribution mechanisms:
- Unlocker for fully onchain vesting.
- Merkle-based solutions for gas-efficient hybrid drops.
- Signature-based systems for social media- or condition-based airdrops.
With over 7.5% of total SIGN supply dedicated to airdrops, including 5% via Binance, the project reinforces its commitment to decentralization and early community ownership.
As the crypto market eyes scalable real-world applications, Sign’s growing adoption in government services, identity systems, and token management could establish it as one of Web3’s core infrastructure providers. Binance’s backing via the HODLer Airdrop reflects growing institutional confidence in the project’s mission and utility.
