Binance Adds Support for Sign (SIGN) with Retrospective Airdrops for BNB Holders

Binance has officially designated Sign (SIGN) as the 16th project in its HODLer Airdrops Program, with trading

Binance has added support for Sign (SIGN), the 16th project in its hotly anticipated HODLer Airdrops Program. The exchange will begin trading the token on April 28 at 11:00 (UTC).

The listing follows a recent announcement regarding a retroactive airdrop of 200 million SIGN tokens to eligible users who subscribed BNB to Simple Earn or On-Chain Yields.

The SIGN token will be available for trading against USDT, USDC, BNB, FDUSD, and TRY. It will also carry a Seed Tag due to its early-stage status. Moreover, Binance will be enabling Spot Algo Orders, Trading Bots, and Copy Trading features progressively after the listing.

The 200 million SIGN tokens being airdropped represent 2% of the total supply, which is 10 billion coins. An additional 1.5% will be allocated to market-making incentives three months after the listing. At launch, 12% of the circulating supply—which is equal to 1.2 billion SIGN tokens—will be made available.

What is Sign (SIGN)? An Infrastructure Project in Real Life

SIGN is more than a token—it serves as global infrastructure for decentralized identity and credential verification. The ecosystem includes:

The native token $SIGN acts as a universal gas token, a community incentive, and a governance tool for all services. Long-term token holders play a crucial role in influencing governance and the direction of the ecosystem.

SIGN Adoption & Global Ecosystem Growth

Rare early web3 projects have real-world use across international borders, yet SIGN is already the force behind digital infrastructure in the UAE, Thailand and Sierra Leone. There are also plans to expand to more than 20 countries, including Barbados and Singapore.

The numbers reflect traction:

The momentum has also attracted high-profile investors, Sign raised $14M in 2022 led by Sequoia Capital and another $16M by YZi Labs in 2025, bringing the funding total to $32M.

How Binance Users Benefit from the Sign Airdrop

To be eligible for the SIGN airdrop, you need to have staked BNB to either Simple Earn (Flexible/Locked) or On-Chain Yields during the campaign period. Binance calculates rewards using hourly average balance snapshots taken at random intervals.

The rewards will automatically come into your Spot Account within 24 hours after the airdrop announcement. Airdrops on June 11, 2024 used snapshot data from June 1–7 as the baseline that received the airdrop.

Each user is subject to a maximum reward cap to ensure fair distribution. No individual user can receive more than 4% of the total distribution, regardless of how much BNB they hold. A few users—specifically those in blocked countries such as the U.S. and the U.K. and Canadian individuals—are considered ineligible.

Sign Trading on Binance Alpha and Post-Listing Insights

SIGN will be available for early access trading on Binance Alpha at 10:00 (UTC) on April 28. After the official spot listing, Alpha trading will end, but users can transfer their tokens to Spot accounts.

Binance has announced that it did not charge a listing fee for SIGN, consistent with its backing of early stage infrastructure efforts.
