In an exciting development for Binance users, many woke up one morning to find unexpected free cryptocurrency tokens in their accounts as a reward for holding and staking their Binance Coin (BNB). This surprise came after Binance’s announcement of a retroactive airdrop for the Euler (EUL) token on October 13, 2025. This unique initiative captured the attention of both dedicated BNB holders and casual investors by rewarding users for their past engagement rather than through typical promotional events.
The retroactive nature of this airdrop marked a significant shift in how loyalty is acknowledged in the decentralized finance (DeFi) space. Unlike conventional campaigns that often require users to engage in new activities, Binance directly rewarded those who had previously staked or locked their BNB between October 4 and October 6, 2025. By recognizing prior transactions with tangible rewards, the approach highlighted a growing trend in DeFi to foster user loyalty.
Binance unveiled Euler (EUL) as part of its HODLer Airdrop Program, designed to incentivize BNB holders who consistently engage in staking via platforms like Simple Earn or On-Chain Yields. A total of 543,657 EUL tokens—representing 2% of the total supply—were distributed based on hourly random snapshots of user balances during the eligibility period. The initiative featured safeguards to ensure fairness: no participant could earn more than four times the average user’s share, and only genuinely staked BNB was considered, excluding tokens used for loans.
The launch of EUL trading commenced on the same day as the airdrop, enabling multiple trading pairs, including USDT, USDC, and BNB. In warning users of potential volatility, Binance also introduced a Seed Tag for EUL trading.
Euler itself is portrayed as a comprehensive DeFi Super App, integrating services like lending and trading into a user-friendly platform. This dual benefit of promoting user engagement through token rewards alongside elevating the visibility of the EUL project showcases a strategic move by Binance to solidify its position amidst a competitive market environment.
Responses from the crypto community regarding the EUL airdrop have been overwhelmingly positive, with many users expressing their surprise and excitement at receiving what they termed “free money for being loyal.” However, the exclusion of users from certain countries, such as the United States and the United Kingdom, due to regulatory implications has drawn criticism. Detractors assert that to foster global engagement, Binance needs to enhance the inclusivity of such initiatives.
Despite the criticisms, the successful rollout of the EUL airdrop signals a potential shift in how crypto platforms reward their users. By combining the stability of staking with the excitement of unexpected rewards, Binance is not only increasing user retention but also creating an environment that encourages continued participation. Market analysts suggest this model could lead to a surge in BNB staking activity and a growing expectation among users for similar surprises in the evolving DeFi landscape.
The introduction of retroactive rewards appears to redefine traditional engagement strategies, merging finance, technology, and innovative incentives. If this approach gains traction, it has the potential to transform user experiences across digital platforms, turning passive actions into exciting opportunities for growth and discovery.
