What Is the Zksync Airdrop?
The Zksync airdrop represents a significant token distribution event where ZK tokens were allocated to early users and contributors of the platform. This initiative took place following the one-year anniversary of the Zksync Era mainnet launch.
Overview of Zksync and Its Ecosystem
Zksync is a Layer 2 scaling solution built on Ethereum that utilizes zero-knowledge rollup technology. This technology helps improve transaction speeds and reduce gas fees while maintaining the security of the Ethereum network.
Zksync operates through two main components:
- Zksync Lite: The original version that focused on transfers and swaps
- Zksync Era: The expanded version that supports smart contracts and dApps
The ecosystem has grown significantly since its launch, attracting developers and users seeking more efficient blockchain interactions. Zksync’s technology aggregates multiple transactions into a single proof that is then verified on Ethereum, creating a more scalable system while inheriting Ethereum’s security guarantees.
Purpose of the Zksync Airdrop
The Zksync airdrop allocated 17.5% of the total ZK token supply to reward early adopters and contributors. The distribution followed a snapshot taken on March 24, 2024, at 00:00 UTC, capturing user activity on both Zksync Lite and Era networks.
The airdrop served multiple strategic purposes:
- Community Reward: Recognizing early supporters who helped test and grow the network
- Decentralized Governance: Distributing tokens to enable community participation in future decisions
- Ecosystem Growth: Encouraging broader adoption and continued engagement
The distribution was divided between two main categories:
- 89% to active users based on their transaction history
- 11% to contributors who helped develop or promote the platform
Significance for Ethereum Users
For Ethereum users, the Zksync airdrop represents more than just free tokens. It signals the growing importance of Layer 2 solutions in addressing Ethereum’s scalability challenges.
Users who received ZK tokens gained:
- Governance rights in one of the leading Layer 2 ecosystems
- Financial benefits from early adoption
- Reduced transaction costs compared to Ethereum mainnet
The airdrop also demonstrated how Layer 2 protocols are becoming crucial infrastructure in the Ethereum ecosystem. By rewarding users who bridged assets to Zksync and performed transactions there, the airdrop encouraged the behavioral shift needed for Ethereum to scale effectively.
Many Ethereum users now view participation in promising Layer 2 networks as both a practical way to reduce fees and a potential investment in future airdrops.
Eligibility and Requirements
The ZKsync airdrop distributed 3.675 billion ZK tokens (17.5% of total supply) to eligible participants based on specific criteria. Nearly 700,000 wallets qualified for this token distribution with no vesting or lock-up periods.
Who Qualified for the Airdrop
Users who demonstrated activity on both ZKsync Lite and ZKsync Era networks were prioritized for the airdrop. The eligibility assessment followed a four-step sequential process that evaluated user engagement within the ecosystem.
Key qualification factors included:
- Transaction history on ZKsync networks
- Minimum threshold of activity (frequency and volume of transactions)
- Participation in ecosystem campaigns
- Liquidity provision to ZKsync protocols
Users who consistently used the network for transfers, swaps, and other on-chain activities had higher chances of qualification. Those who deposited funds into ZKsync-based DeFi protocols also improved their eligibility status.
Early adopters who supported the network during its development phases received special consideration.
Snapshot Dates and Criteria
The official ZKsync airdrop snapshot occurred on March 24, 2024, at 0:00 UTC. This date marked the one-year anniversary of the ZKsync Era mainnet launch.
The snapshot captured user activity data including:
- Transaction count across ZKsync networks
- Total volume of transactions processed
- Duration of engagement with the platform
- Diversity of protocols used within the ecosystem
Activity both before and after the snapshot date was considered in the eligibility determination process. The team evaluated user behavior patterns rather than one-time large transactions to prevent airdrop farming.
Users who participated in multiple aspects of the ecosystem (trading, staking, providing liquidity) received higher allocations of ZK tokens.
How to Claim ZK Tokens
Eligible users can claim their ZK tokens through a straightforward process on the official ZKsync platform. The claiming window opened following the token launch with specific timeframes for redemption.
The claiming process involves:
- Connecting the eligible wallet to the ZKsync claim portal
- Verifying ownership through a signature request
- Confirming the allocation amount displayed
- Initiating the claim transaction
- Receiving ZK tokens directly to the connected wallet
Unclaimed ZK tokens have a designated timeframe for redemption. After this period expires, unclaimed tokens may be redistributed to the ecosystem fund or community treasury.
Users should ensure they have sufficient ETH to cover gas fees for the claim transaction. The ZKsync team implemented security measures to protect user funds during the claiming process.
Airdrop Distribution and Tokenomics
The ZKsync airdrop represents a significant milestone with 17.5% of total ZK tokens being distributed to early users and contributors. This distribution follows a carefully planned structure that balances community rewards with long-term platform governance.
Details of Token Distribution
The ZKsync airdrop is scheduled to begin on June 17, 2025, through the official claim page at https://claim.zknation.io/. This page serves as both a checker and claim portal for eligible users.

These contracts have undergone thorough security audits to protect against potential vulnerabilities. The distribution contracts include anti-Sybil attack measures to prevent gaming of the system and ensure fair distribution.
Key features of the distribution contracts include:
- Time-locked vesting schedules for certain allocations
- Transparent verification of eligibility criteria
- Gas-efficient claim mechanisms
- Support for delegation of governance rights
Users can verify all transactions on-chain, maintaining the transparent ethos of the ZKsync ecosystem. The contract addresses will be published on official channels prior to the airdrop launch to help users verify legitimacy and avoid potential scams.
Security Measures and Incident Response
ZKsync’s $5 million token theft in June 2024 exposed critical security vulnerabilities in their airdrop system. The incident highlighted weaknesses in admin key management and contract functions that allowed attackers to steal unclaimed tokens.
Initial Security Measures
Before the incident, ZKsync implemented standard security protocols for their airdrop distribution. They used Merkle distributor contracts to manage token allocation and claims. These contracts allowed eligible users to claim their tokens while maintaining control over unclaimed assets.
The system relied on admin keys to manage these contracts and perform maintenance functions. ZKsync’s security team had established basic access controls and monitoring for suspicious activities.
However, these measures proved insufficient against sophisticated attackers. The security infrastructure lacked robust multi-signature requirements for administrative functions, leaving single points of failure that could be exploited.
Compromised Key and Admin Account
The attack began with the compromise of an admin key that controlled access to three specific ZK token Merkle distributor contracts. These contracts contained approximately $5 million worth of unclaimed airdrop tokens from the June 2024 distribution.
The security team detected the breach quickly and initiated incident response measures. They confirmed that only the airdrop contracts were affected, while user funds in the main protocol remained safe.
The Matter Labs team, along with the ZKsync Association and Foundation, launched an investigation immediately. They isolated the affected contracts to prevent further damage and began working on recovery options.
SweepUnclaimed() Function and Its Role
The attacker exploited the sweepUnclaimed() function within the Merkle distributor contracts. This function was designed to allow administrators to reclaim tokens that remained unclaimed after distribution periods ended.
When properly used, sweepUnclaimed() serves as a cleanup mechanism for airdrops. However, with the compromised admin key, the attacker could redirect these unclaimed tokens to their own wallet instead of returning them to the project treasury.
The security team has since announced plans to enhance their infrastructure by transitioning to multi-party computation (MPC) systems. This would eliminate single points of failure by requiring multiple authorized parties to approve administrative actions, making similar exploits much more difficult in the future.
Security Incident Analysis
The ZKsync airdrop security breach on April 15, 2025, resulted in approximately $5 million worth of tokens being stolen through a compromised administrative account. This significant incident affected unclaimed airdrop tokens but fortunately left user funds intact.
Timeline and Discovery of the Attack
On April 15, 2025, ZKsync team identified unusual activity within their airdrop distribution system. The security team noticed unauthorized minting of ZK tokens occurring through an administrative account. This discovery prompted an immediate investigation and emergency response.
The attack specifically targeted three airdrop distribution contracts that were under the control of the compromised admin account. Within hours of the initial breach, the hacker had successfully minted approximately $5 million worth of unclaimed airdrop tokens.
ZKsync quickly alerted the community about the incident through official channels. They immediately froze remaining distribution contracts to prevent further unauthorized token minting while their security team worked to address the vulnerability.
Investigation Report and Updates
The investigation revealed that the attacker gained access through a compromised administrative wallet with special privileges. This wallet had authorization to mint tokens intended for the airdrop distribution.
ZKsync published a detailed incident report on the same day, explaining that the breach was limited to unclaimed airdrop tokens. They confirmed that the core protocol remained secure and no smart contract vulnerabilities were exploited.
The security team worked with blockchain analytics firms to track the stolen tokens. They implemented additional security measures including multi-signature requirements for administrative functions and enhanced monitoring systems.
Regular updates were provided to the community throughout the investigation process. ZKsync collaborated with exchanges to flag and potentially freeze the stolen assets if they appeared on trading platforms.
Impact on User Funds and Stolen Tokens
The security breach affected approximately $5 million worth of unclaimed airdrop tokens. These were tokens reserved for users who had not yet claimed their airdrops, not tokens that were already in user wallets.
What was affected:
- Unclaimed airdrop tokens (~$5 million)
- Market confidence temporarily
- ZK token price (short-term volatility)
What remained secure:
- User funds in wallets
- Protocol infrastructure
- Already-claimed airdrop tokens
The incident created temporary market volatility as token prices fluctuated in response to the news. ZKsync assured users that they were exploring options for addressing the losses, including potentially reissuing tokens to affected users from company reserves.
The team implemented additional security protocols to prevent similar incidents in the future, focusing specifically on administrative account access controls and distribution contract security.
Community Response and Bounty Initiatives
The ZKsync community rallied quickly after the April 2025 airdrop exploit, showing both resilience and practical problem-solving. Their coordinated efforts focused on recovering the stolen funds while establishing better security measures for the future.
10% Bounty Proposal
Matter Labs and the ZKsync security council acted swiftly by offering the attacker a 10% bounty in exchange for returning the stolen tokens. This pragmatic approach proved effective when the hacker accepted the deal and returned nearly $5.7 million in stolen ZK tokens, keeping approximately $570,000 as the bounty payment.
The bounty negotiation occurred through on-chain messages that were transparent to the entire community. This public approach helped restore some confidence in the protocol despite the security breach.
Several community members initially questioned the 10% figure, suggesting it might set a problematic precedent, but most ultimately supported the practical solution that recovered 90% of the funds.
Community Governance Role
Community governance played a crucial role in the aftermath of the exploit. Token holders participated in emergency votes regarding the handling of the recovered tokens and future security measures.
A special governance forum was established where security experts from the community proposed improvements to ZKsync’s administrative access controls. These suggestions led to the implementation of new multi-signature requirements for sensitive contract functions.
The governance process demonstrated the value of decentralized decision-making during crises. Members voted to allocate a portion of treasury funds toward enhanced security audits and created a dedicated security committee with rotating community representatives.
Ongoing Support From Matter Labs
Matter Labs, the team behind ZKsync, maintained transparent communication throughout the incident. They published detailed technical explanations of the vulnerability and outlined specific steps to prevent similar exploits.
The team committed additional resources to security, hiring specialized auditors to review all airdrop-related contracts. They also established a permanent bug bounty program with clear reward tiers for different vulnerability severities.
Matter Labs hosted several community calls to address concerns and answer questions about the incident. These sessions helped rebuild trust and provided technical clarity about the isolated nature of the vulnerability, confirming that ZKsync’s core infrastructure remained secure.
Managing Unclaimed Tokens
Unclaimed tokens represent a significant security consideration in the ZKsync airdrop ecosystem. Recent events have highlighted the importance of proper management protocols for these tokens to prevent unauthorized access and potential exploitation.
Overview of Unclaimed ZK Tokens
Unclaimed ZK tokens from the ZKsync airdrop remain in the airdrop contract until they are claimed by eligible users. According to recent reports, these unclaimed tokens are added to the total mintable supply under the control of the ZKsync foundation.
In April 2025, the ZKsync network experienced a security breach where an attacker compromised an admin account. This allowed them to mint approximately $5 million worth of unclaimed airdrop tokens.
The incident specifically targeted the unclaimed tokens in the airdrop contract rather than user funds in personal wallets. This breach highlighted a critical vulnerability in how unclaimed tokens were managed and secured.
sweepunclaimed() and Recovery Mechanisms
The sweepunclaimed() function serves as a protocol mechanism to manage tokens that remain unclaimed after the airdrop period. This function allows authorized administrators to recover and reallocate unclaimed tokens for ecosystem initiatives.
Following the security incident, ZKsync implemented stronger key management protocols and additional authentication layers for administrative functions including the sweepunclaimed() mechanism.
For users who haven’t claimed their tokens yet, ZKsync provided a manual claim process. This allows legitimate recipients to still access their tokens even after the primary claim period has ended.
The ZKsync Token Assembly now oversees the reallocation of recovered unclaimed tokens. These funds are directed toward community development, ecosystem growth, and security enhancements rather than remaining vulnerable in the airdrop contract.
Future Outlook for Zksync and Airdrop Participants
The Zksync ecosystem stands at a pivotal moment following its 2024-2025 airdrop period. Participants and potential investors should watch for several key developments that will shape the platform’s trajectory through 2025 and beyond.
