Amidst Ongoing Debates, Can ZKsync Still Become a Dark Horse in the Layer 2 Race?

The highly anticipated ZKsync airdrop allocation plan has been finalized. The ZKsync Association will conduct a one-time airdrop of 3.6 billion ZK tokens to early users and adopters of ZKsync next week, with 695,232 eligible wallets. The snapshot was taken on March 24, and community members can claim the airdrop from next week until January 3, 2025.

ZKsync is an Ethereum Layer 2 chain that uses zero-knowledge rollup (ZK rollup) technology to address Ethereum's current scalability issues. ZKsync aims to provide cheaper and faster transactions on the Ethereum blockchain and become a home for many popular Ethereum applications. If successful, we could see major decentralized exchanges and DeFi protocols expanding to the zkSync layer, allowing cryptocurrency users to access these tools at lower costs.

However, whether it's the earlier trademark dispute over the "zk" trademark by ZKsync's parent company or the current airdrop controversy, ZKsync has once again been thrust into the spotlight.

ZKsync in the Eye of the Storm

ZKsync is an Ethereum L2 solution launched by the Matter Labs team five years ago, using zero-knowledge proof technology to achieve efficient transaction verification. It has raised over $200 million to date. In 2020, ZKsync Lite 1.0 was officially launched. Subsequently, the Matter Labs team improved and optimized it, launching the ZKsync Era mainnet in 2022. This mainnet supports EVM, introduces account abstraction functionality, and is equipped with a complete set of development tools, attracting over 200 projects including Uniswap and 1inch to deploy on the ZKsync Era mainnet.

Previously, rumors circulated that Matter Labs, the development company behind ZKsync, had gone a step further in choosing ZK as the token name by filing trademark applications in nine countries, attempting to make "ZK" Matter Labs' exclusive intellectual property.

This angered the crypto industry. StarkWare, Algorand, Polygon, Polyhedra Network, Kakarot, and several other ZK projects jointly issued a statement condemning Matter Labs' actions.

On June 3, Matter Labs tweeted that after previous discussions, they decided to abandon all trademark applications for the term "ZK". The CEO of Matter Labs stated: "This wasn't an easy decision. It increases legal risks, but the fundamental purpose of ZK is to help humans change the way we collaborate, from 'don't be evil' to 'can't be evil', and I feel this is the right thing to do."

In recent days, ZKsync's airdrop criteria have also sparked community controversy. ZKsync checked every address that had transacted on ZKsync Era and ZKsync Lite according to eligibility criteria to identify genuine users who spent time seriously exploring ZKsync. However, many people found they came up empty-handed after checking their addresses.

As the airdrop is about to begin, phishing attacks may also increase. Here are some key security tips to help you avoid being phished when claiming the ZKsync airdrop:

Ensure you access ZKsync airdrop-related websites through official channels. Any unfamiliar links sent via email or private messages could be phishing sites, so be vigilant.

Check the authenticity of the URL. Before visiting a website, carefully check the spelling and domain name of the URL. Phishing sites often use URLs very similar to official websites to induce users to enter sensitive information.

Do not provide private keys, mnemonics, or any other personal sensitive information to claim the airdrop. If you receive any requests for this information, stop immediately.

ZKsync Ecosystem Security

On June 1, 2024, according to Beosin Alert monitoring, the Velocore project on both ZKsync and Linea chains was attacked multiple times by hackers, resulting in the theft of over ten types of tokens, with the stolen amount exceeding $6.8 million. Currently, the attacker has transferred the stolen funds to the Ethereum chain through cross-chain bridges and has exchanged all the funds for ETH. As of the time of writing, the attacker has transferred all ETH to Tornado.Cash.

Attacker address (ZKsync, Linea):


As the ZKsync ecosystem continues to develop and expand, ensuring its security becomes particularly important. As one of Ethereum's Layer 2 scaling solutions, ZKsync aims to provide more efficient transaction processing capabilities and lower transaction costs. However, with the increase in users and developers, security risks also arise.

In this context, security audits become crucial. Beosin, as a leading blockchain security company, has played a key role in safeguarding the ZKsync ecosystem, providing strong security assurance for projects on ZKsync.

Currently, Beosin has completed the audit of the SyncSwap project's launch protocol. The audit content includes code quality audit, contract logic and security audit, operational model audit, etc. The final audit found that the contract has an issue of excessive management privileges, where the contract owner can withdraw user-deposited assets from the contract before the project launch. The project team is acknowledged of this issue and has stated that they will use a multi-signature wallet to manage the project in the future.
