As a blockchain analyst, I’ve noticed that Ethereum, the go-to platform for building decentralized applications (DApps), is grappling with a major challenge: scalability. With more users hopping on board, transaction fees have surged to unprecedented levels, making it difficult for mainstream adoption. However, there’s a potential game-changer on the horizon called ZkSync. This innovative solution aims to tackle this issue while maintaining Ethereum’s robust security and decentralization features.
What is zkSync?
ZkSync represents a scalability approach for Ethereum blockchain through the implementation of zero knowledge rollups, referred to as ZK-rollups. This technology relies on zero-knowledge proofs (ZK-proofs), which is a cryptographic methodology, to process transactions outside the main Ethereum blockchain (layer 2 or L2). Despite being off-chain, it maintains Ethereum’s security properties from layer 1 or the primary blockchain.
As a crypto investor, I’m excited to share that ZkSync is the creation of Matter Labs, a dynamic team composed of dedicated blockchain engineers and entrepreneurs. Led by Alex Gluchowski, co-founder and CEO of Matter Labs, this prominent figure in the Ethereum community has made significant strides in scaling solutions. Our team’s unyielding technical expertise and commitment to decentralization are pivotal factors driving ZkSync’s impressive achievements.
ZkSync’s advancement is significantly boosted by a prestigious group of investors, including Andreessen Horowitz, Sequoia Capital, and Balaji Srinivasan. With their support, zkSync gains essential financial resources and valuable strategic direction, fueling its robust growth path.
Here’s how zkSync works:
- zkSync bundles multiple transactions into a single batch, significantly reducing gas fees per transaction.
- Transactions are processed efficiently on the layer 2, alleviating the burden on the main Ethereum network.
- zkSync generates cryptographic proofs (ZK-proofs) proving the validity of the processed transactions without revealing their details. These proofs are then submitted back to the Ethereum mainnet for verification.
This approach offers several advantages:
- Scalability
- Lower fees
- Enhanced privacy
- Security.
As a researcher exploring the world of blockchain technology, I’ve come across an intriguing development: ZkSync. Compared to layer 1 solutions, this innovative platform boasts the ability to process transactions at a much faster rate – potentially handling thousands per second. How does it manage such impressive throughput? By batching transactions together, ZkSync efficiently reduces gas fees, making it an economical choice for users.
ZkSync inherits Ethereum’s security as the validity proofs rely on the underlying blockchain’s consensus mechanism.
What sets zkSync apart?
In the world of L2 scaling solutions, ZkSync distinguishes itself with its distinct characteristics. As one of the pioneers in the ZK-rollup category, ZkSync launched its mainnet ahead of many others, granting it an early advantage in terms of user base and development progress. Unlike certain other ZK-rollups, zkSync does without a trusted setup (Application-Specific Trusted Setup or AS-TST), thereby removing a potential focal point for centralization.
In simpler terms, AS-TST refers to the initial configuration procedure for specific cryptographic techniques, such as Zero-Knowledge Proofs. A trusted collective is responsible for generating vital, confidential parameters that bolster the system’s security without compromising the encryption itself.
ZkSync employs a unique method called “Fractal SNARKs” to create proofs of validity, allowing it to efficiently manage a growing volume of transactions. This groundbreaking technology has piqued the curiosity of many developers, making zkSync a leading contender in the quest for scalable Ethereum solutions.
Starting from its mainnet debut in November 2020, zkSync has experienced remarkable expansion. By May 2024, this platform had processed a significant number of transactions, reaching over seven digits, demonstrating its practical applications. The value of cryptocurrencies secured on zkSync surpassed $150 million, distributed among 107 native protocols, reflecting users’ faith in the system. An energetic developer community is taking shape around zkSync, with a multitude of DApps and projects adopting it as their foundation.
What is the difference between zkSync and Starknet?
With ZK-rollup technology, zkSync focuses on supporting versatile smart contracts and seamless integration with Ethereum’s current toolkit. In contrast, StarkNet represents a distinct L2 scaling solution that employs zk-STARK proofs, delivering enhanced scalability but requiring the use of Cairo – a specialized language for writing smart contracts.
Why build on zkSync?
ZkSync opens up intriguing applications that are difficult or costly to achieve on Layer 1. With its affordable fees and swift transaction processing, ZkSync is perfectly suited for blockchain games that involve frequent microtransactions. Decentralized finance (DeFi) platforms can utilize zkSync to provide affordable and quick financial services, thus attracting a larger user base.
Motivated by the crypto community’s avid supporters, also known as degens, the nonfungible token (NFT) marketplace flourishes through swift transactions. ZkSync serves as an economical solution for creating and exchanging NFTs on this platform. The applications of zkSync extend beyond just NFTs, holding significant potential to transform various blockchain uses by tackling scalability issues.
Transferring assets from the Ethereum mainnet (L1) to zkSync (L2) is essential for users to engage with the zkSync ecosystem. Yet, this process involves a bridge, which adds complexity and potential hazards.
Here’s a detailed breakdown of the bridging process and the associated considerations:
How do cros-schain bridges work? A step-by-step guide
Most cross-chain bridges use these basic steps to move assets across chains.
Step 1: The user selects the asset and amount they wish to transfer from Ethereum to zkSync.
Step 2: The bridge locks the user’s chosen tokens in a smart contract on the Ethereum mainnet.
Step 3: An equivalent amount of tokens is minted on zkSync, representing the locked assets on L1.
In simple terms, after completing Step 4, the user obtains their freshly created tokens on zkSync. These tokens are now available for the user to utilize within the zkSync platform.
The process of moving assets from zkSync back to Ethereum works in a similar manner. In this case, the bridge incinerates the zkSync tokens and subsequently releases the corresponding assets on the Ethereum mainnet.
Bridging options for zkSync
Several bridge solutions facilitate asset movement between Ethereum and zkSync.
- Matterport: Developed by Matter Labs, the team behind zkSync, Matterport is a secure bridge designed specifically for zkSync. It leverages a network of validators to ensure the safe transfer of assets and offers a user-friendly interface.
- Generic bridges: Bridges like Synapse can also be used to transfer assets between Ethereum and zkSync. These bridges often support a wider range of tokens but might involve additional fees and potential security risks due to their generic nature.

When selecting a wallet for interacting with the zkSync platform, consider the following factors: The zkSync main site comes equipped with its own wallet, but for larger holdings, hardware wallets such as Ledger offer increased security. Contemplate the ease of use, safety features, compatibility with particular zkSync DApps, and whether you prefer a mobile or web interface when making your decision.
Does Coinbase Wallet support zkSync?
I, as an analyst, can tell you that as of May 2024, zkSync is not natively integrated with the Coinbase Wallet. Consequently, you cannot transfer funds directly from or to your zkSync wallet using this platform. To move your assets between Ethereum, which is supported by Coinbase Wallet, and zkSync, you will need to utilize a bridge for the transaction.
Does Trust Wallet support zkSync?
Sadly, Trust Wallet doesn’t have native compatibility with zkSync. But, you can employ Trust Wallet in conjunction with a bridge to engage with Decentralized Applications (DApps) or shift assets between networks, such as Ethereum, and the zkSync network.
Risks associated with blockchain bridges
As a researcher studying the use of asset transfer technologies, I’ve discovered that bridges provide a convenient solution for moving assets between blockchains. However, it’s essential to be aware of the risks involved. These risks primarily stem from the reliance on smart contracts, which can potentially be vulnerable to hacks or exploits if not adequately secured. Therefore, to mitigate these risks, it is crucial to opt for bridges that have a solid reputation and undergo rigorous security audits regularly.
As a bridge analyst, I would recommend considering the use of decentralized bridges over those that employ centralized custodians for holding assets during transfers. Centralized solutions introduce a single point of failure and potential censorship risks since all control lies with one entity. Decentralized alternatives, on the other hand, utilize distributed validator networks, which mitigate these risks by distributing control among multiple participants.
Users may encounter impermanent loss when interacting with liquidity pools via bridges, as price changes in the bridged asset can have a substantial impact on the value of their positions during the transfer process. Awareness of the inherent risks associated with these pools is crucial.
Bridges, a crucial component of the crypto world, have unfortunately become notorious for being vulnerabilities exploited by hackers. In recent history, incidents such as the Ronin Bridge and Wormhole bridge hacks have resulted in significant financial losses, totalling hundreds of millions of dollars in cryptocurrency assets.
Mitigating risks associated with blockchain bridges
Here are some tips to minimize the risks associated with bridging assets:
- Users should try to choose established bridges with a strong security record and undergo regular audits by reputable security firms.
- It is critical to familiarize oneself with the specific functionalities of the chosen bridge, including fees, supported assets and potential centralization risks.
- If using liquidity pools within a bridge, users must be aware of impermanent loss risks and monitor asset prices to minimize potential losses.
- Users must avoid transferring more assets than they plan to use immediately on any new protocols to minimize exposure to bridge risks.
Through implementing these guidelines, users will be able to make well-informed choices when transferring assets and engage more securely with the zkSync network.
