    Ankr Launching Developer RPC Connection To zkSync

    Ankr will soon release a zkSync RPC connection, allowing Web3 apps and developers to easily build on the “end-game” for Ethereum scaling.

    Ankr is very excited to announce we are beginning our latest RPC collaboration with zkSync! This is excellent news for developers seeking to build on the Ethereum scaling solution gaining buzz for its novel enhancements to ZK technology.

    Developers will soon be able to access the zkSync Testnet and Mainnet with Ank’s Public, Premium, and Enterprise RPC endpoints. They can then make request calls using standard EVM methods, and receive information returns that are identical to the results they would get by running a zkSync node themselves.

    “We are very excited to see zkSync get to work scaling the Ethereum ecosystem. With Ankr providing a connection to the Layer-2 chain for every builder and Web3 app, this could be one of the most powerful scaling solutions we’ve seen to date.”

    zkSync: An Unlimited Ethereum Scaling Scaling Solution

    zkSync leverages ZK rollup tech with cryptographic validity proofs to provide immense scalability and always-affordable transactions on Ethereum. zkSync uses a novel system to account for most computing and data storage needs off-chain while all transactions are proven on the Ethereum mainnet for maximum security.

    zkSync has several highlights that will allow Web3 apps to push the boundaries of scalability:

    • Mainnet-like security with zero reliance on 3rd parties
    • Permissionless EVM-compatible smart contracts
    • Standard Web3 API
    • Preserving key EVM features, such as smart contract composability
    • Introducing new features, such as account abstraction

    Soon, when zkSync executes its full launch, some of the largest ecosystem apps like Maker, 1inch, Uniswap, Sushi, and Binance Wallet will be utilizing it to accelerate fullscale Web3 use and adoption.

    zkSync is an extremely promising scaling solution with the potential to break new ground in scaling Web3. However, it needs more developer resources to let builders connect to the zkSync chain. To cater to the thousands of new developers looking to work with zkSync, Ankr is providing a way they can easily contribute to this expanding network.

    What Are Ankr’s New zkSync RPC API Connections?

    • Ankr’s zkSync RPCs (Remote Procedure Calls) will connect your wallet, command-line interface, or dApp with the zkSync L2 blockchain. They act as a messenger or blockchain router that relays on-chain information between zkSync nodes, dApps, and ultimately end-users so they can execute necessary tasks like transactions, populate wallet balances, fetch ownership information, and more.
    • zkSync RPC endpoints are a gateway for developers to interface directly with the zkSync chain — a portal to communicate easily, remotely, and with no need to go through the DevOps of establishing their own zkSync nodes.
    • Ankr is providing a geo-distributed zkSync RPC comprised of blockchain nodes running worldwide for incredibly low-latency and reliable connections.

    How Will the zkSync RPCs Help Developers?

    Building with zkSync is an excellent choice to create scalable Ethereum ecosystem dApps but requires access to the information on zkSync nodes to do so. Therefore, Ankr’s RPC solves the following developer troubles:

    • Eliminates complex node ops - Ankr’s zkSync RPCs will completely remove the need for many developers to set up their own zkSync nodes, removing hours of time spent building, calibrating, and fixing node issues.
    • Grants access to advanced tools -  Ankr’s Premium RPC Plan instantly grants access to the best tools to build applications quickly, including:
    • At least 1,500 zkSync req/sec
    • Dedicated zkSync endpoints
    • Prioritized requests
    • WebSockets (WS) capabilities
    • Powers apps and open-source software that need access to zkSync - Connect with a cluster of high-performance nodes that holds the information you need to build and operate dApps with zkSync chain capabilities.
    • Supports the zkSync networkAnkr will strengthen the zkSync network globally by offering easier development and a broader, decentralized node infrastructure.

    How to Make Your First Call to zkSync

    You will soon be able to get started by heading to

    Ankr’s RPC Service

    to make your first call! You can then use the zkSync endpoint to call the chain using the standard EVM JSON RPC methods.
