Rush towards hyperscalability on zkSync using Blast APIs

zkSync, developed by Matter Labs, is a secure and user-friendly Layer 2 protocol designed for scalable and affordable transactions on Ethereum, utilizing zkRollup technology, prioritizing security, user experience, and developer experience.

Benefits of zkSync

About zkSync

zkSync is a Layer 2 (L2) protocol, designed to scale and enhance privacy on the Ethereum ecosystem. Additionally, it offers low-cost ETH and ERC20 token transfers, as well as features such as atomic swaps, limit orders, and integrated support for L2 non-fungible tokens (NFTs).

The network operates on a zk-Rollup architecture. zk-Rollups are off-chain scaling protocols that combine several transactions into batches to execute off the main chain. Each Rollup block produces a state transition zero-knowledge proof (SNARK) that is confirmed by the main chain contract. This proof confirms the legitimacy of every transaction in the Rollup block. Moreover, updates to the public data for each block are disseminated across the mainchain in a cost-efficient manner using calldata.

Blast Features for zkSync Developers

Core API

Blast custom APIs offer optimized throughput and reduced latency for transactions on Metis and enable access to real-time data, transaction history and network status.

Included with all plans

Debug API

The Debug API gives OP developers access to several non-standard RPC methods, which will allow them to inspect, debug and set certain debugging flags during runtime. Debug API is enabled starting with the Developer plan.

Included with Developer, Startup, Enterprise & Pay As You Go plans

Archive Nodes

These nodes retain all historical transaction information on the Gnosis blockchain from the genesis block to the present, enabling users to query and retrieve any past information. The Archive Nodes feature is enabled starting with the Developer plan.

Frequently Asked Questions

What are zk-rollups?

zk-Rollups are a blockchain scaling solution that groups multiple transactions into one, reducing the load on the main network. They utilize zero-knowledge proofs, a cryptographic method allowing for transaction validation without revealing their details. This ensures transaction privacy and security.

What are some use cases for zkSync?

Given its high throughput and low costs, zkSync's enhanced scalability can help with deploying a wide range of dApps such as DeFi Projects, NFTs, Gaming Projects and dApps using Cross-chain Connected Contracts.

How do I start building on zkSync with Blast?

Simply click on Launch App, connect your wallet and get access to dedicated endpoints that you can organize into projects depending on your development needs.
