Introduction - ZKsync Docs

A Provider interacts with the blockchain network, allowing applications to send transactions, query data, and listen to events. Providers bridge the application and blockchain, ensuring smooth communication.

The zksync-ethers library supports providers from the ethers.js library and adds extra functionality.

Two providers are available:

Provider: Functions like ethers.providers.JsonRpcProvider with added ZKsync-specific methods.
Web3Provider: Extends the ZKsync Era Provider class for better compatibility with Web3 wallets.

Use the Web3Provider for browser integrations.

`Provider`

The Provider class in the zksync-ethers library extends the ethers.providers.JsonRpcProvider with additional ZKsync-specific methods. This lets users access advanced ZKsync features using the familiar ethers.js interface.

`Web3Provider`

The Web3Provider class extends the ZKsync Era Provider class for better compatibility with Web3 wallets, making it ideal for browser-based integrations. This provider ensures seamless interaction with wallet extensions like MetaMask, allowing users to manage accounts and sign transactions directly from the browser.
