BrowserProvider

Overview

The BrowserProvider is a new class in the mitumJS (v2.2.0+) designed to standardize communication between dApps and browser-based Mitum wallets (such as Fact Wallet).

This class follows the EIP-1193 standard, acting as a high-level wrapper for the provider object injected by the wallet (e.g., window.imfact). It provides dApp developers with a convenient and familiar interface, similar to ethers.js's BrowserProvider.

BrowserProvider class is used for dApp-to-wallet communication: requesting accounts, signing transactions, and handling wallet events.

Environment: Browser (ESM) Only

The BrowserProvider is intended exclusively for browser environments and should be used with the SDK's ES Module (ESM) bundle (bundle.esm.mjs). This bundle includes the necessary browser polyfills (like Buffer) automatically.

This class should not be used in Node.js (CJS) environments. For Node.js, use the main Mitum class for all operations.
