Multi-VM Wallet

A TypeScript implementation of a multi-chain wallet supporting different virtual machines (EVM and SVM).

Features

• BIP32 wallet implementation
• Support for multiple virtual machines:
  • EVM (Ethereum Virtual Machine)
  • SVM (Solana Virtual Machine)
• Transaction handling and signing
• Hierarchical Deterministic (HD) wallet support
• BIP39 mnemonic support

Installation

npm install

Usage

The wallet implements the IChainWallet interface for consistent cross-chain functionality. Each virtual machine implementation (EVM and SVM) follows this interface to ensure consistent behavior across different blockchains.

Basic Usage Example

// Import the wallet implementation
import { WalletBip32 } from './utils/walletBip32';
import { EVMWallet } from './utils/evm';
import { SVMWallet } from './utils/svm';

// Initialize wallets
const evmWallet = new EVMWallet();
const svmWallet = new SVMWallet();

// Work with different chains using the same interface
