Decentralized Wallet

This is a command-line decentralized wallet that supports multiple EVM-compatible blockchains, including Ethereum, Arbitrum, Optimism, and Base, as well as Bitcoin and EOS.

Features

• Multi-Chain Support: Supports Ethereum, Arbitrum, Optimism, Base, Bitcoin, and EOS.
• Address Generation: Generates new addresses for supported blockchains.
• ** फंड Transfer:** Allows transferring funds on EVM-compatible chains.
• Transaction History: Retrieves transaction history for specified addresses on EVM-compatible chains.

Usage

The wallet is controlled through command-line arguments.

Environment Setup

Before using the wallet, you need to set the following environment variables. You can copy the .env.template file, rename it to .env, and replace the placeholders with your actual values:

• ETHEREUM_RPC_URL: RPC URL for the Ethereum network.
• ARBITRUM_RPC_URL: RPC URL for the Arbitrum network.
• OPTIMISM_RPC_URL: RPC URL for the Optimism network.
• BASE_RPC_URL: RPC URL for the Base network.
• WALLET_SEED: The seed phrase for generating wallet keys. Important: Keep this secure and do not share it.
• ETHEREUM_CHAIN_NAME: The name used to identify the Ethereum chain (e.g., "ethereum").
• ARBITRUM_CHAIN_NAME: The name used to identify the Arbitrum chain (e.g., "arbitrum").
• OPTIMISM_CHAIN_NAME: The name used to identify the Optimism chain (e.g., "optimism").
• BASE_CHAIN_NAME: The name used to identify the Base chain (e.g., "base").

Commands

• address <chain>: Retrieves the address for the specified blockchain.

  • Example: tokit address ethereum
  • Supported chains: ethereum, arbitrum, optimism, base, bitcoin, eos

• transfer <chain> <to_address> <amount>: Initiates a transfer on the specified blockchain.

  • Example: tokit transfer ethereum 0x1234abcd 1.0
  • Parameters:
    • <chain>: The blockchain to perform the transfer on (ethereum, arbitrum, optimism, base).
    • <to_address>: The recipient's address.
    • <amount>: The transfer amount.

• history <chain> <address>: Retrieves the transaction history for the specified blockchain and address.

  • Example: tokit history ethereum 0x1234abcd
  • Parameters:
    • <chain>: The blockchain to query the transaction history from (ethereum, arbitrum, optimism, base).
    • <address>: The address to query the transaction history for.

Supported Chains

• Ethereum
• Arbitrum
• Optimism
• Base
• Bitcoin (address generation only)
• EOS (address generation only)

Important Notes

• This is a basic implementation and does not include secure key management or transaction signing functionalities.
• RPC URLs are read from environment variables. Ensure these are correctly configured before running the wallet.
• The wallet generates a new key pair for each address request. In a real-world scenario, key management would be handled more securely.
• The wallet uses a mnemonic phrase to generate a master private key and then uses Hierarchical Deterministic (HD) paths to derive child private keys for each chain. This implementation uses a placeholder for key derivation and should be replaced with secure key generation and management practices for production use.
• The transfer and history commands are only supported for EVM-compatible chains (Ethereum, Arbitrum, Optimism, Base).
