Description

Closes #103

This PR introduces support for the TON (The Open Network) ecosystem by implementing two of its primary wallet paradigms: v4r2 and the next-generation w5 (v5r1). This allows users to derive TON specific addresses and manage keypairs directly through hdwallet.

Changes Introduced

1. TON v4r2 Support

• Implemented the standard v4r2 (Version 4 Revision 2) wallet address derivation.
• For reference, see the TON Wallet Comparison Documentation.

2. TON w5 (v5r1) Support

• Added support for the new W5 (Version 5 Revision 1) wallet standard.
• For technical specifications, see the Official Wallet V5 Documentation and the upstream TON Wallet Contract V5 Repository.

Usage Example

from hdwallet import HDWallet
from hdwallet.cryptocurrencies import Ton
from hdwallet.mnemonics import BIP39Mnemonic

# Initialize TON HDWallet
hdwallet = HDWallet(cryptocurrency=Ton)
hdwallet.from_mnemonic(mnemonic=BIP39Mnemonic(mnemonic="your mnemonic"))

# Retrieve address for specific wallet versions
print("Address (v4r2):", hdwallet.address(wallet_version="v4r2"))
print("Address (w5):", hdwallet.address(wallet_version="v5r1"))
# it is default for w5 print("Address (w5):", hdwallet.address())
print("Path:", hdwallet.path())
print("Public key:", hdwallet.public_key())
