It creates addresses, private keys, and mnemonics for multiple blockchains.</p> <h2> ⚠️ Important Notice </h2> <p>Before you get too excited, let me be clear:</p> <p><strong>VaultForgeWalletBot is currently a wallet generator, not a full operational wallet.</strong></p> <p><strong>What it does:</strong></p> <ul> <li>Generates: address, private key, and mnemonic.</li> <li>Supports multiple blockchains (BTC, ETH, SOL, and more).</li> <li>Works entirely inside Telegram.</li> </ul> <p><strong>What it does NOT do yet:</strong></p> <ul> <li>Connect to blockchain networks (BTC, ETH, etc.).</li> <li>Monitor addresses.</li> <li>Know when funds are sent or received.</li> </ul> <p><strong>This means</strong>: You can generate wallets, but you cannot send, receive, or track funds through this bot yet. Full wallet functionality is coming soon.</p> <h2> Why I Built It </h2> <p>I wanted a simple way to generate wallets without relying on third-party websites. Telegram felt like the perfect place because it's already on every device I use.</p> <h2> Features </h2> <ul> <li> <strong>Wallet Generation</strong>: Creates addresses, private keys, and mnemonics.</li> <li> <strong>Multi-Chain Support</strong>: Generates wallets for Bitcoin, Ethereum, Solana, and more.</li> <li> <strong>No Separate App</strong>: Everything happens inside Telegram.</li> <li> <strong>Simple Commands</strong>: Easy to use, even for beginners.</li> </ul> <h2> How to Use </h2> <ol> <li>Open Telegram and search for <code>@VaultForgeWalletBot707_bot</code>.</li> <li>Start the bot and follow the instructions.</li> <li>Generate your wallet.</li> </ol> <h2> Roadmap </h2> <ul> <li>[x] Wallet generation (address, private key, mnemonic)</li> <li>[ ] Blockchain integration (BTC, ETH, SOL)</li> <li>[ ] Send/receive functionality</li> <li>[ ] Transaction tracking</li> <li>[ ] Multi-wallet support</li> </ul> <h2> Links </h2> <ul> <li> <strong>GitHub</strong>: <a href="https://github.com/Bimoxu/vaultforge-wallet-bot" rel="noopener noreferrer">vaultforge-wallet-bot</a> </li> <li> <strong>Telegram Bot</strong>: <a href="https://t.me/VaultForgeWalletBot707_bot" rel="noopener noreferrer">@VaultForgeWalletBot707_bot</a> </li> </ul> <h2> Feedback Welcome </h2> <p>I'd love to hear your thoughts and suggestions.
