Create me a full HTML code.for a unconfirmed btc transaction wallet changer with all fees prepaid in full ,spendable and confirms in 6

Creating a full HTML code for a Bitcoin wallet changer for unconfirmed transactions requires a deep understanding of blockchain technology, the Bitcoin protocol, and the associated security considerations. Additionally, handling transactions and wallets involves dealing with sensitive data.

For educational purposes, I can provide a simplified version of a front-end interface that could hypothetically manage Bitcoin transactions. However, this will not handle actual transactions since it lacks backend processing, encryption, and security measures crucial for handling cryptocurrency.

Here's a basic HTML template that you might use as a starting point for a user interface to track and potentially manage BTC transactions. Note that real transaction handling needs server-side programming, secure wallet management, and thorough testing.

### Important Considerations
- **Security**: This code does not address security concerns like user authentication or secure data transmission. When dealing with cryptocurrencies, security is paramount.
- **Backend Processing**: A functional application would need backend logic to interact with a blockchain node or a cryptocurrency payment processor.
- **Real Transactions**: Always test with a non-productive environment (testnet) and ensure compliance with legal regulations regarding cryptocurrency transactions in your jurisdiction.
- **Validation**: Be sure to validate user input thoroughly to prevent errors and security vulnerabilities.
