- **Private Key (Optional)** (text): Enter private key in hex or WIF format (leave empty to generate new)

## When to use

- When you need to derive a public address from an existing private key for wallet recovery or verification.
- When you are developing or testing blockchain applications on the Bitcoin Testnet.
- When you need to generate a new, secure key pair and address for a fresh wallet setup.

## How it works

- Select your preferred address type (Legacy, Multisig, or SegWit) and the target network.
- Input your existing private key in hex or WIF format, or leave the field blank to generate a new random key pair.
- Click the generate button to compute the corresponding public address instantly.
- Copy the resulting address and private key securely for your records.

## Use cases

- Verifying the public address associated with a specific private key.
- Generating new addresses for cold storage setups.
- Testing transaction flows on the Bitcoin Testnet.
