Bitcoin Mainnet and Test Networks: Keep Addresses Separate

This service generates Bitcoin mainnet P2PKH addresses. A result is not a testnet address merely because you intend to use it for testing.

Short answer: This service generates Bitcoin mainnet P2PKH addresses. A result is not a testnet address merely because you intend to use it for testing.

Testing an interface is not selecting a test network

The current BTCVanity output is Bitcoin mainnet legacy P2PKH. A small pattern used for a demonstration still produces a mainnet result. The interface does not select testnet, signet or regtest for you.

Network selection also matters in wallet software and explorers. Seeing no history in an explorer can mean that you selected the wrong network, or simply that no transaction has used that address.

Keep network encoding and private keys separate

A private scalar is not a complete receiving instruction. Address and key-export formats include conventions that software uses to interpret the result. Do not manually change a prefix to make a result appear suitable for a different network.

A superficially similar address on another blockchain is not evidence of compatibility. A payment instruction should identify both the complete destination and the intended network.

Record the context with your backup

When recording an exported key, include a separate non-secret note identifying Bitcoin mainnet, the expected P2PKH address and the wallet workflow you intend to use. That note does not replace the secret itself.

Consult the WIF import guide for compatibility checks and the output-format guide for what this generator returns. Do not send funds merely to find out whether a wallet accepted the right network.
