Bitcoin Address Generator — FAQ
What Bitcoin address formats are supported?
We support all four Bitcoin address formats: Legacy (P2PKH, starting with 1), SegWit (P2SH, starting with 3), Native SegWit (bech32, bc1), and Taproot (bech32m, bc1p).
Can I generate testnet Bitcoin addresses?
Yes. You can generate both mainnet and testnet Bitcoin addresses. Testnet addresses work with Bitcoin testnet faucets for development.
Are generated Bitcoin keys secure?
Keys are generated using the Web Crypto API's cryptographically secure random number generator. However, they are intended for testing — never use generated wallets for real Bitcoin.
