Starts with 3 | 25-34 chars | Base58

Native SegWit (Bech32)

Native Segregated Witness address. Starts with 'bc1q'. Lower fees and better error detection than legacy formats.

❓ Frequently Asked Questions

What are the different Bitcoin address types?+

Legacy (1...) uses P2PKH, SegWit (3...) uses P2SH, Native SegWit (bc1q...) uses Bech32, and Taproot (bc1p...) uses Bech32m. Newer formats offer lower fees and better privacy.

Can a valid Bitcoin address still be a scam?+

Yes. A valid format doesn't mean the address belongs to who they claim. Always verify addresses through multiple channels and double-check every character before sending funds.

Why do Bitcoin addresses have checksums?+

Checksums prevent sending Bitcoin to mistyped addresses. If you change a single character, the checksum won't match and wallets will reject the address, protecting your funds.
