About this calculator

Bech32 is the checksummed text encoding defined in BIP173 for representing Bitcoin's SegWit (native witness) addresses. It combines a human-readable prefix — like “bc” for Bitcoin mainnet — with the witness program data, encoded using a 32-character alphabet chosen to minimize the chance of transcription errors and support strong error detection.

Bech32 addresses are the ones that start with “bc1”, and their checksum lets a wallet reliably catch mistyped or corrupted addresses before funds are sent to the wrong place — a major usability improvement over the older Base58Check format. Wallet developers, exchange engineers, and blockchain tooling builders use encoders like this to generate and validate bech32 addresses when implementing SegWit support.
