## Detection

Regular expression (Python `re`):

```
^(?:bc1p[02-9ac-hj-np-z]{58}|BC1P[02-9AC-HJ-NP-Z]{58})$
```

Check digit algorithm: `bech32m`

## Examples

- `bc1p0xlxvlhemja6c4dqv22uapctqupfhlxm9h8z3k2e72q4k9hcz7vqzk5jj0` — BIP 350 test vector
- `bc1p0xlxvlhemja6c4dqv22uapctqupfhlxm9h8z3k2e72q4k9hcz7vqzk5jj2` (invalid example) — last character changed, the checksum fails
- `bc1qrp33g0q5c5txsp9arysrx4k6zdkfs4nce4xj0gdcccefvpysxf3qccfmv3` (invalid example) — witness version 0 address (p2wshaddr)
