# Cardano address (Shelley) (`cardano_address`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Shelley-era address of Cardano as specified by CIP-19, encoded with Bech32 without a length limit. Payment addresses have the prefix addr (base, pointer, enterprise and script addresses) and reward addresses the prefix stake; the first data character encodes the address type. Testnet addresses (addr_test, stake_test) and Byron-era Base58 addresses are not matched.

- Parent datatype: `crypto_address`
- Personal data (PII): no
- Categories: Cryptocurrency (cryptocurrency)
- Countries: global
- Languages: Common to most languages (common)
- Classification: identifier

## Detection

Regular expression (Python `re`):

```
^(?:addr1|stake1)[02-9ac-hj-np-z]{53,}$
```

Check digit algorithm: `bech32`

## Examples

- `addr1qx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzer3n0d3vllmyqwsx5wktcd8cc3sq835lu7drv2xwl2wywfgse35a3x` — CIP-19 test vector, base address (type 0)
- `addr1vx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzers66hrl8` — CIP-19 test vector, enterprise address (type 6)
- `stake1uyehkck0lajq8gr28t9uxnuvgcqrc6070x3k9r8048z8y5gh6ffgw` — CIP-19 test vector, reward address (type 14)
- `addr1vx2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzers66hrl9` (invalid example) — last character changed, the checksum fails
- `addr_test1vz2fxv2umyhttkxyxp8x0dlpdt3k6cwng5pxj3jhsydzerspjrlsz` (invalid example) — testnet address
