For developers

Patterns, the official test vectors this checker is tested against, and a widget. A regex checks the shape of an address; only decoding checks its checksum.

A regex is not a validator. It accepts any string of the right shape, including one with a typo. Decode the address and verify its checksum (Base58Check, Bech32/Bech32m, EIP-55, CRC16 …) before trusting it.

Embed the checker

The widget runs the same checks inside the frame; it makes no requests and reports nothing back.

FAQ

What is the regex for a Bitcoin address?

^[13][1-9A-HJ-NP-Za-km-z]{25,33}$ for legacy and ^(bc1|BC1)[…]{8,87}$ for Bech32 — but a regex only checks the shape. Verify the checksum by decoding.

What is the regex for an Ethereum address?

^0x[0-9a-fA-F]{40}$. For mixed-case addresses also verify the EIP-55 checksum.
