Monero address validator
Paste a Monero address. The tool checks its length, network, type (standard, subaddress or integrated) and the built-in checksum, entirely in your browser. A valid checksum catches typos; it cannot tell you who owns the address.
What the check tells you
- Format and checksum. Every Monero address carries a 4-byte checksum. If you mistype a character, the checksum almost always fails.
- Network. Mainnet addresses start with 4 (standard) or 8 (subaddress); integrated addresses are longer (106 characters). Stagenet and testnet addresses use other prefixes and cannot receive real XMR.
- Type. Subaddresses are best for receiving: give each payer a different one. See subaddresses explained.
What it cannot tell you
A valid address can still belong to a scammer. Clipboard-hijacking malware swaps addresses you copy for the attacker's, which also have a valid checksum. Always compare the first and last characters with the address shown by the recipient, and send a small test amount first for large payments. More in Monero scams.
Frequently asked questions
Does this tool send my address anywhere?
No. The check runs in your browser using JavaScript; nothing is uploaded.
Why does my address start with 8?
It is a subaddress. Wallets create these so you can use a different address for each payer.
Can I send XMR to a Bitcoin address?
No. The tool will tell you if what you pasted looks like a Bitcoin or Litecoin address instead.
