Monero payments cannot be undone, so a wrong address is an expensive mistake. These free Monero tools run in your browser and catch the slip before it costs you. The address validator and restore height calculator send nothing anywhere; the fee calculator loads live block data, but what you type stays in the page. There is nothing to sign up for.

Ready now
Paste any address and see in a blink whether it looks like a real Monero address, which network it is for, and what type it is.
Pick a date and get the block height to restore from, or turn a height back into a date. It starts 7 days early so the scan cannot miss a payment.
See what a payment costs right now, at every priority. The numbers are measured from real transactions in the latest blocks, not guessed.
Turn an address into a payment QR code and a standard monero: link, with an amount and a note if you like. Made in your browser, nothing uploaded.
What would your computer earn mining Monero? Enter your hashrate, power and electricity price. Network difficulty is live, the result is an honest estimate.
Why these tools
There is no bank to call and no chargeback. The only safe moment to catch a mistake is before the money moves. Each tool here covers one place people trip.
The address check and the restore height lookup happen in the page, and nothing is sent anywhere. The fee calculator fetches recent block data from our server; what you type is never sent.
You get the reason in plain words, so you learn what to look for next time.
The validator checks the checksum, so typos are caught, and says plainly what it cannot know: whether the address belongs to the person you mean to pay.
Need a wallet to go with the address? It takes about two minutes.
