real beginner's mistake behind all of this

There's no undo button. No customer service line to call. One wrong click, and the money is just gone.

I nearly sent my own crypto down the wrong network. Nobody stopped me: no warning popped up, no support agent called. So before I moved another coin, I started checking everything first. That's the whole idea behind this site. Here's the exact check, live, right now, not a screenshot of it:

Check one right now.

Paste a destination address and pick what you're sending. This is the real tool, running in this page, checking the format and checksum instantly. Nothing you type here ever leaves your browser.

This checks format and checksum only. The full tool also checks live on-chain activity and covers 10 assets, including LINK, SEI, and DUSK. Open the full checker →

Education, not financial advice. I'm not a financial advisor: always do your own research.
Guides

Plain-English, one mistake at a time

Every guide is a real interactive checklist. Tick boxes as you go, built from mistakes that actually happen.

Built by the person from that near miss.

Most crypto guides are written by developers, for traders. I'm neither. I'm an ordinary person in Essex who moved my own crypto off exchanges and slowly worked out how to stay safe, all without learning to code.

These guides and this checker are the instructions I wish someone had given me: short, plain English, and honest about the mistakes that actually lose people money.

No account. No catch. Just checks that catch the mistake before it's permanent.
