Have you ever sent crypto to the wrong blockchain by mistake? This gap in wallet security costs millions every year

Cross-chain address mistakes are one of the most silent and permanent fund losses in crypto. You paste a Solana address while on Ethereum, or a Bitcoin address on BNB Chain. The address isn't flagged as malicious — because it isn't. It just belongs to a different network. Funds gone forever, no recourse.

What's surprising is that no major wallet security tool catches this. Blacklist scanners, phishing detectors, contract analyzers — none of them check address format compatibility across chains. They only check if an address is malicious, not if it's on the wrong chain.

I built a MetaMask Snap that solves exactly this — it checks address formats in real time before you confirm any transaction.

I actually thought of that after seeing a guys post in here a few months ago saying that he lost his funds sending to the wrong chain and was wondering if there was a way to get them back.

You can find it on the latest snaps in the official Metamask Snaps Directory but i guess i am not allowed to name it directly in the main post.

I also started discussing with different wallet teams for a native integration so we can solve that issue once and for all.

Would you want to have that on your wallets natively to make sure you don't send your funds to the wrong chain?
