Is It Safe to Enter Your Seed Phrase Into a Recovery Tool?
Short answer: only if it runs entirely in your browser and sends nothing to a server. Here's how to tell a safe seed phrase recovery tool from a scam.
It's a fair question — and asking it is a sign you're being careful. Typing a seed phrase into the wrong tool can drain a wallet in seconds. Typing it into the right one, the right way, is safe. Here's how to tell them apart.
The one rule that matters
Your seed phrase must never leave your device. A recovery tool is safe only if every calculation happens locally — in your browser — with nothing sent to a server. If a "recovery" site uploads your words to "process them," treat it as theft in progress.
That's the entire design principle behind this tool: the recovery engine is compiled to WebAssembly and runs inside your browser tab. Your words are never transmitted, logged, or stored. You can read more on the homepage — and verify the claim yourself (below).
How to verify "client-side" for yourself
You don't have to take anyone's word for it:
- Read the code. Prefer open-source tools. If you can't see the source, don't trust it with your phrase.
- Pull the network cable / turn off Wi-Fi. Load the page first, then go offline. If the tool still works completely, it isn't talking to a server.
- Watch the network tab. Browser dev tools show every request a page makes. Type a dummy phrase and confirm nothing is sent.
A genuinely client-side tool passes all three.
The safest possible workflow
For high-value wallets, go a step further:
- Download or load the tool, then disconnect from the internet before entering anything.
- Run the recovery offline.
- Treat the recovered phrase as potentially exposed and move funds to a brand-new wallet generated on a clean, offline device.
This way, even a compromised computer can't benefit from what you typed.
Red flags of a recovery scam
Walk away immediately if a tool or person:
- Asks you to send your seed phrase, private keys, or keystore file anywhere.
- Charges an up-front fee to "unlock," "validate," or "release" your funds.
- DMs you "support" after you posted about a lost wallet (this is a swarm of scammers, not help).
- Promises to recover a wallet from nothing — impossible if you have no backup.
- Pressures you to act fast. Urgency is a manipulation tactic.
Remember: no legitimate wallet, exchange, or service will ever ask for your recovery phrase. Support staff don't need it and can't use it for you.
Why a real recovery tool can be safe
Recovery is just maths on data you already hold — checking a checksum, trying candidate words, deriving addresses. None of that requires a server. A tool that keeps the maths on your machine gives you the help without the exposure. That's the bar to hold every tool to, including ours.
