Withdrawal stuck at "verify your wallet"? Prove it in minutes, keys stay yours.
KeyProof shows you exactly how your exchange wants you to prove you own your wallet: message signing, Satoshi test, screenshot or declaration. It then checks your signature locally and gives you a proof record to reuse next time.
Free today: every exchange guide, wallet how-tos, the verifier and proof downloads. A paid Pro plan (saved proofs and alerts) is planned but not for sale yet.

No seed phrases, no private keys, no wallet connection needed to read a guide. We never hold funds.

FAQ
Will KeyProof ever ask for my seed phrase or private key?
Never. KeyProof only works with public data: your address, the exchange's message and the signature your own wallet produces. Anyone asking for your recovery words is a scammer.
Does the verifier send my data anywhere?
No. Signature verification and proof-record generation run entirely in your browser. The site's Content-Security-Policy blocks connections to any other server, so the page could not send your data elsewhere even if it tried.
Which exchanges do you cover?
Coinbase, Kraken, Binance, Bitstamp, Bitvavo, Bitpanda and Crypto.com, each with citations to the exchange's own help center. All guides are free to read.
Is this legal advice?
No. KeyProof is an information and software tool, not legal, tax or financial advice. Always follow your exchange's own instructions.
