Bitcoin tools to check things yourself
Free, no signup, no private keys requested. Each tool only processes what you paste in — nothing more.
Privacy audit -- Analyze your own wallet for links to known exchanges and patterns that could compromise your privacy.
Address analyzer -- Paste an address and re-run the automated analysis of its relationships: funding, external clustering, and possible links.
BIP353 checker -- Check whether a BIP353 payment identifier is correctly set up, validating the full DNSSEC chain locally.
Wallet movement report for advisors -- A statement of a Bitcoin wallet's movements (one or several xpubs) that separates what is certified, what is hypothesis, and what is a gap. It computes no taxes.
