AddressGuard: Bitcoin Checker

Clipboard malware swaps Bitcoin addresses after you copy them. One wrong character and the coins are gone for good. AddressGuard compares the address you trust with the one you're about to send to, character by character, and shows every difference in red. Bitcoin-only, works offline, supports Lightning invoices and LNURL. No account, no wallet connection, no keys. HOW IT WORKS 1. Paste, scan or photograph the address you trust: from the person, the exchange or the invoice. 2. Paste the address your wallet is about to send to. 3. Get a plain answer: "Addresses match" or "Do not send — characters are different", with every changed position highlighted. WHAT IT CHECKS • On-chain Bitcoin addresses: legacy, P2SH, SegWit (bc1q) and Taproot (bc1p), with checksum validation • Lightning invoices, Lightning Addresses and LNURLs, validated locally and never resolved over the network • Character-by-character comparison with adjustable text size and VoiceOver support • Loud mismatch alarm with haptics and sound, so a swapped address can't slip past you ADDRESSGUARD PRO Your first three comparisons are free. Pro adds unlimited comparisons, saved trusted addresses, full local history and export. Choose a one-time Lifetime unlock or a Pro Annual subscription. Pro Annual renews automatically each year unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation. Manage or cancel any time in your App Store account settings. PRIVACY BY DESIGN • No account • No analytics, advertising or crash-reporting SDKs • No network calls: comparisons, saved addresses and history stay on this device unless you export them • Never connects to a wallet, never asks for keys or seed phrases, never signs, sends or broadcasts anything Important: AddressGuard helps you spot differences. It cannot guarantee fund safety, prove who controls an address, prevent every loss or recover a wrong send. Always review your transaction.
