Ctrl+ArcZ: Undo a Payment

Sent it to the wrong address? Now you can take it back. Ctrl+ArcZ sends USDC the way a bank transfer never could: It stays yours until the recipient claims it. A protected transfer goes out with a one-time code. The money sits in escrow, not in the recipient's wallet, until they enter that code. Sent to the wrong address, or changed your mind? Undo it and the funds come straight back. If nobody claims it before the window you set closes, you reclaim it. BEFORE YOU SEND Every recipient is screened first. Addresses that mimic one you have used before, addresses that have only ever received, addresses linked to known drainers: you are told before the money moves, not after. UNDO One key at the centre of the app opens everything still inside its window, with the time left on each. One tap takes it back. PRIVATE PAY Pay a merchant from a fresh, single-use address that carries none of your identity on chain. Set up a recurring payment with a hard cap per charge and an end date, and cancel it whenever you like. BRIDGE Move USDC between Arc, Ethereum, Base, Arbitrum, Optimism, Polygon and more, through Circle's own CCTP and Gateway. YOUR KEYS Non-custodial. Your private key is generated on your device, encrypted by the Android keystore, and never leaves it. There is no account and no sign-up. Screens that show a key or a claim code refuse to be screenshotted, and nothing sensitive goes into a cloud backup. TEST NETWORK ONLY This release runs on Arc Testnet. The USDC in it is test currency with no monetary value and cannot be exchanged for anything. Nothing here moves real money.
