The keys stay with you.
SWOP isn't a wallet we hold for you — it's the tool to make your own. Spin up one wallet or a hundred, operate on Ethereum, and walk away. Keys are generated and kept on your machine; the moment you close the app, every trace is wiped. Enter, operate, exit.

Not a wallet we hold. Yours.
Crypto exists so that you — not a company — hold the keys. A custodial wallet is like a bank account: on paper it's yours, in practice someone else controls it. SWOP flips that. It generates and signs on your own machine and keeps nothing — we don't have your keys, your funds, or even a record that you opened it. The website stays watch-only; the operating stays with you.
Export a paper wallet

Generate a self-contained backup — public address, private key, recovery phrase and QR — then print it and keep it offline. Zero-persistence export: nothing is saved once you close the session.
Unplug the world.
Boot your vault.
SWOP can turn any USB stick into Whales OS — a self-contained operating system. Power your computer off, boot from the stick, and generate wallets or sign completely outside your everyday system: no Windows, no drivers, no malware, no trace. The most paranoid way to operate — in the best sense of the word.
