Protect my wallet

Crypto finally has backsies.

Every transfer waits a few minutes before it lands. Changed your mind, clicked a bad link, pasted the wrong address? Take it back.

Press Take it back within 10 seconds to cancel the demo transfer.

On every other rail, mistakes have an undo. On-chain, one bad signature is forever.

Send it. Regret it. Take it back.

  1. You send.

    Your transfer waits in the Backsies vault.

  2. You get pinged.

    “5 ETH is leaving your wallet. Was that you?”

  3. You decide.

    Let it go, or take it back to your safe address.

Even if someone steals your keys, they can’t steal your backsies.

Cancelled funds only ever go to the safe address you set, and changing it takes 48 hours.

The riskier it looks, the longer it waits.

Backsies sets the undo window from the transfer itself: who is receiving it and how much is leaving. Try it.

Never longer than 72 h

The whitepaper fixes the endpoints: 0 min to an allowlisted address, 5 min for a small amount to a new address, 24 h for a large amount to a suspicious contract, 72 h at most. The curve in between is illustrative.

What Backsies can’t do (yet).

The Undo RPC stops bad transactions you sign yourself. It can’t stop someone who already has your seed phrase: full protection against key theft comes with Vault Mode, a smart account planned for Phase 2. All the known limits
