Create a Double-spending Transaction

Service Rules

Unsigned double-spending transaction will generated at server side and returned back
Private Key will be never sent out from your computer, new transaction will be signed in your browser! (Open Source code)
You need to specify Private Key of any your Address from the previous still unconfirmed transaction, only this Input will be double-spent
If more than one Input with the same Address in the unconfirmed transaction - Input with the highest amount will be selected and double-spent
All other Inputs (if any) will become available again in your wallet after new double-spending transaction confirmed by network
You may doublespend each Input (if multiple Inputs) as new transaction or doublespend just any one Input Address
New transaction will be broadcasted to the BTC network via our own specially configured nodes (no txn-mempool-conflict error)
Double-spending time can not be estimated but usually this is less than 48 hours, even a few minutes for RBF-enabled transactions
You will be able to verify New Transaction and check all Outputs and Amounts before Broadcast at Verify Tab
Bitcoin (BTC) is only supported for double-spending, no Bitcoin Cash, Gold or other bitcoin forks
This is not free-of-charge service. No refund under any circumstances.
Service fee BTC address will be automatically added to newly generated transaction
Service fee is 10% of Input Amount, but no less than 0.005 BTC (min) and no more than 0.05 BTC (max)
