Set Up Free Cancellation

Set softCancellations=true in the URL and then send a transaction to self with the same nonce as the one you want to cancel.


This will stop MEV Blocker from broadcasting your previous transaction (it may still get included in rare conditions if it has been broadcasted before). This can be enabled only on /noreverts or /fullprivacy endpoints, soft cancellations won't work on /fast (the default).
