### Cancellation costs
For transactions sent using Flashbots Protect without fast mode, this transaction is only used for authentication to ensure that you control the account that sent the transaction you want to cancel. This method allows for easy cancellation of transactions from retail wallets like MetaMask. The cancellation transaction will not be sent to the relay nor the miners.

Note. This probably means there is an admin rpc method that is 'evicting' the transaction from the RPC mempool
