"How does Mempool Accelerator™ work?

Mempool sends your acceleration request to our mining pool partners. Partners who choose to accept your acceleration request prioritize your transaction based on your new accelerated fee rate.

For example, if you use Mempool Accelerator™ to accelerate a 1 sat/vB transaction to a 20 sat/vB target fee rate, mining pool partners will treat the transaction as though it has a 20 sat/vB fee rate."
