What Is “Transaction Spamming” and How Does It Affect the Mempool and Fees?

Transaction spamming is the act of broadcasting a large volume of low-value or unnecessary transactions to the network. This artificially inflates the size of the mempool, making it appear highly congested.

The goal is often to clog the network, slow down legitimate transactions, and force users to bid higher fees to get included, thus temporarily driving up the fee market and creating a negative user experience.
