Now see that almost every transaction is a send to self transaction. Now click into one of those transactions and you see that they are sending themselves 0 matic, and just paying gas, like this Polygon Transaction Hash (Txhash) Details | PolygonScan
These are not interacting with any contracts or doing anything like that. This is a DoS attack on the chain. It has been ongoing for a while now.
also worried about this. How can we solve this? I also commented on proposal to implement EIP-1559, which, to my knowledge would lower the gas fees even more. EIP-1559 on Polygon
It would be nice to have some official response from devs. In my understanding there is nothing that can be done about this. People have to pay higher gas price than the spammer and this will eventually drive transaction cost up.
