How to get a transaction on electrum to stop brodcasting ?
Made a transaction over 24 hours ago, now I want to "cancel" it and stop broadcasting it to make a new transaction with higher fees, how to do it please ?

Electrum is an SPV wallet, it does NOT broadcast transactions like a Full node. you make the transaction and then send it to an electrum node which is a full node and that broadcasts your tx to the network and your tx is now propagated throughout the bitcoin network and now all bitcoin nodes are "broadcasting" it

to bump fees you should have marked it as an RBF transaction so that you could easily bump the fees up.

Ok, thank you, so when will the node stop broadcasting the transaction ?

Ok, thank you, so when will the node stop broadcasting the transaction ?

theoretically in 2 weeks.
practically when it is confirmed or invalid. so never if your tx never confirms or becomes invalid (double spending for example).

this is because there is always going to be a node out there with your tx in its memory pool which will broadcast it again and it will propagate through the network again.
