ETH processing stopped due to high load on ETH network. Processing will resume when network load reduces. This is the message most exchanges are displaying. So how long will they clear backlog transactions. Will it be temporal or it will be happening here and there.
Set the gas and gwei of your transaction into a standard or higher value. It will give a chance to your transaction will be completed more faster.
Before i do on transaction, sometimes i check ethgasstationinfo to get morr information about eth traffic and gas valur for transaction
