Transactions are written on the blockchain by people called miners and secured by validators. Most normal people like us don’t actually interact with the blockchain directly; rather, a miner does it on our behalf in exchange for a small fee called Gas. In this article, we’ll talk about setting custom gas fees: what they are and how to change them. For additional resources, please check out our Gas Fees Explained article.
Rainbow predicts the gas price for you:

Setting custom gas prices:
