Today I’ll learn a piece of encryption knowledge: gas fees. When you transfer tokens, swap, or mint an NFT on-chain, essentially you’re asking the nodes to execute the actions for you. Gas fees are the network fees you pay for that execution. The more congested the network is, the higher the fee may be. Newcomers, remember: before transferring, confirm the chain, the address, and the gas fee; if you can wait, avoid peak times; try a small transfer first—don’t send all your funds at once.
