Understand cost and permission separately

Ethereum learning involves more than recognizing an ETH balance. The guides here connect network selection, fee interpretation, token permissions, and transaction review. A low-looking cost is not proof that an action is appropriate, and a familiar address format is not a universal compatibility test.

Use the gas article for cost vocabulary and the approval article for permission scope. The multichain and sending guides help keep the destination context visible. Current details depend on the actual wallet, network, and application; DroidWallet provides education and proposed interfaces only.
