Users need to pay gas fees to make any transaction on the blockchain. Therefore, users must have enough balance to cover the cost of gas fees in their wallets. In many Web3 apps, users make such a mistake regularly by depositing the full amount and not having anything left over to make more transactions. However, when users make a transaction on the Balancer application, they get a warning message reminding them to leave some amount in their wallet to pay the gas fees. This little warning is a lovely touch to help users not make that mistake and keep them on the happy path.
