在 Web3 中， gas 是指在區塊鏈網絡上執行交易的成本。 當用戶啟動交易時，他們會包括一筆費用來支付將交易記錄到區塊鏈的成本。 Gas 費用 通常 以網絡的原生貨幣支付。 

Why do I see an `Insufficient balance` error?

Even if you have enough of the token you're trying to send or interact with, you'll still need the native token of the blockchain to cover the gas fees. If you're encountering the Insufficient balance message, you'll need to fund the wallet with the native token to cover transaction costs. For example, you use ETH on the Ethereum Network and SOL on the Solana network to pay for gas and complete a transaction.

You can fund your wallet and resolve the Insufficient balance error a few different ways:

• Funding through an on-ramp provider. 
• Depositing funds from another wallet or exchange.
• Bridging funds from another chain/network. 

Editing the gas fee

The gas required to execute a transaction can vary depending on the network, level of congestion, and complexity of the transaction. Brave Wallet automatically calculates the suggested gas price needed to complete a transaction.

The Max priority fee can be changed to potentially increase your transaction speed. While not a guarantee, miners will likely prioritize your transaction if you pay a higher fee.

There are some risks with manually adjusting gas fees, such as setting the gas fee too low. The transaction could take awhile to process or fail altogether.
