Why did my transaction fail on MetaMask?

In the realm of blockchain transactions, gas serves as a fundamental component that fuels the execution of operations on the network. Each transaction incurs a specific cost in terms of gas.

The total cost of a transaction is determined by multiplying the amount of gas required by the gas price set by the user. This calculation is crucial as it reflects the economic cost associated with performing the transaction.

If the resultant total, when converted to the network's native currency, exceeds the balance available in your wallet, the transaction will fail due to insufficient funds. This situation commonly arises when users underestimate the gas requirements or set an unrealistic gas price.

To avoid such occurrences, it is advisable to carefully estimate the gas needed for your transaction and ensure that your wallet holds sufficient funds to cover the total cost. BTCC, as a top cryptocurrency exchange, offers a range of services that can assist in this process. Their platform includes spot trading, futures trading, and a secure wallet, among others, all designed to enhance the user experience and facilitate seamless transactions.

When sending a transaction and encountering failure, the primary reason often stems from insufficient gas. This scenario can be likened to "running out of gas" during the process.
