Gas is the internal pricing for running a transaction or contract in the Ethereum network. Every operation that can be performed by a transaction or contract on the Ethereum platform costs a certain number of gas, with operations that require more computational resources costing more gas than operations that require few computational resources.

The reason gas is important is that it helps to ensure an appropriate fee is being paid by transactions submitted to the network. By requiring that a transaction pay for each operation it performs (or causes a contract to perform), it ensure that network doesn't become bogged down with performing a lot of intensive work that isn't valuable to anyone.

When it comes to actually paying for the gas, the transaction fee is charged as a certain number of ether, the built-in token on the Ethereum network and the token with which miners are rewarded for producing blocks.

Gas is the way that fees are calculated. Gas is the execution fee for every operation made on the ethereum network. Its price is expressed in ether and it's decided by the miners, which can refuse to process transaction with less than a certain gas price. To get gas you simply need to add ether to your account.

A TX-ID is a transaction ID in the blockchain which you can find in the transaction history of your wallet. A TX-ID is used to find your transaction in the blockchain.

Some of the transaction made on Neufund platform by the users are being mined on the blockchain therefore it require the user to pay Gas FOR IT. It means that your Neufund account need to have a certain amount of ETH to cover the Gas cost for transaction made on our Platform.
