In the past, the Ether Workshop has been a long way from being a very long time-consuming transaction.
In the Ethelium network, Gas It is the unit that measures the workload required to carry out a particular operation. Since the Ether's space is a limited resource, the network is busy (e.g., hot doors) When NFT found or market was volatile) users needed to bid for higher Gas prices (in Gwei) (e) Ensure that transactions are packed as a priority by miners/certifiers.
Specific pain points to be addressed by the Gas Calculator
- Avoiding transaction failure: Many users failed the transaction because of the set Gas Limited low, but the transaction failed, but Gas The fee will still be deducted. This tool helps you lock up safe Gas Limited by pre-seting common types of transactions.
- Real-time cost conversion: How much is Gwei? For ordinary users, the units of ETH are very abstract. This tool converts ETH to USDT in real time And cny, give you a visual sense of the real cost of every deal.
- Seize the low peak time: By simulating different Gas prices, you can predict that if you wait until the network is free (e. g. Gas down to 15) How much cost savings can be achieved by operating at the Gwei.
Gas Cost formula
The transaction fee formula is:
Total Fee = Gas Price * Gas Limit
- Gas Price (Gwei): You're willing to pay the price for each unit Gas. 1 Gwei = 0.000000001 ETH。
- Gas Limit: The transaction allows the largest amount of Gas consumed. (b) Normal ETH transfers are fixed at 21,000; Smart contracts are much more complex to interact with.
How to save Gas costs? Professional advice
Using Gas Tracker: Before conducting non-emergency operations (e.g., receiving airdrops, returning tokens), observe Gas movement, usually on weekends or UTC The hour of dawn is low peak.
2. Use of the L2 network: Consider using Arbitrum, Optimism or Base if the network is too high The second tier extension usually costs only one tenth or even less of the main network.
3. Batch processing transactions: Some tools support the sending of multiple addresses by one key, which saves considerable base Gas costs compared to multiple copies.
Contexts for addressing specific issues
Scene one: Participation in hot projects. When a hot NFT starts casting, the network Gas could jump to hundreds in a flash. Gwei。 Use this calculator to quickly calculate how much you need to pay if you set 300 Gwei ETH, thereby determining whether the project is worth participating in.
Scene 2: DEX trade hedge. When trading small assets on Uniswap, if Gas fees exceed the amount of the transaction 5 per cent, the transaction is not financially profitable. The calculator will help you quickly identify this "negative game."
Scenario III: The balance of the wallet is not a reminder. Many times the transaction was not issued because the balance was not sufficient to cover Gas. Precalculate the required ETH to ensure that the accounts are adequate Buffer。
