Metamk goals Methods Related Descriptions: Understanding the Execution of the Contract
When you interact with a decentralized program (DAPP) built into a block circuit such as Ethereum, it is very important to use the Metamask browser extension. However, one of the restrictions you can find by trusting the large Contract.Methods.Mmethod.call () program.
Data reading using Contract.methods.method.call ()
In general, calling the contract method in the script made by the Year or other external code enforcement environment (such as Remix) will result in some total cost:
1
- Network Delay : Data transmission between Metamk JavaScript environment, DAPP Intelligent contracts are at a certain speed.
Specific gas prices depend on several factors including:
- The complexity of the contract (the most complex contracts require more gas)
- Network congestion
- The quantity of the data you read
To provide an idea, there are some approximate estimates to read different quantities of data:
| Reading data | The cost of the gas is expected
| : ——- | : ————— |
| 100 bytes | ~ 15-25 Gwei (0.0000125 ETH) |
| 1 KB | ~ 50-70 Gwei (~ 0.0045 ETH) |
| 10 KB | ~ 150-250 Gwei (~ 0.0149 ETH) |
Black List programs or block
While Metamk is a powerful tool, excessive methods can affect its DAPP performance and potentially cause a blacklist or program developer block.
Here are some reasons why this can happen:
* The overall method of the method of the method
: If you call the methods too often, the network can be overcrowded, leading to a greater delay.
* Gas rates that exceed available funds : Excessive gas costs can use your metamash balance or other Ethereum accounts, making it difficult to continue using the program.
To soften this risk, consider the following best practice:
1. Use Async/Waiting and Catch blocks
When communicating with DAPPS contracts, use asynchronous programming methods to prevent the current thread blocking waiting for a method of calling or execution of the contract code.
`JavaScript
CONTS score = wait for your Contract.Methods.somemethod.call ();
2. Optimize the method calls
Reduce gas consumption and network delay:
- Reduce complex contracts: less complex contracts require less gas, which reduces average.
- Use a more efficient data format (for example, a buffer than a simple JavaScript matrix).
