Metamask limitations on method calls: Understanding Contract Execution Speed ​​

When interacting with a decentralized application (DAPP) built on a blockchain, such as ethereum, using the metamask browser extension is crucial. However, one of the limitations you might encounter when relying heavily on contract.methods.some_method.call () to read data from your dapp’s contracts is understanding how can be called and what potential implications this has for the application.

Reading Data With Contract.Methods.Some_Method.Call ()

In general, calling a contract method within a script executed by metamask or other external code execution environments (e.g., remix) will incur some overhead due to the following reasons:

• Gas ​​: The gas fees associated with executing ethereum transactions and method calls can be substantial.

• Network latency : Data Transmission Between Metamask’s Javascript Environment, The Blockchain Network, and the Dapp’s Smart Contracts occurs at a certain speed.

The Specific Gas Cost Depends On Various Factors, Including:

• Contract Complexity (More Complex Contracts Require More Gas)

• Congestion Network

• The Amount of Data Being Read

To give you an idea, here are some rough estimates for reading different amounts of data:

| Data read | Estimated gas cost |

| : ——– | : ——————— |

| 100 bytes | ~ 15-25 Gwei (0.0000125 ETH) |

| 1KB | ~ 50-70 GWEI (~ 0.0045 ETH) |

| 10KB | ~ 150-250 GWEI (~ 0.0149 ETH) |

Blacklisting or Blocking Applications

While metamask is a powerful tool, excessive method calls can impact the performance of your dapp and potentially lead to blacklisting or blocking from the application’s developers.

Here are some reasons why this might happen:

* Overwhelming method call rate : If you are calling methods too frequently, the network may become congested, leading to increased latency.

* Gas ​​fees exceeding available funds : Excessive gas spending can deple your metamask balance or other ethereum accounts, making it difficult for you to continue using the application.

To mitigate these risks, consider the following best practices:

1. Use Async/Await andTry/Catch Blocks

When interacting with dapps’ contracts, use asynchronous programs techniques to avoid blocking the current thread while waiting for method calls or executing contract code.

`JavaScript

Const result = await yourcontract.methods.somemethod.call ();

2. Optimize method calls

To Reduce Gas costs and network latency:

• Minimize Complex Contracts: Fewer Complex Contracts Require Less Gas, Resulting in Lower Average Fees.

• Use a more efficient data format (e.g., buffer instead of plain javascript arrays).
