Metamask approves the function: Guide for React Native Dapp Developers
As a react native developer, building decentralized applications (DAPP) from Ethereum, you probably encountered the Metamask approval function. The approval function is used to validate upcoming transactions in the Ethereum network before their implementation. However, when it comes to interaction with Metamask and signing transactions using the approved function, things can become a bit more complicated.
Error « Network requests »
When calling the « approval » function with DAPP, Metamask sends a request to the Ethereum network to confirm the transaction. This request is usually served by [Ethereum gas station] ( which can be influenced by various factors.
Common causes of errors « Network request »
Here are some typical reasons why you can see this error:
* Start a gas station : Ethereum gas station may experience technical problems, causing delays or failures of gas demand processing.
* Overloading the Ethereum network : High traffic in the Ethereum network can lead to increased delay and reduction of the success rates of the gas station demands.
* Problems with the signing address : Problems with the configuration of the Metamas account or portfolio configuration may prevent the correct operation of the approval function.
confirm the function by returning the values
After calling the function, they « approve » returns the value of integers, which indicates whether the transaction has been successfully approved. However, in some cases this value may be negative, e.g. « -32000 ». At the beginning it may seem misleading, but let’s immerse ourselves in what can cause this error.
Sign success vs. Network request failure
After calling the function, they « approve » returns the value of integers, which indicates whether the transaction has been successfully approved. However, in some cases this value may be negative, e.g. « -32000 ». At the beginning it may seem misleading, but here is what this mistake may cause:
* Success of signing : If the transaction is signed successfully using a private key or mnemonic, the « approved » function should return a positive integer (e.g. 0). However, if the problem arises when signing, such as a key collision or incorrect mnemonic format, this may cause a negative value (-32000).
* Network’s failure : If Metamask encounters problems with an Ethereum account or a portfolio configuration, it may not be able to send the required demands to the gas station. This can lead to errors and returning values such as -32000.
Railing out the problem
To solve this problem, you can try the following activities:
* Monitoring of the update gas stations : Keep an eye on the status and efficiency of the Ethereum gas station.
* Metamask’s configuration of the portfolio : Make sure that the Metamask account is correctly configured, with a correct private key or a mnemonic format.
* Tire DAPP thoroughly: Check if your DAP has been working properly, including the approval function and interaction of the gas station.
Understanding what this error can cause, you can take steps to solve it and ensure trouble -free transactions in the Ethereum network.
