METAMASK: Separate Ethereum suppliers for greater safety and control
As a developer that builds a decentralized application (DAPP) using Ethereum, one of the most critical components is user experience. A feature that can improve this experience is the user’s interaction through Metamask, the popular extension of the Ethereum wallet for web browsers. However, when it comes to interacting with the intelligent contracts of your DAPP in Ethereum, you may wonder if you need an Ethereum supplier separate from MetamSk.
In this article, we will deepen the world of Ethereum suppliers and explore why using a separate one may not be necessary, even when using MetamSk for user interactions.
The predetermined Ethereum supplier
When you install Metamk’s extension on your web browser, it comes with an integrated Ethereum supplier that allows users to interact with the smart contracts of their DAPP. This default provider is generally configured to use the Ethereum node API, which is an API based on Rest that connects directly to the Ethereum network.
The benefits of using a separate supplier
The use of a separate Ethereum supplier can offer several advantages:
- Improved security : When using a separate provider, you have more control over the interactions of your intelligent contract, including authentication and authorization. This can help prevent unauthorized access and data violations.
- Improved user experience
: When separating Metamk interaction, you can design a perfect user interface that does not require users to nave to an external page or click a button to interact with your wallet.
- A better integration with the DAPP code base : The use of a separate provider allows you to integrate it directly into the Smart Contract Code of your DAPP, ensuring that interactions are handled efficiently and safely.
Why Metamk can still work well with a separate supplier
While the use of a separate Ethereum supplier offers several benefits, there are scenarios in which it prefers to use the default metamash provider:
- Ease of use : If your user interface is simple or does not require advanced interaction functions, the simplicity of the default provider could be sufficient.
- Inherited applications : If you are creating an application that is based on previous versions of Ethereum (for example, 1.x) and has not yet migrated to newer versions, using the default provider could be the most direct approach It could be the most direct approach. .
Conclusion
In conclusion, although the use of a separate Ethereum supplier can offer several benefits to improve safety, better user experience and better integration with the DAPP code base, there are scenarios in which you prefer to use the predetermined Metamk . When choosing between the two, consider the specific needs of its application, the existing infrastructure and the compensation between the ease of use and the advanced characteristics.
Example of code
Here is an example of how you could integrate a separate Ethereum provider into its DAPP using solidity:
`SOLIDITY
Pragma solidity ^0.8.0;
Mydapp contract {
// Define a function to interact with the external contract
interact function () public {
Require (msg.sender == address (this), "only the owner of the wallet can perform this action");
// Use the separate Ethereum supplier to interact with the contract
REQUIRE (ISCONTRACT (contractaddress), "the contract is not implemented");
Contract (contractaddress) .call (value: msg.value);
}
}
In this example, we define aninteract` function that uses the predetermined Ethereum supplier to call an external contract. The separate Ethereum provider can be used importing in the Smart Contract Code of its DAPP and calling the functions directly from there.
