METASK: Sending transactions with signatures
As web developers, we often rely on various blockchain platforms to facilitate safe transactions between users. A popular choice is Metask, an easy-to-use interface for interaction with Ethereum blockchain. However, when it comes to sending transactions, a common limitation of Metask was frustrating by many users: the requirement to transmit transactions before signing them.
In this article, we will explore why Metask requires diffusion and how you can overcome this limitation using the Send function with a signature.
Why do you broadcast transactions?
Before you sink into the solution, let us understand why Metamans must broadcast transactions. When performing a transaction, it usually includes not only the value of the transferred asset, but also a unique identifier (address) associated with the sender and the receiver. To ensure that the transaction is valid in the blockchain network, these addresses must be broadcast throughout the network.
The broadcasting process involves the creation of a Merkle tree, which groups all transactions in a way that allows an efficient verification of the transaction validity. This process can be expensive from a calculated point of view and consumes time, which makes a provocative task for individual users for you to deal with significant resources or infrastructure.
Limitation: Sending transactions with signatures
Now let’s talk about why Metask requires broadcast first:
- Verification : To make sure that all transactions are valid and follow the rules set by the Blockchain (Ethereum) network, Metask must check them before being accepted.
- Merkle trees : As mentioned above, broadcasting helps create Merkle trees to check for transaction validity. This requires significant calculation and infrastructure resources.
Solution: Send your signature function
In order to overcome this limitation and allow users to send transactions without broadcasting them, Metask has introduced the function “with a signature in its last version (0.X).
Here’s how you can use it:
Sending transactions with signatures
To send a transaction using the Send function with a signature from the local wallet, follow these steps:
- Make sure you have metamark installed on your server.
- Go to the Metask application and select “Send” or click the “Send” button in the upper right corner of the interface.
- In “Send” mode, enter the transaction details:
* Sum
: Enter the value of the asset you transfer (in ETH).
* from : Select the sender’s address.
* to : Select the addressee address.
* Network : Choose -the network (for example, Ethereum Mainnet).
- In the “Signature” section, Metask will ask you to sign the transaction. To do this:
* Back to fashion Send and click” Sign “.
* Select “Use your account signature” or choose a previously signed transaction.
5.. The details of the transaction will be sent directly to the Ethereum network.
Conclusion
Using the “SEND” function of Metask with signature, you can send transactions from the local wallet without broadcasting them on the network. This approach is especially useful for small -scale development projects, where resources are limited or when working with blockchain applications that require easier solution.
Note that this is just one example and may require changes based on your specific use case. For more advanced solutions, you may want to explore other integration methods, such as interaction with Ethereum Mainnet directly through Javascript or using third -party libraries.
