Metamask: Metamsk Payment Functions
As a developer, interacting with intelligent contracts requires more than the Writing Code; It also requires managing your funds. One of the main libraries to interact with Ethereum’s intelligent web contracts is Metamsk. In this article, we will explore how to use functions to pay in Metamsk.
What are the payment functions?
The functions to be paid, also known as call functions, allow us to perform shares in a contract without transferring funds from your wallet. They are particularly useful for managing intelligent contracts that require user entry or performing specific actions, such as creating new wallets or sending transactions.
Use of metamk with payment functions
To use the payment functions in Metamsk, follow these steps:
1. Create a web3 supplier
Before you interact with a contract that uses functions payable, you must configure a web 3 supplier to Metamsk. You can do this by following the instructions on the Metamk documentation page or creating your own custom web supplier.
2. Install the Ethers.js library
To use Metamsk with functions payable, you will also need to install the Ethers.js library, which provides a simple and intuitive API to interact with Ethereum’s intelligent contracts.
Here is an example of how to install ether.js in your project:
`Bash
NPM Install ÉTERS
3. Create a function contract to pay
Create a new contract that defines a function to pay. In this example, we will create a contract called 'Mycontract' that allows users to send ether to the contract.
Here is some sample code for the contract:
JavaScript
CONST MYCONTRACT = {
Functions: {
Transferfunds: {
Tickets: [
{
Name: 'de',
Type: 'Address',
Required: True,
},
{
Name: 'A',
Type: 'Address',
Required: True,
},
{
Name: 'Valor',
Type: 'Uint256',
Required: True,
},
]
},
},
};
In this example, thetransferfundstakes three arguments:
- De ‘: the address you will receive ether
Para: the address that will send ether to
VALUE: The amount of ether that is transferred
4. Use metamask with the contract
To use the payment function on Metamk, you must create a new contract instance and pass it to the Web3 supplier.
Here is a Fragment of Example Code:
`JavaScript
Import {Web3} of 'Web3';
CONST WEB3 = New Web3 ();
CONTT CONTRACT = new mycontract ();
Web3.eth.acounts.sendtransaction ({{
From: Web3.ethacounts [0], // your own Ethereum account address
A: Contract.ddress, // Contract management
Value: Web3.utils.Towei ('1', 'ether'), // the amount of ether that is sent
}, (Error, transactionhash) => {
if (error) {
Console.error (error);
} others {
Console.log (successful transaction: $ {transacthonhash});
}
});
Example of use
Here is a case of an example of use that demonstrates how to use the payment functions in Metamsk:
Suppose you have a contract calledmycontractthat allows users to send ether to the contract. You create a new instance of the contract and pass it to the web3 supplier:
` JavaScript
Import {Web3} of ‘Web3’;
CONST WEB3 = New Web3 ();
CONTT CONTRACT = new mycontract ();
// Create a new transaction
Contract.transferfunds ({{
From: Web3.ethacounts [0], // your own Ethereum account address
A: Web3.Eetaddresses [1], // The address of another user in the block chain
Value: Web3.utils.Towei (‘1’, ‘ether’), // the amount of ether that is sent
}, (Error, transactah) => {
if (error) {
Console.error (error);
} others {
console.
