METASK: FUNCTIONS DUE IN METASK
As a developer, interaction with smart contracts requires more than just a writing code; Also, it requires the management of your funds. One of the primary libraries for interaction with intelligent Ethereum contracts on the web is Metask. In this article, we will examine how to use the functions due in Metascus.
What are the features paid?
The payment characteristics, also known as appeal functions, allow you to take actions on a contract without transferring funds from the wallet. They are particularly useful in managing smart contracts that require the user’s introduction or performing specific actions, such as creating new wallets or sending transactions.
Using Metask with paid functions
Follow the next steps to use the proper functions in Metask:
1. Create a web3 supplier
Before you can interact with the contract with the due functions, you must configure a web3 supplier for Metask. You can do this according to the instructions on the Metask Documentation Page or you can create your own web3 supplier.
2. Install the Eéters.js library
If you want to use MetaScus with paid features, you must also install the Eéters.JS library that offers a simple and intuitive API interface to interact with Etreem smart contracts.
Here is an example of how to install eéters.js in your project.
`Bash
NPM Install the Eters
3. Create a contract with a payable function
Create a new contract that defines a paid function. In this example, we will create a contract called "MyContract" that allows users to send ETER to the contract.
Here are some sample code for the contract:
JavaScript
Const mycontract = {
Features: {{
Transfers: {
Inputs: [
{
Name: "from",
Type: "Address",
Mandatory: True,
},
{
Name: "to",
Type: "Address",
Mandatory: True,
},
{
Name: "value",
Type: 'uint256',
Mandatory: True,
},
]
},
},
};
In this example, the "Transferfunds" function has three arguments:
- From”: an address that receives the ether
All: an address that sends an ether
- Value: Height Etter
#####. Use Metask with a contract
To use the maturity function at Metask, you must create a new instance of the contract and hand it to the Web3 supplier.
Here is an example of code sketch:
`JavaScript
Import {web3} from 'web3';
Const web3 = new web3 ();
Contract Const = New MyContract ();
Web3.etth.accoun.sendtransction ({
From: Web3.etactsnts [0], // own account of Ethereum's own
to: Contract.address, // Contract Address
Value: Web3.utils.Towi ('1', 'eter'), // the amount sent to the ether
}, (error, transactions) => {
IF (error) {
Console.error (error);
} Else {
Console.log (successful transaction: $ {transactionhash});
}
});
Example of use
Here is an example of use that shows how to use the functions paid in Metask:
Suppose you have a contract called "MyContract" that allows users to send an ether in the contract. You will create a new instance of the contract and you will teach it to the web3 supplier:
` JavaScript
Import {web3} from ‘web3’;
Const web3 = new web3 ();
Contract Const = New MyContract ();
// create a new transaction
Treaty.Transferfunds ({
From: Web3.etactsnts [0], // own account of Ethereum’s own
To: Web3.ethaddresse [1], // another user address to blockchain
Value: Web3.utils.Towei (‘1’, ‘eter’), // the amount sent to the ether
}, (error, transactions) => {
IF (error) {
Console.error (error);
} Else {
console.
