ovasscript
cont Web3 = require(’web3’);
const Web3Contrat = require(wb3-ethereum-contects’);
Class MySmartContrac class {
entrepreneurs() {
this.web3 =web3(new Web3. Providers.HtpProadps://ropsten.inflow.o/v3/YOUR_PROJECT_ID’));
concert contractAdress = ‘0xYurContractAdredress’;
contest contract = = {“ ”: "name": "name": "name": "MyContract”, "function"]: ["myFunction"]};
this.contracts = be Web3Contrac3, contractAddress, contractor);
}
myFunction() {
// Call the form of deployment
console.log("Hello is a meFunction!");
}
}
module.exports = MySmartContrac;
s
**Step 3: Compley and deploy your your smartness.
Create a slot called.js’ and add the following code:
const Truffle = require(’treffle’);
module.exports = {
compile() {
returned new Trufflesow();
}
^
s
Step 4: Use Truffle your entrepreneurs of Ropsten
*
Run the following in your terminal:
! you'
pum compile
s
This wll create and compiled version of the smart. Tan, use Truffle to migrant it from Ropsten:
! you'
ruffle migrants --et work ropsten
s
Step 5: Update your Metamask account
Update your is metamask.js’ file with the following configuration:
ovasscript
constinent Metamassk = require(’memass’);
consent rostenAdress = "0xYourRopsenAccount";
constentlyPassword = "
module.exports = {

module.exports = {
mnemonic: ropstenPasword,
network: {
ropste: {
addressing: ropsteAdress,
password: ropstePasword,
}
}
^
s
Error mesage
What you run a migrant migration --tework ropste, you will hold a simulated error to this:
