Connect to ShimmerEVM Testnet and deploy a Solidity Smart Contract

Prerequisites​

• Metamask or any other wallet of your choice.
• Remix or any other development environment of your choice.

Connect to ShimmerEVM Testnet​

You can either just use the following button to add the ShimmerEVM Testnet network to Metamask or enter the information manually.

To add the ShimmerEVM Testnet network manually to your Metamask use following info:

• Network Name: ShimmerEVM Testnet
• New RPC URL: https://json-rpc.evm.testnet.shimmer.network
• Chain ID: 1073
• Currency Symbol: SMR
• Explorer URL: https://explorer.evm.testnet.shimmer.network

Alternatively, you can setup your own EVM Smart Contract Chain on top of the Shimmer network and provide a custom URL, which might look something like: https://api.sc.testnet.shimmer.network/chain/rms1prr4r7az8e46qhagz5atugjm6x0xrg27d84677e3lurg0s6s76jr59dw4ls/evm/jsonrpc as well as your own custom Chain ID.

Hit Save and wait for Metamask to connect to the network.

At this point, our Metamask wallet is connected to the Shimmer EVM Testnet, but we don't have any funds in it. So, let's try to get some.

Get EVM Account Funded​

Open EVM Toolkit and enter your EVM address as shown below:

In case, you've setup a custom EVM chain, you'd need to add your custom network first. Please add your own chain address and select the relevant network as shown below:

Once you're done, click on Send funds and wait for a few minutes for the faucet to process. You should start seeing some funds on your Metamask wallet soon.

Now, open Remix ide or your favourite IDE and let's try to deploy a solidity smart contract.

Deploy Solidity Smart Contract​

Here's a sample solidity smart contract that we will be deploying:

// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;
contract Storage {
    uint256 number;
    function store(uint256 num) public {
        number = num;
    }
    function retrieve() public view returns (uint256){
        return number;
    }
}

If you've a different smart contract that you wish to deploy, feel free to.

Go to the Run tab and Select Injected Provider - Metamask as your environment as shown below:

Then, click on Deploy and confirm the Metamask transaction as shown below:

And voila—it's done!
