# Deploy a Solidity Smart Contract
## Overall
In this tutorial, we will learn how to deploy a [**Solidity** Smart Contract](https://docs.soliditylang.org/en/latest/introduction-to-smart-contracts.html) on the CESS blockchain. Solidity smart contracts are widely deployed on EVM-compatible chains, notably Ethereum. CESS blockchain is also EVM-compatible and allows Solidity developers to deploy their contracts on CESS with no or minimal changes.
## Preparation
You will need the following to deploy a Solidity smart contract to CESS.
* **MetaMask**: Required to get an Ethereum address and to connect to the CESS chain
* **CESS Acount**: Refer to [this article](https://github.com/CESSProject/doc-v2/blob/main/community/cess-account.md) on how to create a CESS account and [this article](https://github.com/CESSProject/doc-v2/blob/main/developer/guides/testnet-faucet.md) on getting testnet tokens from our faucet.
* **Remix IDE**: Access to [Remix IDE](https://remix.ethereum.org/) to develop, compile, and deploy smart contracts to the chain
* **Access to CESS Node**: Make sure the node allows access from MetaMask.
The following steps will guide you to deploy a Solidity contract on the CESS testnet.
{% hint style="info" %}
This tutorial involves working with the EVM in CESS test-chain. You will understand better if you understand the reasoning and mechanism behind the [Subtrate and EVM address conversion](https://github.com/CESSProject/doc-v2/blob/main/developer/guides/substrate-evm.md).
{% endhint %}
## Add CESS Network to MetaMask
Open the MetaMask setting tab, click on the **Networks** tab, click on **Add a network** and then **Add a network manually**.
On **Add a network manually** page, enter the following details:
* Network Name: **CESS Testnet**
* New RPC URL, one of the following:
*
* Chain ID: **11330**
* Currency Symbol: **TCESS**
## Convert the Substrate Address to an EVM Address
Copy the account address from MetaMask.
Open the page to [Substrate Address Converter](https://hoonsubin.github.io/evm-substrate-address-converter).
Input the following:
* Current Address Scheme: **H160**
* Change Address Prefix: \**11330*
* Intput address: *your metamask account*
* Copy the account address starting with "cX.."
Get the EVM address output.
## Fund the Account
Using [CESS Explorer](https://testnet.cess.network/) **Accounts -> Transfer** to transfer some balance to the Substrate address output above. For testnet goto [testnet faucet](https://cess.network/faucet.html) to get fund drip into this Substrate address.
## Validate the Fund
To validate the funds are in the Ethereum account, open MetaMask and check that account has the funds transferred
## Deploy a Contract Using Remix IDE
{% hint style="info" %}
You can use one of the [sample Solidity smart contract codes here](https://github.com/CESSProject/cess-examples/tree/main/hardhat).
{% endhint %}
Open [Remix IDE](https://remix.ethereum.org/) and go to **File explorer**.
In File explorer, open the smart contract you wish to compile and then deploy.
Once the file is selected, go to tab **Solidity Compiler**, you should see the selected file, press the **Compile** button to compile the contract. Once compiled, you’ll see the "green tick" mark and compiled (\*.sol) file.
Go to **Deploy and run Transactions**, once the compilation is successful, you should see the compiled \*.sol file selected, ready to be deployed. In the **Environments** drop-down, select **Injected Provider - MetaMask** and click **deploy**.
{% hint style="info" %}
When you click **Deploy**, you will need to confirm in MetaMask to allow Remix to access the account and submit the transaction.
{% endhint %}
Click **Confirm** to submit the transaction to deploy the smart contract.
After the transaction is deployed and processed on-chain, you’ll see the following message.
In the **Deployed Contracts** section in the Remix, you can call the function of the smart contract.
## Transfer Tokens to the CESS Account
Convert the Substrate address to Ethereum account address using the link [Substrate Address Converter](https://hoonsubin.github.io/evm-substrate-address-converter).
Copy the Ethereum equivalent address and use MetaMask to transfer fund.

Transfer Fund in Metamask 1

Transfer Fund in Metamask 2

| -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
Confirm the balance in the [CESS Explorer: Developer RPC calls](https://testnet.cess.network/#/rpc). Use the Ethereum address in previous step.
## Withdraw Balances to the CESS Account
To withdraw the balance from the Ethereum account to CESS account, follow the route **Developer => Extrinsics => evm => withdraw**.
Validate the balances in **Accounts** tab of CESS Explorer.
