In this tutorial, we will learn how to deploy a 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.
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 on how to create a CESS account and on getting testnet tokens from our faucet.
Remix IDE: Access to 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.
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
Copy the account address from MetaMask.
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.
To validate the funds are in the Ethereum account, open MetaMask and check that account has the funds transferred
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.
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.
Copy the Ethereum equivalent address and use MetaMask to transfer fund.
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.
Open the page to .
Using Accounts -> Transfer to transfer some balance to the Substrate address output above. For testnet goto to get fund drip into this Substrate address.
You can use one of the .
Open and go to File explorer.
Convert the Substrate address to Ethereum account address using the link .
Transfer Fund in Metamask 1
Transfer Fund in Metamask 2
Confirm the balance in the . Use the Ethereum address in previous step.
