To deploy a smart contract on Satschain using the DApp, you need to follow several detailed steps to ensure a smooth and successful deployment process. Here’s a comprehensive guide to help you through each stage of the process:
Prerequisites
Before you begin interacting with smart contracts on Satschain, ensure you have the following:
A compatible wallet (e.g., Unisat) installed and set up.
Some Satschain tokens in your wallet to cover transaction fees, if you are not using 0 Gas Price.
Access to the Satschain explorer and DApp interfaces over the internet.
Step 1: Setup Wallet and Connect
First, ensure you have a compatible wallet like Unisat installed. Unisat is essential for interacting with the Satschain DApp. Once you have Unisat, connect your wallet to the Satschain DApp by selecting the appropriate network (only testnet as of now) and authorizing the connection. This connection is crucial as it allows you to manage transactions and interact with the smart contracts.
Step 2: Access Deployment Interface
Navigate to the Satschain DApp. Look for the option labeled "Deploy Smart Contract." This will take you to the deployment interface where you can start the process of writing and deploying your smart contract.
Step 3: Write Your Smart Contract
In the deployment interface, you will find a code editor. Here, you can write your smart contract using Solidity, the programming language supported by the EVM (Ethereum Virtual Machine) on Satschain. Solidity is a high-level language designed for implementing smart contracts. Make sure your contract logic is well-defined and tested before moving on to the next step.
Step 4: Compile the Contract
Once your contract is written, use the built-in compiler provided by the DApp to compile the contract. Compilation is a critical step as it ensures that your code is free from syntax errors and is converted into bytecode that the EVM can execute. If there are any errors, the compiler will highlight them, allowing you to make necessary corrections.
Step 5: Set Deployment Parameters
After successful compilation, you need to set the parameters for deployment. This includes:
Constructor Parameters: If your contract constructor requires parameters, you need to provide them here, right after compilation. And then click “Create Contract JSON”.
Now you will see the JSON that will get inscribed. Here you have an option to modify Gas Limit and Gas Price.
Gas Limit: The maximum amount of gas you are willing to spend on the transaction. By default this value is set to hexadecimal 30 million. You may modify it if your contract is complex enough.
Gas Price: The amount of SACHs you are willing to pay per gas unit usage. Currently Satschain allows you to run transactions with 0 Gas Price.
Step 6: Sign Your Transaction
With your parameters set, the next step is to sign the transaction. In the Unisat wallet, you will receive a prompt to sign the transaction. This step ensures that the transaction is authorized by the wallet owner and ready for processing on the network. For technical users, we sign the RLP encoded transaction (with signature field empty).
Step 7: Inscribe Your Transaction
After signing, you need to inscribe your transaction. This involves setting a viable fee rate (in sat/vbytes) and then clicking the inscribe button. The Unisat will again prompt you with a dialog box, inquiring if you want to sign the order. Click the sign button and you are done. The DApp will then generate the inscription ID and the contract creation address. The inscription ID is a unique identifier for your transaction, while the contract creation address is where to find your smart contract on the Satschain state tree.
Step 8: Confirm and Verify
Once the transaction is confirmed, your smart contract will be deployed on the Satschain. You can verify the deployment by checking the transaction details on the Satschain explorer. Navigate to the contract address using the link provided by the DApp and verify the contract source code to ensure everything has been deployed correctly.
By following these detailed steps, you can successfully deploy a smart contract on Satschain using the DApp, ensuring a smooth and efficient process from start to finish.
