Contract Deployment and Call

1. Build a Move Project:
   Create and build your Move project as usual.

2. Package the Contract:
   In the root directory of your Move project, run the following command to package and output the contract:

mpm release

This will generate a blob file in the ./release/ folder (e.g., xxx.blob).

3. Deploy the Contract:
   Open the Starcoin console and follow these steps:

• Import an Account:
  Use your private key to import an account (make sure it has STC):

  account import -i <0x private key>
  

• Deploy the Contract:
  Deploy your packaged contract with the following command (replace placeholders accordingly):

  dev deploy <path>/release/xx.blob -s 0x12345 -b
  

• View Deployment Results:
  Check the output in the console to verify successful deployment.

4. Call the Deployed Function:
   Execute the entry function of your deployed contract using this command (replace <ModuleName> and <FunctionName> with actual names):

account execute-function --function 0x123456:::: -s 0x12345 -b

5. View Call Results:
   Confirm the function execution by checking the call results in the console.
