Each Sui project has a Move.lock file, which contains the deployment address of your package. You need to use this address for your specific network to ensure your Move.toml file correctly references the deployed package . If you're dealing with a deployed coin, you could manually obtain the source code from a blockchain explorer to use locally if the repository isn't publicly available. This way, you point to the local code in your Move.toml and set the package's address as per its mainnet deployment .

To import a deployed package, you need to ensure that the package is properly specified as a dependency in your Move.toml file. This can involve adding a local path to where you have the package's code or a git repository link if it's available online. If the package is on-chain, you might need to have a local copy of the package's code since the Move compiler requires the source code to correctly compile and verify dependencies .
