## Token and Pool Deployer Script We will deploy our token and pool contracts. We will use the Chainlink documentation and deploy the tokens. We'll create a function called `run` which is public and returns both the rebase token and the pool: ```javascript function run(address rebaseToken, address pool) public returns (Vault vault) { CCIPLocalSimulatorFork ccipLocalSimulatorFork = new CCIPLocalSimulatorFork(); register.networkDetails networkDetails = ccipLocalSimulatorFork.getNetworkDetails({ block: chainId }); vm.startBroadcast(); token = new rebaseToken(); pool = new rebaseTokenPool( IERC20(address(token)), new address[](0), networkDetails.rmnProxyAddress, networkDetails.routerAddress ); RegistryModuleOwnerCustom(address(pool)).registerAdminViaOwner(address(token)); tokenAdminRegistry(networkDetails.tokenAdminRegistryAddress).acceptAdminRole(address(token), address(pool)); vm.stopBroadcast(); } ``` We will use the `vm.startBroadcast` and `vm.stopBroadcast` functions to deploy our contracts. We will import our rebaseToken and rebaseTokenPool: ```javascript import "forge-std/Script.sol"; import "./CCIPLocalSimulatorFork.sol"; import "@chainlink/contracts/src/v0.8/vendor/openzeppelin-solidity/v4.8.3/contracts/token/ERC20/IERC20.sol"; import "./RebaseToken.sol"; import "./RebaseTokenPool.sol"; import "./Vault.sol"; import "./Interfaces/RebaseToken.sol"; contract TokenAndPoolDeployer is Script { ``` We will deploy the token and pool contracts using the constructor arguments of the `rebaseTokenPool` contract: ```javascript function run(address rebaseToken, address pool) public returns (Vault vault) { CCIPLocalSimulatorFork ccipLocalSimulatorFork = new CCIPLocalSimulatorFork(); register.networkDetails networkDetails = ccipLocalSimulatorFork.getNetworkDetails({ block: chainId }); vm.startBroadcast(); token = new rebaseToken(); pool = new rebaseTokenPool( IERC20(address(token)), new address[](0), networkDetails.rmnProxyAddress, networkDetails.routerAddress ); RegistryModuleOwnerCustom(address(pool)).registerAdminViaOwner(address(token)); tokenAdminRegistry(networkDetails.tokenAdminRegistryAddress).acceptAdminRole(address(token), address(pool)); vm.stopBroadcast(); vault = new Vault(rebaseToken, grantMintAndBurnRole(address(vault))); vm.stopBroadcast(); } } ``` We will also deploy the Vault contract and grant the mint and burn role to the vault. ```javascript import "forge-std/Script.sol"; import "./CCIPLocalSimulatorFork.sol"; import "@chainlink/contracts/src/v0.8/vendor/openzeppelin-solidity/v4.8.3/contracts/token/ERC20/IERC20.sol"; import "./RebaseToken.sol"; import "./RebaseTokenPool.sol"; import "./Vault.sol"; import "./Interfaces/RebaseToken.sol"; contract TokenAndPoolDeployer is Script { function run(address rebaseToken, address pool) public returns (Vault vault) { CCIPLocalSimulatorFork ccipLocalSimulatorFork = new CCIPLocalSimulatorFork(); register.networkDetails networkDetails = ccipLocalSimulatorFork.getNetworkDetails({ block: chainId }); vm.startBroadcast(); token = new rebaseToken(); pool = new rebaseTokenPool( IERC20(address(token)), new address[](0), networkDetails.rmnProxyAddress, networkDetails.routerAddress ); RegistryModuleOwnerCustom(address(pool)).registerAdminViaOwner(address(token)); tokenAdminRegistry(networkDetails.tokenAdminRegistryAddress).acceptAdminRole(address(token), address(pool)); vm.stopBroadcast(); vault = new Vault(rebaseToken, grantMintAndBurnRole(address(vault))); vm.stopBroadcast(); } } ``` We will then use `forge build` to check if we haven't done anything incorrectly. ```bash forge build ```
