+# Bridge-related deployment scripts
+This process is the same as described in the original deployment procedure: [deployment](https://github.com/valory-xyz/autonolas-governance/blob/main/scripts/deployment).
+
+## Steps to engage
+The project has submodules to get the dependencies. Make sure you run `git clone --recursive` or init the submodules yourself.
+The dependency list is managed by the `package.json` file, and the setup parameters are stored in the `hardhat.config.js` file.
+Simply run the following command to install the project:
+```
+yarn install
+```
+command and compiled with the
+```
+npx hardhat compile
+```
+
+Create a `globals.json` file in the root folder, or copy it from the file with pre-defined parameters (i.e., `scripts/deployment/bridges/base/globals_base_sepolia.json` for the chiado testnet).
+
+Parameters of the `globals.json` file:
+- `contractVerification`: flag for verifying contracts in deployment scripts (`true`) or skipping it (`false`);
+- `useLedger`: flag whether to use the hardware wallet (`true`) or proceed with the seed-phrase accounts (`false`);
+- `derivationPath`: string with the derivation path;
+- `gasPriceInGwei`: gas price in Gwei;
+- `L2CrossDomainMessengerAddress`: (Base) CFM Contract Proxy address serving as a system processor of inbound calls across the bridge;
+- `timelockAddress`: Timelock address on the root L1 network;
+
+The script file name identifies the number of deployment steps taken up to the number in the file name.
+
+Export network-related API keys defined in `hardhat.config.js` file that correspond to the required network.
+
+To run the script, use the following command:
+`npx hardhat run scripts/deployment/bridges/script_name --network network_type`,
+where `script_number_and_name` is a script number and name, i.e. `deploy_01_home_mediator.js`, `network_type` is a network type corresponding to the `hardhat.config.js` network configuration.
+
+## Validity checks and contract verification
+Each script controls the obtained values by checking them against the expected ones. Also, each script has a contract verification procedure.
+If a contract is deployed with arguments, these arguments are taken from the corresponding `verify_number_and_name` file, where `number_and_name` corresponds to the deployment script number and name.
+
+## Data packing for cross-bridge transactions
+In order to correctly pack the data and supply it to the Timelock such that it is correctly processed across the bridge,
+use the following script: [cross-bridge data packing](https://github.com/valory-xyz/autonolas-governance/blob/main/scripts/deployment/bridges/pack-data.js).
