 ## Connecting the Safe Client Gateway (CGW) to the Safe Transaction Service (TXS)
 
 The CGW can forward requests to many independently running TXS instances pointing to different chains. The CFG has to keep a registry of every available instance of the TXS.

 We need to be able to define a `ChainInfo` object in the Safe Config service so that the Client Gateway knows the URL of the Safe Transaction service instance it needs to request against for a given safe.

 You can verify that your `ChainInfo` was successfully added by going to `http://localhost:8000/cfg/api/v1/chains`.
 
 Remember to edit your `ChainInfo` json fields `transaction_service_uri` and `vpc_transaction_service_uri` to point to your local instance of the transaction service. The values should be `http://nginx:8000/txs`

 Add your `NEXT_PUBLIC_INFURA_TOKEN` value if its required for the chain RCP uri in the [container_env_files/ui.env](../container_env_files/ui.env) file.
 
 Additionally, the Safe Web app itself, defines which instance of the Safe CGW to use in this [container_env_files/ui.env](../container_env_files/ui.env) file. The value of `NEXT_PUBLIC_GATEWAY_URL_PRODUCTION` defines the URL where the Safe CGW can be reached. The default in this repo, points to the instance running as part of the `docker-compose.yml` file, but can be adjusted to point to our production instances, or your own hosted instance.
