-## Safe Transaction Service

-The Safe Transaction Service tracks transactions related to Safe contracts using tracing on Mainnet, Sepolia, and Gnosis Chain. It uses event indexing for the other chains. For each [supported network](./transaction-service-supported-networks.md) there is one instance of the Transaction Service.

-## Safe Events Service
-
-The Events Service handles Safe indexing events and delivers them as HTTP webhooks, connection to the events queue processed by the Transaction Service. The service's database stores the configuration of webhook destinations.

 ## Architecture
 
-Safe{Wallet} uses these services to offer functionality to end customers via the web and mobile applications. The [Safe Client Gateway](https://github.com/safe-global/safe-client-gateway-nest) acts as a facade between the end customer and the Safe{Core} services and the [Safe Config Service](https://github.com/safe-global/safe-config-service) stores all supported networks and chain-specific variables.

 Safe's production setup consists of several instances of the Transaction Service orchestrated by the Config Service, which are later consumed by the Safe Client Gateway. The Events Service notifies the Safe Client Gateway when new events are indexed, helping to improve the user experience.

 - The Client Gateway leverages the Config Service to find the Transaction Service instance required for a specific request.
 - The Client Gateway forwards the request to the specified Transaction Service instance for the supported networks (determined by the Config Service).
