Gnosis Safe Android App



The Gnosis Safe aims to provide all users with a convenient, yet secure way to manage their funds and interact with decentralized applications on Ethereum. Transactions are secured by on-chain multi-factor-authentication. This is achieved by using the Gnosis Safe smart contracts. They are the successor of the broadly trusted Gnosis Multisig Wallet smart contracts).



The Json RPC depends on Infura. You need to get an API key and create a file named project_keys with the following contents:


Replace <YOUR_PROJECT_ID> with the project id that you get from Infura. You can find this project id at Projects -> Settings -> Keys -> PROJECT ID on the Infura Website.


The Gnosis Safe Android App uses Firebase and your build will fail if you don't have the google-services.json file. To get this file, you need to create a Firebase project at and add at least one Android application. If you didn't change the applicationId in app/build.gradle you need to create an app with the package name to be able to build a debug app. You can find the latest google-services.json file in the Project Settings -> General

After downloading the file, copy it to the app module folder.
