Dapp interaction

The web3 provider injected by the Gnosis Safe Authenticator has been separated in a different github repository (SafeWeb3Provider) and is imported and injected by this extension.

Dapps must be whitelisted in order to have full access to the provider.

It is highly recommended to integrate it in your Dapp to asure a good performance.

Different situations:

• Only the Gnosis Safe Authenticator is installed

  • Dapp is not whitelisted
    • Dapp integrates safe-web3-provider
      • Dapp is unusable. Local safe-web3-provider is empty (no Safe account data and pop-up never opens).
    • Dapp is not integrated with the Safe
      • Dapp is unusable.
  • Dapp is whitelisted
    • Dapp integrates safe-web3-provider
      • safe-web3-provider is injected by default. Local safe-web3-provider can be used if selected.
    • Dapp is not integrated with the Safe
      • safe-web3-provider is injected by default. Be careful if Dapp listens to the provider at load event. There is no problem with Dapps that load the provider using a button.

• Both Gnosis Safe Authenticator and Metamask are installed

  • Dapp is not whitelisted
    • Metamask is used
  • Dapp is whitelisted
    • Dapp integrates safe-web3-provider
      • Local safe-web3-provider is used.
    • Dapp is not integrated with the Safe
      • Metamask is used.
