Safe

Safe{Wallet} (smart-contract multisig) integration for hub. EVM only; runs as a Safe App inside the Safe iframe and submits transactions through the Safe transaction service.

Account switching

changeAccountSubscriber is wired up on the namespace but is not exercised in practice. When the user switches the active account in Safe{Wallet}, Safe reloads the Safe App iframe, so the whole dApp (and our provider state) is reinitialized from scratch rather than reacting to an in-place account-change event. There is therefore no live session in which the change-account subscriber would fire — the new account is picked up on the fresh load via eth_accounts. It is kept for interface parity with other EVM namespaces.

Switch network

The same reload behavior applies to network switching. A Safe App is bound to the chain of the Safe it is embedded in, and changing the active network in Safe{Wallet} reloads the Safe App iframe — reinitializing the whole dApp (and our provider state) from scratch rather than emitting an in-place chain-change event. There is therefore no live session in which an in-place network switch could be observed; the new chain is picked up on the fresh load via eth_chainId.
