Fake signer (impersonating another account)

To facilitate account impersonation, the Rust SDK provides the FakeSigner. We can use it to simulate ownership of assets held by an account with a given address. This also implies that we can impersonate contract calls from that address. A wallet with a FakeSigner will only succeed in unlocking assets if the network is set up with utxo_validation = false.
