-* `--source-account <SOURCE_ACCOUNT>` — Account that where transaction originates from. Alias `source`. Can be an identity (--source alice), a public key (--source GDKW...), a muxed account (--source MDA…), a secret key (--source SC36…), or a seed phrase (--source "kite urban…"). If `--build-only` or `--sim-only` flags were NOT provided, this key will also be used to sign the final transaction. In that case, trying to sign with public key will fail
