Add an external (and more secure) ETH Address to receive LPT from reward cut.

Add the possibility (via client or flag) of adding an external address to received the LPT earn by the reward call.

I know that certainly need to modify the contract because this address must be added in the blockchain. but if this option could be added at one point, that could be more secure for the orchestrator.

ATM you have to regularly move your LPT from Orch address to another one more secure and less exposed to hack.

In this way, you could keep your LPT bond with a more secure address (by ledger for exemple), and let only a minimal stake on your orch address.

The issue names no files, tests, or concrete entry points. Start by locating the reward call and the client or flag handling it, then trace the related contract interface; done would require a defined external recipient flow and tests covering reward delivery and address security.
