The format and conventions of this LIP follow the guidelines, so I approve moving this forward as a draft, pending the LIP # assignment.

Summary
Adds a new draft LIP, Delegated Reward Calling, for editor review and number assignment.
What it proposes
Orchestrators must call
reward()once per round from the same wallet that holds their self-bonded LPT and accrued fees, forcing that high-value wallet to stay online and unlocked (a hot wallet) and making multisig orchestrators impractical.This LIP adds a delegated reward caller to
BondingManager: an orchestrator can authorize a separate address to callreward()on its behalf, via a newsetRewardCallersetter and a dedicatedrewardForTranscoderentrypoint. The reward caller is scoped toreward()only — it cannot move funds, change configuration, vote, or redirect rewards, which always accrue to and are checkpointed for the orchestrator. This lets an orchestrator keep its main wallet cold while a low-value key performs the routine call.For editors
LIP number is tentative (
108) pending assignment.
