DripStream supports set_operator/revoke_operator so a sender can delegate day-to-day operations to another address. DripGovernor and TwapOracle both have full Role-based RBAC. TokenVault (contracts/token-vault/src/lib.rs) has a single owner: Address with no delegation mechanism at all — every privileged call (withdraw, set_limit) requires the exact owner key to sign, with no way to hand off day-to-day withdrawal authority to a hot wallet or ops key the way the other three contracts allow.
