- that sponsorship will be available for any particular Wallet, route, asset, integration, or user,
- that transaction execution will succeed if sponsorship is attempted,
- or that gas sponsorship will reduce costs, improve execution, or provide consistent performance.
2.3.3 Conditions Under Which Sponsorship May Fail

- The Staking Commission may be captured directly at the protocol level or via our validator configuration, reward distribution logic or equivalent mechanics.
