Cons	Hosted Defender SaaS shuts down permanently on July 1, 2026 Self-hosting Relayer and Monitor creates internal devops maintenance overhead Custom security audit and Continuous Security advisory fees require institutional quotes	Data settlement is delayed by the required challenge window duration Resolution finality depends on tokenholder voting participation and governance distribution Staking voter yields rely on protocol token emissions rather than fixed fiat revenues
Best for	Smart contract developers deploying standard tokens, Institutions building regulated stablecoins and funds, Teams needing automated, self-hosted transaction relaying	Prediction market settlement, Cross-chain bridge relayers, DeFi protocols requiring arbitrary data
