## Case study — Silo Finance The entire data layer owned end to end — subgraphs, multichain APIs across 4+ chains — with infrastructure costs cut 80%. 4+ Chains served by one API · 80% Infrastructure costs cut · 5 Build phases from subgraph to multichain API · 99.9% Uptime SLA target Silo is a permissionless lending protocol where each market is an isolated silo — lenders and borrowers interact within contained risk environments. Running it takes a data layer that keeps up with the protocol: indexers, APIs, and liquidation infrastructure across every chain the protocol reaches. Shipped: - V2 subgraph: The indexing layer the protocol’s apps are built on - Multichain API: One API across 4+ chains, built in 5 phases from subgraph replacement on - Liquidation infrastructure: Monitoring and execution built for market stress - Chain integrations: New chains brought online on launch timelines - GraphQL API + docs: The data layer, documented for integrators Outcome: Silo ships a multichain lending protocol while Bleu keeps the data layer running underneath it — end to end, across every chain, at a fraction of the original cost.
