Mainframe

Hifi Protocol Subgraph

The Graph subgraph that indexes the Hifi fixed-rate, fixed-term lending protocol — vaults, collateral and debt positions, listed bonds and collaterals, AMM pools and swaps — and serves them over GraphQL. This is the only machine-readable contract Mainframe publishes; the schema is captured verbatim in graphql/. WARNING: the endpoint Hifi's own documentation names is on The Graph's retired hosted service and returned HTTP 404 when probed 2026-08-13, and the docs name no replacement, so the surface is documented but not currently callable.
