# Coverage Methodology

> Per-protocol matrix of which lending-sector event abstractions Allium supports, documents, or still needs to cover.

The `<chain>.lending.coverage_methodology` table is a coverage matrix for the lending vertical. Each row is a project/protocol on a chain, with the sector abstractions Allium models, which of those are implemented and documented, and which are still missing.

Use it to see whether a lending protocol has full event coverage (`deposits`, `withdrawals`, `borrows`, `repayments`, `liquidations`, and related abstractions) before relying on the event tables.
