Class: MemoryStore

Defined in: packages/overcast-core/src/storage/memory.ts:57

In-memory reference implementation of the storage ports. Backs both the trusted write side (OvercastStore) and the public read side (OvercastView); a real deployment swaps this for a database-backed store implementing the same interfaces.

Reads return curated (display) shapes, so the store is constructed with an AssetRegistry used to resolve asset addresses to metadata on the way out. Filtering, sorting and pagination are done in JS here — the same query objects a SQL implementation would push down to the database.

insertEvents()

insertEvents(events): Promise<void>;

Defined in: packages/overcast-core/src/storage/memory.ts:90

Insert a batch of indexed on-chain events, updating the derived offer / option / totals projections. Idempotent per event so re-indexing a range is safe.

listAssets()

listAssets(): Promise<object[]>;

Defined in: packages/overcast-core/src/storage/memory.ts:303

The backend's asset allowlist (GET /assets) — the curated metadata that raw OptionDetails asset addresses are resolved against. Drives a client's pick-from-list UX and symbol display; the backend rejects any RFQ / quote / offer over an asset absent from this list. Returned as a bare list (not paged) — it is a small, fixed allowlist, not indexed data.

Returns

Promise<object[]>

Implementation of

OvercastStorage.listAssets

---
