The dex subgraph indexer only consumed EVM 0x9999 settlement logs (the
cross-chain settlement view). On a native-DEX deployment the trade engine
IS the D-Chain (dexvm): a trade is a consensus state transition matched at
Block.Verify, not an EVM event, so native fills never appear on the EVM RPC
and the dex subgraph stays empty (markets:null).
Add CLOBSource (indexer/clob.go): an orthogonal, READ-ONLY poller of the
D-Chain committed-state read RPC clob_get_{markets,trades,orders} that writes
the same Market/Fill/Order entities the existing dex resolvers serve. Enabled
by Config.DexRPC; empty preserves EVM-only behaviour. The two sources share
only the store and the entity shapes, so this is purely additive — the amm
(EVM) subgraph is untouched.
- markets <- clob_get_markets (per-market authoritative book summary; bound-
market hex symbol decoded to its human pair, e.g. LUX/LUSD)
- fills <- clob_get_trades?since=<h> (global height-ordered log; keyed
height:seq -> idempotent; incremental by accepted height)
- orders <- clob_get_orders?market=<id> (resting book per market)
Tests (httptest doubles serving the exact read.go JSON shapes captured live
from lux-devnet): markets/trades/orders ingest + symbol decode, incremental
cursor + idempotent re-read, and EVM-AMM no-regression with DexRPC set.
