Protocol-facing (B2B)
Feeds other protocols can consume directly.
Utilities
| Utility | Data source | Third-party | Self-hosted |
|---|---|---|---|
| Collateral Haircut Feed — lending protocols widen haircuts while the exchange is closed | RiskFeed on-chain | Gas (ops cost) | Publisher worker |
| Corporate Action Feed (JSON/ICS) | Corporate Action Extractor | — | Static file serving from the main binary |
| Halt Mirror — mirror NYSE/Nasdaq halts as an on-chain feed | Exchange halt notices | Nasdaq Trader + NYSE halt feed (free) | Poller worker |
| LP Toxicity Dashboard — which pools get picked off by informed flow overnight | Swap indexer + oracle mid | — | Heaviest load — needs per-swap attribution |
One of these is not like the others
LP Toxicity Dashboard is the expensive one
Per-swap attribution against the oracle mid at execution time pushes storage and CPU well beyond what the core risk engine needs. Build it once an LP actually asks for it, not before.
