Company · Methodology
One beam of chain data, separated honestly.
PRISM is a market intelligence layer for Robinhood Chain. It shows what the chain says, labels where each figure came from, and leaves blank what it cannot verify.
Methodology
- Direct reads
- Blocks, balances, supplies and reserves are read from the configured RPC at request time with viem. There is no intermediary data vendor.
- Indexed window
- Aggregates such as transfer counts, flows and signals cover a bounded recent block window, stated in every response. Outside it, PRISM makes no claim.
- Verification labels
- Registry assets are listed by the operator in configuration. Discovered tokens were seen emitting Transfer logs and are labeled as such; discovery is not endorsement.
- TVL
- Only computed where one side of a pair is USDG: two times the USDG reserve. Other pairs show reserves without a dollar figure.
- Signals
- Four fixed rules — large transfer, activity spike, flow concentration, liquidity shift — with thresholds disclosed on each card. No model inference.
Configuration
Set these as project environment variables on the deployment. Only the RPC URL is required.
| Variable | Required | Purpose |
|---|---|---|
| ROBINHOOD_RPC_URL | Yes | JSON-RPC endpoint for Robinhood Chain. Without it every data view shows a not-configured state. |
| ROBINHOOD_CHAIN_ID | No | Expected chain ID. A mismatch is flagged on the Network page. |
| ROBINHOOD_EXPLORER_URL | No | Block explorer base URL for outbound links. |
| USDG_CONTRACT_ADDRESS | No | Verified USDG token contract. Enables the USDG page and USDG-denominated TVL. |
| PRISM_ASSET_REGISTRY | No | Comma list of address:category (equity, etf, stablecoin, commodity, other) to label as registry assets. |
| PRISM_CONTACT_EMAIL | No | Address published on the Contact page. |
| PRISM_LOG_WINDOW_BLOCKS | No | Indexed window size, 100–10000. Default 2000. |
| PRISM_LOG_CHUNK_BLOCKS | No | eth_getLogs chunk size, 50–10000. Default 1000. Lower it if your RPC caps ranges. |
| PRISM_DISCOVERY_LIMIT | No | Maximum discovered tokens resolved per request, 0–120. Default 40. |
| UPSTASH_REDIS_REST_URL / _TOKEN | No | Shared cache and cross-instance rate limiting. Falls back to per-instance memory. |
