Indexing & Backfilling sends Radion’s decoded Polymarket events into your own systems. You get the same data that powers Radion — markets, trades, positions, and resolutions — written straight into your database or pushed to your topics. You do not have to run an indexer yourself.
How the pipeline works
Radion reads Polygon logs through an optimized ingestion approach that goes beyond traditional JSON-RPC, making us faster than our competitors. It decodes them and pushes them through Redpanda into a Postgres read-model. The same decoded stream is what we deliver to you.
What you get
Decoded, typed events from across Polymarket:
| Group | Includes |
|---|
| Trades | Order fills, matches, and fees across exchange versions |
| Positions | Conditional-token splits, merges, redemptions, and conversions |
| Holders | ERC-1155 transfers, turned into balances per holder and position |
| Resolutions | Condition resolutions, neg-risk outcomes, and the UMA oracle flow |
Backfill and live sync
- Backfill loads a past block range into your destination in one pass. If a backfill stops, it picks up where it left off instead of starting over.
- Live sync takes over once the backfill reaches the tip. It keeps your destination up to date as new blocks land.
What we promise
- Reorg-safe. When the chain rewrites a block, we fix the affected rows for you. Your data lands on the canonical chain.
- No duplicates. Every row is keyed by its on-chain spot —
(chain_id, block_number, log_index). Sending a row again just overwrites it, so backfill and live sync can overlap with no doubles.
- In order. Events arrive in block and log order per stream.
Scope
Pick what you receive, so you only store what you need:
| Option | What it does |
|---|
| Contracts | Keep only certain Polymarket contract addresses |
| Event topics | Keep only the event types you choose |
| Block range | Set the start and end of the backfill |
Destinations
| Destination | What happens |
|---|
| Postgres | Radion makes the schema and writes rows, with upsert and dedup |
| Redpanda | Radion pushes decoded events to your topics, in order |
