Indexing & Backfilling is on the Enterprise plan, on demand. Radion sets
up the pipeline for you from the scope you choose below.
What you get
Decoded, typed events across Polymarket — trades, positions, holders, and resolutions. The full event list is in Onchain Data.1. Choose the scope
Pick what you receive, so you store only 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 |
2. Pick a destination
| 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 |
3. How the backfill runs
- Backfill loads the past block range in one pass. If it stops, it resumes where it left off instead of starting over.
- Live sync takes over once the backfill reaches the tip and keeps your data current as new blocks land.
What Radion promises
- Reorg-safe. When the chain rewrites a block, Radion fixes the affected rows so your data lands on the canonical chain.
- No duplicates. Every row is keyed by
(chain_id, block_number, log_index). Re-sending a row overwrites it. - In order. Events arrive in block and log order per stream.
