oracle - Radion

The oracle channel sends every UMA oracle lifecycle event from the UMAAdapter and UMAOptimisticOracle contracts. We decode each one and send it after the transaction is confirmed on-chain.

{
  "action": "subscribe",
  "id": "s1",
  "channel": "oracle"
}

With no filters, you get every confirmed oracle event from all markets.

Filters

Filter	Type	Required	Description
`market_ids`	`string[]`	No	Condition/market IDs as hex strings. Keeps events for those markets.

This channel accepts only market_ids. wallets, token_ids, and min_usd are ignored here. See Filters for the combination rule.

Events

This channel sends all sixteen UMA resolution events. See Onchain Data for the part each event plays in the full oracle lifecycle.

Payloads

Every frame wraps the event in the standard envelope (type, id, channel, confirmed, data) shown on Frames. Below, each block is the data object for one event — its type discriminator plus every field the ABI decodes. A full frame looks like:

{
  "type": "event",
  "id": "s1",
  "channel": "oracle",
  "confirmed": true,
  "data": {
    "type": "uma_adapter_question_resolved",
    "questionID": "0x…",
    "…": "…"
  }
}

The field is questionID — capital ID, matching the on-chain event signature. uint256 fields serialize as 0x… hex; the signed int256 settledPrice serializes as a decimal string (for example "-1"); bytes fields (ancillaryData, update) serialize as 0x… hex.
