Oracles

Depredict supports both manual and oracle-based resolution, with first-class support for Switchboard.

Options

Manual Resolution

• When to use: Curated or community-driven outcomes
• How it works: Admin calls resolveMarket with a resolution value
• Cost: Transaction fees only

Switchboard Oracle

• When to use: Data-driven outcomes (prices, feeds)
• How it works: Market stores an oracle pubkey; on resolve the program reads oracle data
• Cost: Oracle job cost (roughly ~$0.15) + tx fees

Creating an Oracle Market

1. Choose OracleType.SWITCHBOARD and pass an oraclePubkey when creating the market.
2. On resolve, the program fetches the value from the oracle account.

import { OracleType, MarketType } from '@endcorp/depredict';
 
await client.trade.createMarket({
  question: 'Will BTC be above $70k at expiry?',
  startTime,
  endTime,
  oracleType: OracleType.SWITCHBOARD,
  oraclePubkey: new PublicKey('...'),
  marketType: MarketType.FUTURE,
  bettingStartTime,
  metadataUri,
  payer,
  feeVaultAccount: feeVault,
});

Resolution requires no manual input:

await client.trade.resolveMarket({ marketId, payer });

Manual Resolution Example

await client.trade.resolveMarket({
  marketId,
  payer,
  resolutionValue: 10, // YES (11 => NO)
});

Tips

• Use manual for subjective outcomes, oracle for objective data
• Store oracle pubkey at creation time to avoid governance risk
• Prefer FUTURE markets if trading should open before the event starts
