Contract Overview

The DelphAI contract provides an AI-powered resolution oracle for prediction markets. Platforms can create markets on DelphAI by paying a creation fee, and the AI resolver will automatically resolve them at the scheduled time. Contract Address: 0xA95E99848a318e37F128aB841b0CF693c1f0b4D1 (BSC Mainnet)

​
Market Functions

​
createMarket

Create a new prediction market with AI resolution. 
function createMarket(
    string memory question,
    string memory description,
    string[] memory possibleOutcomes,
    uint256 resolutionTimestamp
) external payable returns (uint256 marketId);
Parameters:
  • question - The market question
  • description - Additional context and resolution criteria
  • possibleOutcomes - Array of possible outcome strings (minimum 2)
  • resolutionTimestamp - Unix timestamp when AI should resolve the market
Returns:
  • marketId - Unique identifier for the created market
Requirements:
  • msg.value must be greater than or equal to marketCreationFee
  • question must not be empty
  • possibleOutcomes must have at least 2 options
  • resolutionTimestamp must be in the future
Example: 
uint256 fee = delphAI.marketCreationFee();

string[] memory outcomes = new string[](2);
outcomes[0] = "Yes";
outcomes[1] = "No";

uint256 marketId = delphAI.createMarket{value: fee}(
    "Will BTC reach 100k by December 31, 2025?",
    "Market resolves YES if Bitcoin is above 100k USD",
    outcomes,
    1735689599
);
Emits: MarketCreated event

​
resolveMarket

    uint8 resolutionConfidence,
    bytes memory proofData
) external;
Parameters:
  • marketId - The market to resolve
  • outcomeIndex - Index of the winning outcome in possibleOutcomes array
  • resolutionData - AI explanation and reasoning for the resolution
  • resolutionSources - Array of source URLs used for resolution
  • resolutionConfidence - Confidence level of the resolution (0-100)
  • proofData - TEE attestation or cryptographic proof (future feature)
Requirements:
  • Only callable by authorized resolver address
  • Market must exist and be in Open status
  • Current time must be greater than or equal to resolutionTimestamp
  • outcomeIndex must be valid
  • resolutionConfidence must be between 0 and 100
Emits: MarketResolved event

​
cancelMarket

function cancelMarket(uint256 marketId) external;
Parameters:
  • marketId - The market to cancel
Requirements:
  • Caller must be market creator or contract owner
  • Market must be in Open status
Emits: MarketCancelled event
