DIA Oracle

DIA is a decentralized oracle platform supporting thousands of assets across 50+ blockchains. For satUSD, DIA delivers high-frequency, deviation-based price updates using their battle-tested DIAOracleV2 and AggregatorV3Interface-compatible adapters, ensuring compatibility with most DeFi protocols and aggregators.

Oracle Configuration

The satUSD price feed uses the following configuration across all chains:

Parameter	Value
Pricing Method	MAIR (Moving Average with Interquartile Range)
Deviation Trigger	0.5%
Refresh Frequency	120 seconds
Heartbeat	24 hours

How to Access On-Chain

1. DIAOracleV2

Contract Addresses

These are the main contracts to call for direct access to price data.

Chain	Contract Address
Ethereum	0xACa485Dd4299090251422617f5938d324C85191B
BNB Chain	0xbea082c15417716541D3169e7a48e4A53A19B5D1
Base	0x12B0B8bCd48ee30905DB5B0e181368Dda90eaF0B

BOB	0xD8ba4Bf8d2b8Aa639fD0affd6fDF180D503ed458

Solidity: Using getValue from DIAOracleV2

pragma solidity 0.8.29;

interface IDIAOracleV2 {
    function getValue(string memory key) external view returns (uint128, uint128);
}

contract OracleConsumer {

    address immutable ORACLE = 0xbea082c15417716541D3169e7a48e4A53A19B5D1; // BNB Chain

    function getSatUSDPrice() external view returns (uint128 price, uint128 timestamp) {
        (price, timestamp) = IDIAOracleV2(ORACLE).getValue("satUSD/USD");
        // Note: `price` has 8 decimals (e.g., 99882732 = $0.99882732)
    }
}

2. Adapter Contracts (Chainlink-Compatible)

For protocols expecting a Chainlink-style interface via AggregatorV3Interface.

Contract Addresses

Chain	Contract Address
Ethereum	0x02eaBD9c59fCa5B38E5A415e6172F93BF30fB2af
BNB Chain	0x1082679a55fB34B967a006080204b597CfA0605C
Base	0x4aE9A0a4c02Ec4ffb7F231717DF85D755192884A
Arbitrum	0x6f076AddEf5e393F23988B0f61b02d0297022fa4
BOB	0x230057c84fACFC5358C500E5348E16D4D7Dc60f8

Solidity: Use DIA’s adapter contracts via the AggregatorV3Interface interface:

interface AggregatorV3Interface {
    function latestRoundData() external view returns (
        uint80 roundID,
        int256 answer,
        uint256 startedAt,
        uint256 updatedAt,
        uint80 answeredInRound
    );
}
