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 PushOracleReceiverV2 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	Median
Deviation Trigger	0.1%
Heartbeat	24 hours

How to Access On-Chain

1. PushOracleReceiverV2

Contract Addresses

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

Chain	Contract Address
Ethereum	0x5e182977b8753b25C807cb0D2AE6019D3cCCC65E
BNB Chain	0x5612599CF48032d7428399d5Fcb99eDcc75c06A7
Base	0xbdc148d32da286e0542E23f4eD769Ee30a30eDA9
Arbitrum	0x8b247C9d088755A211d73b2C70f87FE9Bf8bf34d

Solidity:

pragma solidity 0.8.29;

interface IPushOracleReceiverV2 {
    function latestAnswer() external view returns (int256);
}

contract OracleConsumer {

    address immutable ORACLE = 0x5e182977b8753b25C807cb0D2AE6019D3cCCC65E;

    function getSatUSDPrice() external view returns (uint128 price) {
        price = IPushOracleReceiverV2(ORACLE).latestAnswer();
        // 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

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
    );
}
