  • You’ll go through a process to understand the way to integrate Stork price feeds after creating task on Gelato app.
Please create oracle tasks using the UI available in the oracle section of the Gelato App. Manual creation via web3-functions is discouraged to ensure proper configuration and operation.

​
Initial Steps

1

Create an Oracle Task in the Gelato App

As outlined in the Quick Start guide, begin by creating a new Oracle Task in the Gelato App. Select Stork as your data provider and choose the specific price feeds you wish to monitor. This setup ensures your application receives real-time data from the selected pairs.
2

Fund Your Dedicated msg.sender Address

It is necessary to deposit some ETH to your dedicated msg.sender because Stork enforces a fee for each price update. This fee is calculated dynamically based on the number of updates you submit, though in most cases, it amounts to just 1 WEI per update. To prevent transaction reversion, ensure that your dedicated msg.sender address is sufficiently funded to cover these fees.Stork Funding
3

Integrate the Price Feeds into Your Smart Contract

Once your Oracle Task is live, you can pull the associated price feeds into your smart contract. For a list of Stork contract addresses and integration details, refer to the Supported Networks. Incorporate these feeds into your contract’s logic as needed to automate on-chain functions with reliable, accurate market data.

Example Code

// YourContract.sol
contract YourContract {
    IStork public stork;
    // ...
    constructor (address _stork /*, ...*/) {
        stork = IStork(_stork);
        // ...
    }
    //...
}

interface IStork {
    function getTemporalNumericValueUnsafeV1(
        bytes32 id
    ) external view returns (StorkStructs.TemporalNumericValue memory value);
}

contract StorkStructs {
    struct TemporalNumericValue {
        // slot 1
        // nanosecond level precision timestamp of latest publisher update in batch
        uint64 timestampNs; // 8 bytes
        // should be able to hold all necessary numbers (up to 6277101735386680763835789423207666416102355444464034512895)
        int192 quantizedValue; // 8 bytes
    }
}
