Product Description

DigiOracle (formerly KlayOracle) is a highly modular blockchain oracle that allows you securely connect your Web3 applications with events, data, and assets from the real world.

DigiOracle, formerly KlayOracle, won the Public Goods track in the KlayMakers 22 hackathon. Since that time, we’ve rearchitected the protocol to build out the core technology that powers the DigiOracle.

Some of our accomplishments since then:

  • We have rearchitected the DigiOracle protocol to be more decentralized and scalable to support multiple data providers and node operators. See the documented Architecture Decision Record behind this initiative.
  • Launched and tested crypto price feeds on the Klaytn Baobab testnet.
  • Recently launched crypto AND stock price feeds on Klaytn Cypress mainnet (see Features section below).
  • Launched multiple bootstrap data providers, nodes and 21 data feeds on Klaytn mainnet.
  • DigiOracle’s data explorer dashboard (launching August 2023).
  • Updated website and rebranded to DigiOracle, to expand and support more chains (ongoing) after the completion of other features and launch of our token on Klaytn.

Components of DigiOracle

Data Providers

Data providers are responsible for subscribing to data sources and configuring data feeds and Oracle contracts accessible to end users.


Nodes on DigiOracle are responsible for handling computational tasks on behalf of data providers, including data retrieval, filtering, and aggregation.

Data Sources

Verifiable entities that provide real-world data through APIs, hardware, and other channels. DigiOracle uses various methods to ensure data integrity from these sources.

    uint256 public klayOutput;

    constructor(address _oracleAddress) {
        require(_oracleAddress != address(0));
        oracleAddress = _oracleAddress;

    function swapUsdtoKlay() public returns (bool) {
        KlayOracleInterface oracle = KlayOracleInterface(oracleAddress);

        bool replied = oracle.newOracleRequest(

        return replied;

    function swap(uint256 _klayOutput) external {
        require(msg.sender == oracleAddress, "not allowed"); //ensure only Oracle contract can set price
        klayOutput = _klayOutput;
        //Swap usd to klay

Grant Proposal

We are seeking a $41,300 grant to aid in the future growth and development of DigiOracle

We’ve built the core technology that enables DigiOracle to integrate multiple data feeds and node operators and provide real-world events and assets on-chain. Besides crypto price feeds, we have also launched stock price feeds on the Klaytn mainnet, marking our foray into bringing real-world assets on-chain.

Besides the $30,000 prize money from the hackathon and a $25,000 grant from DoraHacks, the DigiOracle core team has built DigiOracle from the ground up without further external funding.

As we have achieved a significant milestone in our roadmap with the launch on mainnet, we require additional funding to reach the next level in our product evolution: increased adoption and integration of real-world assets.

Milestone 1:

  • Test and launch VRF functionality on Klaytn mainnet,
  • deploy projects on Klaytn to utilize DigiOracle’s oracles (1 NFT project, 1 DeFi, and 1 lottery project, and 1 other community projects),
  • publish at least 10 Klaytn-focused educational resources and onboard Klaytn developers to DigiOracle’s Champion Program,
  • complete documentation and launch whitepaper
  • We also intend on fully supporting Klaymakers 23 hackathon participants with dedicated nodes and custom requested data feeds and developer support during the hackathon.
  • DigiOracle SDK for Javascript & Go. For developer to access Data Feeds outside Smart Contract

Cost: $20,650
Timeframe: 3 months.

Milestone 2:

  • Launch $DIGI token with $KLAY burn mechanism,
  • implement payment, rewards and slashing mechanisms for node operators and data providers
  • onboard 3 - 5 more external dApps to use DigiOracle on Klaytn,
  • integrate more data and real-world asset feeds, including real-estate and proof-of-reserve data feeds.

Cost: $20,650
Timeframe: 3 months

A breakdown of our intended sub-goals to achieve these milestones is covered in the following sheet: DigiOracle (KlayOracle) Budget - Google Sheets

Benefits to the Klaytn ecosystem

DigiOracle’s integration into the Klaytn ecosystem offers several clear and impactful benefits. Here are a few of them:

Integration of Real-World Assets

Our expansion into supporting real-world assets, such as stock price feeds, directly aligns with Klaytn’s vision of bridging the gap between blockchain and traditional finance. This integration allows Klaytn dApps to offer innovative financial instruments and products that combine both crypto and traditional asset classes. As a result, users can access a broader range of investment opportunities, further attracting traditional investors to the Klaytn ecosystem. We will

Developer Adoption and Onboarding

Our commitment to creating educational resources and hiring a Developer Relations engineer will greatly benefit the Klaytn ecosystem. By providing comprehensive guides, tutorials, and sample projects, we’ll empower developers to easily integrate its oracle services into their Klaytn-based applications. This lowered entry barrier accelerates the adoption of DigiOracle and contributes to the growth of the Klaytn developer community.

Currently, Paul Oladimeji, DigiOracle’s co-founder is a Klaytn ambassador, creating educational resources and organizing community initiatives aimed at onboarding more participants into the Klaytn ecosystem.

Tokenomics and Sustainability

While we are no cryptonomic experts, our planned token launch and burning mechanism demonstrate a commitment to sustainable tokenomics. By generating tokens through burning KLAY fees, we plan to ensure a reduction in the overall supply of tokens over time, which can lead to increased scarcity and potential value appreciation. This approach aligns with Klaytn’s interest in promoting responsible tokenomics within its ecosystem.

Network Security and Reliability

The implementation of payment, rewards, and slashing mechanisms for data providers and node operators enhances the security and reliability of DigiOracle’s services. This directly benefits the Klaytn ecosystem by ensuring the availability and accuracy of external data, a critical component for the proper functioning of various dApps, especially those with financial and high-stakes use cases.

Apart from these, as Klaytn has been our launch chain and biggest supporter, most of our future features will be piloted on Klaytn before being onboarded to any other chain.

Thank you to the Klaytn community for the overwhelming support so far, and we look forward to your questions and comments.


How will the Klaytn community get benefit from the $DIGI token launch at milestone 2?
And there is an Orakl Network (https://www.orakl.network) that supports Klaytn. Is there anything different about it?

Hi @Creder-Itcen,

Thank you for your question. I’ll try to answer them below.

Firstly, we strongly believe that the Klaytn ecosystem will benefit greatly from diversity, where developers have several options of high-quality oracles to choose from.

Secondly, as mentioned in our pitch, while DigiOracle has launched with “conventional” crypto price feeds and HTTP APIs, our key focus is the integration of real-world assets on-chain, including tangible assets such as real estate and collectibles, as well as intangible assets such as stocks. This is different from Orakl’s mission as far as we know.

The RWA market is a multi-billion dollar market with a multitude of use cases and applications. Having one (or more) oracle(s) on Klaytn focused on this market would bring a lot of value to the ecosystem.

To answer your question about the benefit of the $DIGI token launch to the Klaytn community:

The $DIGI token will incorporate a burn mechanism that aims to reduce the circulating supply of $KLAY.

  • Each data provider will maintain a $KLAY treasury, from which the $DIGI token will be minted to pay node operators.
  • The $DIGI token will be fully launched on Klaytn, and in a multi-chain architecture, DigiOracle data providers running on other chains would have to bridge their tokens to $KLAY.
  • During the $DIGI token generation event, we plan only to mint a portion of the total supply of $DIGI token. The rest of the supply will be minted each time by burning an equivalent portion of $KLAY in the data provider’s treasury.
  • The newly minted $DIGI token is then paid to node operators as fees by the data provider.

The burning of $KLAY during this procedure reduces the $KLAY token circulating supply, thus increasing its value.

Looking forward to your additional comments!


KF decided not to endorse this proposal for the following reason:

  • Considering KF is running Orakl, it would be an overinvestment to provide a grant to another oracle product. In particular, we could not find the difference between DigiOracle and Orakl. Orakl is also trying to provide service related to real world assets.
