KlayOracle is an open-source oracle framework to securely integrate off-chain data with Klaytn smart contracts.
We are requesting for a $45,000 USD grant from the Dora GrantDAO to further assist with the early-stage development and deployment of KlayOracle. Please refer below for the project overview, milestones, team background, goals, and other information for your consideration.
Klaytn is an open-source public blockchain for building dapps for the metaverse. Due to its rapidly growing popularity, developers working on the Klaytn blockchain need access to multiple sources of publicly available and reliable data to use in their dapps.
KlayOracle is modeled after leading and existing oracles on the Ethereum and Solana blockchains such as ChainLink, Band Protocol, and Gravity. With KlayOracle, smart contract developers can access reliable and transparent data such as price data, sport data, weather data, random numbers or other external APIs, and easily integrate them within their Klaytn dapps.

We have already built a functional proof-of-concept of KlayOracle, with open-source code available on GitHub.
Some of the data sources currently supported by KlayOracle include:
For example, the snippet below shows a sample job definition for getting random numbers from multiple feeds to be returned and used by an NFT smart contract or game contract for a dice-roll usecase. Developers can also define more sophisticated job specifications depending on their use cases.
Above is a job specification for an Oracle to get KLAY/USD price to be returned to a smart contract through an Oracle. The job defines data feeds that specify URLs to get the data and reducers such as PARSE, MUL to manipulate the data returned.
KlayOracle is bundled with the kloc command, which is used to interact with the KlayOracle node. It currently supports the following commands:
- Create Klaytn wallet for a node, so that it can fulfill oracle requests.
- Get node information
- Run the Node to start watching for jobs and fufilling Oracle requests from smart contracts.
KlayOracle Node is very minimal in size and can watch and process hundreds of jobs easily (from current tests). This makes it easy to host your own node if you decide not to use publicly hosted ones. However, KlayOracle comes with a publicly hosted node which is currently free to access.
A KlayOracle adapter defines the job specification for getting specific offchain data for an Oracle request. An adapter is made up of different parts, which are:
- Job Type (Data Feed / Random Number)
- Adapter ID (Unique 32-length string)
- Oracle Address
- Feeds (Which defines rules to manipulate offchain data to be returned to the Oracle contract)
Developers can easily create adapters of thier own to get price feeds, random numbers, or beyond that, make http requests for custom data intended to be passed to the smart contract e.g Weather Report data.

So far, we have been able to accomplish the following milestones in the development of KlayOracle:
- KlayOracle v0.0.5 Adapter
- KlayOracle v0.0.5 Oracle Contract
- KlayOracle v0.0.5 Node
- KlayOracle Baobab Deploy
- Website and Landing Page
- KlayOracle v0.0.5 documentation
- Video Tutorials
As you can see, we have made significant progress with the development of KlayOracle v0.0.5. However, there are still major development and documentation activities needed to ensure a more functional and standardized v0.0.5, and for this, we are raising $10,000. We estimate this milestone to be completed by Q4 2022. These funds will be deployed toward the following activities:
- Complete KlayOracle v0.0.5 Node, and onboard test node runners and validators.
- Deploy publicly-hosted KlayOracle node.
- Add Weather data sources to adapter list.
- Improve documentation & video tutorials, targeted at open-source contributors, node runners, validators and end-users (smart contract developers).
Our second milestone is focused on getting KlayOracle ready for deployment on mainnet and public use. We also aim to make it more censorship-resistant and decentralized by implementing token-based reward systems for participants in the network. We expect this milestone to be completed by the end of Q1 2023. To achieve this target, we will deploy the funds to do the following:
- Conduct a Smart contract and code audit – $10,000
- Build and release KlayOracle Node V1.0 for testnet – $8,000
- Build a token reward system for Node runner – $5,000
- Build a token reward system for Node validators – $3,000
- Get beta testers to build dapps on Klaytn testnet using KlayOracle – $2,000
- Technical Writing & Content – improved documentation, tutorials (text and video) – $3,000.
- Content Marketing & Technical Writing – developer support, community management, sponsored posts – $4,000.
- Launch KlayOracle on Klaytn mainnet.
We hope for a positive response and continued support from the amazing GrantDAO and DoraHacks community.
