Oracle Core ETH Connector Fork is a community fork of the oracle core software, adding an Ethereum connector for operators who run oracles in Ergo oracle pools. It suits technically experienced people who already know how oracle pools, full nodes and wallets fit together, rather than newcomers looking for a simple app. The fork is free and open source, and its source code is hosted on GitHub.
Read this before installing: the most recent code update is dated October 25, 2023. That makes the project more than two years old, so it should be treated as a dated build rather than actively maintained software. The latest listed version is v2.0.0-beta12, a beta release. The sections below cover what the core does, how to set it up and how to judge the risks.
What Is an Oracle Core in an Oracle Pool?
An oracle pool is a group of data providers that publish outside values onto a blockchain, so smart contracts can read them. Each participant runs software that gathers the value, signs it and submits it on a schedule. The oracle core is the layer that does this work on the operator's side. It coordinates node access, wallet activity and communication with the pool, so the operator is not handling each step by hand.
Because the core works closely with a wallet and a node, it sits in a sensitive spot. It reads chain state, builds transactions and exposes a local API port for status queries. Think of it as the operator's agent on the network rather than a stand-alone desktop app. That is why the setup demands a dedicated full node, and why a configuration mistake can affect real funds instead of only a dashboard. Operators usually monitor the core through its local interface and check it after every restart to confirm the pool sees their submissions.
Who Should Consider an Ethereum Connector Variant?
This fork makes most sense for technically comfortable operators who already understand oracle pools and want an Ethereum connector inside the same toolchain. A typical case is an operator who runs several oracle instances, each isolated with its own API port, while sharing one full node across all of them. The fork gives that operator one codebase to maintain instead of patching the upstream software by hand.
It is a poor fit for people new to blockchain infrastructure. Setting parameters, syncing a node and reading logs all require hands-on familiarity. Developers who simply want to write or test smart contracts will find tools such as Foundry more relevant. Operators who need an actively maintained release with recent updates should look elsewhere, since this fork has not seen a code update since late 2023. Start in a test environment before moving any real pool work onto it.
Key Terms: Full Node, UTXO Set and API Port
A full node stores a complete copy of the blockchain and checks every block and transaction against the network's rules. Running one gives the operator independent verification instead of trusting a remote server. The core relies on this because it needs direct access to chain data and a wallet.
The UTXO set is the collection of unspent transaction outputs, meaning the amounts that can still be spent on the chain. Scanning it lets software find which funds belong to a given wallet and which are available for new transactions. Scanning can take a while on a large chain, so expect the first run to be slower than later ones.
An API port is a numbered network endpoint on your computer where a program answers local requests. Each oracle core instance needs its own port. If two instances try to use the same one, the conflict usually stops the second from starting, which is a simple sign that the configuration needs adjusting.
Key features
Ethereum connector
One oracle per core
Wallet-linked transactions
Supported coins
Documentation for this software names Ergo (ERG) as the network its oracle pools run on. The Ethereum connector is the addition this fork brings, so anyone planning Ethereum-side work should review the repository code and test it in a non-critical setup before relying on it.
How to install Oracle Core ETH Connector Fork on Windows
- 1
Get the build from GitHub
Open the GitHub Releases page for the upstream project at github.com/ergoplatform/oracle-core/releases, or the fork's source repository at github.com/Luivatra/oracle-core. Download only from the official website or the project's GitHub Releases page. The fork's latest listed version is v2.0.0-beta12. Windows builds are described as likely, so look through the release assets for a Windows file before you start. Docker is also listed as a platform, which can be an alternative if a container image is offered.
- 2
Verify the file
Compare the SHA-256 checksum of the download with the value published on the release page, or check the release signature if one is provided. If nothing is published to compare against, do not run the file. Keep a copy of the checksum with your setup notes so you can repeat the check after future downloads.
- 3
Install to a dedicated folder
Extract or install the build into its own folder, separate from wallet files and other tools. Keep the configuration file in the same place so you can track parameter changes over time. A clean folder structure also makes it easier to back up and roll back a version.
-
Set the required parameters
Fill in the required parameters in the configuration. Reward token parameters are only needed if you are minting a new reward token. Before using any contracts, the documentation recommends checking that they come from EIP-23, using the encoded hashes the software outputs for each contract.
System requirements
- A full node wallet, which the core needs to create transactions and scan the UTXO set
- A separate core instance and API port for each oracle pool you operate
How to use Oracle Core ETH Connector Fork
Once the core is installed and configured, day-to-day use is mostly about monitoring and keeping the node in sync. The steps below describe a typical flow for one oracle instance.
- Start your full node and let it finish syncing before launching the core.
- Unlock the wallet only when the core needs to sign, and keep your seed phrase offline.
- Set the API port for this instance so it does not clash with other cores on the machine.
- Launch the core and check its local API for a status response.
- Repeat the setup with a different port and configuration for each additional oracle.
- Review the logs after each restart and confirm the node's sync state.
Keep a written record of each instance's settings, including its port and pool. That record makes recovery much faster if a restart or update goes wrong.
Pros & cons
- Adds an Ethereum connector that the upstream core does not include
- Open source and free to use
- Supports running several oracles on one shared full node
- One core per pool keeps each oracle's configuration isolated
- Last code update is dated October 25, 2023, more than two years ago
- Labeled as a beta, with the latest listed version being v2.0.0-beta12
- Requires a full node wallet and hands-on setup
- Windows build availability is described as likely, not confirmed
Is Oracle Core ETH Connector Fork safe?
This software works with a wallet and signs transactions, so treat it with the same caution as any tool that touches funds. Download only from the official website or the project's GitHub Releases page, and avoid copies offered on forums or file-sharing sites. Check the SHA-256 checksum or signature against what the publisher lists before running anything. Never type your seed phrase into a website, a chat or a tool that asks for it unexpectedly. The last code update is dated October 25, 2023, so the project is more than two years old. Dependencies and node software may have changed since then, so check the latest version on the official website and review the code before trusting it with real funds.
- Official source only. Download from github.com/Luivatra/oracle-core. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Foundry is a toolkit for building, testing and deploying EVM smart contracts, so it helps developers write code, while this core runs as an operator service for oracle pools. Alchemy, Infura and QuickNode provide hosted RPC access, which removes the need to run your own node. This software does the opposite and expects a local full node wallet. Postman is useful for sending manual JSON-RPC requests to a node while you troubleshoot a connection. Anchor, by contrast, targets Solana programs, so it serves a different chain entirely. Choose by role: operator tooling, developer tooling, or a hosted endpoint.

Frequently asked questions
Yes, the fork is free and open source, and its source code is available on GitHub. Free access does not cover the cost of running a full node or the time needed for setup and monitoring. Read the repository's license file before redistributing or modifying the code, since the license terms determine what you may do with it.
It can be used safely only with careful verification, since it works alongside a wallet and signs transactions. Treat the download and configuration with care, and review the code before trusting it with funds. The last code update is dated October 25, 2023, so testing in a non-critical setup first is a sensible step. The safety section lists the full checklist.
The project indicates that builds for Windows exist, but support is listed as likely rather than confirmed. Look through the release assets for a Windows file before planning your setup. If none is offered, Docker is also listed as a platform, which may be an alternative route.
The documentation names Ergo (ERG) as the network for its oracle pools. The Ethereum connector is the addition this fork makes, so Ethereum-side functionality is its main difference from the upstream software. Check the repository before planning any work beyond Ergo.
Yes. A single full node can serve several oracles, but each oracle needs its own core instance. Each instance also needs a separate API port so the setups do not conflict with each other on the same computer.
The last code update is dated October 25, 2023, which is more than two years ago, so the project should not be treated as actively maintained. Use it as a reference build, and compare it with the latest releases on GitHub before deciding whether it fits your needs.
Verdict
Oracle Core ETH Connector Fork fits experienced operators who want an Ethereum connector variant of the oracle core and are comfortable running a full node. Its beta label and the October 2023 last update mean it works better as a reference or a starting point than as production software. Review the source, verify the download, and test in a non-critical environment before connecting it to real pool work. Choose a maintained alternative if you need a current release.
