The Arbitrum Foundation’s support for EDU Chain was a real grant and ecosystem partnership—not an announcement that Arbitrum owns or operates the network. Open Campus announced the funding on July 3, 2024, to support an education-focused Layer 3 blockchain built with the Arbitrum Orbit Stack. EDU Chain’s official developer documentation now lists a mainnet configuration settling on Arbitrum, but that fact alone does not establish broad adoption or institutional use.
What the Arbitrum Foundation supported
Open Campus announced on July 3, 2024, that it had received designated grant funding from the Arbitrum Foundation to support EDU Chain’s launch. The announcement described a combination of financial and ecosystem support: educational-content initiatives connected to the Arbitrum Ambassador Program, participation in Arbitrum hackathons, and incentives for developers building applications for EDU Chain. The grant amount was not disclosed in that announcement. Open Campus’s announcement also cited 96 active Arbitrum ambassadors and 26 affiliated universities for its planned content work; those are historical figures from 2024, not current totals.
The distinction matters: the Foundation backed a project and helped connect it to an ecosystem. The announcement does not say that the Foundation created EDU Chain, runs it, or guarantees its success.
Who is behind EDU Chain?
| Organization | Role described in the available materials |
|---|---|
| Open Campus | Education protocol and ecosystem associated with EDU Chain; announced that it received the Foundation grant. |
| EDU Foundation | Described in the 2024 announcement as building EDU Chain. |
| Arbitrum Foundation | Grant provider and ecosystem supporter; not identified as the chain’s operator. |
| Animoca Brands | Launch partner; the announcement identified executive chairman Yat Siu as a member of the EDU Foundation Council. |
| Gelato | Rollups-as-a-Service infrastructure provider identified in EDU Chain’s developer documentation. |
Calling EDU Chain “an Arbitrum chain” can refer to its technical framework or settlement arrangement, but it should not be confused with Foundation ownership or operation.

How EDU Chain fits into the blockchain stack
EDU Chain is presented as a Layer 3, or L3, network built using the Arbitrum Orbit Stack. In the general architecture described for the project, Ethereum provides the base settlement environment, Arbitrum is a Layer 2 scaling network, and EDU Chain operates above that infrastructure as an application-specific chain. The current EDU Chain developer documentation lists Arbitrum as the mainnet settlement layer and identifies the Orbit Stack and Gelato RaaS.
A dedicated L3 is intended to give a particular ecosystem room to configure infrastructure around its applications rather than sharing every resource with a general-purpose chain. The project’s stated aim is to support education-related apps, potentially with lower costs or less competition for capacity than on a broader network. Those are design goals, not a guarantee of a specific fee, throughput, or user experience.
An L3 does not automatically have exactly the same security properties as Arbitrum One. The full picture depends on such details as settlement, data availability, operators, bridges, and governance. The cited documentation establishes the stated framework and settlement relationship; it is not by itself a complete independent security audit or account of every operational trust assumption.
What an education-focused chain is intended to do
Open Campus describes its model as “Learn Own Earn”: learners could record achievements on-chain, educators and content creators could receive recognition or rewards, and developers could build applications around credentials, badges, identity, education finance, and learning records. These are intended uses, not proof that credentials are widely accepted or that the applications have broad adoption.
Open Campus’s 2024 announcement said its network included more than 60 education and Web3 partner companies, collectively representing 20 million learners. That figure describes claimed partner-network reach; it does not mean 20 million people were using EDU Chain, holding EDU, or receiving on-chain credentials. The available sources do not provide a complete, independently verified dashboard for active wallets, transactions, issued credentials, paying institutions, or deployed applications.
A blockchain record can help show that information was recorded or attested, but it cannot alone establish that an institution is legitimate, that a learner completed work honestly, or that a credential is recognized by an employer or school. Those questions depend on the issuer, verification process, revocation arrangements, and acceptance by the people who need to rely on the credential.
Current mainnet and testnet configuration
The official documentation updated July 16, 2026, lists separate mainnet and testnet configurations. Network parameters can change, so developers and users should check the documentation before configuring a wallet or application.
| Network | Settlement layer | Chain ID | Currency symbol | RPC endpoint | Explorer |
|---|---|---|---|---|---|
| EDU Chain mainnet | Arbitrum | 41923 |
EDU |
https://rpc.educhain.xyz | https://explorer.educhain.xyz |
| EDU Chain Testnet | Sepolia | 656476 |
Not stated in the cited documentation | https://rpc.testnet.educhain.xyz | https://explorer.testnet.educhain.xyz |
The documentation provides a mainnet configuration, but the materials cited here do not establish a precise mainnet launch date or demonstrate broad production use. A live configuration is evidence that developers have network details to work with, not a measure of adoption, liquidity, or institutional deployment.

The developer portal lists guides and integrations for building and deploying smart contracts, Open Campus ID, achievements and badges, bridging, indexing, oracles, relays, and wallets. Its navigation includes LayerZero, Goldsky, DIA, Gelato Relay, Privy, and Web3Auth. A listed guide or integration is not proof that a service is production-ready, free, permanently supported, or equally decentralized in every configuration.

For a developer, the practical question is whether EDU Chain’s dedicated environment, tools, and intended audience fit a specific application better than deploying on a general-purpose chain. For an institution, the decision also involves privacy, identity assurance, accessibility, integration with student-information systems, legal review, and support commitments. Educational records can be sensitive: putting a hash or identifier on-chain does not by itself address consent, correction, deletion, or data-protection obligations. No compliance status should be assumed without a specific statement covering the relevant system and jurisdiction.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Using the documented bridge
The official asset-bridging guide describes a mainnet route from Arbitrum One to EDU Chain Mainnet, and a testnet route from Arbitrum Sepolia to EDU Chain Testnet. Before signing, verify the bridge address or portal through the official documentation, confirm both network selections, and check that the asset is supported by the destination application. Bridge transactions can be difficult or impossible to recover if sent through a fake site or to the wrong network.
- For mainnet, open the bridge portal linked from the official documentation and connect a compatible wallet.
- Select Arbitrum One as the source and EDU Chain Mainnet as the destination.
- Enter the amount, review the asset and destination, and sign the transaction. Allow for network congestion and fees; the guide says users need enough ETH for transaction costs.
- After confirmation, switch the wallet to EDU Chain and verify the transaction in the documented explorer.
For testing, use the testnet bridge and select Arbitrum Sepolia as the source and EDU Chain Testnet as the destination. Use testnet funds, not assets you intend to spend. The cited guide does not provide a complete asset-support matrix or promise recovery for funds bridged incorrectly.

What the Arbitrum connection does—and does not—signal
Foundation support can matter by connecting a project with funding, developer incentives, hackathons, ambassadors, and Arbitrum tooling. The Orbit framework and documented Arbitrum settlement also give EDU Chain a defined technical relationship to the wider stack. Neither the partnership nor the architecture establishes that schools will adopt the network, that its token incentives will be sustainable, or that its services will meet every institution’s requirements.
Important questions for any prospective user or builder include who controls upgrades and bridge administration, how operators and data availability are configured, what happens if a service provider changes, and whether target schools or employers will recognize the resulting records. Token rewards can motivate participation but may also invite speculation, low-quality activity, sybil abuse, and regulatory complexity. Cross-chain tools and hosted integrations add dependencies that need to be assessed against an application’s security and operational needs.
