Ethereum Classic (ETC) relies on a network of nodes to process transactions, execute smart contracts, and query blockchain data. For users who prefer not to run their own nodes, public RPC endpoints provide a convenient alternative. This guide explains what these endpoints are, lists key providers, and outlines best practices for their use.
Understanding Public RPC Endpoints
Remote Procedure Call (RPC) endpoints are URL addresses that allow external applications to interact with a blockchain network. They serve as gateways for submitting transactions, deploying smart contracts, or retrieving data like account balances.
- Self-Hosted Nodes: Running your own node offers maximum security and control but requires technical expertise and ongoing maintenance.
- Public Endpoints: Third-party services operate nodes and provide public RPC URLs, simplifying access for wallets, miners, dApps, and developers. While convenient, this method involves trusting the provider’s infrastructure.
Public endpoints function similarly to cloud services, handling requests without users managing hardware. They are ideal for prototyping, testing, or lightweight use cases but may pose risks for high-value operations due to centralized control.
Key Endpoints for Ethereum Classic Networks
ETC operates two primary networks: the mainnet for production and the Mordor testnet for development. Below are the official RPC endpoints endorsed by the ETC Cooperative.
Ethereum Classic Mainnet
The primary endpoint for mainnet transactions and queries:
https://etc.rivet.linkMordor Testnet
The dedicated endpoint for testing applications and contracts:
https://rpc.mordor.etccooperative.orgThese URLs replaced previous endpoints in July 2023. Users must update their configurations to avoid service disruptions.
Alternative Endpoint Providers
Beyond the official URLs, several community-maintained lists offer additional options. These resources help distribute traffic and provide fallbacks if primary endpoints are unavailable.
Ethereum Classic Community List
The canonical resource for ETC endpoints, curated by the community:
https://ethereumclassic.org/network/endpointsThis list includes verified providers and is regularly updated to reflect network changes.
Chainlist Aggregator Service
Chainlist consolidates endpoints for multiple blockchains, including ETC. Its lists are crowd-sourced and widely used:
- Mainnet Endpoints:
https://chainlist.org/chain/61 - Mordor Testnet Endpoints:
https://chainlist.org/chain/63
Always verify endpoints from aggregators, as they may include unofficial or experimental URLs.
Best Practices for Using Public Endpoints
To balance convenience and security, consider these guidelines:
- Prioritize Official Sources: Use endpoints from trusted entities like the ETC Cooperative to reduce risks.
- Rotate Providers: Distribute requests across multiple endpoints to avoid overloading any single service.
- Monitor Performance: Track latency and reliability; switch providers if responses slow or fail consistently.
- Limit Sensitive Operations: Avoid submitting high-value transactions through public endpoints. For critical tasks, use a private node or dedicated service.

Frequently Asked Questions
What is an RPC endpoint in blockchain?
An RPC endpoint is a URL that allows software to communicate with a blockchain node. It enables functions like sending transactions or reading data without running local node software.
Why did ETC change its endpoints in 2023?
The ETC Cooperative migrated from ETHERCLUSTER to RIVET to improve scalability and reliability. The update ensures better performance for developers and users.
Are public RPC endpoints secure?
While convenient, public endpoints rely on third-party security. They are suitable for general use but less secure than self-hosted nodes for sensitive operations.
Can I use multiple endpoints simultaneously?
Yes, tools like load balancers or custom scripts can distribute requests across endpoints. This enhances reliability and reduces dependency on single providers.
How often should I update my endpoint configurations?
Check for updates quarterly or when network upgrades are announced. Subscribe to official channels like the ETC Cooperative blog for changes.
What happens if an endpoint fails?
Transactions may delay or fail. Always configure fallback endpoints in your application settings to maintain continuity.
Conclusion
Public RPC endpoints simplify access to Ethereum Classic networks but require careful selection and management. By leveraging official sources and community lists, users can ensure reliable connectivity for their dApps, wallets, and tools. For optimal security, combine public endpoints with private infrastructure when handling valuable assets.
