Recommendation of ETH Public RPC Nodes

Ethereum (ETH) is an open-source platform based on blockchain technology that supports smart contracts, decentralized applications (DApps), and functions such as cryptocurrency token issuance. As a distributed system, the Ethereum network consists of numerous nodes and provides a way to communicate with other nodes through a public Remote Procedure Call (RPC) interface. RPC can be understood as an entry point for accessing the blockchain network, much like a door. All transactions on the ETH chain require this door to be accessed. This article will introduce public RPC nodes for Ethereum.

What is an Ethereum public RPC node?

An Ethereum (ETH) public RPC node is a way to interact with the Ethereum network, allowing developers to query blockchain data, broadcast transactions, and execute smart contracts through RPC. These nodes are hosted by various service providers and can be connected to via HTTP or WebSocket protocols, communicating with the Ethereum blockchain network (ETH Mainnet) through the JSON-RPC interface provided by the nodes.

Why do we need Ethereum public RPC nodes?

When interacting and trading on the blockchain, programs need to communicate with the Ethereum network. Running a complete Ethereum client on one’s own node as a developer when developing DApps and smart contracts can be resource-intensive and time-consuming. Instead, using public RPC nodes can allow for faster data retrieval and transaction execution while saving costs associated with deploying and maintaining an Ethereum node.

During times of ETH congestion, switching public RPC nodes and selecting RPC entry points with lower latency can reduce delays, avoid traffic jams, increase transaction speed, and gain a competitive edge. It is important to note that switching RPC nodes does not necessarily reduce gas fees. RPC solves the problem of access to the blockchain rather than addressing the overall performance and cost issues of the entire chain.

What are some commonly used public RPC nodes for Ethereum?

https://mainnet.infura.io – Infura is a hosted node service for Ethereum and IPFS that provides RPC nodes for the Ethereum mainnet and test networks.

https://cloudflare-eth.com – Cloudflare provides an Ethereum mainnet RPC node.

https://api.mycryptoapi.com/eth – MyCrypto API provides an Ethereum mainnet RPC node.

https://rpc.slock.it/mainnet – Slock.it provides an Ethereum mainnet RPC node.

https://eth.rpc.rivet.cloud – Rivet provides an Ethereum mainnet RPC node.

https://mainnet-rpc.dexon.org – Dexon provides an Ethereum mainnet RPC node.

https://eth-mainnet.alchemyapi.io/v2/{API_KEY} – Alchemy provides an Ethereum mainnet RPC node, with private API key available upon request.

https://rpc.moonriver.moonbeam.network – Moonriver provides an Ethereum mainnet RPC node.

https://eth.rpc.tor.us – Torus provides an Ethereum mainnet RPC node.

https://mainnet-rpc.thundercore.com – ThunderCore provides an Ethereum mainnet RPC node.

https://rpc.ankr.com/eth – Ankr provides an ETH mainnet RPC node. The paid version also supports the WebSocket protocol.

All of these nodes are provided by relatively well-known and secure vendors, such as Cloudflare. By utilizing their service scheduling and edge computing networks, they can achieve faster and closer access to the ETH network, enabling transactions. When selecting a node, I generally conduct speed tests on all of them and choose the one with the lowest latency. Additionally, nodes like Alchemy that require users to apply for an API key have fewer access requests compared to other nodes, so their speed can be faster.
