OpenEthereum’s goal is to be the fastest, lightest, and most secure Ethereum client. We are developing OpenEthereum using the cutting-edge Rust programming language. OpenEthereum is licensed under the GPLv3 and can be used for all your Ethereum needs.
By default, OpenEthereum runs a JSON-RPC HTTP server on port
:8545 and a Web-Sockets server on port
:8546. This is fully configurable and supports a number of APIs.
