Why you should build on OpenEthereum

High Performance

Finely tuned & optimised use of the fast Rust language EVM turbocharges execution of complex contracts Multi-level in-memory caching.

Easy to use

1-line installers for Mac and Linux with fully documented Library APIs.

Ultra Reliable

Memory and concurrency safety guaranteed by Rust language actor-based modularity ensures maximal resilience.

Small Footprint

Rust's ownership tracking facilitates minimal memory footprint cache management gives fine control to user state-trie pruning minimises storage footprint.

Tested from Day 1

From RLP and the Trie to the network subsystem. We aim for our unit tests to cover 100% of critical logic.

100% Reviewed

Core code in codebase is fully reviewed by auditing firm Trail of Bits and every line of code is routinely reviewed by two expert developers.
