eRPC

eRPC is an open-source, fault-tolerant EVM RPC proxy featuring permanent caching.

It is built for read-heavy use-cases such as data indexing and high-load frontend applications, where consistent RPC access matters.

The design emphasizes lowering costs through local caching while improving reliability during provider outages.

It also provides visibility into RPC usage across teams and third-party providers, enabling better oversight of how RPC resources are consumed.
