RPC Selector автор Slime

In Web3, decentralization is one of the main benefits. But it has a bottleneck - RPC servers are all centralized, and usually hardcoded in the websites you use. This extension can be used to redirect all RPC calls to a custom RPC server.

It's a fork of https://addons.mozilla.org/en-US/firefox/addon/redirector/, and source code is available at https://github.com/Sliman4/rpc-selector
