RLN on KZG in Golang

A proof-of-concept implementation of RLN (Rate Limiting Nullifier) using KZG in Golang. This implementation is grounded in the discussion at zkresearch initiated by Wanseob Lim.


This application allows you to freely explore DApps, impersonate any user, inspect transaction traces, manipulate time by turning the clock forward or backward, and easily construct and simulate Gnosis Safe MultiSend transaction bundles. A lite version, known as MferSafe Lite, is also available as a browser extension.
