ZKsync OS

Immunefi · Pays the most of the 2 programs: up to $100,000.

Amounts are the top reward per severity in the currency each program pays. Green marks the highest per severity. First response is the platform's measured average when it publishes one, else what the policy promises.

What is in scope

246 targets across all 2 programs, each listed once with the programs that cover it. 10 excluded.

About this page

This page gathers every public program listed under zksync.io: platform programs, self-hosted policies and security.txt contacts. Each program's own policy decides what is in scope and what it pays; check it before you test.
