Why a Bug Bounty Program?
An audit is a snapshot. It reviews your code at a single point in time, then your codebase keeps evolving and the coverage ends. A bug bounty program keeps thousands of skilled researchers examining your live code around the clock, for as long as your program runs.
of long-running bug bounty programs on Immunefi have surfaced at least one critical vulnerability. The question is not whether a critical bug exists in your code. It is who finds it first.
