After careful consideration, we’ve made the decision to wind down @code4rena. This community has meant a great deal to everyone who has been part of building it, and sharing this news is not easy.

One of our whitehats just saved a project from total funds loss! He found a critical bug in a recently started bug bounty and now has enough funds to continue bug hunting for a year! 2 months ago we started working with whitehats, giving them coaching and tools, we're confident these people will have a positive impact in the space and look forward to sharing more. If you're an aspiring whitehat, with 6 months of funds to sustain yourself, reach out and we will consider you for the next batch.
