This newsletter is sponsored by Pashov Audit Group!
Are you developing a blockchain protocol? Make sure to get a high-quality audit. Audits are not silver bullets, but a good one drastically decreases the chances of a successful attack. An “internal review” by your developers is not an audit. Without a formal one many users won’t trust your protocol because you are putting their funds at risk.
In Pashov Audit Group we know for a fact that we can help you secure your code in a painless, high-quality and express manner. We are looking for established projects who invest in security and are looking for the highest quality security partner.
We still have a couple of slots available over the next couple of months. Reach out for security help – pashov.net
