Hi everyone,
Over the past several months, we engaged several 3rd party security firms (including NCC Group, Trail of Bits) to conduct security audits on the Stacks Blockchain, as well as the Stacks Wallet.
You can find the reports from these audits, along with the status of each reported vulnerability here.
TL;DR is that all high/medium (and several low) severity findings have been fixed. Overall, there were no findings that were high-severity and high-likelihood.
Thanks,
Diwaker
