# Protocol Security **Audit** CertiK has audited initial contracts:\ However, during Nemesis PRO Migration, the developers have updated some of the contracts: 1\) The main token contract (NMSP) received a "blacklist" function allowing admins to blacklist harmful addresses. Our community has repeatedly asked for this measure to stop front-running bots during token exchanges. 2\) The bond contracts received the "pause/unpause" function, the "set minimum bond price" function, and also some other minor fixes. These extra measures were added by the team in order to mitigate possible attacks on the bonds in the future. Please note; even though these updates were shaped as per the needs of the community and the team, they are likely to be identified as "major or critical level findings" during examinations.\ \ **KYC** Nemesis Network has AssureDeFi KYC for Helena Financial. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
