How did you do your security audits for smart contracts?

Smart contracts are necessarily contracts which are written in codes. These are deployed on the Blockchain Platform. The smart contracts are self-executing, codes that also negotiate, enforce transactions or even actions.

Once deployed on the blockchain platform, it is impossible to edit or manipulate them at any cost. Not even the admin who created it can tamper the codes. Hence it is highly essential to check the codes before deploying the codes.
