I have built a token using ERC20PresetMinterPauser from Openzeppelin and published it to the ropsten public network about 3 months ago. I plan to publish the token to the mainnet, but it is advisable to do a security audit. my questions are:
- How do I perform a security audit from Openzappelin?
- How much do I have to pay for the service?
Thank you in advance.
