Reputable Web3 auditing firms
Below is a list of reputable and high quality smart contract security firms. Keep in mind the top firms can have a backlog of 3-6 months, so plan your security review in advance. You can also get very cheap quotes from less reliable firms like certik or peckshield, but these two firms in particular are commonly considered to do “rubber stamp” audits and many contracts they have reviewed were later hacked.
