Top 7 Crypto Audit Companies

With attacks on the increase, security is critical in the crypto world. Smart contracts are one key component that must be audited. These are self-executing computer programs that include the conditions of a contract between the buyer and seller encoded in lines of code.

These contracts are housed and performed on the blockchain via a computer network, making transactions traceable, transparent, and irrevocable.

Vee Finance, a Slowmist-audited protocol on Avalanche, was struck for $34 million owing to broken contracts. According to Slowmist, the problem arose when the attacker utilized this to alter the price of the Pangolin pool, which acts as the price oracle for Vee Finance, causing the pre-swap slippage check to fail.


The QuantStamp platform, founded in 2017 by Richard Ma and Steven Stewart, is aimed at auditing Ethereum smart contracts for flaws or possible vulnerabilities. QuantStamp is one of the largest smart contract audit companies.

The $31 million MonoX protocol compromise examined by Halborn is another multi-million dollar hack in the DeFi industry, ranking 22nd in size.

The attacker was able to take advantage of the price update mechanism, which enabled the hacker to artificially boost the price of the MONO tokens.
