On June 24, 2022, Horizon, the cross-chain bridge between Ethereum and Harmony, was attacked with a loss of approximately $100 million.

With the development of blockchain technology, more and more hacking incidents continue to affect the industry. Since there are many cases of theft due to bugs in smart contract codes, projects and users have to be more careful, and on the other hand, the role of auditing companies becomes more and more important.
What is a smart contract? Why do smart contracts need to be audited?
A smart contract is a computer program that uses blockchain technology to digitally facilitate, validate or enforce the negotiation or performance of a contract. Smart contracts allow for the validation and execution of trusted transactions without a third party. These transactions are verifiable and irreversible. The code of a smart contract is stored on the public ledger and once triggered, the contract cannot be changed or stopped.
Smart contracts are programmed and deployed to the blockchain. Once deployed, there is no turning back. One small mistake can break the entire protocol and drain the whole pool. In the last two years alone, billions of dollars have been lost due to vulnerabilities in smart contracts. And with auditing, most contract vulnerabilities can be avoided.
