See where to go, what to look for, and more on your #crypto journey at: https://certik.com https://www.youtube.com/c/GirlGoneCrypto Transcript: Okay so let’s say you’re checking out a project and are doing your research and you see that it’s been audited. Great, phew, sigh of relief… but hold up… just because a smart contract was audited doesn’t necessarily mean the audit was good. When doing your own research, it’s important to go one step further and actually check out the audit report. Now reading audit reports might sound a little complicated and technical, but it’s actually a lot easier than you think. So in this video, we are going to dive into how to read and evaluate a CertiK audit report. So first of all - what kind of information do these reports actually look at? A security audit is a line-by-line inspection of a smart contract's code. Smart contracts are self-executing agreements between a buyer and seller that are stored on a blockchain. Security audits can reveal vulnerabilities in a smart contract by identifying coding errors and potential risks. CertiK essentially examines these smart contracts and blockchain ecosystems. CertiK’s security experts manually review these contracts, using AI solutions and mathematical approaches to analyze their quality. So now let’s dive into the HOW. Where do you go to find this information and what should you be looking for? When you visit CertiK.com, you’ll notice a search bar on their Security Leaderboard. Type in the name of the particular project you’re interested in. This will take you to the project’s full audit report. Under the Findings section, check to see that the vulnerability issues have been identified and fixed. If a project has unresolved issues, it’s important to research why. CertiK only audits contracts sent to them, so make sure to check which contracts were audited and always review the report in detail.

Episode 10: What is an Online Attack? Learn about #onlineattacks and more in under 2 mins! https://certik.com/products/skynet Transcript: Through decentralization, blockchain technology can improve the safety of online activities. Many online attacks use Attack Vectors to exploit system weaknesses. DDoS, Eclipse, and a 51 Percent Attack are three common types. A DDoS, Distributed Denial of Service, attack, occurs when hostile hackers overload a network with requests. In blockchain, DDoS target crypto exchanges or mining pools. They disable a network's ability to serve users. Eclipse attacks control a single node inside an artificial environment. An attacker can manipulate communications with surrounding nodes to perform illegal transactions by isolating a node. When an assailant obtains control of 50% or more of a network's mining hashrate, it's called a 51 percent attack. The individual can submit fraudulent transactions, making the blockchain centralized. 51 percent attacks become difficult as a blockchain network increases in the number of honest nodes. Blockchain analytic tools such as CertiK’s Skynet help with online attacks by monitoring on-chain activity. To learn more about online attacks visit CertiK.com/resources.

Learn how a #flashloan works and more in under 2 mins! https://certik.com/products/skynet Transcript: A flash loan is an uncollateralized short-term loan. They are a new invention in the Defi space, introduced by the lending protocol, AAVE. A smart contract is used to borrow and repay flash loans in the same transaction. If a flash loan isn’t repaid in the same transaction, the transaction fails, making it as though the loan never happened. Flash loans present an opportunity for high-frequency and arbitrage traders with the ability to instantaneously access capital, allowing a trader to sell on one exchange and purchase on another. Arbitrage was more common when liquidity was low and exchanges didn’t share price feeds. Flash loans have been used to attack exchanges and protocols. This occurs when a malicious user takes out a flash loan from a lending protocol and uses the borrowed funds to manipulate prices on another protocol. Flash loan attacks are very lucrative because the attacker does not have to deploy a lot of capital to carry out the attack. Smart contract audits are a necessary first step in mitigating a flash loan attack. CertiK’s Skynet on-chain monitoring helps recognize these attacks in real-time and broadcasts community alerts on the Security Leaderboard. From smart contract audits to on-chain monitoring, there are tools in place to help projects build safer protocols from the ground up. To learn more about flash loans, visit CertiK.com/resources.
