Why focusing on price is giving a completely wrong overview of the blockchain protocols?

Since my early days as a smart contract developer, I was fascinated why people are more focused on the token price than what the token actually offers? The answer is quite simple: people want to get rich, and when they put their savings into the project or cryptocurrency, they want

Where can blockchain help?

Blockchain has been "promoted" as a technology that can help in multiple areas. Still, mainly, people are talking about Blockchain when they talk about cryptocurrencies, prices of BTC/ETH, and new altcoins that want to change the world 🙄. There is so much more to the Blockchain than just that. I

PancakeBunny exploit used for the 3rd time

PancakeBunny exploit used for the 3rd time

When I wrote about PancakeBunny exploit, [https://www.adrianhetman.com/pancakebunny-hacked-for-40m/] I didn’t think I would be reporting the same hack for the 3rd time. But that’s our reality when projects fork another project’s code without changing much. Without even trying to stop the protocol and fix

AutoShark hacked for ~$745k

AutoShark hacked for ~$745k

Bunnies are reproducing quite fast, and as it turns out, not only in nature but also in the blockchain. Autoshark was nearly 1:1 fork of PancakeBunny, and apart from copying all the logic, they also copied the flawed logic responsible for the PancakeBunny hack. A hacker used 100K BNB

Is anybody safe from hackers in DeFi?

Another day, another hack. For some time, it was relatively calm. I mean somewhat as DeFi space had more than two days time span between hacks. On the 12th of May, XToken has been hacked for around $24M. Yup. Adding only hacks that have happened in May, ~$85M were stolen.

This will be a continuation of a rant on how clients should prepare for an audit. [https://www.adrianhetman.com/how-to-prepare-for-a-security-audit/] Opinions and views are my own if you haven’t catch that 😉 I’ve been auditing smart contracts for 8 months now. I’ve seen my fair share of

How to prepare for a Security Audit

DeFi space is growing strong, TVL is growing even faster, and the stolen value from DeFi protocols. According to DeFi Pulse [https://defipulse.com], the Total Value Locked in DeFi projects is roughly $80.78B. $80.7B... That’s $15B more since I brought that number up in my article

Intro to DeFi

This won’t be a long post as I don’t want to reinvent the wheel and re-tell the same story as many people have told it much better than I even could. I will do a really brief introduction to DeFi for those who don’t know what it

In the upcoming London hard-fork, scheduled to happen in July, one significant change London is bringing is the inclusion of the famous EIP-1559. The gas killer, the prodigy, the all-awaited change in the gas fee marketplace. In summary, EIP-1559 changes how gas fees work in Ethereum. From the current system

What the EIP/ERC!?

What the EIP/ERC!?

In Ethereum world ERC-XXX or EIP-XXXX phrases comes up quite often but for people new to the Ethereum world, this looks quite cryptic. What is EIP?

War on Gas

The main issue haunting the Ethereum network is gas prices for each transaction. High gas prices caused many problems and bizarre situations like Kings of Leon’s NFT were cheaper than a transaction cost when the release of their NFT. It's a massive problem for Ethereum making the applications more

Can you spot Blockchain in the wild?

When people often talk about Blockchain (it’s a common topic within a group of friends, give me a break), they often talk about cryptocurrencies, DeFi and NFTs. Not many people explore what’s possible besides that. Still, I’m here to tell you some companies use Blockchain in a

Imagine a scenario where a hacker successfully steals money or stocks from some financial institution or maybe from hacking credit cards. A hacker stole $1.5 million in the total value of money. A scenario like this would potentially end up discussed on TV or some major media outlets. Imagine

Finding a job is not always an easy task unless you’re super talented and have a ton of experience. But even people like that started from scratch. The question is, what did these people have done to get where they are? How did they got into that ? I don’
