‘Transaction Operations for a Common Token Transfer

When it comes to Ethereum, the first thing that comes to mind may well be “gas fee”. Nowadays, the mainnet of major blockchain projects are online, and their synonyms for ‘transaction fees’ are often inseparable from the word “gas”.

The high gas fee has always been a sore point for blockchain transactions, especially for smaller scale investors. With the increase of blockchain projects and the expansion of the market, the number of transactions on the blockchain and the average gas consumption of transactions has increased.

Here we can insert some historical data of Gas price

In his early days, Minzhi never thought he’d become a Security Engineer for the largest crypto and blockchain security company in the world. With a background in software engineering, and a desire for DeFi, Minzhi has built upon his skillset to become a Security Engineer with CertiK!

Below, Minzhi shares a day in the life, alongside his background, interests, and more.

Adrian is a self-confessed technology nerd and geek. From owning the Amiga 500 in his childhood, Adrian always loved computers and the potential of what you could do with them.

He developed his curiosity and hacker-mindset through playing video games and teaching himself how to hack or root devices he owned, from various game consoles through to iPods and smartphones (even before they were ‘smart’, too!).

Adrian’s journey into Blockchain started in 2016 where he worked on de-anonymizing Bitcoin transactions as part of the Innovation Exchange programme at BAE Systems. …

A Certified Version of the Uniswap V2 Contract: A Leap Forward in True Decentralization

With more than $500 million worth of tokens lost due to financial exploits in DeFi protocols during 2020, and $343m lost in the first 5 months of 2021 alone, security has been top of mind for all projects. A reputable audit report is the current standard, but that’s not always enough on its own. There are countless ways for hackers to exploit vulnerabilities, both technical and economic. This can be through manipulation of oracles (like in YFI), replay of transactions in mempools and front-running them, or implementation bugs in the pool contracts. But how can we reduce the damage? …

Security audits have cemented themselves as a necessary tool in the arsenal of every type of blockchain-based project when it comes to securing their protocol and, importantly, their user’s funds.

With the total value locked in DeFi alone exceeding $45 billion dollars in February of ’21 it’s no surprise that we’ve seen the demand for smart contract security audits and penetration tests rise in parallel.

To prepare for an efficient security audit there are a number of best practices the security team here at CertiK recommends.

Outlining the Scope of your Audit and your Goal(s)

First things first, let’s ask ourselves two questions:

What will be audited?

How will…

The CertiK Security Team has successfully completed an audit of XEND Finance’s smart contract’s delta related to the rewarding group creator. The code in the audit is comprised of code related to rewarding a group’s creator with a percentage of the commission fee as well as to track total $XEND token rewards. A summary of the audit and its findings follows up.

Use-Case Profile

As a decentralized Credit Union, Xend Finance (XF) serves to optimize, improve, and add value to the core operations of Credit Unions globally, while also allowing users to form their own cooperatives and pool their money, no matter…

CertiK has set out on a joint strategic venture alongside Convergence Finance to ensure the security of their protocol and wider ecosystem. With Converge Finance’s security-centric approach, something which is naturally shared by CertiK, we’re confident that the team have paved the way for a deep level of trust and reliability in their project.

Convergence — Secured by CertiK

As part of the strategic partnership, the Convergence protocol underwent a thorough audit by a team of security experts at CertiK HQ. The audit leveraged a combination of static analysis and manual review and was focused on ConvX, Convergence’s decentralized interchangeable asset protocol.

How to Make the Most of Remote Work

In March 2020, the working life for many of us changed drastically. Water cooler catch-ups turned into Slack powered instant messages, whilst the weekly meeting was powered by Zoom and the boss didn’t know you’re still wearing your slacks on your lower half.

Echoing the distributed nature of blockchain, the CertiK team have worked from a variety of locations around the world from day one.

Remote working can be, and has been, a huge change for a lot of us. …
