So what is The Graph Protocol all about? Why do some people call it the Google of Blockchains? And what is the use case for the GRT token? You’ll find answers to these questions in this article.

Let’s start with what The Graph actually is.


The Graph is an indexing protocol for querying blockchain data that enables the creation of fully decentralized applications.

The project was started in late 2017 by a trio of software engineers who were frustrated by the lack of tooling in the Ethereum ecosystem which made building decentralized applications hard. …

So what’s the story behind Decentralized Finance? How has all of this started? What happened in DeFi in 2020? And where are we going in the future? You’ll find answers to these questions in this article.

Let’s start from the beginning.

Although there is no one agreed-upon date when decentralized finance was born, there were a few important events that made DeFi possible.


The first of them was the creation of Bitcoin in 2009 by Satoshi Nakamoto.

Despite whether Bitcoin should be classified as DeFi or not, its inception was the key enabler for the whole cryptocurrency industry which decentralized finance is part of. …

So Bitcoin on Ethereum — a good or a bad idea? What are the use cases for moving your precious BTC to Ethereum? What are the risks? And what are the protocols that make all of this possible? You’ll find answers to these questions in this article.


Okay, so let’s start with why someone would want to move their Bitcoin to Ethereum in the first place?

The short answer is decentralized finance. Let’s try to understand why this is the case.

DeFi took the whole crypto space by storm, showing that payments is not the only area of finance that can be decentralized. In fact, DeFi focuses on rebuilding all financial services in a completely decentralized, open and permissionless way. On top of that, it allows for creating financial applications that were previously just impossible to make. …

So what are the top 3 DeFi-friendly wallets? What features do they support? And what are the pros and cons of using each of them? We’ll answer all of these questions in this article.

Cryptocurrency Wallets

Wallets, in essence, allow for sending, receiving and storing cryptocurrency.

They come in many different shapes and forms, but the most popular options are:

  • a browser extension
  • a hardware wallet
  • a mobile app
  • or a web wallet

DeFi-friendly wallets facilitate managing your digital assets and interacting with DeFi applications such as decentralized exchanges or lending and borrowing protocols.

Let’s start with a wallet that most DeFi users are very familiar with — Metamask. …

So have you ever been wondering how lending and borrowing works in DeFi? How are the supply and borrow rates determined? And what is the main difference between the most popular lending protocols such as Compound and Aave? We’ll answer all of these questions in this article.

What Is Lending and Borrowing

Let’s start with what lending and borrowing is.

Lending and borrowing is one of the most important elements of any financial system. Most people at some point in their life are exposed to borrowing, usually by taking a student loan, a car loan or a mortgage.

The whole concept is quite simple. Lenders a.k.a. depositors provide funds to borrowers in return for interest on their deposit. Borrowers or loan takers are willing to pay interest on the amount they borrowed in exchange for having a lump sum of money available immediately. …

So what is Ethereum Layer 2 scaling all about? And what is the difference between projects such as Optimism, xDai, OMG and Loopring? We’ll answer all of these questions in this article.

Need For Scaling

Ethereum scaling has been one of the most discussed topics pretty much since the time when the network launched. The scaling debate always heats up after a period of major network congestion.

One of the first periods like this was the 2017 crypto bull market where infamous CryptoKitties, together with ICOs, were able to clog up the entire Ethereum network causing a major spike in the gas fees.

This year the network congestion came back even stronger, this time caused by the popularity of DeFi and yield farming. …

So is Yield Farming dead? Are there any good farming opportunities left? And when are 1000% APYs coming back? We’ll answer all of these questions in this article.

Yield Farming & Liquidity Mining

Before we jump into the main topic, let’s quickly recap what yield farming actually is.

Yield Farming, in essence, is a way of trying to maximise a rate of return on capital by leveraging different DeFi protocols. Yield farmers try to chase the highest yield by switching between multiple different strategies. If the strategy doesn’t work anymore or if there is a better strategy available the yield farmers move their funds around. …

So what are flash loans all about? And how can they be used to borrow millions of dollars worth of crypto with no collateral? You’ll find answers to these questions in this article.


A flash loan is a feature that allows you to borrow any available amount of assets from a designated smart contract pool with no collateral. Flash loans are useful building blocks in DeFi as they can be used for things like arbitrage, swapping collateral and self-liquidation.

Flash loans, although initially introduced by the Marble protocol, were popularised by Aave and dYdX.

So, what’s the catch?

A flash loan has to be borrowed and repaid within the same blockchain transaction. …

So what are NFTs all about? And how can they be used in decentralized finance? You’ll find answers to these questions in this article.


Okay, so let’s start with what NFTs actually are.

NFTs stand for non-fungible tokens and they are one of the types of cryptographic tokens that can represent ownership of digitally scarce goods such as pieces of art or collectibles.

“Non-fungible” is not a very popular word so let’s see what it really means.

In economics, fungibility is the characteristic of goods or commodities where each individual unit is interchangeable and indistinguishable from each other.

Like with most concepts, fungibility is best explained with an example. …

So what’s the story behind Uniswap — one of the most important protocols in DeFi? And why was the UNI token probably one of the best-distributed tokens ever? You’ll find answers to these questions in this article.


Uniswap is clearly one of the most important and the most discussed projects in the defi space. At its core, Uniswap is a protocol for decentralized exchange of tokens on the Ethereum blockchain. The Uniswap protocol is deployed as a set of smart contracts and it’s completely decentralized, permissionless and censorship-resistant.

Uniswap is built on the concept of liquidity pools and automated market makers or, to be precise, a constant product market maker. If you’d like to learn more about the mechanics of the protocol, check out my article on liquidity pools which uses Uniswap as an example. …
