If you’ve spent a few weeks developing smart contracts on the Ethereum network, you’ve likely encountered a frustrating limitation: the lack of historical onchain data. Without this information, it’s difficult to make informed decisions or develop strategies based on past performance. Oracles, such as Chainlink and Uniswap aim to provide…

The evolution of crypto and technology in the next 100 years is a mystery that remains unknown. Yet, on a dull and rainy day, it can be inspiring to imagine the possibilities. Following are the mere speculations for a world called “Cryptopia” 😎. The dawn of crypto (2030) Cryptocurrency has taken off in BRICS and…

In the realm of decentralized finance, there are numerous phenomena to which we have grown accustomed. While some of these occurrences prove beneficial, others may be detrimental. One such unfavorable phenomenon is the concept of impermanent loss, which poses significant challenges for AMM liquidity providers. Every liquidity provider, myself included…

TLDR Check out this repository on GitHub: https://github.com/alexeuler/ethereal Intro The other day, I was trying to obtain some contract events for statistics. I usually use web3.py for this purpose, but I every time its a bit tedious to download contract abi, convert dates to blocks, verify checksum addresses, and deal with the…

Automated Market Makers (AMMs) have revolutionized the way we trade cryptocurrencies by providing an automated way to buy and sell assets without the need for a traditional order book. However, as the DeFi ecosystem grows and becomes more complex, liquidity management has become increasingly important. …

In this article, we will dive into a specific problem that DeFi builders face — how to avoid MEV without using offchain data. We will focus on transactions such as swaps and liquidity provision on popular AMMs like Uniswap, Curve, Kyber, and Quickswap. Today, MEV protection is typically achieved using…

In the previous article, “Feeding Uniswap with AAVE” I discussed a strategy that enables users to enter Uniswap by providing only ETH as liquidity and borrowing USDC using AAVE. To recap briefly, the steps involved in this strategy are as follows: Begin with a certain amount of ETH, such as…

Introduction Have you ever wondered if it’s possible to enter Uniswap with only one token? Well, there’s a solution that does just that. By providing only ETH as liquidity and borrowing USDC using AAVE, you can maximize yields in the ETH/USDC Uniswap pool. However, determining the exact amount of USDC to…

Intro As DeFi continues to evolve, it’s getting tougher to determine the risk/returns profile of emerging primitives. One such primitive is the Uniswap V3 vault with incentives, which takes liquidity from depositors (LPs) and places it into a specific price range within the Uniswap V3 pool. …
