You might have heard of the infamous “Yul” assembly language for the Ethereum Virtual Machine (EVM). But what if I told you there was a language even lower level than that? Overview Yul is the assembly language of choice for many smart contract engineers looking for lower level control in the…

Foundry is the new EVM development environment on the block. With Solidity-native testing, powerful CLI’s, and high-performance Rust tools, Foundry is more than worth your time to learn. Installation The official installation guide can be found here. Personally, I had trouble getting anvil with foundryup, so if you want to build…

Reactive smart contracts are smart contracts that can react to certain events using a type of function called a callback. In this article we will explore why smart contract reactivity is powerful and how it differs from common patterns used in the Ethereum Virtual Machine. This will be high…

The Superfluid architecture facilitates unique token interactions with agreements. The Constant Flow Agreement has the big one-liner pitch, “real-time token streaming”, but what about the other one? The Instant Distribution Agreement makes recurring distributions to arbitrary numbers of addresses highly scalable. …

In this article, I will be writing and breaking down a simple smart contract in both Solidity and Yul for a side-by-side comparison on the syntax. A beginner to intermediate understanding of Solidity and the Ethereum Virtual Machine (EVM) is assumed for the scope of the article. Overview For the scope…

If you’ve been around the Superfluid ecosystem, you’ll know that super tokens are revolutionary assets, but if you’ve tried deploying one yourself, you’ve probably either used their script for convenience at the cost of having no unique functionality and being unable to deploy from another contract, or you’ve tried to…

This the second of a series of walkthroughs on the DVDF smart contract war games. If you missed it, here is the start of the series with some basic setup instructions. Challenge #2 — Naive Receiver “There’s a lending pool offering quite expensive flash loans of Ether, which has 1000 ETH in balance. You also…

This is the beginning of a series of walkthroughs on the Damn Vulnerable DeFi smart contract war game. This has been a lot of fun so far, and I’m looking forward to documenting my analysis, exploit development, and reviewing the vulnerabilities for newcomers to smart contract security. …

The Graph is an indexing protocol for NEAR and EVM compatible blockchains. This article will not focus on The Graph itself, but rather, using it in the context of Superfluid. GraphQL GraphQL is an open-source data query and manipulation language developed by Facebook in 2012. The GraphQL syntax allows data consumers…
