| Introduction to Solidity and Debugging | Patrick McCory, Patricio Palladino | 01h 42m |
Step‑by‑step Solidity 0.6.1 demo builds a censorship‑resistant “hello world” that emits events and then a mutable bulletin board that stores messages… | ||
| Code your first flash loan | Emilio Frangella, Ernesto Boado | 29m |
Explains how Aave’s flash loans actually work: the lendingPool sends funds to a flash loan receiver which must call executeOperation and return principal plus… | ||
| Designing Ethereum UX for Humans | Jason Goldberg, Simona Pop | 29m |
An app-level SDK built over four years deploys a per-user smart-contract wallet (a multi‑sig on layer‑2) so every tap can move value: likes convert to one-cent… | ||
| Build a trading bot you can use today | Will Harborne | 19m |
Shows a working Dex API and a JavaScript client that lets a local bot place orders via a WebSocket market feed, sign trades with a separate Stark key and… | ||
| Hacking ENS | Makoto Inoue | 33m |
ENS predates the NFT boom but a 2019 upgrade makes .eth names ERC-721 minting so hundreds of thousands of names trade on OpenSea; about 400,000 names exist and… | ||
| DeFi Composability with Aave Flash Loans | Ernesto Boado | 27m |
Describes Aave flash Loans as atomic, undercollateralized borrows used for liquidations, instant leverage, position swaps and arbitrage; implementation puts a… | ||
| How Does A STARK Proof System Work | Michael Riabzev | 28m |

| AirScript: Arithmetization for zk-STARKs | Bobbin | 18m |
AirScript defines execution traces as dynamic and static registers, transition functions and constraints, and compiles to Air assembly consumed by the genSTARK… | ||
| The Network Glue | Mara Schmiedt, Collin Myers | 28m |
Claims that proof‑of‑stake needs an application‑layer “glue” and shows a prototype called Activate that connects token holders, delegators and validators… | ||
| Scalability Solutions from zk SNARKs | Mary Maller | 27m |
zk SNARKs allow an aggregator to post a short proof instead of full transaction data, enabling zk-rollups and projects like Coda to compress history so a… | ||
