The challenge of implementing Solidity stack traces

Duration: 00:24:30

Speaker: Patricio Palladino

Type: Breakout

Expertise: Advanced

Event: Devcon

Date: Invalid Date

Debugging is an unavoidable phase of the software development cycle, and the most frustrating and productivity wasting part of developing smart contracts. The essential tools that a programmer would use to debug code manually in a mature platform are missing or unstable in Ethereum or are unstable. These are easy debug logging (e.g. console.log) and stack traces. In addition, smart contracts development presents extra challenges, like testing code and smart contract code being written in different programming languages. In this presentation, we'll shed some light on how stack traces work in other platforms and the challenges we had to solve for building them for Solidity in Buidler. These include identifying the code behind each contract address, identifying the functions in the stack, recognizing Solidity's compilation patterns to improve error messages, and how to display them from your JavaScript tests.

Farcaster frames: building embeddable Ethereum apps

Frames are an open standard for creating embeddable, interactive apps in social media feeds and on the web. They help solve one of the hardest problems for Ethereum dapp developers: distribution. Although frames originated on Farcaster, it's now possible to build cross-platform frames that work on Farcaster, Lens, XMTP, and the open web. In this hands on workshop we'll introduce the core concepts behind frames and build a simple frame app that interacts with a smart contract.

Introduction to Snarks

Blockchains are a hostile world were all information is public and computations are expensive. A technology called zkSNARKs is coming to the rescue: It allows both a tremendous speedup in verifying the correctness of a computation while at the same time it hides the private details from prying eyes. This talk tries to give an idea about how and why it works.
