Redford Stage
Description

Many L2 networks on Ethereum use Geth to build blocks. We will look at the Geth codebase in order to understand changes made and how these codebases evolve. This is important to determine how updates are propagated and establish dependencies.

Smart Contract Families in Solidity

Talk
Wednesday, July 2nd 2025

Hepburn Stage
Description

We show how to express similar smart contract applications in Solidity in a systematic way, enabling simultaneous code reuse across possibly incompatible chains (e.g., L2s). Our work helps developers to simplify multi-chain development and audits.
