Speaker:

Type: Talk

Expertise:

Event: Devcon

Date: Jul 2026

Joseph Olutimehin, Blockchain Security Engineer, Coinbase Bridges between L1 to “EVM-compatible” / “EVM-equivalent” L2 chains have their security consideration due to subtle but impactful differences such as opcodes, precompiles, gas accounting, and execution semantics, which can introduce bugs invisible to unit tests. This talk unpacks those differences with an eye toward practical engineering risks and security design. https://defisecuritysummit.org/schedule
