Lesson role

QUIZ

Sequence

8 / 15

Quiz — Network

Question

Confirm: 10 associated types, 4-state tx split, Ethereum/Optimism impl differences (8/10 differ), TransactionBuilder<N> helper, AnyNetwork escape hatch.

Principle (minimum model)

10 associated types + 4-state tx split + Ethereum/Optimism delta + TransactionBuilder<N> + AnyNetwork.

Worked example + steps

Quiz: did the `Network` trait shape stick?

Four questions covering the design decisions across the buildup and walkthrough. Same rule as the other Intermediate quizzes: you can't nod past a quiz.

If you miss two or more, scroll back to Building the Network trait step by step before going on to the drill.

Summary (3 lines)

Quiz confirms Network trait understanding.
Get two+ wrong → re-read buildup + walkthrough.
Pass → drill: generic-over-N code that works on Ethereum AND Optimism.
