Designing Bridges — Lesson overview

What we’ll buildA minimal bridge skeleton that locks tokens on Chain A, emits proofs, and releases/mints on Chain B with replay protection and verifier checks.

Why start simpleReal bridges are complex (light clients, multi-sigs, rollup proofs). A scoped, auditable core makes trust assumptions explicit before you layer features.

DeliverablesFormulas for safety checks, stepwise code snippets, and a full reference contract you can test/fork.
