Going cross-chain? Five things we learned the hard way

01 — Rebuild the logic for each chain

Solidity and Rust handle accounts and state differently. Rewriting the logic from first principles is safer than translating the code line by line.

02 — Use burn-and-mint for cross-chain NFTs

Burn the NFT on the source chain and mint it on the destination chain. This keeps the total supply accurate and reduces the bridge's attack surface.

03 — Plan the dual-chain frontend early

Supporting two account models and two wallet flows in one interface often takes longer than the contracts themselves. Include it in the timeline from day one.

04 — Audit both the bridge and the new deployment

That's where new bugs are most likely to appear. An Ethereum audit doesn't validate the Rust implementation running on another chain.

05 — Decide how upgrades will work before writing the proxy

Who can approve and deploy changes is a governance decision, not just a technical one. Set the rules early to avoid problems later.
