Cardano Side Chain Bridge

A cross-chain bridge for moving tokens between the Cardano main chain and a sidechain. As the only designer on Input Output's Sidechains team, I turned an intimidating multi-wallet, multi-chain operation into one guided flow.

Cardano Side Chain Bridge
Situation

A graphical front door to moving MFT tokens between the Cardano main chain and a Cardano sidechain, built inside Input Output's Sidechains department.

Audience

Two specific people: someone comfortable with crypto but not the command line, and a developer who could bridge by hand but wanted the time back.

What made it hard

Two wallets on two networks, a testnet, a faucet, collateral, a smart contract and two-sided signing, then trusting a transfer you could not watch settle.

Honest note

The visual language was inherited from the client's existing brand. My work here was the information architecture, the flows and the interaction model behind every screen.

Process

Mapped the full set of states a cross-chain transfer can reach, then collapsed them into one legible four-step rail with the real mechanics wrapped in plain language.

Outcome

A non-coder could finish a transfer and a developer could fly through one. The internal engineering team used it as day-to-day tooling, and the groundwork fed into the parallel Lace wallet and Midnight products that ship publicly today.
