DeFi Swap Interface

Summary: an independent Web3 interface project focused on making token swap states easier to understand before, during, and after a transaction.

Why I built it

DeFi interfaces often fail at the moments where clarity matters most: wallet connection, network mismatch, approval state, transaction submission, and confirmation. I built this as a focused interface experiment around those states.

What it does

The interface models a swap flow with wallet connection states, token selection, estimated output, approval requirements, transaction review, and confirmation feedback.

Tech stack

React, TypeScript, Web3 tooling, and DeFi interface patterns around wallet-connected flows.

Key engineering decisions

I treated the transaction as a state machine instead of a single submit action. That made it easier to represent the difference between “needs wallet”, “wrong network”, “needs approval”, “ready”, “submitted”, “confirmed”, and “failed”.

Problems I ran into

The biggest product issue was explaining risk without overwhelming the screen. DeFi flows need direct language and clear warnings, but the interface still has to stay scannable.

What I learned

Wallet-connected interfaces need excellent empty, waiting, and error states. The happy path is only a small part of the user experience.

What I would improve next

I would add better simulation data, stronger slippage explanations, and more complete transaction history.
