The challenge
Wallet mistakes cannot be undone, and an extension squeezes onboarding, seed phrases, balances, transfers, history and custom RPC setup into a few hundred pixels.
What we built
- Sequential send flow with validation at each step, so a transfer is never completed by momentum.
- Custom RPC and network management for advanced users without cluttering the default view.
- Saved contacts to remove the most common source of loss: pasting the wrong address.
Outcome
Built from scratchState driven UI for every transaction statusDelivered at XORD
