Monopriz is an existing exchange service. The task was to improve how customers select an asset and network, complete the exchange form and return to their account.
I refined PHP templates, CSS and JavaScript around the existing PremiumExchanger engine: form layout, feedback and validation states, account navigation and transaction history.
The work is interface customisation, not a replacement transaction engine. These English presentation screens adapt the original Russian interface.
Selected screens
Asset and network selection — keep sending and receiving choices beside the amount fields.
Customer account — custom forms and visible states connected to the existing exchange engine.
