BlockRiver

Sole product designer since v1. Four years on one product — from a draft demo, through a white-label platform that four licensees launched under their own brands, to an institutional multi-asset OTC settlement desk. The company operates as a Swiss financial intermediary under VQF, an SRO recognised by FINMA.

2022–2026

Four years, different stages

Same product, three brands. Four of those years ran in production under other people’s names — pre-launch applies only to the last one.

2022

WizWiz

A draft demo under Tunex LLC. A universal portfolio block sat inside a currency interface — half the screen reacted to the selected asset, half did not.

2023–2025

Marionette

White-label platform. Four licensees launched it under their own brands, one of them an African crypto exchange.

Four years in production under other names.

2025–2026

BlockRiver

Institutional OTC settlement under its own brand, registered in London in spring 2026.

Own brand, pre-launch.

Auth

Sign-in, account setup, and the states a user can get locked out of.

Wallet

Portfolio and per-asset balances split into two blocks with explicit boundaries — the change this case turns on.

Deposit

Funding an account: asset, network, address and confirmation.

Withdrawal

Sending funds out — the one action on the platform that cannot be undone.

Design System

Tokens and components shared by the web app and mobile — the layer four licensees rebranded the product.
