Overview
The client wanted customers to buy, sell and hold gold as digital tokens, with the speed and convenience of a modern trading app and the controls of a regulated financial business.
Voxen built a hybrid exchange: the front end works like the trading apps customers already know, while a blockchain does the settlement behind the scenes.
The challenge
- Familiar, not experimental. Customers expected the experience of a mainstream exchange, not a crypto tool.
- Fast, accurate settlement. Every trade had to settle quickly and reconcile exactly.
- Treasury security. The funds backing the platform needed shared control, so no single person could move them.
What Voxen built
A mainstream exchange experience.
Customers sign up, verify their identity, fund their account and trade through flows modelled on leading exchanges: a market view with live prices and charts, buy and sell with market and limit orders, a one-step convert screen, and a wallet showing holdings, deposits, withdrawals and history.
Blockchain as the settlement engine.
Trades are matched in the exchange and settled on Stellar, which acts as a fast internal settlement layer. Every balance change has an on-chain record, so the books reconcile against the ledger.
Multi-signature treasury.
Treasury funds are held in Gnosis Safe wallets that require several authorised signers to approve any movement.
Operations and controls.
The business manages users, verification, limits and treasury movements from an administration panel.
Engineering approach
Matching, settlement and treasury are separate services with clear boundaries, so a problem in one cannot corrupt another. Settlement is idempotent: a trade that is retried never settles twice.
Outcome
Customers trade tokenized gold through a conventional interface, with settlement handled on-chain behind the scenes and treasury funds under shared control.
What it makes possible
Other tokenized commodities can be listed on the same exchange, settlement and treasury foundation.
