Buy and sell digital securities directly from your smartphone.

Digital securities exchange software

Experience the benefits of a marketplace powered by Open Order Book.

Fiat On-Ramp & Off-Ramp

Trading-pairs are quoted, traded and immediately settled exclusively against the exchanges’ deposits of fiat currency, eliminating exposure to cryptocurrency price volatility.

Full Transparency

Offers to buy and sell shares are displayed in real-time on the Ethereum public blockchain, unlike a traditional order book which only displays volumes provided by market makers.

Hack Safeguards

Traders alone hold their private key and all trades are cryptographically signed, adding increased investor protection from dangerous hacks.

Order Driven Marketplaces

Designed to look and feel like a traditional public marketplace with trades conducted on a best bid and offer basis, not just wallet-to-wallet matching.

Cryptographically Secure Trading

All transactions are cryptographically secure with timestamped transaction records stored on the Ethereum public blockchain.
