Tradewind Markets was founded in 2016 by a team with expertise in blockchain, electronic trading, and precious metals investment management. Their goal is to create the most secure, efficient, and streamlined platform for trading digitized precious metals. 
Tradewind Markets' Vaultchain platform is a cryptographically secure blockchain distributed ledger technology developed by R3 called Corda. Regulated dealers and institutions can trade, settle and manage the ownership of physical gold and silver and it's all moderated by detailed legal and operating agreements. All precious metals stored securely in the vault of the Royal Canadian Mint.
