What is the Bounty?

$25,000 USD to create a secure and encrypted token portfolio application on top of Blockstack.


We've seen overwhelming inbound requests for a secure and private token portfolio manager, built on Blockstack, that can aid in investment decisions and monitor active positions. A broad portfolio management platform is also one possible first step towards more complex, decentralized financial tools for both personal and professional finance.
