Our software is largely based on Open-Transactions, a comprehensive off-blockchain framework for specifying custom electronic financial instruments secured with cryptographic proofs. This dramatically enhances the utility of any cryptocurrency we integrate with and fundamentally eliminates the single point of failure of financial services by divorcing both asset issuance and custody from transaction processing.

For the first time ever, Open-Transactions makes possible fast, secure, and private payments that give users the functionality of financial services while retaining exclusive control over their own accounts. It was originated by our co-founder Chris Odom as an open-source project and is being regularly extended by our expert team of engineers.

Currency Agnostic

Stash's platform is not limited to Bitcoin or similar blockchains. Using our tools, we'll provide users the freedom to issue digital assets directly on-chain as redeemable colored coins.

See our developers section below for more technical information.

Payment Addresses

Our payment address innovation gives users a single, re-usable address for payments and messaging that prevents blockchain observers from viewing transaction history. However, the parties themselves are still able to view the entire history between them. Plus users can refund payments without the hassle of requesting the creation and transmission of a new wallet address (as is the case with Bitcoin today).

Stash’s payment addresses are much more analogous to typical email addresses in terms of functionality (static, bi-directional, and re-usable). This basic functionality is easy to take for granted, but is sorely needed in Bitcoin today. This technology also forms the basis for Stash's decentralized identity platform and private end-to-end communications.

We believe in the benefits of open-source technology and working within a broader community. The following technical resources are available to developers interested in learning more about the innovations we're building upon.
