Privy

Privy builds simple, powerful APIs to manage user data so you can integrate user data into your product easily. Privy helps you bridge the gap between users’ on-chain activity and their off-chain data so you can build delightful experiences without putting your users or at risk. With privy.put() and privy.get(), encrypt user data directly from your front-end, and privately associate data to on-chain addresses. This enables you to:

Text or email users without handling their personal information directly; Take on financial and compliance data without storing it on your stack; Surface a unified UI across wallets and across chains without doxxing your users.

This is just the beginning. The next generation of data tooling should keep users in the loop and in control of their data across the web. As web3 matures, we see an opportunity to reinvent the data paradigms that have failed us over the last 30 years and give users back control over their data online.
