Case Study: Sling achieves non-custodial wallet recovery with Evervault Enclaves

Sling is an app where people can easily send digital cash globally

sling needed to provide a smooth user experience for its non-custodial wallet but struggled with how to offer a simple recovery mechanism for lost keys without compromising security. The challenge was to avoid storing user wallet keys in plaintext while preventing users from being burdened with complex key backup processes.

Using Evervault Enclaves, Sling implemented a solution where key recovery is handled securely between a user's device and the enclave, ensuring Sling never has access to the keys. This allowed Sling to deploy a secure, non-custodial wallet recovery flow, saving weeks of engineering time that would have been spent building a similar system in-house.
