Reclaim SDKs make it simple to bring user activity, reputation, and identity from external websites into your app.

Welcome to Reclaim Protocol

Reclaim Protocol is a cryptographic system that enables users to prove facts about their activity, reputation and identity that is available present on other apps and websites - but not easily ingestible on your own app. Think of it as a cryptographic notary for the internet - proving what's true on platforms that you don't control. Even when the said platform doesn't have APIs.

Reclaim Protocol has the best in class coverage of data sources (2500+) and best coverage of platforms. So no matter what data point you need, no matter on what platform your app is built - you will have a first class integration experience.

zkProofs

The artifact that is generated via Reclaim Protocol is a zkProof. This zkProof, or more generally just proof, is an encapsulation of :

Data that has been extracted from a webpage a user logged in into
The webpage the user actually logged in into
A cryptographic proof that both of the above are true

This proof is the centerpiece of Reclaim Protocol, and is what should give you confidence that users are not cheating the system - and proving things about themselves which is simply not true.

Use Cases

Reclaim Protocol enables various applications, including:

Education Verification - if you want to verify where and what the student is studying. Useful for marketing campaigns and background verifications.
Employment Verification - If you need to make sure the user works where they claim to work. Useful for lending and hiring.
Financial Background - if you need to verify financial background like credit score, accredited investor status etc. Particularly useful in lending and credit.
Shopping History - if you need to give deals and discounts based on users' loyalty to certain brands
... and many more!

Real world example

Imagine you want to verify if a user is a student at a particular university to give a student discount, how would you do it?

Traditional way

Ask user to upload their transcripts PDF, given that most universities don't have APIs.
Verify the transcripts either Manually or using an AI
Give them the discount if they are a student

Issues with the traditional way

If you are verifying manually, well ... it will take time and resources to actually verify
You are at the mercy of the user to upload authentic PDFs and not morphed ones

Reclaim Protocol way

Ask the user to login into their university student portal
Reclaim Protocol will extract the required information that will indicate that the user is a student, after they have logged in
Reclaim Protocol will generate a cryptographic proof that the information is accurate and has not been tampered with, solving the PDF morphing problem
