What is StellarProof

StellarProof is the identity layer for Stellar. Verify once using your national ID and Get a credential locked to your wallet. Use it at every anchor instantly, with one tap. No uploading the same passport again. No waiting. No five different apps storing copies of your face.

SDF wrote this goal into SEP-12 in 2018:
"Allow a customer to enter their KYC information once and use it across many services without re-entering manually."

That was the plan. Nobody built the infrastructure. StellarProof is that infrastructure.

The Problem

Stellar has 100+ anchors across countries. Every single one runs its own KYC stack independently - SumSub here, Onfido there, Veriff somewhere else. A user who wants to use three anchors uploads the same passport three times, waits three times, and each anchor pays $1-3 in verification costs three times.

60–80% of users abandon KYC before completing it, Not because they don't want to use the product Because they've done it before and don't want to do it again.

Without StellarProof:
  User → Coins.ph   → Upload passport, ID, selfie. Wait 2 days. ✓  ($1.35)
  User → Vibrant    → Upload passport, ID, selfie. Wait 2 days. ✓  ($1.35)
  User → Bitso      → Upload passport, ID, selfie. Wait 2 days. ✓  ($1.35)

  Same person. Same passport. Same face.
  3 separate databases holding your documents.

Why Nobody Fixed It

SumSub has "Reusable KYC" but it only works within their own network. If Anchor A uses SumSub and Anchor B uses Onfido, reuse breaks completely. The large KYC companies have no incentive to fix this. Cross-provider reuse destroys their per-verification revenue.

The problem was never technology. It was incentives. StellarProof earns only when credentials are reused — so everything we build is designed to make reuse work as well as possible. Our interests and the ecosystem's are the same.

The Solution

StellarProof sits above every KYC provider as a shared identity layer. Verify once — your identity gets encrypted, locked to your Stellar wallet, and recorded on-chain. Every anchor after that gets a simple yes/no: this person is verified, low risk — no documents, no passport copies, no waiting. One tap. Two seconds. Done.

With StellarProof:
  User → Coins.ph   → Verify once via DigiLocker/PhilSys. Credential encrypted. ✓
  User → Vibrant    → One tap consent. Proof returned in 2 seconds.            ✓  ($0.10)
  User → Bitso      → One tap consent. Proof returned in 2 seconds.            ✓  ($0.10)

  Same person. One verification.
  Zero duplicate databases. Zero re-uploads.

The breach that can't leak what it doesn't have. StellarProof stores only encrypted blobs. The server cannot decrypt them under any circumstance including legal compulsion.
