EarnProof currently implements minimum-income proof creation end to end in the backend and frontend.

​
Minimum Income Proof

Proves that total or average income met a threshold during a selected period. Example:
The subject received at least 1,000 USDC between January and March 2026.

​
Frontend Flow

The frontend exposes proof creation at:
The page lets a worker:
  • connect Freighter,
  • request and sign a wallet challenge,
  • sync Stellar testnet payments,
  • classify payments as income or non-income,
  • select eligible income payments,
  • enter a threshold and date window,
  • create a signed minimum-income credential,
  • open the public verification page for the resulting proof ID.

​
API Flow

Example request:
The backend checks that selected payments belong to the authenticated wallet, are marked as income, are eligible, use the requested asset, and fall inside the requested date window.

​
Response

The response includes:
  • proofId,
  • proof status,
  • signed credential payload,
  • public verification URL,
  • contract anchoring result,
  • disclosed claim summary,
  • expiration timestamp.
The signed credential hides raw payment IDs, full wallet history, and individual source transaction details from public verifiers.

​
Planned Proof Types

Recurring-income proofs and payment-receipt proofs are still planned. They should reuse the same wallet authentication, payment indexing, canonical credential signing, and public verification path.
