We never store your documents on-chain. Only the cryptographic hash is anchored publicly. Your sensitive information stays private.
Instant Verification
Verify any payment receipt in seconds. Share your hash with banks, courts, or anyone who needs proof — they can verify independently.
EMI Reminders
Never miss an EMI. Get smart reminders before your due date and track upcoming payments across all your active loans.
Audit Trail
Every action in the system is logged. Complete audit history of all your loan activity with timestamps and context.
Process
How DebtProof Works
From loan to blockchain proof in four simple steps.
01
Add Your Loan
Enter your loan details — lender, principal, interest rate, EMI amount, and start date. DebtProof organizes everything in one place.
02
Record Repayments
Log each payment with the amount, date, payment method, and bank reference number. Upload your receipt PDF or image.
03
Generate Cryptographic Hash
DebtProof computes the SHA-256 hash of your receipt document. This fingerprint uniquely identifies your document.
04
Anchor on Blockchain
The hash is stored on Monad Blockchain — immutable, public, and permanent. Your payment proof exists forever.
Security
Enterprise-Grade Security
DebtProof is designed with a security-first mindset. Your financial data deserves the highest level of protection.
SHA-256 Hashing
Industry-standard cryptographic hash function used by Bitcoin and the entire web.
JWT Authentication
Stateless, signed tokens for secure API authentication. Automatic rotation and blacklisting.
Zero Knowledge of Sensitive Data
We never read your document contents. Only the hash is computed and stored.
Rate Limiting
All APIs are protected against brute-force attacks with intelligent rate limiting.

// Verify payment receipt
const hash = sha256(receiptFile);
// Check on Monad Blockchain
const result = await verifyHash({
hash: hash,
network: "monad-testnet"
});
// ✅ Verified
console.log(result);
