Real Estate Transactions
Verifiable proof for property transactions
The Challenge
Traditional approaches leave gaps in verification and trust
Property condition disputes after closing
Document authenticity in transactions
Escrow and closing documentation
Proof of inspection findings
How CertNode Solves It
Cryptographic proof for every use case
Property Condition
Timestamped photos and videos of property condition at key dates
POST /api/v1/real-estate/condition
Closing Documents
Verified signatures on closing documents with timestamps
POST /api/v1/real-estate/closing
Inspection Reports
Immutable inspection reports with photo evidence
POST /api/v1/real-estate/inspection
Title Documentation
Chain of title verification with cryptographic proofs
POST /api/v1/real-estate/title
How It Works
Submit Your Data
Use our API or dashboard to submit your data. We compute a cryptographic hash (SHA-256) that uniquely identifies your content without storing the actual data.
Get Cryptographic Proof
We create a multi-layer proof with ES256 signature, RFC 3161 legal timestamp, and Bitcoin blockchain anchor. All in under 1 second.
Verify Anytime
Get a public verification URL anyone can check. Embed badges in your systems. Export independently verifiable evidence packages when needed.
Simple API Integration
Add cryptographic proof to your real estate transactions workflow in minutes
import { CertNode } from '@certnode/sdk'
const certnode = new CertNode({ apiKey: 'cn_...' })
// Create a verified proof
const proof = await certnode.realestate.create({
data: yourData,
metadata: {
type: 'property_condition',
description: 'Your description here'
}
})
console.log(proof.id) // 'prf_abc123'
console.log(proof.verifyUrl) // 'https://certnode.io/verify/prf_abc123'
console.log(proof.rfc3161) // RFC3161 timestamp token
console.log(proof.bitcoin) // Bitcoin block anchorSecure Real Estate Transactions
