Blockchain-based Real Estate Safe Transaction SDK
We’ve developed an SDK (Software Development Kit) that can be conveniently integrated into your real estate app, to effectively prevent any real estate scams.
01
Check landlord information in real-time
Before signing any paperwork, you can easily check all relevant information about the landlord by scanning the landlord’s QR code.
02
Register & Update the property lease status
Upon completing the lease agreement, you can record the current lease status of the property on the blockchain network, which can prevent any future real estate scams.
SDK Screen
Verify the landlord's information
01
Landlord’s Real Estate App Screen
When tenants/applicants request for landlord’s information, the landlord can press the ‘Share Information’ button on his/her Real Estate App.
02
Landlord’s QR Code
When the landlord presses ‘Share Information’ button, a QR code appears. This QR code allows any information to be shared securely and privately.
03
Applicant Scans
Landlord’s QR Code
By scanning the landlord’s QR code, applicants can view and verify the information shared by the landlord.

Verify Landlord’s Information in Real-time
Applicants can decide to sign the lease (or not) after verifying the landlord’s information.

Registering/Updating Property Lease Status
Right after signing the lease, update the property’s lease status in real-time on the blockchain network to prevent any future real estate scams.

Property Details Screen
After signing the lease, the tenant presses the ‘Register Lease Info’ button on the ‘Property Details’ screen, to update the property’s lease status.
* Landlord or Agent can update the lease status instead

Register Lease Info Screen
The property details are automatically filled in. The tenant can record the landlord’s information and the lease terms.
03
Request Landlord’s Signature
After completing the lease registration form, the tenant requests (via QR code) the landlord to confirm and sign the form.
04
Landlord Scans Tenant’s QR Code
The landlord scans the tenant’s QR code to receive the completed lease registration form for review.
05
Review Lease Info & Sign
When the landlord signs the lease registration form, the property’s updated lease status is registered on the blockchain network.
* This process can replace Lease Reporting
