Tracking Property Sales in Real Time

Sector: Tertiary sector · Industry: Real estate agencies · Organisation: Coadjute, Quealy & Co · Maturity level: Production

Coadjute launched a distributed ledger technology-based property network in the United Kingdom and documented a real property transaction with Quealy & Co. The parties involved were able to exchange status information and approved sales data directly through their existing industry systems in real time. The network is in production and connects brokers, banks and legal service providers without manual intermediate steps.

Documentation status

• Project status: Production (as of 25 August 2026) — A live British network with a documented real property transaction and ongoing industry integration.
• Evidence: Evidence high
• Editorial review: SapientBlock Redaktion, 24 October 2026

Description

Coadjute, in collaboration with the estate agency Quealy & Co, built a platform that digitises information exchange in the property sector. Traditionally, brokers, banks and solicitors work with separate software systems, leading to time-consuming emails and opaque delays. The solution links these existing industry applications directly via a secure DLT network, so that every party can automatically track the current progress of a sale.

The technical foundation of the British network is R3 Corda, an enterprise DLT solution for confidential data processing. The system connects estate agency management programmes, conveyancing solicitors' systems and lending institutions' platforms via secure nodes. As part of a real sale completion, Quealy & Co demonstrated the system's functionality by seamlessly transferring transaction updates and document approvals between the systems. The data is not sent to a central collection point, but synchronised exclusively between the institutions involved in the purchase. Renowned institutions and portals continue to support the project through strategic investments and ongoing system integrations.

Perspectives

B2B — organisations perspective

B2B actors such as estate agencies, law firms and mortgage lenders connect their existing systems directly to the network. This enables automated data exchange across organisational boundaries without having to switch proprietary platforms.

B2C — consumers perspective

End customers benefit indirectly from shorter response times and more reliable information about the progress of their property purchase. However, direct end-customer access is not primarily intended in the current B2B infrastructure approach.

Employees perspective

Employed case handlers and estate agents can see the current processing status of a property transaction directly in their familiar user interface. This eliminates time-consuming telephone status enquiries from the daily workflow.

Benefits

General

• Direct synchronisation of transaction progress across organisational boundaries
• Reduction of manual queries between the organisations involved
• Preserved data sovereignty through exclusive point-to-point transmission

B2B — organisations

• Reduction of administrative media discontinuities between law firms, brokers and banks
• Seamless integration into already established broker and transaction software

Employees

• Relief from repetitive coordination work by email or telephone
• Real-time insight into the processing status of all ongoing cases

Challenges

General

• Dependency on the willingness of heterogeneous software vendors in the property market to connect
• Legal and regulatory requirements when linking financial and land registry data

B2B — organisations

• Effort required for the initial configuration of interfaces in established IT landscapes

Employees

• Need to change established manual communication routines

Technology foundation

The network is based on the enterprise distributed ledger technology R3 Corda, which was specifically developed for regulated industries. Corda enables selective data transmission exclusively between parties involved in a transaction, so that confidential contract data is not disclosed across the entire network.

Implementation examples

Live Transaction Network for the British Property Market

The fragmented communication process between estate agents, buyers, solicitors and banks regularly leads to delays and opaque processes in the United Kingdom.

Coadjute created a DLT network based on R3 Corda and completed a real transaction with Quealy & Co.

In collaboration with the estate agency Quealy & Co, Coadjute completed a real property transaction via the production network. The platform connected the agent's existing software with the systems of the transaction participants involved, so that status and approval data could be exchanged in real time. The architecture does without a central database and instead relies on direct node connections to keep sensitive transaction details confidential.

Elimination of opaque media discontinuities and enabling a synchronous information status across disparate software solutions.
