Secure transaction infrastructure for high-value real estate.
TERRE™ is not a fraud detection tool bolted onto existing software. It is a permissioned transaction environment where identity verification, secure communications, transaction permissions, audit visibility, and financial coordination operate together within a unified security framework.
Five capabilities, one secure framework.
Every transaction runs through the same trust layer — no gaps between identity, communication, money, and audit.
Identity verification
Only verified parties — buyers, sellers, agents, lenders, title — can join a transaction. Cryptographic identity validation closes the door fraudsters rely on.
Secure communications
Encrypted, party-verified channels replace email threads that get spoofed, hijacked, or impersonated.
Transaction permissions
Role-based, policy-driven permissions decide who can act on a transaction, when, and within what limits.
Immutable audit visibility
Every action is recorded on FileChain's permissioned ledger — tamper-evident and admissible for compliance, audit, and insurance.
Financial coordination
Encrypted wire instructions and verified payee routing remove the moment fraudsters exploit — the second money moves.
Cryptographic agility
Designed to evolve with the cryptographic landscape — including post-quantum readiness — so today's protection is durable tomorrow.
Built on FileChain's enterprise ledger.
TERRE's architecture is strengthened by a deep collaboration with FileChain — a company that has spent years developing enterprise-grade permissioned ledger technology for digital trust and immutable records.
Rather than building every foundational ledger component from the ground up, TERRE™ leverages proven distributed ledger infrastructure and focuses its engineering effort on what differentiates the platform: transaction governance, identity verification, AI-control frameworks, workflow orchestration, and real estate-specific security requirements.
The result is a powerful foundation capable of supporting secure real estate transactions today while positioning the platform to address future enterprise requirements: AI-assisted transactions, advanced cybersecurity threats, distributed ownership systems, and increasingly digital financial ecosystems.

Sylvain Vittecoq
CTO & Partner, TERRE™ · Founder & CEO, FileChain
Sylvain is integral to the security of TERRE™. As founder & CEO of FileChain and TERRE's CTO & partner, he leads the cryptographic, ledger, and infrastructure work that underpins every transaction on the platform. His background — a Master in Computer Science and a Master Research in Artificial Intelligence, with years of senior engineering leadership — anchors TERRE's security posture in proven, enterprise-grade infrastructure rather than untested code.
Through this collaboration, TERRE inherits an architectural foundation already aligned with the future direction of secure digital transactions, distributed verification systems, and evolving global compliance expectations.
Not a tool. A trust infrastructure company.
FileChain's international positioning and enterprise-focused ledger development further strengthen TERRE's long-term scalability and strategic credibility.
A unified trust layer that protects identity, communication, money movement, and audit from end to end.
Policy-controlled AI participation with cryptographic accountability for every automated action.
A platform aligned with distributed verification systems, digital ownership, and evolving global compliance.
