A property doesn't change hands until the chain checks out.

gateRealEstateTransactions forensically seals that a property transaction passes three sequential sub-gates, transparency register down to the natural person, notarial matching of source of funds and escrow account, and EU Taxonomy conformity. Support for notaries and transaction parties, never a replacement for the notarial deed itself.

In one sentence: gateRealEstateTransactions checks a property transaction deterministically against three cascading sub-gates, transparency register, notarial escrow account, ESG taxonomy, and seals the result with a cryptographic signature.

✓ RELEVANT IF...

You process property transactions and need to prove the UBO chain down to the natural person
You need to forensically match source of funds against the notarial escrow account

✕ NOT RELEVANT IF...

You expect a system to itself perform a notarial deed
No property transaction or escrow settlement is involved

// The problem

Obscured ownership structures, unmatched source of funds.

The UBO chain down to the natural person, the match between source of funds and the notarial escrow account, and EU Taxonomy conformity are today usually checked separately. gateRealEstateTransactions brings all three together in a sealed run.

// Architecture

Three sub-gates, cascading.

SUB-GATE 1

Transparency Register

Checks whether the UBO structure is broken down to the last natural person, at a 25% threshold under GwG Sec. 4 and EU Directive 2015/849.

SUB-GATE 2

Notarial Sealing

Checks whether the source of funds matches the escrow settlement on the notarial account, under the Notarial Recording Act and the Anti-Money-Laundering Act.

SUB-GATE 3

ESG / EU Taxonomy

Checks Energy Performance Certificate class, primary energy demand, the Do-No-Significant-Harm principle, and EU Taxonomy alignment under Regulation (EU) 2020/852 and EPBD Directive 2024/1275.

// Clarification

What gateRealEstateTransactions is not.

Not a notarial deed. The gate checks submitted evidence, it does not replace a notary's own recording.
Not a replacement for review by the transparency register itself or an Energy Performance Certificate issuing body.

A property doesn't change hands until the chain checks out.

Obscured ownership structures, unmatched source of funds.

Three sub-gates, cascading.

What gateRealEstateTransactions is not.

For notaries and transaction parties that want to make their deals provable.
