One complete view of the transaction

One deal with many parties, all connected

A deal is more than a transfer.

There are contracts to sign, conditions to meet, payments to confirm and several people following along.

On Lusonexa, each participant sees, according to their permissions:

  1. What has happened
  2. What is pending
  3. What comes next

Lusonexa does not just show where the money went. It shows where the deal stands and what is needed to complete it.

  1. Less coordination work

    Documents, signatures and payments organised around the same transaction.

  2. Greater transparency

    Each stakeholder follows the information relevant to their role.

  3. More control

    See what is complete, what is outstanding and who needs to act next.

Where there is financing, Lusonexa can help keep the related documents and payments within the same transaction, making it easier for authorised stakeholders to follow.

From record to confirmation

Track every payment through to completion, from the deal record to confirmation.

  1. Step 1

    Record or integrate the deal

    Contract, asset, amounts, source and destination currency in one record.

  2. Step 2

    Set participants and milestones

    Deposit, down payment, instalments, balance and recipients.

  3. Step 3

    Pay or receive

    Review the quote and fees, confirm and make the payment with Lusonexa.

  4. Step 4

    Track every payment

    Follow the conversion and payment as they happen, through to confirmation.

  5. Step 5

    Confirm and reconcile

    Every amount is linked to the correct milestone.

  6. Step 6

    Complete the deal

    Move to delivery or completion with a confirmed status.

What was agreed is on record. So is what was paid

Sign documents electronically, track payments and keep a verifiable history of every transaction.

With blockchain technology, you can confirm whether a document matches the version originally registered, even long after.

Blockchain at Lusonexa

What blockchain adds to this process

When the contract is signed, Lusonexa records a unique digital fingerprint of the document on a blockchain. Later, any party can confirm that the file is exactly the one that was signed and linked to the payments.

  • Verifiable integrity

    Any change to the file, however small, no longer matches the recorded fingerprint.

  • Independent verification

    The record sits on a distributed network and does not depend only on Lusonexa's systems or on any single party.

  • Date and time of record

    It shows when the final version was attached to the deal, without relying on email threads or memory.

  • Confidential content

    Only the digital reference goes on the blockchain. The contract and personal data are not published.
