Launching Q1 2027

A verifiable Will lifecycle for Hong Kong

Help ordinary users prepare, manage, and preserve a verifiable record of their Will — with identity checks, execution evidence, and future executor access.

  • ✓ Structured Will-building with controlled clause logic (AI for guidance, not free-form drafting)
  • ✓ iAM Smart verifies testator, witnesses, and authorised executor at key stages
  • ✓ Cryptographic hash on-chain after signing — Will contents and personal data stay off-chain
  • ✓ Read-only executor handover after death and access conditions are met

In development

The digital will lifecycle.

WillsLedger is still being built. Here is how the Hong Kong–focused lifecycle is designed to work when it launches.

Step 01

Guided Will preparation

Walk the testator through appointing executors, naming beneficiaries, the residuary estate, optional gifts or guardianship, and flags that may need professional legal review. AI can assist intake and guidance; the Will wording itself is produced through controlled clause logic — not unrestricted AI drafting.

Who acts
Testator (guided)
AI role
Intake & guidance only
Result
Structured Will draft
Step 02

Paper signing & iAM Smart checks

The Will remains a physically signed paper document and must follow Hong Kong execution requirements. iAM Smart is intended to verify the identities of the testator, witnesses, and authorised executor at the relevant stages — digital checks do not replace legal signing and witnessing.

Who acts
Testator & witnesses
Identity
iAM Smart
Legal form
Signed paper Will
Step 03

Hash, confirmations & audit refs

After signing, WillsLedger can generate a cryptographic hash of the exact Will document and record related witness confirmations, timestamps, version information, and audit references. The Will and personal data stay off-chain; the ledger retains hashes and verification references so integrity can be checked later.

On-chain
Hash & evidence refs
Off-chain
Will & personal data
Result
Integrity checkable
Step 04

Executor handover access

After the testator’s death and satisfaction of the relevant access conditions, an authorised executor can verify their identity and open a limited, read-only record — the Will record, document hash, witness-confirmation trail, and audit information — without claiming the digital record itself creates or validates the Will.

Who acts
Authorised executor
Access
Read-only, conditioned
Result
Verified handover trail

Testators & families

A clearer path to prepare a Will and leave a verifiable integrity record — without putting private Will contents on the blockchain.

Legal professionals

Structured intake and clause-controlled drafting support, plus flags when a matter may need solicitor review under Hong Kong practice.

Executors & institutions

Identity-verified, read-only access to hash, witness trail, and audit references when handover conditions are met.

New

Redefining art authentication and provenance

Bridge the physical and digital worlds of fine art — tamper-proof NFC/RFID tags connect each artwork to an immutable blockchain certificate, so authenticity and ownership history are never in doubt.

  • ✓ NFC/RFID tags bind each physical artwork to an on-chain certificate
  • ✓ Full provenance history — origin, exhibitions, ownership transfers — sealed on-chain
  • ✓ Instant authenticity verification with a single tap or QR scan
  • ✓ Tamper-evident design defeats forgery and altered paperwork

How ArtLedger works

The art provenance lifecycle.

From the studio to the auction floor, every step in an artwork's life becomes a verifiable, tamper-proof record.

Step 01

Tag & register the artwork

A tamper-proof NFC/RFID tag is embedded in or affixed to the physical artwork, and the piece is registered with artist, medium, dimensions, and creation details.

Who acts
Artist or gallery
Hardware
Tamper-proof NFC / RFID
Result
Registered artwork record
Step 02

Generate the blockchain certificate

ArtLedger anchors a certificate of authenticity on-chain, cryptographically linked to the physical tag — an immutable reference that can never be quietly edited or duplicated.

Who acts
ArtLedger platform
Anchored on
Hyperledger Fabric
Result
On-chain certificate
Step 03

Track every custody event

Exhibitions, loans, conservation work, sales, and ownership transfers are each logged as a verifiable on-chain event, building a complete and auditable history.

Who acts
Galleries, owners, custodians
Events logged
Loan, sale, transfer, exhibition
Result
Continuous provenance trail
Step 04

Verify in seconds, trade with confidence

Collectors, galleries, and auction houses tap the NFC tag or scan a QR code to instantly confirm authenticity and review the full provenance history before a sale.

Who acts
Buyers, auction houses, insurers
Check takes
Seconds, no phone calls
Result
Verified authenticity & history

Collectors & buyers

Verify authenticity and full ownership history before purchase — no more relying on paper certificates alone.

Artists & galleries

Register new works at creation and build a verifiable provenance trail from the very first sale onward.

Auction houses & insurers

Instant, tamper-proof provenance checks that reduce forgery risk and streamline due diligence.
