Connections businesses
actually trust.

Liên Kết — Vietnamese for "to link" — is the connection layer for cross-border B2B. Verified identities, signed contracts, wired-in integrations. The handshake, made unforgeable.

Buyer in Hà Nội

verified · KYB · DID

Supplier in Bangkok

verified · contract signed

A trust fabric for the way ASEAN actually does business.

Cross-border deals collapse on the soft parts: who is this entity, is the signature real, can I plug into their system, will the goods clear customs, will I get paid? Liên Kết consolidates those answers into a single connection — issued once, valid everywhere we reach.

Verified identity

KYB-grade entity verification anchored to national registries. One DID per business — portable, revocable, auditable.

Signed agreements

eIDAS- and Vietnam-eContract-compatible signing. Cryptographic provenance for every clause and amendment.

Wired integrations

ERPs, customs gateways, banking rails and logistics APIs — pre-mapped, pre-authenticated, ready to call.

The trust layer is yours.

Identity keys live with the business. Liên Kết never custodies the private material — we issue the introduction, you sign the deal. Sovereign by design, useful by default.

✓ Decentralised identifiers (DID) per business entity
✓ Verifiable credentials for licences, certificates, ratings
✓ No central honeypot — keys held by the issuer
✓ Audit trail you can present in court, not just to a console
