Hardware-rooted cybersecurity that lets devices, IoT systems and AI agents authenticate, collaborate and transact autonomously, with identities built to withstand quantum computers.

Why today’s infrastructure breaks
Billions of machines are about to act on their own: buying energy, selling data, paying for compute. Existing infrastructure was designed for connected devices. It was never designed for autonomous economic actors that must prove who they are, agree terms and settle value without a human in the loop.
The quantum clock is already running. Data and signatures captured today can be stored and broken once quantum computers mature. Devices shipped now will still be in service then, so their identities need post-quantum protection from day one.
What machines can do with SEALCOIN
Five ways devices and agents already use the same trust infrastructure. In each one, the transaction is only as strong as the identity behind it.
IoT devices and AI agents negotiate, execute and settle service-for-payment exchanges without human intervention.
A drone detects a low battery, finds a certified charging station on the SEALCOIN network, authenticates, pays and recharges.
Trust layerBoth machines prove their identity with certificates held in a secure element before any payment moves.
Homeowners with solar panels sell surplus energy directly to other consumers or devices in real time, acting as independent producers in a decentralised energy market.
Trust layerMeters and inverters sign every reading, so buyers pay only for energy from verified sources.
Agents acting for people or organisations negotiate, decide and transact with other agents and services, within the policy limits their owners set.
Trust layerEach agent carries a verifiable identity and its own non-custodial wallet.
Devices publish verified telemetry and earn tokens for it. In agriculture, energy and logistics, tamper-proof data becomes a tradable asset across borders and connectivity gaps.
Trust layerData is signed with post-quantum cryptography at the source.
Integrated with WISeSat, satellites and ground devices authenticate, exchange data and settle value, even in remote or offline environments.
Trust layerIdentities are verified satellite-to-ground, with no terrestrial network required.
Security stack
SEALCOIN builds trust from the chip up. Every transaction rests on five layers, and post-quantum cryptography protects the identity layer that everything else depends on. Click a layer to see what it does and who provides it.
Machines negotiate, execute and settle service-for-payment exchanges on their own, within the rules their owners set, with QAIT as the settlement token on Hedera.
SEALCOIN transaction engine · Hedera · QAIT
Authenticated machines find trusted services, prices and counterparties through broker nodes, even from behind firewalls and carrier networks.
SEALCOIN broker nodes
Before any exchange, machines prove who they are to each other with their certificates. Unknown or revoked devices are refused automatically.
SEALCOIN platform
Each device and agent receives a certificate-based identity protected with post-quantum cryptography, so identities issued today stay trustworthy through the device’s whole service life.
WISeKey PKI + post-quantum cryptography
Keys are generated and stored inside a secure element at manufacturing. They never leave the chip, so a device cannot be cloned or impersonated in software.
SEALSQ secure hardware
Live from orbit
WISeSat satellites carry WISeKey Group secure hardware into low Earth orbit, extending machine identity and transactions to places terrestrial networks do not reach. Track the constellation live.
Introducing SEALCOIN
SEALCOIN is a hardware-anchored cybersecurity and transaction infrastructure. It lets machines identify themselves securely, discover services, negotiate, execute and settle transactions without human intervention.
It combines a hardware root of trust, PKI, post-quantum cryptography, machine identity, peer-to-peer messaging, broker nodes, a transaction engine and programmable settlement. Instead of building another IoT platform, SEALCOIN provides the trust layer others build on.

Economic layer
QAIT is the native utility and payment token of the SEALCOIN ecosystem. Devices and agents use it to pay for energy, data, compute and connectivity, while it anchors governance and identity through the Proof-of-Security (PoSy) mechanism.
