NVDC — the inference market you can prove.

NVDC (nvdc.ai) is a decentralised, OpenAI-compatible GPU inference marketplace. Buyers call a familiar API at a market price; GPU operators connect hardware and earn USD. Every request runs over an NVIDIA NVTrust-attested channel and settles against dual-signed Ed25519 receipts that either party can verify independently.

Designed, built and operated by ExchangeSpeed Pty Ltd — the only product on this site we publicly attach our name to, because it is ours end-to-end.

A market for inference, with cryptographic proof attached.

NVDC turns a GPU into a verifiable inference node on a decentralised network. Consumers point existing applications at an OpenAI-compatible endpoint and pay per million tokens; miners run the NVDC client on real GPUs (H100, H200, B200, RTX Pro 6000, and others) and earn USD when their hardware answers a request.

The platform is built around NVIDIA NVTrust, a confidential computing framework for GPUs. Every inference is hardware-attested — you can cryptographically prove that a specific model ran on a real, unmodified GPU — and every settlement is a dual-signed Ed25519 receipt that buyer and seller verify independently.

Two sides of one market.

For consumers

Buy inference like an API.

Call an OpenAI-compatible endpoint — any app already wired to OpenAI can switch to NVDC with minimal change.
Requests are routed to the best available GPU on the network at a market price.
Pay in USD per million tokens processed; settle against verifiable receipts.

For miners

Sell GPU time, earn USD.

Download the NVDC client, connect a supported GPU, and load a model.
Set a minimum price; when buyers route work to your GPU, you earn.
Payouts are handled via Stripe direct to your bank account.

Verifiability, end to end.

Most inference today is a black box: you call an API, you trust that the model you paid for is the model that ran. NVDC removes the trust by turning the proof into a hardware artefact. NVTrust attestations bind a request to a specific GPU; Ed25519 dual-signed receipts bind the settlement to both buyer and seller. Either side — and a third party — can verify both, after the fact, without asking permission.

OpenAI-compatible API

Drop-in endpoint for any application already speaking the OpenAI Chat Completions protocol.

NVTrust attestation

Hardware-rooted proof that a specific model ran on a real, unmodified NVIDIA GPU.

Dual-signed receipts

Every settlement is an Ed25519 receipt signed by both parties — independently verifiable, indefinitely.

USD settlement

Stripe-backed on- and off-ramp; miners are paid out to their bank, buyers spend per million tokens.

Relay market

A separate board for non-time-sensitive jobs where any agent can answer and validators settle disputes.

MCP endpoint

Model Context Protocol surface for AI agent integrations — Cursor, Claude Code, and similar clients.

ExchangeSpeed is a deep-technology studio in Australia. We design and operate frontier compute, settlement and intelligence systems — usually under discretion, on behalf of clients. NVDC is the exception: a product we built and run as principal, in public, and the only product we attach our own name to on this site.

If you are operating in the same neighbourhood — verifiable compute, decentralised inference, programmable settlement, sovereign AI infrastructure — and want to build something adjacent, our brief inbox is open.
