Token4Token is a decentralized marketplace for AI inference that operates without a central operator or API key requirements. It enables clients to access AI model inference services on a pay-per-token basis, with all transactions and coordination managed on-chain. The platform is built on Gnosis Chain for payment escrow and uses Ethereum Swarm for routing encrypted prompts and responses, ensuring that every byte of communication is handled through decentralized infrastructure. Payments are made in xBZZ tokens, and prices are set per million tokens for each model offered by providers.
The system is designed for two main user groups: clients seeking to run inference on AI models and providers who have GPUs and compatible backends. cpp. They register on-chain, stake xBZZ tokens, and publish their model offerings and prices. Providers earn revenue per token served and are subject to slashing of their stake in the event of repeated faults or missed deadlines. Clients interact with the gateway container, which exposes a local OpenAI-compatible endpoint. The gateway selects a provider from the live on-chain directory, escrows the payment, and sends the encrypted prompt over Swarm. If the provider delivers the inference result within the deadline, they claim the payment; otherwise, the client receives a refund.
Token4Token emphasizes a trustless, permissionless approach to AI inference. There is no central marketplace operator, no rate limits, and no required API keys. All reputation, selection, payment, and liveness checks are handled on-chain. The platform supports OpenAI-compatible /v1/chat/completions endpoints, making integration with existing tools straightforward. Onboarding for both clients and providers is facilitated through containers that include wallet creation and Swarm postage stamp binding. The live provider directory is maintained on-chain and displays only active providers with current offerings, sorted by price. This structure allows anyone with suitable hardware to participate as a provider, while clients can select services based on price and availability, all within a decentralized, censorship-resistant environment.
In the AI & ML space, Token4Token takes a focused approach. It focuses on providing decentralized, censorship-resistant AI inference without centralized API keys or middlemen. It is built as an open-source project for AI developers and model providers. Token4Token is a paid product. It runs on the web and API.
Token4Token first shipped in 2026. Development happens publicly on GitHub with 102 commits in the last 90 days. PulseGate's similarity index finds few close equivalents — Token4Token occupies a relatively distinct niche. Key capabilities include OpenAI-compatible API, decentralized payments, and provider staking. It exposes integrations via a public API.
