LETHE

The Veil

Every AI request today leaves a paper trail.

Prompts retained

Providers log every prompt and response by default, indefinitely, for training and “safety.”

Identity linked

API keys and accounts tie every request back to a real identity — no way to ask anonymously.

Trust, not proof

Privacy policies promise good behavior. Nothing lets you verify what actually happened to your data.

LETHE

Ask anything, privately.

The Protocol

How a request runs inside LETHE, unread by anyone.

01

Encrypted request

Your prompt is encrypted client-side and paid for via x402 — no account, no API key tied to your identity.

02

Attested execution

The model runs inside a Trusted Execution Environment; even LETHE's own infrastructure cannot read the prompt or the output.

03

Verifiable deletion

A cryptographic attestation proves the request ran in an isolated enclave and was discarded — not just promised, provable.

See It Run

One request in, one response out, nothing remembered.

One OpenAI-compatible endpoint, callable from cURL, TypeScript, or Python. Encrypted request, attested execution inside a TEE, verifiable deletion — the same flow described in The Protocol, made real in three lines of code.

The Token

Stake $LETHE, earn your share of every call.

Stakers earn protocol revenue. Every call burns supply. The more LETHE is used, the scarcer it gets.

Stake & earn

A share of every call

Stake $LETHE to earn a share of the USDC paid through x402 for every inference call on the network.

Burn on use

Deflationary by design

A portion of $LETHE is burned with every call, permanently shrinking supply as usage grows.

Our Product

Private inference infrastructure for agents and developers.

Cognition

Cognition

Your prompts and completions are never visible outside the enclave running them.

Perception

Perception

No dashboard, no logs, no operator with access to your requests — not even us.

Timing

Timing

Every call is paid and settled in the moment via x402 — nothing left behind after.

Network

Network

Built for agents talking to agents, machine to machine, over the OpenAI API.
