# Glossary

> Definitions for Tulip model markets, inference, and settlement.

**Canonical market**\
The single Tulip credit and credit/USDG pool bound to one ModelID.

**Credit**\
The fixed-supply ERC-20 used for market trading and inference settlement for one model.

**Curve preset**\
An approved set of launch supply, starting price, price range, tick spacing, and LP fee distribution parameters.

**Gateway**\
The metered proxy that verifies providers, selects offers, routes inference, reserves credits, and signs usage receipts.

**Inference permit**\
A bounded, model-specific escrow deposit used to pay for inference.

**LP fee**\
The native Uniswap v4 fee applied to a pool swap. It is separate from inference settlement fees.

**Market creator**\
The address recorded when the canonical model market launches. It controls metadata and may schedule pool-fee changes within bounds; changes activate only after the one-hour safety delay.

**ModelID**\
In version 1, the deterministic hash of the Hugging Face repository, commit SHA, task, identity namespace, and schema version.

**Pinned revision**\
In version 1, the exact 40-character Hugging Face Git commit SHA registered by a model market.

**Provider offer**\
An on-chain operator, payout address, endpoint commitments, status, and tariff for serving one model.

**Tariff**\
A versioned provider price schedule for input tokens, output tokens, minimum charge, and endpoint wake-up.

**Usage receipt**\
An EIP-712 Gateway-signed record that binds a metered request to its permit, model, offer, tariff, usage, and timing.

**USDG**\
The quote asset paired with every Tulip model credit market.
