See [Anchor vaults](/protocol/anchor-vaults.md). | | **Attestation** | An Ethereum Attestation Service record linking a wallet to a role (trader, LP, maker) after verification has been completed away from the chain. Nothing personal is stored in it. See [Eligibility registry](/architecture/eligibility.md). | | **Band** | The outer limit, measured from the oracle mid, inside which a fill has to land. Cross it and the transaction reverts. | | **Clip** | A ceiling on how much a single swap may take from a vault. Anything larger gets quoted through RFQ instead. | | **Data Feeds** | Chainlink's push-based on-chain price service; its 24/5 equity feeds carry Stock Token pricing through the week. | | **Data Streams** | Chainlink's pull-based low-latency service (v11 RWA schema). Reports include a `marketStatus` field, which is what session classification reads. | | **ERC-8056 multiplier** | What `uiMultiplier()` returns on a Stock Token: underlying shares held per token. Dividends and splits are expressed by moving it, and Chainlink prices already account for it. | | **Execution quality** | How far a fill landed from the oracle mid at inclusion, in basis points, with the sign kept. Reported per fill. See [Execution quality](/transparency/execution-quality.md). | | **Half-spread** | The distance from the mid out to one side of the quote. Icaria's parameters are all written as half-spreads in basis points. | | **Inventory skew** | How far a vault's holdings have wandered from the mix it targets. The skew tilts quoting so that flow which corrects the mix gets the better price. | | **Maker** | A market maker holding an attestation, who signs RFQ quotes off-chain and whose fills settle atomically on-chain. | | **Mid** | The guarded oracle price for an asset as `OracleRouter` reports it. No quote exists without one. | | **Quote asset** | USDG: what every market is priced in, and the denomination of every fee. | | **Regime** | Whichever of `OPEN`, `EXTENDED`, `CLOSED` or `HALTED` a market currently occupies, which fixes its spread multiplier and its clip. See [Trading regimes](/protocol/trading-regimes.md). | | **RFQ** | Request for quote: EIP-712 messages signed by makers, alive for a handful of seconds, settled atomically by whoever takes them. See [RFQ settlement](/protocol/rfq.md). | | **Router** | `SwapRouter`, the single door in: it verifies eligibility, weighs the vault price against the RFQ price, and settles the winner. | | **Session** | Whether the underlying market is in regular hours, extended hours or closed, as reported by the oracle. Regimes are derived from this. | | **Stock Token** | An equity tokenized by Robinhood Assets (Jersey) Ltd: an ERC-20 debt security with 1:1 backing in shares held under US custody. See [Stock Tokens](/assets/stock-tokens.md). | | **Tier** | Which listing class (A, B or C) an asset falls into, which in turn fixes its base spread, clip, band and caps. See [Listing framework](/assets/listing-framework.md). | | **USDG** | Paxos Global Dollar, a MiCA-regulated stablecoin issued natively on Robinhood Chain. See [Quote asset: USDG](/assets/usdg.md). | | **Vault share** | What a depositing LP receives, on ERC-4626-style accounting: a proportional claim over the vault's inventory together with the spread it has earned. | --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.useicaria.xyz/introduction/glossary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
