> The words these docs use, and what each one means here.

| Term                    | Meaning                                                                                                                                                |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Taker**               | Anyone requesting and executing a swap.                                                                                                                |
| **Resolver**            | An operator running a node that signs binding offers from inventory it controls.                                                                       |
| **Node**                | The resolver's program: one binary, `panofx-node`, run from the app or the command line.                                                               |
| **RFQ**                 | A request for quote, broadcast to resolvers for a specific size.                                                                                       |
| **Offer**               | A resolver's signed Permit2 limit order (EVM) or maker-signed settlement transaction (Solana). Binding until its deadline.                             |
| **Quote**               | The relay's firm answer to a taker: the winning offer priced with the fee and gas lines, valid for 20 seconds.                                         |
| **Relay**               | The Panofx service that runs RFQs, validates and ranks offers, and applies abuse controls.                                                             |
| **Keeper**              | The relay's submitter. It pays gas, is repaid inside the transaction, and holds gas money only.                                                        |
| **Sponsored execution** | The default: the taker signs a `TakerAuth`, the keeper submits and pays gas, and is repaid from the taker up to the signed cap.                        |
| **Self-execution**      | The fallback: the taker submits the same settlement and pays their own gas.                                                                            |
| **TakerAuth**           | The taker's EIP-712 authorization: exact offers, recipient, minimum proceeds, maximum gas fee, fee token, deadline.                                    |
| **LimitAuth**           | The same shape without the offers: authorizes whichever offers deliver the minimum in the named token before the deadline. The basis of a limit order. |
| **Fee token**           | The token, one of the corridor's pair, in which both the protocol fee and the gas fee are charged. On Solana, the fee mint.                            |
| **Corridor**            | A pair on a chain, such as cNGN/USDC on Base Sepolia. One entry quotes both directions.                                                                |
| **Oracle band**         | The relay's advisory reference rate: a median of public NGN/USD sources, published to nodes every 10 seconds. It flags outliers and never sets prices. |
| **Registration**        | A wallet signature plus a name, region and alert email. The only step between a node and its first RFQ.                                                |
| **Reliability score**   | A rolling measure of a resolver's response, validity and settlement rates over 7 days. Public; ranks resolvers when prices tie.                        |
| **Demotion**            | Automatic removal from RFQ fan-out for one hour when a resolver's reverts or score cross a threshold.                                                  |
| **Liquidity steering**  | Preferred or restricted resolver wallet lists on a quote; the compliance primitive for integrators.                                                    |
| **Signer backend**      | The module that produces a node's signatures: keyfile, Turnkey or MPCVault.                                                                            |
| **Remote console**      | An end-to-end encrypted channel through the relay that lets a paired browser drive a node running somewhere else.                                      |
| **Permit2**             | Uniswap's canonical signature-transfer contract, at the same address on every EVM chain.                                                               |
| **Reactor**             | UniswapX's `LimitOrderReactor`, vendored at v2.1.0, which settles every EVM fill.                                                                      |
| **PanofxValidation**    | The contract every EVM offer names. Admits only the executor as filler, and carries the network pause.                                                 |
| **PanofxFeeController** | Returns the protocol fee output: at most 5 bps of the fee token to the treasury.                                                                       |
| **PanofxExecutor**      | The filler for every EVM fill. Pulls the taker's leg inside the reactor's callback, pays proceeds and gas, and holds nothing.                          |
| **Order engine**        | The vendored Solana program whose single `fill` instruction settles both legs once maker and taker have both signed.                                   |
| **Base units**          | Integer token amounts before the decimal point is applied. Every amount in the API is a base-unit decimal string.                                      |
