Glossary

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.
