# SQRL Markets

SQRL Markets is cross-border payments and FX for banks on SQRL, and the desk that banks, liquidity providers, brokers and fintechs run them from. You run a SQRL Lightning hub, fund corridors with tokenised deposit and stablecoin liquidity in channels under your own keys, set your FX rate, and settle each payment atomically, converted in flight.

## Who this section is for

* **Banks** pay out abroad at their own FX rate, under their own whitelist and limits. Start with [How SQRL Markets works](/markets/how-it-works) and [Payments](/markets/payments).
* **Liquidity providers** fund corridors, set their charge and daily cap, and earn the spread on each payment. Start with [Liquidity and Rails](/markets/liquidity) and [Pricing](/markets/fx/pricing).
* **Brokers and fintechs** run FX and cross-border payouts from a hub they run themselves or one SQRL hosts for them. Start with [Connecting your hub](/markets/getting-started/connecting-your-hub).

Your team can try the desk end to end on the public testnet hub, SQRL's sandbox, before any client funds move. See [Connecting your hub](/markets/getting-started/connecting-your-hub#choosing-a-hub).

## What you do in SQRL Markets

* **Pay out across currencies.** A shopper or sender pays in one currency and your merchant is paid in another, converted on the way. See [Payments](/markets/payments).
* **Run a register of merchants**, each with its own settlement asset, limits, screening tier and verification. See [Merchants](/markets/merchants).
* **Keep every channel funded.** See how long each asset and each payout channel lasts at today's pace, and when to top it up. See [Liquidity and Rails](/markets/liquidity).
* **Price every corridor** from reference rates plus your spread and fee, with a per-payment cap and a daily cap, and pause or halt any corridor at any time. See [FX and Pricing](/markets/fx).
* **Move funds under approval.** Every movement of the workspace's money on the hub is requested, approved by others, carried out and reconciled. See [Operations](/markets/operations).
* **Prove every action** in a hash-chained audit log you can verify yourself. See [Audit](/markets/oversight/audit).

## Built on the SQRL network

SQRL Markets is the desk for the Lightning distribution layer of the SQRL network. Your hub holds multi-asset channels; a payment that crosses currencies converts inside the payment and settles under one payment hash, or not at all; and net positions settle back to Bitcoin. For the protocol behind it, see [Partner hubs and in-flight FX](/protocol/lightning/hubs-and-fx) and [Batch settlement and finality](/protocol/lightning/batch-settlement).

  The hub's keys are yours. Liquidity sits in Lightning channels between your hub and each counterparty, and closing a channel returns its balances to you on-chain. SQRL never takes custody of it.

## Where to start

Hubs, channels, pockets, corridors, and the life of a payment.

Request access, sign in, and connect your hub.

Follow a payment from quote to settled, and decide holds.

Set up corridors and how each one is priced.
