SQRL Markets

#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 and Payments.
• Liquidity providers fund corridors, set their charge and daily cap, and earn the spread on each payment. Start with Liquidity and Rails and 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.

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.

#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.
• Run a register of merchants, each with its own settlement asset, limits, screening tier and verification. See 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.
• 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.
• 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.
• Prove every action in a hash-chained audit log you can verify yourself. See 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 and Batch settlement and finality.
