A liquidity provider supplies assets or executable quotes that allow other market participants or payment services to buy, sell, or convert value.
In stablecoin markets, liquidity can be supplied through centralized market making, exchange order books, over-the-counter desks, automated market maker pools, or payment-provider inventory. A payment service can use liquidity providers to convert between stablecoins, fiat currencies, or other digital assets. The provider earns spreads, fees, or other compensation while taking inventory, market, and counterparty risk.
A liquidity provider supplies tradable inventory or quotes. A payment processor can use that liquidity without being the entity that ultimately provides it.
Liquidity providers influence conversion costs, slippage, market depth, and the ability of payment systems to execute large transactions near quoted rates.
A market maker can quote simultaneous buy and sell prices for USDC against another currency and fill conversion orders for a payment provider.
