# Liquidity Providers

> How independent providers supply inventory for routed onramp, offramp, and swap orders.

**Liquidity providers** hold inventory — fiat in bank accounts and crypto in on-chain wallets — and fulfil orders routed by Liquidramp. You never interact with a provider directly; routing is automatic.

At quote time, Liquidramp selects a provider that can fill the corridor. Optional `provider_id` on quote or order requests pins a specific provider when you already have one.

When an order is created, a provider is assigned and you may receive an `order.assigned` webhook. Pay-in instructions in `payin` tell your customer where to send funds.

If you **are** a liquidity provider, run a provision node and register its HTTPS URL in the portal. See [Provision node setup](/liquidity-providers/node-setup).
