+tagline: Provide liquidity on the TDEX Network, an open protocol to trade Liquid Network assets.
+description: >-
+  A liquidity provider holds Liquid reserves of both a BASE_ASSET-QUOTE_ASSET in his non-custodial Liquid hot-wallet,
+  running automated market-making strategies, either with or without an oracle. Providers are incentivized to
+  be always on and need to expose a public reachable endpoint either via clearnet or using an Onion hidden service.
+  
+  
+  A small provider's fee can be taken out of each trade and added to the reserves. A liquidity provider has full control
+  over the market making strategy needed to calculate the market rate at which to accept trades. That being said,
+  there is a possibility to apply an automated market-making strategy relying only on the reserves balances and the amount requested
+  by the trader, without the need to connect to an external price feed. The default strategy of the alpha daemond is the
+  constant product market-making. In short, this model generates a full order-book based on an initial price for the market.
+  Every transaction that occurs on this market will adjust the prices of the market accordingly.
