Overview
Inflation is directed to users who provide liquidity within the protocol. This usage is measured via “Liquidity Gauge” contracts. Each pool has an individual liquidity gauge. The Gauge Controller maintains a list of gauges and their types, with the weights of each gauge and type. For implementation details see here.
Contract Source & Deployment
There are several versions of liquidity gauge contracts in use. Source code for these contracts is available on Github.
Easiest way to obtain the gauge address of a liquidity pool is by querying get_gauge on the MetaRegistry.
Gauge Types¶
Each liquidity gauge is assigned a type within the gauge controller. Grouping gauges by type allows the DAO to adjust the emissions according to type, making it possible to e.g. end all emissions for a single type.
Warning
Types 3 and 6 have been deprecated.
