# Deployed contracts

Yield Tranches are deployed on multiple chains. For each chain, we list the different pools available following this scheme:

* CDO = Main YTs contract address
* Senior = Senior tranche LP token (AA)
* Junior = Junior tranche LP token (BB)

The ABI of the Yield Tranches contract can be found here: [JSON](https://github.com/Idle-Labs/idle-tranches/blob/master/abi/IdleCDO.json).
