Clearpool YTs as a new yield source for USDC BY - Portofino


Treasury League


A proposal to add the Portofino Clearpool USDC Yield Tranches as a new yield source for the USDC Best Yield strategies.



After the recent exploit on Euler, Leagues have suggested to remove the Euler Yield Tranches from the basket of yield source of Best Yield strategies as a precautionary measure before a new audit is completed.

The current yield source of the Best Yield strategies would then be:

Strategy Token Underlying markets
Senior BY DAI Aave, Compound, Euler
Junior BY DAI Euler, Morpho


This proposal aims to add a new Clearpool Yield Tranche to the Best Yield strategies based on USDC:

Similar to previous Clearpool’s integration, Portofino’s one would benefit doubly the Idle users

Yield Tranches are live since December 2021 holding a cumulative TVL of up to $50m.

Portofino details

Portofino technologies is a high-frequency trading market maker that uses borrowed funds as trading capital, providing superior returns thanks to its advanced machine learning & stochastic control techniques.

Clearpool (Portofino) pool is live since early March. The Portofino pool has a size of ~$4.7m and a maximum borrowing capacity of up to $28m. Credora rates the borrower with an A.

Protocol Borrower Capacity Pool size Credora’s rating
Clearpool Portofino $28,624,138 4,754,744 A

At the time of writing, the Portofino pool provides 10.99% APR with a 64% utilization rate (source).

Risk rating

Following the new version of the risk rating framework, the Clearpool (Portofino) Yield Tranches can be considered as a valid market to become a new yield source of the Best Yield strategies.

In order to trigger any BY deployment, the Yield Tranches will need to have at least a 30% coverage on Senior funds coming from the Junior counterparty.

Next steps

We are going to leave this thread open for comments regarding this proposal, and tomorrow, if there are no objections, we will open the temperature check.
