Background

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

Proposal

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

• Clearpool USDC (Portofino) YTs, with specs available on GitHub here

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

@Biaf

By integrating Clearpool USDC (Senior) tranches as a new yield source for the USDC BY strategy, we can create a two-side benefit for the Idle protocol:

1. The USDC BY strategy can add a new yield source, besides the usual Aave and Compound, able to offer an average APY in the 5% to 10% range. Currently, Aave and Compound offer APYs lower than 1%. This significant increase in yield can benefit current BY LPs and attract new users to the protocol.
2. The USDC BY funds flowing to the Senior side of Clearpool PYTs can create a stable source of funding for the Senior tranches and consequently incentive new Junior liquidity deployments thanks to the boosted APYs available (with an expected average APY in the range of 10% to 20%).

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.

Rating example: uncollateralized lending

Using the framework described above, we can rate the newly launched Clearpool’s (Portofino) as follows
