Simple Summary
It is proposed to add an Idle Finance Convex protocol (mUSDcrv) Perpetual Yield Tranches (PYTs) dial.
Abstract
Idle DAO developed 2 products based on mStable ecosystem in Ethereum:
- mStable PYTs, tranching the “Save” vault, where users can deposit mUSD tokens.
- Convex PYTs, tranching mUSD pool, where users can deposit mUSDcrv Curve LP tokens.
In short, Junior Tranches TVL covers Senior Tranches in case of losses, but they leverage Senior Tranches TVL to receive APYs higher than the underlying yield source. A wider range of users can deploy mUSD in the Save vault or increase the liquidity of mUSDcrv Curve pool through Convex – with Senior/Junior Tranches, they are now able to adjust their deposit depending on their risk profile.
This proposal suggests adding one dial for the Convex PYTs to receive additional MTA rewards and to incentivise this Junior Tranche.
Motivation
Idle DAO launched a “Tranches Battle” and selected mUSD as one of the contest winners. This resulted in the development of PYTs using mUSD pool on Convex. The integration has been completed, and is ready to be launched. It’s already visible on the Beta page.
In addition, Idle DAO approved the launch of Gauges to reward Senior Tranches with $IDLE farming (initially at 990 IDLE/day). mUSDcrv PYTs will be eligible to benefit from these streams.
The support for the Senior Tranches of mUSDcrv PYTs in MTA dial will allow mStable to incentivize Curve pool liquidity, enabling users to adjust their liquidity deployment to their risk profile.
PYTs features With Perpetual Yield Tranches, LPs can earn a higher share of yield by taking more risk (with Junior Tranche), or they can hedge risk by depositing their assets into an inherently protected tranche (with Senior Tranche). Senior Tranches have a first lien on the assets — they’re in line to be repaid first, in case of default.
PYTs are:
- Epochless, flexible, with no locking periods: you can deposit or withdraw your liquidity at any time;
- Fully fungible and composable ERC-20: other DeFi protocols and integrators can offer tailored products based on PYTs;
- High-quality yield-bearing collateral: the built-in fund protection mechanism available on Senior Tranches makes them more resilient against default scenarios and can benefit from higher LTV.
About PYTs Idle launched PYTs in late December, after 4 months of guarded launch. Idle PYTs’ smart contracts have been audited by two different professional auditing firms before the release (Consensys Diligence and Certik). All the related and previous audits for the Idle protocol are available here.

Specification
A new instance of the contract BasicRewardsForwarder will be deployed on Ethereum mainnet with the following parameters:
nexus = 0xAFcE80b19A8cE13DEc0739a1aaB7A028d6845Eb3(Nexus contract)rewardsToken = 0xa3BeD4E1c75D00fa6f4E5E6922DB7261B5E9AcD2(MTA Deployed address)
And initialized with:
emissionsController = 0xBa69e6FC7Df49a3b75b565068Fb91ff2d9d91780(Emissions Controller deployed address)endRecipient = 0x7f366a2b4c4380fd9746cf10b4ded562c890b0b1
This contract receives the MTA from the Emissions Controller and forwards it to the staking contract controlled by Idle Finance.
This contract will then be added to the Emissions Controller as a dial:
Emissions Controller (0xBa69e6FC7Df49a3b75b565068Fb91ff2d9d91780)addDial (address recipient, uint8 cap, bool notify)recipient= New deployed instance ofBasicRewardsForwarderas specified aboveuint8 cap = 0uncapped (only used for MTA staking contracts to cap)notify = truewill call the function to notify and process the MTA rewards upon disperse
