Summary
This proposal outlines the strategic expansion of Ether.fi Ether (eETH) on Fluid. These changes will enable greater usage and improved APRs on the weETH markets, increase the weETH/wstETH borrowing limit and bring 2.5x Ether.Fi points boost for Fluid depositors. This proposal also enhances APRs through Lite Vault deleveraging.
Proposal
By maintaining Ether.Fi’s eETH asset as the primary LRT asset on Fluid, users will receive 2.5x Ether.Fi points on their weETH deposits. Ether.fi deep liquidity and live withdrawals makes it the safest choice for the Fluid protocol and the following changes will expand and improve the weETH markets and utilization on Fluid. In addition we plan to propose support of weETH/USDC and weETH/USDT vaults in coming weeks. The Instadapp Lite vaults will utilize and move stETH funds into Fluid allowing to grow the weETH market further.
Deleveraging Lite Vault and APR Enhancement
Direct withdrawals from Lido have commenced for Lite Vault deleveraging, with this the Lite Vault can shift up to 25k stETH into Fluid over the forthcoming weeks. This transition can significantly elevate the APR for Lite Vault users to up to 20%, capitalizing on the higher wstETH yields available through Fluid Vaults.
Vaults
Update weETH/wstETH Vault
- Current Borrowing Limit: 10k
- New Borrowing Limit: Variable (85% of wstETH total supply)
In the previous proposal, there was some criticism received around increasing the borrowing limits. Its important to understand that the borrow cap is there to ensure security and not meant to restrict rates. As the caps are increased the borrowing rates will be decided by user demand, keeping borrowing limits low creates artificial rates and makes the protocol less competitive.
Maintaining the current rates while increasing borrowing limits may produce a situation where utilization is beyond the second kink at 80%. Once this occurs borrowers will face losses, this is avoided by enabling larger caps so the market can adjust. Therefore its important to both enable more borrowing and update the rates.
Update wstETH/USDC Vault
- Current Supply Rate Magnifier: 1x
- Proposed Supply Rate Magnifier: 0.8x
Update wstETH/USDT Vault
- Current Supply Rate Magnifier: 1x
- Proposed Supply Rate Magnifier: 0.8x
To maintain balance between ETH and wstETH rates, we propose making the supply magnifier 0.8x for wstETH/USDC and wstETH/USDT. This ensures that wstETH collateral remains aligned with ETH supply rates. This will help prevent any massive disruptions between these two markets. Furthermore, this enables wstETH lenders to earn an attractive APR on both the lending protocol and as collateral in the wstETH/ETH Vault.
Liquidity Layer
Rate Curve Adjustments for ETH & wstETH Markets
These adjustments are proposed in response to market demand with considerations for similar markets on Pendle and Gearbox, we propose rate curve adjustments for the wstETH market to align borrowing rates between 25-35%.
Current wstETH Rate Curve
- Utilization 0%: 0% Rate
- Utilization 50%: 15% Rate
- Utilization 80%: 30% Rate
- Utilization 100%: 150% Rate
Proposed wstETH Rate Curve
The new wstETH rate curve adjustments are as follows:
- Utilization 0%: 0% Rate
- Utilization 70%: 20% Rate
- Utilization 90%: 40% Rate
- Utilization 100%: 150% Rate
In conjunction with enabling wstETH on the lending protocol (See below) These proposed rates aim to better align the market to similar competitors while improving rates for suppliers.
We also propose updating the fee in the wstETH market to 10%.
Current ETH Rate Curve
- Utilization 0%: 0% Rate
- Utilization 70%: 2% Rate
- Utilization 90%: 3.6% Rate
- Utilization 100%: 100% Rate
We propose making the ETH Market fee 0%.
Proposed Rate Curve for ETH Market:
- Utilization 0%: 0% Rate
- Utilization 70%: 15% Rate
- Utilization 90%: 25% Rate
- Utilization 100%: 150% Rate
The proposed ETH Curve is aligned to mirror the rate curve of wstETH. This maintains that supplying ETH will remain attractive and profitable.
Lending
Enable wstETH on the Lending Protocol
We propose the activation of Wrapped Staked ETH (wstETH) within the lending protocol, this will enable wstETH liquidity to be supplied on the lending protocol.
Proposed wstETH Lending Configs
Base Withdraw Limit: 4000 wstETH
Expand Percentage: 25%
Expand Duration: 12 hrs
Pausing ETH Vault Rewards
In light of the proposed rate curve adjustments, which could potentially double the current supply APR, we propose pausing the ETH rewards to make best use of incentives.
Reason
This proposal strategically aligns Fluid with Ether.fi and enables Fluid users the opportunity to amplify their EtherFi points accumulation by 2.5x and benefit from increased APRs. The proposal to update the Supply Rate Curve, in combination with deleveraging the Lite vault, will bring increased revenue and improve APRs for both the protocol lenders and borrowers.
Result
This proposal deepens integration of the weETH market by making the following changes:
- Enables wstETH on the Lending protocol
- Updates the Rate Curve for wstETH and ETH on Liquidity Layer
- Increases the weETH/wstETH Vault to variable Borrowing Limit
- Pauses ETH Rewards on ETH/USDC and ETH/USDT vaults
- weETH users will receive 2.5x Ether.fi Points
