Hi all,
I just restructured the proposal with the first step into a votable one. @mdong shall I create a snapshot vote for this?
CIP-12 Improve the liquidity efficiency of cBridge - Step 1
This proposal focuses on the first step of improving the liquidity efficiency of cBridge.
Step 1: Align Liquidity Incentives with Overall Demand
Although not directly tied to the transition, this step should be implemented regardless. The current LEF indicates that the reserve liquidity significantly exceeds the liquidity actually required. Based on daily volumes and demand, we suggest the following liquidity reward reduction schedule to better align with the real demand for cross-chain bridging. The Adjust Ratio is defined as the ratio between the new liquidity reward emission rate and the previous one.
Proposed Adjust Ratio | Arbitrum One | Avalanche | BNB Chain | Ethereum Mainnet | Polygon | Optimism | Astar | Aurora |
---|---|---|---|---|---|---|---|---|
USDC | 0.2 | 0.2 | 0.3 | 0.3 | 0.2 | 0.2 | 0.05 | 0 |
USDT | 0.2 | 0.2 | 0.3 | 0.3 | 0.2 | 0.1 | N/A | 0 |
WETH | 0.2 | 0.1 | 0.2 | 0.3 | 0.2 | 0.2 | N/A | N/A |
Note that we propose Aurora should be removed from the support of liquidity pool-based model because of its minimal usage.
This step should proceed irrespective of the Peti model switch, given the current excessively low LEF. Adjusting the liquidity rewards can generally improve liquidity efficiency, and by decreasing overall liquidity, it creates more room for professional liquidity providers operating under the Peti model. The proposed adjustment schedule is extremely conservative and highly unlikely to affect current bridging usage. In fact, we suggest that the ideal LEF should be around 1.5 (ten times the current value), necessitating a total liquidity reduction of approximately 10 times. However, the adjustment itself is not that drastic to avoid any unforeseen issues. Following this adjustment, we recommend that the community continually evaluates the LEF and makes necessary adjustments on a monthly basis.
