ARC-139: Reduce PCL pool fee range

Proposals ARC (Astroport Request for Comments)
1

Summary

This proposal aims to update the default parameters for Astroport’s Passive Concentrated Liquidity (PCL) pools to optimize price execution in light of recent declines in volume. By lowering the fee spread, the proposal seeks to strike a balance between incentivizing trading and maintaining LP profitability. The new parameters will be applied as the default for all PCL pools moving forward, including the top 15 TVL PCL pools with a minimum of ~50k$ liquidity on Neutron and Terra, and will align with the optimized fee structure previously used on the Osmosis deployment.

Motivation

The current PCL fee parameters are effective when there is significant volume and liquidity, but with the recent lack of trading volume, the yields have become less appealing. Lowering the fee spread can incentivize trading by offering better price execution, which in turn can drive higher volumes and improve fee accrual for LPs.

Applying the concept of the Laffer Curve, we intend to adjust for an optimal balance between fees and volume where the most revenue can be generated. By adjusting the fee parameters, Astroport can find this sweet spot and maximize protocol efficiency. Additionally, the proposed changes align with the fee structure previously implemented on Osmosis (0.05% - 0.2% fee) that kept PCL pools competitive in the face of the additional fees applied on top of PCL fees.

Implementation

  1. Update Default PCL Parameters:
    • Replace the current default PCL parameters with the new values:
      • Amp: 10
      • Gamma: 0.00018125
      • Mid Fee: 0.0005
      • Out Fee: 0.002
      • Fee Gamma: 0.00023
      • Profit Threshold: 0.0000002
      • Min Price Scale Delta: 0.000146
      • MA Halftime: 600
  2. Apply New Parameters to Top 15 TVL PCL Pools:
    • Update the fee parameters for the top 15 PCL pools by TVL with a minimum of ~50k$ liquidity to reflect the new default values.
  3. Monitor Performance:
    • Track trading volume, LP profitability, and fee accrual after the changes to ensure the new parameters achieve the desired balance between trading incentives and LP returns.
    • Adjust further if necessary based on performance data.

Conclusion

Reducing the PCL fee range will make Astroport’s PCL pools more competitive in the current market environment, improving price execution while maintaining LP profitability. By applying the optimized fee structure to the top 15 TVL PCL pools with a minimum of ~50k$ liquidity and setting it as the default for all PCL pools, Astroport can adapt to changing market conditions and maximize protocol efficiency. This proposal ensures Astroport remains competitive and responsive to its ecosystem’s needs.
