[RFC] Enable a 1bp fee tier for UniswapV3 on Arbitrum

Thesis:

This proposal seeks to deploy a 1bp fee tier for UniswapV3 on Arbitrum. This will allow users to trade with lower fees, making it more accessible and competitive with other decentralized exchanges.

Since the launch on mainnet, there seems to be enough data to prove the effectiveness of a 1bp fee tier in increasing swap volume for Uniswap.

Currently, the Uniswap 1bp fee tier is live on the mainnet, Optimism and Polygon. Based on data and the impact it’ll have on the trading volumes, there’s no reason for it not to exist for Arbitrum.

Benefits:

  1. Lower fees will make Uniswap more accessible to new users and traders on Arbitrum, who may have been deterred by higher fees.
  2. As liquidity is more concentrated, 1bp pools will be more capital efficient too.
  3. Lower fees may also encourage traders to engage in more frequent trading, which can help to increase the overall volume and earnings for liquidity providers.

Why Arbitrum:

Given the positive outcome from the deployment of the 1bp fee tier for UniswapV3 on the mainnet, Optimism and Polygon, there’s no logical reason why Arbitrum must be left behind.

Arbitrum has a thriving ecosystem of DeFi dapps that will benefit from this. With Curve’s liquidity bribing mechanism losing efficiency, it is ideal for dapps to seek greener pastures. An easy and straightforward alternative to attract on-demand liquidity is to couple native token incentives with the option of 1bp pools. Without this, the devs may decide to use another DEX to build liquidity for their token.

[Temperature Check] Enable 1bp Fee Tier for UniswapV3 on Arbitrum

By GFX Labs & ConsenSys

Rationale:

This proposal seeks to deploy a 1bp fee tier for UniswapV3 on Arbitrum. This will allow users to trade with lower fees, making it more accessible and competitive with other decentralized exchanges. The optionality of a 1bp fee tier is useful for stable-to-stable swapping and can often be found among the top ten liquidity pools on each of Uniswap’s respective deployments.

Since the launch of the 1bp fee tier on mainnet, Polygon, and Optimism, the 1bp fee tier has directly led to growth in Uniswap’s DEX market share and directly competes with stablecoin DEX protocols.

Benefits:

  • Lower fee tiers increase competitiveness and incentivize more user activity.
  • As liquidity is more concentrated, 1bp pools are more capital efficient, especially for stable-to-stable swaps.
  • Lower fee tiers can also lead to increased volume and earnings for liquidity providers.

Why Arbitrum:

Favorable outcomes from deploying the 1bp fee tier on all other existing Uniswap v3 deployments make this an uncontroversial upgrade of the Arbitrum deployment.

Arbitrum has a thriving ecosystem of DeFi dapps that will benefit from less stable-to-stable friction. The Uniswap deployment on Arbitrum currently has ~200M of TVL and ~160M of volume. With Curve’s liquidity bribing mechanism losing efficiency, Uniswap is in a strong position to compete for traders’ flow and LPs’ liquidity by providing more competitive fee tiers.

Thanks @GFXlabs for formalising this proposal and putting it up for a Snapshot!

We are in full support and think the 1bp implementation is important for Uniswap’s competitiveness on Arbitrum.

Not necessary. There isn’t enough incentive to LPs.
