# [[Temperature Check] Enable 1bp Fee Tier for UniswapV3 on Arbitrum](https://snapshot.org/#/uniswap/proposal/0x15031b68121659b87a3f5e33c303cd517bcbc003d3f60fc82f1299620475bcab)

**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](https://gov.uniswap.org/t/polygon-1bp-fee-tier/16488), and [Optimism](https://gov.uniswap.org/t/deploy-a-1bp-fee-tier-to-uniswapv3-on-optimism/16930), 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](https://info.uniswap.org/#/arbitrum/). 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.
