Proposal Summary

  • The purpose of this post is to apply canonical Uniswap V3 deployment on World Chain
  • All of the Uni v3 contracts have already been deployed
  • No further actions need to be taken by the DAO.

About World Chain

World Chain is a blockchain designed for humans. It is part of the Optimism Superchain Network. The Worldcoin ecosystem is currently built on Optimism, however, Worldcoin already accounts for ~50% of all transactions on Optimism main net. With plans for further growth a dedicated chain is needed.

The World app has a deep integration with Uniswap on Optimism. This proposals seeks to verify as canonical an existing Uniswap V3 deployment on World Chain. This will enable continued usage of the Uniswap V3 protocol.

Proposal Stakeholders

Proposer: World Foundation

Deployer: Tools For Humanity / GFX Labs

Bridge Provider: Alchemy

Target Chain: World Chain

Proposal Sponsor: N/A

Deployment Details

As is the case with all canonical v3 deployments, this deployment will be subject to Ethereum Layer 1 Uniswap Protocol governance and control. The text record of the uniswap.eth ENS subdomain titled v3-deployments.uniswap.eth will be amended by the Accountability Committee to include the reference to the stated v3 contracts. The below contracts have been verified.

Hi,

In my view, it’s necessary to include Permit2 and UniversalRouter contracts in any canonical Uniswap V3 deployments. Would it be possible to add these to your chain?

  • Permit2 gives significantly better and more secure UX for swappers.
  • UniversalRouter will help with integrations. For one, the Uniswap Labs UI needs it.

See this post for a list of contracts present on other chains: https://gov.uniswap.org/t/official-uniswap-v3-deployments-list/24323/2

Hi @kfx, thank you for your response.

Yes, both of these contracts are now deployed:

Permit2: 0x000000000022D473030F116dDEE9F6B43aC78BA3

Universal Swap Router: 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D

The original post above has been updated to reflect that as well.
