Per the discussion in the governance forums here and here, and the Snapshot poll here, canonical deployments of Uniswap v3 will be recorded in a new subdomain. This proposal seeks to create that subdomain (v3deployments.uniswap.eth) and populate its text records with all deployments that were granted business source license exemptions and those that have passed governance votes since the license's expiry.
One thing to note - both zkSync and Polygon zkEVM have passed governance votes and will be added to the subdomain at a date in the future when their deployments are complete.
If executed, this governance proposal will make 9 function calls. At a high level, the first transaction creates the new subdomain and the next 8 add text records to it. The text records are formatted such that the key is the network number of the chain in question and the value is a string with the address of the bridge sender contract on mainnet associated with the deployment followed by the UniswapV3Factory address on the destination chain, separated by a space and a comma. Note that this is a slight departure from what was suggested in the forums; after discussing with various members of the governance community it became apparent that including the factory address would be a valuable addition.
We describe the function calls in more detail below, and a detailed simulation of the transaction's execution will be available shortly after this proposal goes live by downloading the Uniswap artifact at the bottom of this page.
