# Create v3deployments.uniswap.eth subdomain and populate its text fields
## Rationale
Per the discussion in the governance forums [here](https://gov.uniswap.org/t/rfc-post-bsl-cross-chain-deployment-process-new-uniswap-eth-subdomain/20878) and [here](https://gov.uniswap.org/t/temperature-check-post-bsl-cross-chain-deployment-process-creation-of-new-uniswap-eth-subdomain/20961), and the Snapshot poll [here](https://snapshot.org/#/uniswap/proposal/0x0f8a85d90759acf3a6fdc018e20b991f3562847122a8142c4e166c71d0e755e3), 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](https://app.uniswap.org/#/vote/2/25) and [Polygon zkEVM](https://app.uniswap.org/#/vote/2/34) have passed governance votes and will be added to the subdomain at a date in the future when their deployments are complete.
## Process
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](https://chainlist.org) 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](https://github.com/Uniswap/governance-seatbelt/actions).
1. Creates the new subdomain by calling the `setSubnodeRecord` on the ENS Registry and passing it the name hash for `uniswap.eth`, the label hash for `v3deployments`, the timelock's address, and the ENS public resolver's address.
2. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `42161` for Arbitrum and value `0x4Dbd4fc535Ac27206064B68FfCf827b0A60BAB3f, 0x1F98431c8aD98523631AE4a59f267346ea31F984`

4. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `137` for Polygon and value `0xfe5e5D361b2ad62c541bAb87C45a0B9B018389a2, 0x1F98431c8aD98523631AE4a59f267346ea31F984`
5. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `42220` for Celo and value `0xf7e46b233abd1edaad8dbbbda12129b97b071025, 0xAfE208a311B21f13EF87E33A90049fC17A7acDEc`
6. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `56` for Binance Smart Chain and value `0xf5F4496219F31CDCBa6130B5402873624585615a, 0xdB1d10011AD0Ff90774D0C6Bb92e5C5c8b4461F7`
7. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `100` for Gnosis and value `0xf5f4496219f31cdcba6130b5402873624585615a, 0xe32F7dD7e3f098D518ff19A22d5f028e076489B1`
8. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `43114` Avalanche and value `0xeb0BCF27D1Fb4b25e708fBB815c421Aeb51eA9fc, 0x740b1c1de25031C31FF4fC9A62f554A55cdC1baD`
9. Creates a new text record on `v3deployments.uniswap.eth` by calling `setText` on the subdomain and passing it the name hash for the subdomain, the key `288` for Boba and value `0x6D4528d192dB72E282265D6092F4B872f9Dff69e, 0xFFCd7Aed9C627E82A765c3247d562239507f6f1B`
