From 46057c33f8279e39a418905b40dc29ad08ac5a63 Mon Sep 17 00:00:00 2001 From: Derek Brans Date: Thu, 13 Jun 2024 13:48:38 -0400 Subject: [PATCH] chore: revert recent gas api endpoint changes (#25230) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit > [!NOTE] > Once this PR is merged into develop, it will be cherry-picked into the next 11.16 hotfix as well as v12.0.0. We need to move quickly on a hotfix for the Extension due to a caching issue with the [infura.io](http://infura.io/) endpoint. The [API team has asked](https://consensys.slack.com/archives/C05B78N1T9B/p1717783170599949) us to revert a recent gas API endpoint change until the issue is resolved, which could take months. Here is what is in this PR: - apply patch using core patch branch MetaMask/core/pull/4403 - revert #23717 The renaming of `chunk` files in the `dist` folder of the gas-fee-controller are the cause of the large .patch file. For more context, see this [slack thread](https://consensys.slack.com/archives/CTQAGKY5V/p1718123930090259?thread_ts=1718123750.012709&cid=CTQAGKY5V). Although `transaction-controller` and `user-operation-controller` depend on v17, they can be safely ignored. The only runtime dependency those packages have is on the [enum-like GAS_ESTIMATE_TYPES](https://github.com/MetaMask/core/blob/dcc1d9291297ca2106cd2a461c51ce2f4667d84d/packages/gas-fee-controller/src/GasFeeController.ts#L61-L66), ([example1](https://github.com/MetaMask/core/blob/dcc1d9291297ca2106cd2a461c51ce2f4667d84d/packages/user-operation-controller/src/utils/gas-fees.ts#L224), [example2](https://github.com/MetaMask/core/blob/dcc1d9291297ca2106cd2a461c51ce2f4667d84d/packages/transaction-controller/src/gas-flows/DefaultGasFeeFlow.ts#L41-L62)) which hasn't be touched in [3 years](https://github.com/MetaMask/core/pull/494/files#diff-ac8f6d6d8ff039810f56d99da8735d4eb8c2978eed2685b1741c9124c7b8bb6fR47-R52). 1.
