**[Gate Announcement on the Removal of ETH Exchange-Related APIs and Replacement Interfaces]** To further optimize the platform's API service architecture and enhance system stability and execution efficiency, Gate will officially discontinue ETH exchange-related API interfaces in the near future. Once the interfaces are removed, services and technical support will cease. Relevant developers are advised to complete interface migration and adaptation as soon as possible to avoid disruptions to normal business operations. **I. Interfaces to be discontinued** 1. ETH Exchange: POST/earn/staking/eth2/swap 2. ETH Historical Yield Rate Query: GET/earn/staking/eth2/rate_records **II. Replacement Interfaces and Details** The platform has already provided replacement interfaces that are functionally compatible and offer better performance, covering the capabilities of the original interfaces. Please switch to the new interfaces for API calls as soon as possible: - On-Chain Earn Exchange API: POST/earn/staking/swap **Interface Documentation:** [https://www.(gate.com)/docs/developers/apiv4/zh_CN/%E9%93%BE%E4%B8%8A%E8%B5%9A%E5%B8%81%E5%85%91%E6%8D%A2](https://www.(gate.com)/docs/developers/apiv4/zh_CN/%E9%93%BE%E4%B8%8A%E8%B5%9A%E5%B8%81%E5%85%91%E6%8D%A2) **III. Important Notes** 1. Please complete the interface replacement, integration, and testing work as soon as possible to ensure a smooth business transition. 2.
