> This proposal was converted into [motion#419](https://polkadot.polkassembly.io/motion/419) and passed with 8 votes. However, it appears that an executed error occurred with motion #419, potentially due to the recent upgrade of the opengov system. For error detailed, please refer to [here](https://polkadot.subscan.io/extrinsic/16030233-2?event=16030233-41).


**Overview**

Subscan is an essential block explorer and analytics tool for the Polkadot network, providing valuable insights to the Polkadot community. However, the maintenance and operation of Subscan requires a significant investment of resources, including server infrastructure, security, and personnel costs. Therefore, we propose reimbursing the operation and maintenance fee for Subscan from July to December 2022 from the Polkadot treasury to ensure its continuous operation and maintenance.

**Total**

We believe that this reimbursement proposal will help to ensure the continuous operation and maintenance of Subscan, and benefit the growth and development of the Polkadot network. This time, we plan to apply for a total of 190,244 USD in Polkadot, the amount of DOT will be converted based on the EMA7 price on the day of the official submission.

Billing details can be read [here](https://docs.google.com/document/d/13whK83g_MXYCfQ4WyJmQuM_aTclCGsB9Ww9Pq3lP6dY/edit?usp=sharing).

We fully understand the necessity and unforeseen nature of the opengov upgrade. Consequently, I am resubmitting the opengov referenda in accordance with the most up-to-date EMA7 exchange rate. We sincerely hope to receive your support or feedback.


- This is a proposal to get money back for Subscan's costs from July to December 2022.
- Subscan helps people see what's happening in the Polkadot network.
- It needs a lot of resources like servers and security to work well.
- The last proposal had a problem because of a recent system upgrade.
- They want to get back $190,244 to keep Subscan running smoothly.
- The amount of money needed will be based on the current exchange rate.
- They are asking for support and feedback from the Polkadot community.
