The previous [Maintenance Grant](https://polkadot.polkassembly.io/motion/12) expired in August 2021. This grant is applying for maintenance retroactively since then, as well as future maintenance until the end of 2023.

Continuous maintenance is required because changes in the Polkadot SDK (Substrate) require regular upgrades of the [GSRPC](https://github.com/centrifuge/go-substrate-rpc-client/) library.

Currently, the repository is used by more than **500** Github [Go Modules](https://github.com/search?q=go-substrate-rpc-client+language%3A%22Go+Module%22&type=code&p=2&l=Go+Module) such as: *Snowbridge*, *Cosmos*, *Chainsafe*, *Chainlink* and *Bifrost* among others.

These users require regular support as well as fixes to the library. Centrifuge has been providing this support at no cost since September 2021, since the previous grant expired.

- Since project inception we have merged [197 PRs](https://github.com/centrifuge/go-substrate-rpc-client/pulls?q=is%3Apr+is%3Aclosed)
- And closed [103 issues](https://github.com/centrifuge/go-substrate-rpc-client/issues?q=is%3Aissue+is%3Aclosed)

**Maintenance Responsibilities**

k-f as one of the main contributors to GSRPC has been committed to:
- Maintain project's documentation
- Be diligent on answering issues and engage in discussions
- Fix reported bugs
- Review Pull Requests and guide developers on understanding the code promoting community involvement.
 
**Main issues we have fixed:**
- Keep up to date with new Substrate/Polkadot/Cumulus core types used when interacting with a Substrate chain. Please note that this does not include support for new metadata versions. Given the unknown amount of work required for such a task, we plan on tackling those separately, in a following grant.

**Additional Information**

Please ignore our previous [Referendum 206](https://polkadot.polkassembly.io/referenda/206) which requested the incorrect amount.
