# Streamline DevEx: Mobile, Rust and Web dev
**Estimated date of completion**: 30 Nov
**Resources Required for 2025H2**:
- nwaku 3 eng during 6 weeks
- js-waku 2 eng 6 Week Sep
Complete the Waku API implementation in nwaku by implementing edge node mode (Status' Light Mode).
Streamline the Developer Experience by delivering a Rust SDK that implements the full Waku API and is available on crates.io.
As well as building an easy-to-use local dev environment from the browser, enabling developers to build web apps without
relying on external connectivity. Provide a similar harness to deploy a local RLN dev environment.
Finalize the integration of nwaku in Status application by setting up nwaku-based build for Mobile platforms.
Lastly, develop a PoC protocol to demonstrate the usage of Waku as a Signal network, using WebRTC as example.
This was identified as a demanded demonstration of Waku's capabilities as part of the [Waku MVP analysis](https://www.notion.so/Waku-MVP-1838f96fb65c8039acabf8a6a1e689e7).

## Risks
| Risk | (Accept, Own, Mitigation) |
|-------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| nwaku performance | Performance of nwaku in comparison to go-waku will be measured by DST during H2 and may raise issues that will become blockers for pratical usage of nwaku in Mobile. |
| Publishing to crates.io | One of the challenge to publish libwaku on crates.io is the package size. Several strategy may be developed and tried to find a way to distribute Nim-based Rust crates. |
| Local dev harness | Creating a local dev environment may be a challenge due to the nature of Waku and RLN, as we would need to locally coordinate bootstrap and blockchain emulation. |
