ChainSafe #3 - Zcash Metamask Snap and Webzjs maintenance renewal
Declined
ChainSafe requests a second year of maintenance funding for WebZjs, their JavaScript browser library for Zcash wallets, including the MetaMask Snap and associated browser wallet. Work covers security updates, protocol compatibility, stability, and additional features as agreed with the committee. Requesting $168,000. Artkor: When we approved the one-year maintenance grant, the library was still new, and first-year support made sense because bugs often surface after real-world use. However, ZCG cannot fund library maintenance indefinitely. At this stage, I think we should move to a more targeted model, where specific issues can be funded individually based on urgency, effort, and ecosystem value. Hanh: Yeah, that makes sense. I would say that the previous model was to have a funding subscription model where the developer would fix issues and make improvements, and then bill based on the task and effort made. But unfortunately I think that didn’t work out in practice because we didn’t see much response to issues and bugs reported in the forum. So in my opinion the idea was good but the execution was not as good. Therefore it would be better to go with the model where we offer bounties or rewards for actual work getting committed and bugs being fixed. Gguy: Yeah I definitely see there is a need for this library. But going forward we’d like to work with real users and their needs and respond accordingly. We’ll continue to look into ways to provide support for the users that are currently or future using this. Zerodartz: WebZjs is an important tool. The previous maintenance was at times very delayed. For example NU6 upgrades took way too long which made the wallets using this library basically unusable for a while. I think it’s a good team but for some reason they weren’t timely enough with updates to the library when needed. Decentralistdan: the webZjs library needs to be maintained but we should be looking at alternative ways to reach that goal
