Patract Hub’s treasury proposal for Elara v0.2

Github: https://github.com/patractlabs/elara

Patract Hub is a community based non-profit organization, developed and maintained by Patract Labs. We develop local open source toolkits and one-stop cloud smart IDE, dedicated to provide free development toolkits and infrastructure services for the entire smart contract ecosystem.

Elara's goal is to build a similar infrastructure and network public access services to provide developers with a unified access layer based on Substrate multi-chain. In addition, Elara will be used as part of the smart contract development service, and will be integrated with other components of the Patract toolchain in the future, in terms of contract development environment support, development tools component, contract deployment and DApp release. Elara will be Polkadot’s infrastructure, allowing developers to focus on building upper-level applications.

Summary of Elara’s future plan:

~~v0.1: Implement a server-side framework and proxy access to automatically monitoring and provide statistics for the Substrate node’s RPC service~~
v0.2: Expand features about developer’s account management, project management, data access and traffic statistics to provide public access services for Polkadot
v0.3: Performance optimization and architecture upgrade, support multi-chain architecture, access to multiple mainnets in the Polkadot ecosystem
v0.4: Automatically access and maintain blockchains in Polkadot ecosystem

We have finished the development work of Elara v0.1 on time, and written a treasury report at https://polkadot.polkassembly.io/post/139. This proposal focuses on Elara v0.2, and will continue to develop the following features on the basis of v0.1.

Implement the account space features, supporting developers to use Github as a third-party login system to create an account space.
Support the creating and management of multiple projects under the developer’s account space
Provide developers with detailed access statistics features on the single project dimension, showing statistical indicators such as daily and weekly requests, calling methods, and source of user groups.
Officially launch https://elara.patract.io, providing the community with public access services to the Polkadot mainnet
