[GENERAL] Please indicate if your proposal has been auto-translated into English from another language

Yes

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

Enhance the MeshJS SDK with auto-fallback multi-provider habilities and greatly enhance the diversity of data sourced from bare data providers and flowing through Mesh.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

No

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

[SOLUTION] Please describe your proposed solution

On a high level, we will enhance the MeshJS SDK with auto-fallback multi-provider habilities and greatly enhance the diversity of data sourced from bare data providers and flowing through Mesh.

Please refer to the Milestones breakdown for greater detail.

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

The hability for a dApp developer to focus on a sigle source of data, abstracting away the nuances in specific providers can greatly fast track Cardano dApp development.

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

45B is composed of and has access to professionals with an extensive track record of delivering solutions in Finance, Banking and other lines of business. Also they are responsible in helping the promotion and socials of some players in the Cardano ecosystem.

Having deep understanding on how the Cardano blockchain can be used, we are in an ideal position to take this project forward. Many of the components of this project/budget will be extended to Cardano community developers sponsored by bounties from this proposal.

[PROJECT MILESTONES] What are the key milestones you need to achieve in order to complete your project successfully?

Surveying and gathering community engagement - 2 months

• Reach out to existing apps using Mesh
• Apps that would move to Mesh having this
• Measure the gap and assess their requirements

Multiprovider fallback mechanism - 2 months

• Enhance Mesh with the configuration of
• An array of providers/keys
• Priority and other settings per provider
• Improve behaviour so that on failiure/timeout try next provider
• (be intelligent about 404s that are not errors in some providers)
• Community testing and implementing fixes from feedback
• Gather/Prepare endpoint/data requirements to add to mesh

Enriching endpoints and data structures - 2 months

• Consider importing data provider SDKs
• Extensively implement endpoints/data to include

Enhance extensibility - 2 months

• Get and Post "Passthrough" Mesh endpoints
• Enable a dApp to hit any custom provider endpoint
• Document with examples how to transform these responses
• Document how to PR Mesh to add further data

Making it Language agnostic - 2 months

• Docker container wrapping the Mesh SDK
• Enable+test REST queries into the container
• Misc unit testing and (performance) optimizations / test cases

Final milestone

• Share learnings with the community
• Gather learnings and resources
• Make learnings and resources public in a friendly format
• Discuss learnings and resources with the Catalyst community both asyncronously and on a public call

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

This project can save all dApp developers on Cardano time and effort, bring stability to their apps.

Unlike most proposals who simply aim for the max amount in that Category, we are providing a reasonable estimate for the effort we will put in.

The services budget is according to or below standard rates for these professional services in Europe or the USA.
