Please describe your proposed solution

We will build a framework (TypeScript) to work in the Cloudflare Edge environment, namely Cloudflare Workers. This is a Node.js environment with instant deployment of instances across the globe, which allows us to use serverless code. The project will be completely open source.

The framework will utilize technologies and libraries such as:

• Cloudflare Workers, serverless code instantly across the globe
• Cloudflare KV, global, low-latency, key-value data storage
• Cloudflare D1, serverless SQL databases
• Hono, router for any JavaScript runtime
• Zod OpenAPI Hono, OpenAPI schemas for Hono
• Drizzle ORM, TypeScript ORM for Cloudflare D1
• @dcSpark/cardano-multiplatform-lib, serialization & deserialization of core cardano data structures
• @emurgo/message-signing-lib, CIP-0008 message signing

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

The Cardano ecosystem should be developer friendly, and the first steps in development should be very simple and straightforward. This framework will allow you to deploy frontend/backend applications literally instantly, without tedious server configuration.

Combined with XRAY/Graph (data provider) and CardanoWeb3js (Lucid analog developed by XRAY/Network) it will become a universal solution for creating various applications and APIs.

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?

We've done quite a bit of product development and understand how and what goes on in Cardano.

• CardanoWeb3js (Cardano JS SDK)
• RayWallet (lightweight wallet)
• RayStake (+ first Cardano ISPO)
• XRAY/Graph Nftcdn (metadata explorer, image CDN, IPFS proxy)
• XRAY/Graph Output (Cloudflare Workers load balancer)
• XRAY/Graph Turbo TX Send (Cloudflare Workers multiple node tx submission)
• Koios Tiny (dockered Koios)
• cardano-koios-client
• cardano-nftcdn-client
• And so on, many projects are in the pipeline

Please provide a cost breakdown of the proposed work and resources

Milestone 1:

$50/hr x 2 months x 80 hr/month = $8,000

Milestone 2:

$50/hr x 1 month x 80 hr/month = $4,000

Final Milestone:

$50/hr x 1 month x 80 hr/month = $4,000

TOTAL ($) = $16,000

TOTAL ($0.45/ADA) = ~35,000 ADA

No dependencies

How does the cost of the project represent value for money for the Cardano ecosystem?

Blockchain developer hourly rates are charged at an international industry standard of ~$50 an hour. Reference: https://survey.stackoverflow.co/2023/#work-salary
