[IMPACT] Please describe your proposed solution.

DCOne Crypto is an ecosystem in the Cardano space. For the developers who want to build their products on the Cardano blockchain, it requires knowing Cardano Wallet, Cardano GraphQL, Cardano DB Sync, DevOps, Infrastructure Management, Server Administration, System Security, System Maintenance… can cost 2500-3500$ per month. This affects the ambition of developers from forming new ideas or developing their products. We provide APIs, Webhooks, SDKs…etc for developers that are easy to use and extensible, build more apps, and attract more users to the Cardano blockchain. All functions are run on Testnet before using it on Mainnet.

The component will be provided by us as follows:

• HTTP API, REST API, WCF
• Webhooks
• JS SDK
• IOS SDK
• Android SDK
• Notify Mobile
• Notify bot Telegram, Discord
• Check balance via Telegram bot, Discord
• Look up transaction history via Telegram bot, Discord
• Mobile Push Notifications
• Email
• Data stream
• AWS Data Streams

DCOneCrypto HTTP REST API: The most trusted and accessible DCOneCrypto HTTP REST API (https://dconecrypto.finance/) that makes it easier and faster for application developers to maintain a complex infrastructure Easier to build on Cardano and developers can get all the data they need for transactions

• Infrastructure-grade: Our API takes the hassle out of maintaining your own computing and storage resources, reducing barriers to entry for developers and businesses.
• Built for developers: Easy-to-read documentation and resources to help developers get started quickly.
• Get App Insights: The dashboard provides insights on API usage.
• Standard Interface: Supports Mainnet and Testnet via client-compatible REST API over HTTP, HTTPS.
• Stay Online: Runs on the latest network upgrades with a 99.9% minimum uptime guarantee.

Webhook system: The webhook system automatically sends data to the project owner's API endpoint, the system user is configured at the DCOneCrypto website

• Notify App system: Notification system: Developer integrates our webhook and SDK. Get access to all blockchain events like successful transaction, payment…
• Webhooks: Let your users know when transaction activity occurs on their wallet address over the user endpoint API connection.
• Monitoring and debugging: We keep a log of all your enabled user webhooks that can monitor their delivery to various endpoints

Development experience: Give users a developer experience, the ability to test and test their webhook.

[IMPACT] Please describe how your proposed solution will address the Challenge that you have submitted it in.

Our project helps the Cardano ecosystem to increase developers productivity. Our APIs, SDKs to power products:

• DeFi Apps,

• Decentralized Exchange,

• NFT Marketplaces.

• DAO

• Data platforms and blockchain explorers.

  [IMPACT] What are the main risks that could prevent you from delivering the project successfully and please explain how you will mitigate each risk?

Risk: These are architectural patterns and technologies used in microservices system, REST API, HA proxy, Event-driven architecture, serverless and used across all services deploying

Solution: running 2 servers in 2 different countries at the same time, always have recovery system to ensure a minimum 99.9% uptime.

[FEASIBILITY] Please provide a detailed plan, including timeline and key milestones for delivering your proposal.

DCOne Crypto is a long-term plan, including building an DCOne website for project owners & users. In the long term, it is possible to consider issuing a project governance token, collecting user fees to maintain and develop the project.

Total implementation time for this proposal: 3 months

Detailed plan and timeline:

The 1st month: REST API, WCF Wallet Blockchain Cardano:

• GET Query Chain: Get the tip info about the latest block seen by chain
• GET Epoch Information: Get the epoch information, all epochs if no epoch specified
• GET address details: Including balance and assets
• GET utxos address: Asset included
• SUBMIT transactions: transactions on the blockchain system
• GET Wallet Stakes: Total stakes, total rewards, available withdrawals
• GET Pool metadata: pool id, url, name, description, etc.
• GET utxos transaction: utxos input/output
• GET Transaction Information: Information like: size, fees, ADA and quantity of assets etc.
• GET Asset: Policy, name, quantity…, etc.
• We also provide more endpoint APIs on the Cardano blockchain and more…

The 2nd month: REST API, WCF Notifications Webhook, Telegram and Discord groups:

• Transactions: get notified about every new transaction
• Payments: receive notifications of new payments filtered by user settings rules
• User admin dashboard with analytics:
• Notifications: handle all system-provided Webhooks, CRUD functions.
• Monitoring: Store logs of your actions at the webhook, API end

The 3rd month: REST API, WCF Expansion of payment utility, system integration, app application

• Javascript SDK
• C# SDK
• iOS SDK
• Android SDK
• SDK Payment, Chart, Price coin on Cardano Blockchain
• Firebase Cloud Messaging (FCM)
• Push Notification service IOS, Android
• Management system for Users

All of the features above here will be available on both the Mainnet and the Testnet.

[FEASIBILITY] Please provide a detailed budget breakdown.

Technical Project Lead: $3500/month * 3 months= $10500

Full-stack Developer: $2500/month * 3 months = $7500

DevOps/ System: $2200/month * 3 months = $6600

Developer IOS, Android: $3000/month * 3 months = $9000

System infrastructure, Disaster recovery capabilities, Security: $2000 x 3 month = $6000

Marketing expense: $1000/campaign * 3 campaigns = $3000

Reserve cost: $2500

Total cost: $45100

[FEASIBILITY] If you are funded, will you return to Catalyst in a later round for further funding? Please explain why / why not.

Yes because DCOne Crypto is a long-term project. We need funds to develop more features to the developers, project owners and users.

If we do not get funding from Catalyst, we will continue to implement our project as we are doing, but the progress will be slower.

[AUDITABILITY] Please describe what you will measure to track your project's progress, and how will you measure these?

We will follow the detailed plan as above. The KPIs for our project are as follows:

• The data access volume in the DCOne Crypto library for SDK, API, Webhook
• Number of request to the server
• Number of developers using the DCOne Crypto library

The community can check the completion of the work in the following way

• Direct access to the project website

• Visit the project's github

• Any major updates will be announced on the project's Telegram and Twitter channels

• Communicate directly with the project team through the above channels

  [AUDITABILITY] What does success for this project look like?

The DCOne Crypto for Developers project is considered successful if it successfully builds and tests the available library for developers. The developer community registered to use DCOne Crypto's library up to 1000 people after 3 months. The uptime is more than 99.99%.

[AUDITABILITY] Please provide information on whether this proposal is a continuation of a previously funded project in Catalyst or an entirely new one.

This is a new project
