# Development Catalogue

This is a wiki page of current projects and potential project ideas divided into sections. Feel free to add links to existing projects and more ideas.

The potential projects (specifically ones with [ ] checkbox) can be used for grant applications [here](https://near.org/grants).

## Art / Collectible Marketplaces

> Marketplaces for art and collectible digital or physical items.

- 🚀 [Paras](https://paras.id) - Digital Card Marketplace - [codebase](https://github.com/ParasHQ)
- 👷 [Mintbase](https://mintbase.io/) - NFT Marketplace Factory - [codebase](https://github.com/Mintbase)
- [Apply for grant for NFT project](https://grants.near.org/submit/187088/near-startup-grants)
- Apply for Art*NFT project funding via [Createbase](http://createbase.community/) [grants](https://www.notion.so/Createbase-Application-form-d9bee851784f45caafd4c1c84af0586c)

## Other marketplaces

- 🚀 [TessaB](https://tessab.com) - Reinvent Mobile Device Ownership

Ideas:
- [ ] Decentralized crowdsourcing platform (aka Mechanical Turk)

## Games

> Games and related services either using or fully on blockchain.

- 🚀 [Berry Club](https://berryclub.io) - Crowd-drawing and farming berries - [codebase](https://github.com/evgenykuzyakov/berryclub)
- 🚀 [Zed Run](https://picks.playwithzest.com/) - Own. Race. Earn.

Ideas:
- [ ] Game NFT creator: an application to create a set of NFTs for game, payment token and just expose APIs for game developers to interface with.
- [Apply for grant to build a game or game related services on NEAR](https://grants.near.org/submit/187088/near-startup-grants)

## Social

Ideas:
- [ ] Token factory UI to create social tokens for people and communities
- [ ] Bots that integrate tokens and DAOs into social channels: Telegram, Slack, Discord
- [ ] Encrypted content sharing between people.
- [ ] Photo and video sharing service aka "NearGram". Images are stored in decentralized storage, on chain just identity + latest image hash.
- [ ] Decentralized review app. Based on review protocol that encompasses some form of sybil resistance (reputation). Review protocol can include reviewing anything that is blockchain indexable, starting with collecting reviews for other on-chain projects and NFTs. Review itself stored in decentralized storage, storing on-chain reputation and interactions.
- [ ] Signal-like private instant messenger that uses on-chain identity, integrates with payments and DAOs naturally. Doesn't use phone numbers and central server for discovery. For example, can be forked from Telegram open source UI and just add alterantive login / discovery protocols and extra features.

Many of these apps require integrations with storage, see "Developer Tools" section. Also they would benefit from having gateways like Ads gateway.
