According to the default implementation, only protocol owners can accept propositions to the underlying assets (in ipfs), and only the current owner of the NFT can accept the upgrades. Currently we support ERC721 and Factory contracts (Collections) which can be added through the Dapp UI. Propositions and Collections are stored on Ceramic. 38 | We also have deployed a default DynamicFactory for minting assets that get their metaata automatically pinned on IPFS. 39 | The main purpose of the DAPP is to allow protocols to have an Upgradability UX out-of-the-box. This allows new protocols extending the dyNFT contracts to have an easy and user friendly way of upgrading the assets of their NFTs. 40 | 41 | ### Use cases : 42 | - New GameFi protocols. 43 | - Collectibles with Mutation/Upgrades logic. 44 | - Insurance Policies. 45 | - Oracle based Dynamic NFTs. 46 | - All the other use cases of non-static NFTs 47 | 48 | 49 | ### Architecture: 50 | - Smart Contract Development: [Hardhat](https://hardhat.org/) 51 | - Data Layer: [Ceramic](https://ceramic.network/) 52 | - Decentralized File Storage : [IPFS](https://ipfs.io/) 53 | - Frontend : [Svelte](https://svelte.dev/) 54 | - Interaction with Ehtereum : [ethers.js](https://docs.ethers.io/v5/) 55 | - Crypto wallet : [Metamask](https://metamask.io/) 56 | 57 | ![Dynamic NFTs Architecture](./presentation/images/architecture.png) 58 | 59 | 60 | ## Directory Structure 61 | - `client`: Project's Svelte dapp frontend. 62 | - `server`: Project's backend. 63 | - `dynamic-nfts`: Smart contracts that are deployed in the Polygon Mumbai testnet. 64 | - `dynamic-nfts/contracts`: Smart contracts showing example implementations. 65 | - `dynamic-nfts/contracts/lib`: The Smart contracts library. 66 | - `dynamic-nfts`: Smart contracts that are deployed in the Polygon Mumbai testnet. 67 | - `dynamic-nfts/deploy`: Deployment Scripts. 68 | - `dynamic-nfts/test`: Tests for smart contracts. 69 | 70 | 71 | ## Installation 72 | 73 | Clone & Run: 74 | 75 | ``` 76 | git submodule init 77 | git submodule update 78 | ``` 79 | 80 | ### Prerequisites 81 | 82 | - Install [Node.js >= v14](https://nodejs.org/en/download/) 83 | - Yarn / Npm 84 | - Install [MetaMask](https://metamask.io/) extension in your browser 85 | 86 | ### Frontend 87 | 88 | - `cd server` 89 | - `yarn install` 90 | - `yarn start` 91 | - Started at `http://localhost:{env.PORT}` 92 | 93 | ### Server 94 | 95 | - `cd client` 96 | - `yarn install` 97 | - `yarn start` 98 | - Open `http://localhost:3000` 99 | 100 | ### Running Tests: 101 | 102 | ``` 103 | cd dynamic-nfts 104 | yarn install 105 | ``` 106 | 107 | Start `ganache-cli` at 8545 & 108 | 109 | ``` 110 | yarn test 111 | ``` 112 | 113 | ## Environment variables 114 | `Dapp :` 115 | ``` 116 | VITE_NFT_STORAGE_KEY= 117 | VITE_NFT_PORT_KEY= 118 | VITE_API_URL= 119 | ``` 120 | `Server :` 121 | ``` 122 | SEED= 123 | PORT= 124 | CERAMIC_API_URL= 125 | NFT_STORAGE_KEY= 126 | ``` 127 | `NFTs Contracts :` 128 | ``` 129 | RPC_URL= 130 | RPC_URL_TEST= 131 | PRIVATE_KEY= 132 | NFT_STORAGE_KEY= 133 | ``` 134 | 135 | ## TODO features 136 | 137 | - Refactor Contracts 138 | - Add Royalty Support 139 | -------------------------------------------------------------------------------- /avoiding_common_attacks.md: -------------------------------------------------------------------------------- 1 | # Contract security measures 2 | 3 | ### SWC-103 (Floating pragma) 4 | 5 | Specific compiler pragma `0.8.10` used in contracts to avoid accidental bug inclusion through outdated compiler versions. 6 | 7 | ### Reentrancy (even tho it can't happen withou an untrusted call) - state changes before external calls. 8 | 9 | ### No overflow and underflow because solv > 0.8.0 --> SafeMath. 10 | 11 | ### OpenZeppelin Ownable implementation. 12 | -------------------------------------------------------------------------------- /checklist.txt: -------------------------------------------------------------------------------- 1 | https://github.com/indeavr/blockchain-developer-bootcamp-final-project 2 | 3 | Please answer the following questions.
