Manifold extension for dynamic URIs

DynamicTokenURI is a Manifold extension that enables dynamic token URIs for a Manifold creator contract. Specifically, when a token is transferred between wallets, the URI changes. Foundry is used to build, test, and deploy the contract.

Build

$ forge install
$ forge build
$ forge test
$ forge fmt

Deploy

$ forge create --rpc-url <rpc_url> \
               --private-key <private_key> \
               --etherscan-api-key <etherscan_api_key> \
               -- verify \
               DynamicTokenURI

Then call setExtensionConfig() to configure the following parameters for a creator contract:

• baseURI: base URI to be used for all tokens minted by the extension
• maxSupply: the number of artworks and also the maximum number of tokens to be minted by the extension
• mintCost: the cost of minting. Can be zero.

Once the extension is deployed, it can be registered in the creator contract by calling registerExtension() in the creator contract.

Configure token URIs

By default it is assumed that the metadata directory follows a specific structure:

.
└──<baseURI>
   ├── 1.json
   ├── 2.json
   ├── ...
   └── <maxSupply>.json

eg., the token URI for a token without any transfers will be ${baseURI}1.json, the token URI for a token with a single transfer will be ${baseURI}2.json, etc.

In case the metadata files are not named after numbers indexed from 1 up to the maximum supply of artworks, setTokenURIs() can be called on the extension to map the numbers to fully qualified token URIs, eg., setTokenURIs(creatorContract,[1,2,..],["ar://bla420", "ar://bla69",...]) will force tokens without a transfer to point to "ar://bla420", tokens with a single transfer to point to "ar://bla69", etc.
