- [x] Keep it as simple as posible.
## ToDo and wanted features:
- [ ] Integrate CIDStorage library to the Dapp Indexer smart contract
- [ ] Create an event for metadata information about the CID.
- [ ] Support other type of hashes or structure storage
- [ ] Support of the [CID Specification](https://github.com/multiformats/cid?tab=readme-ov-file)

### Enviorment Variables
### Deploy
#### Option1: Deployment script (recommended)
```shell
$ forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>
$ ./deploy.sh
```
> IMPORTANT: verify .env information before executing the deployment script
**verify by attaching the deployed contract test:**
Once you deployed the contract with the previous script execution you can test
the correct smartcontract operations by running the `DeployedDappIndexer.s.sol`
script
should set after deploying the smart contract in the .env named after
DAPPINDEXERADDRS, once you update the address you can run the following
script to verify it was deployed correctly.
```shell
$source .env
$forge script script/DeployedDappIndexer.s.sol:DappIndexerScript --fork-url $PROVIDER_URL --private-key $PK0 --broadcast
```
#### Option2: Script deployment and test
using the script follows diferent verifications first before deploying the
contract, more about it here.
```shell
$source .env
$forge script script/DappIndexer.s.sol:DappIndexerScript --fork-url $PROVIDER_URL --private-key $PK0 --broadcast
```
> where:
> PROVIDER_URL can be either the anvil fork or a blockchain RPC
> $PK0
