A tool to view and analyse transactions, blockchain metrics and other data, using the Infura API.
Inspired to some extent by StarkScan and Etherscan.
A basic console program is working. This has been tested on Windows but should also work on Linux and MacOs.

- Develop the StarkExplorerLib library to retrieve more data such as Events and Contracts.
- Develop a GUI to allow easier user access.
- Store retrieved data in a local cache dB and check for local presence before requesting new data.
- Develop analysis functionality: I like the blockchain intelligence concepts and abilities of Chainalysis.
- Develop access to other Blockchains: Infura has access to Ethereum Mainnet, Polygon, Optimism and others.
Stark data is fetched via the Infura Starknet API. I have used a free Infura account that gives
- 1 API key
- 100,000 Total Requests/Day
- 10 Requests/Second
Which is more than enough for my requirements.
An API key is required and should be stored as an environment variable called INFURA_APIKEY on the machine that runs StarknetExplorer. This is so that the key does not have to be stored in a software repository, Github in this case. The app will throw an exception if it cannot find INFURA_APIKEY.
Note that you will need to set access at

Specifically, the Starknet endpoints:
Select MAINNET for Live and/or SEPOLIA for testing.
