Client for receiving blockchain data through block explorers (in particular, routescan).
At the moment, the number of available methods is limited to those indicated in the examples below:
To support this project, you can send crypto to:

main();You must use the API key of the corresponding block explorer!!!
Just register an account on corresponding site and generate an API key.
PS: Client also support other etherscan-compatible block explorers, but in this case you must provide custom url parameter.
