-a start_slot=349485000 \
-a end_slot=349486000 \
-a out=/path/to/your/data

Another example to listen the latest transactions in Ethereum:

scrapy crawl trans.block.solana \
-a providers=https://your.provider.solana \
-a out=/path/to/your/data

Parameters:

• providers: The RPC provider URL for accessing the Solana. If you have multiple providers, separate them with commas. It is recommended that you get providers from blockchain data services, e.g., alchemy.
• start_slot: (optional) The starting slot number for data collection. if not specified, the spider will start from the latest slot.
• end_slot: (optional) The ending slot number for data collection. If not specified, the spider will continuously listen and parse the latest slot data.

-a signature=3AL2h...Nts \ 
-a out=/path/to/your/data
