Question: for exporting chain data I am supposed to provide the first and the last block, so for fetching it can i use this: https://docs.nethermind.io/interacting/json-rpc-ns/eth#eth_getblockbynumber ?

[arnavchhokra]

The relevant function: public ResultWrapper<BlockForRpc> eth_getBlockByNumber(BlockParameter blockParameter, bool returnFullTransactionObjects) { return GetBlock(blockParameter, returnFullTransactionObjects); }
