fromBlockstring
toBlockstring
The block number or block hash to search up to
  • latest [default] - the blockchain's most recent block
  • safe - a block validated by the beacon chain
  • finalized - a block confirmed by over two-thirds of validators
  • earliest - the first or genesis block
  • pending - transactions broadcasted but not yet included in a block
topicsarray
