https://blockstream.info/ I suggest you (as other above) to add more details on bitcoin explorers. Which ones suport Segwit address should be categorised, and differentiated from explorer that don't support Segwit addresses (like blockchain.com).
Furthermore, I don't think you should add information of other alts, LTC, Doge, DASH, whatever (kind of distraction), because this topic is only for bitcoin transaction. Hence, you should stick with bitcoin only.
