How do I lookup the details of a transaction, given the transaction ID? I transferred BTC from GDAX to Binance.  I have the transaction ID.  How do I find out the status of the transfer.  GDAX reports transfer complete.  Thanks.
I found where GDAX shows the transaction hash!


Visit https://www.gdax.com/accounts
Click a coin on the left (BTC, BCH, ETH, or LTC). 
Instead of staying on the "History" tab (which is probably where you see Transfer ID for each transfer), click "Transfers" in the top right.
Then click each "withdraw" row to expand it, and you'll see its transaction hash.


For example, I'm able to find the hash of an LTC that I just transferred, and then I can browse to https://bchain.info/LTC/tx/4a857bc76d31c801dbc1aac33c4940cd11401f7f7401dfd6e05dfcf43af8867e and see that it has already been confirmed twice.
