I'm a very meticulous person when it comes to finance. Yet, I did happen to me but that's once. I hope I don't get to count another incident of that. Luckily for me it was to a contract address I sent the token and it reverted within a few minutes. I held my breath while all that lasted as soon as I realized my mistake.

I bet you, nobody would be happy or comfortable if it happened to them.

I like to crosscheck the first four letters of the address, the middle and then the last four. Other times I just zoom out on the numbers to compare them side by side with the apps I'm sending from and to when I've pasted on the send tab. I truly take my time whenever I'm transacting. The principle of "No hurry in life" should be aptly applied to crypto transactions, honestly.

So far, so good for me. I'm okay doing the check myself and not likely to need a helper.
