Also can you use a t-address (the shorter one) instead of the z-address?
I'm wondering that too. My Polo deposit address is a T address.
Same here. Anything wrong with the t address? Should that start with the Z or smaller z address?
I was told on the zcash forum that t means "transparent" and z means "hidden" -- so AFAIK t addresses aren't testnet addresses (which is what I had assumed) and can be used for mining real coins on the mainnet.
Don't shoot me if I'm wrong I'm just relaying what I was told.
