Transparent Address (t-address)

A transparent address (starting with "t1" or "t3") works like a standard Bitcoin address. Every transaction to or from it — the amount, sender, and receiver — is permanently visible on the public Zcash blockchain to anyone using a block explorer.

Transparent addresses are useful when transparency is actually wanted, such as a publicly auditable donation address. They're also what most exchanges use by default for deposits and withdrawals.
