Accounts and addresses

Accounts

Tezos uses these types of accounts:

• User accounts (sometimes known as implicit accounts) store tez (ꜩ) and tickets. Any wallet application or the Octez command-line tool can create user accounts.

• Smart contract accounts (sometimes known as originated accounts) store immutable code, mutable storage, tez (ꜩ), and tickets. See Smart contracts.

Revealing accounts

User accounts are unrevealed until they make a transaction. They can store tez and tickets, but some services such as indexers may not see them.

To reveal an account, send any transaction from it, such as calling a smart contract or sending tez to any account, including itself.

Addresses

• User accounts have addresses that start with "tz1", "tz2", "tz3" or "tz4."

• Smart contracts have addresses that start with "KT1."

• Smart Rollups have addresses, but are not accounts because they cannot store tez. Their addresses start with "sr1". They have a tree of commitments attached to them. See Smart Optimistic Rollups.
