Accounts and addresses


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.


  • 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.
