AML check on Tezos

Tezos is a proof-of-stake blockchain with the native coin XTZ (tez). User addresses start with tz1 to tz4; addresses starting with KT1 are smart contracts.

Address formatUser accounts start with tz1–tz4, smart contracts with KT1 · 36 characters, Base58Checktz1sNNxqmQHeweBRA9wCvighujdFjzgiWp3nExample for illustration, not a real address.
Note

Delegating tez to a baker is not a transfer, because the coins stay under the owner's control. When a check returns a KT1 address, you are looking at a smart contract, such as a token or app, not a personal wallet.

How to check a Tezos address

  1. Get the public addressAsk your counterparty for the address they will send from — or copy it from the incoming transaction.
  2. Pick a service that covers TezosChoose one marked “Supported” in the list above. Before you run a check, make sure the address starts with tz1, tz2, tz3, tz4 or KT1 and is 36 characters long. A KT1 result describes a smart contract, not a person.
  3. Run the check and read itFor USDT on Tezos, check the tz address that holds the tokens. The token itself lives in Tether's contract KT1XnTn74bUtxHfDtBmm2bGZAQfhPbvKWR8o (token ID 0), which is not the counterparty.
A real AML check needs only a public address. Never share a seed phrase or private key.

Tezos specifics

  • Tezos blocks are produced by 'bakers', who temporarily stake tez as a security deposit and need at least 6,000 tez of baking power to be allowed to bake.[1]
  • Delegating tez to a baker does not move the coins: according to the official docs you keep full control of the tez and can spend it at any time, and you are not penalised if the baker misbehaves.[2]
  • Staking is different from delegating: staked tez stays in the owner's account but cannot be transferred, can be penalised along with the baker's deposit, and becomes available again only after a delay of about 4 days once unstaked.[3]
  • Tezos upgrades itself through a built-in on-chain process: bakers propose and vote on protocol changes over 5 periods, and approved upgrades activate automatically without a hard fork.[4]
  • Etherlink is built on Tezos Smart Rollups and lets applications originally written for Ethereum (EVM apps) run on Tezos; Smart Rollup addresses start with sr1.[5]

FAQ

Does delegating my tez to a baker move my funds?

No. The official Tezos docs say delegated tez stays under your full control and you can spend it at any time. Staking is different: staked tez stays in your account but is locked and can be penalised if the baker misbehaves.

What is the difference between tz and KT1 addresses?

Addresses starting with tz1, tz2, tz3 or tz4 are user accounts, and the number shows which signature scheme the account uses. Addresses starting with KT1 are smart contracts: programmable accounts with their own code and storage.

Is there USDT or USDC on Tezos?

Tether lists Tezos as a supported network for USDT, issued through the contract KT1XnTn74bUtxHfDtBmm2bGZAQfhPbvKWR8o with token ID 0. Circle's list of networks with native USDC does not include Tezos.

How do I check a Tezos address for AML risk?

Copy the public address, open one of the services listed above that supports Tezos, and run the check. You never need a seed phrase or private key.

What does “Not verified” mean?

The service claims support somewhere — in marketing copy or a third-party page — but its own docs, pricing or FAQ do not list the network. Treat it as unknown.
