Tutorials

Hands-on walkthroughs that take you from "what is Tezos X?" to working code on the Previewnet.

Every tutorial is written so you can copy-paste, run, and verify the result in an explorer. They assume you've already skimmed the Overview and have a wallet ready (MetaMask for the EVM interface, Temple for the Michelson interface — see Wallet support).

Available tutorials

• Cross-interface counter — Build a counter whose state lives on the Michelson interface but is incremented and decremented from a Solidity contract on the EVM interface. The whole call chain runs in a single atomic transaction. Good first contact with Native Atomic Composability: you'll see a real callMichelson go through the gateway, follow the result in both block explorers, and trigger an atomic revert to confirm the failure semantics.

More tutorials are on the way — check back, or open an issue at gitlab.com/tezos/xdocs if there's a specific scenario you'd like covered.

For live, hosted demos and example dApps, see the Previewnet dashboard — it lists the showcase apps currently running on the network (Pot(z)luck, xDex, …).
