Previewnet test network

Previewnet is a public test network running the upgrade-7 feature set ahead of the other networks. It has allowed builders and integrators to experiment with both the EVM and Michelson interfaces and with cross-interface interactions ahead of the upgrade 7 on Mainnet.

Resources

The previewnet repository contains network parameters, configuration, and up-to-date endpoint information:

Connecting

The previewnet exposes two RPC endpoints — one per interface:

• EVM Interface RPC — compatible with Ethereum JSON-RPC. Connect using MetaMask, ethers.js, viem, or any Ethereum toolchain by pointing to this endpoint.
• Michelson Interface RPC — compatible with the Tezos RPC standard. Connect using Octez, Temple wallet, Taquito, or any Tezos toolchain by pointing to this endpoint.

See the previewnet repository for the current endpoint URLs.

Getting tez

A faucet is available from the previewnet explorer linked in the repository. Tez obtained on the testnet has no real-world value.

Block explorer

The previewnet ships with an explorer covering both interfaces. The explorer aggregates information from both the EVM and Michelson interface blocks and can display cross-interface call graphs.
