Block Explorers

When you use commands like sncast deploy, sncast declare, or sncast account create, sncast will display block explorer links in the output if the network supports it. These links allow you to quickly inspect the transaction, contract, or class on a public block explorer such as Starkscan or Voyager.

💡 Tip If you want to use a specific block explorer, see the block-explorer configuration details.

When Are Explorer Links Shown?

Shown by Default

Public Networks: Explorer links are enabled by default for public networks (e.g., Sepolia, Mainnet) if the tool can detect a supported explorer for the network.

Hidden

Devnet: Explorer links are not shown for localhost or devnet URLs (e.g., http://localhost:5050/rpc or http://127.0.0.1:5050/rpc). This prevents confusion, as local network transactions are not visible in public explorers.

Disabling Explorer Links

You can turn off explorer links by setting show-explorer-links = false in your snfoundry.toml profile. See the snfoundry.toml appendix for details.

Environment Variable Override

It's possible to force explorer links to be shown by setting the environment variable SNCAST_FORCE_SHOW_EXPLORER_LINKS:

$ SNCAST_FORCE_SHOW_EXPLORER_LINKS=1
