Studio Issue Report - <Cannot switch from Testnet to Mainnet on Studio>

Manifold Support

  • Wallet Address: 0x1234…abcd

  • Issue Summary: I am stuck in Testnet mode in Manifold Studio.

  • What I’m trying to do: I want to deploy a new smart contract on Ethereum Mainnet.

  • Actual outcome: Even after connecting a wallet that is set to Ethereum Mainnet (MetaMask), Studio only shows Sepolia (Testnet) as the network and I cannot change it.

  • I disconnected and reconnected the wallet, used incognito mode, and tried multiple browsers (Chrome, Edge), but the problem persists.

  • “Create New Workspace” still defaults to Testnet.

  • No option to switch to Mainnet is visible.

  • Browser: Chrome + Edge (latest versions)

  • Wallet: MetaMask

  • Screenshots: Attached (including Studio stuck on Sepolia)

Please help me force switch to Mainnet or advise what else I can try.

You can switch to your Mainnet by selecting your Mainnet profile. It’s in the Dropdown if you click on your profile on the top right while you’re in Studio.

You’ll see Profiles and subheadings with a testnet workspace and your mainnetwork workspace.
