Midnight contract deployment fails on
Original: Why your Midnight contract "can't be found on chain" (or: Midnight, stop playing with my emotions)
Short summary
A developer discovers old Midnight tutorials reference a deprecated testnet-02 network that no longer exists, causing contract deployment failures. Key issues: networks are separate (local, preprod, mainnet), test tokens require explicit registration to generate gas fees, and wallet configuration must match network selection. A debugging checklist prevents silent deployment failures.
- •Old Midnight tutorials point to retired testnet-02 — verify current network configuration in code
- •NIGHT tokens must be registered to generate DUST gas fees; holding unregistered NIGHT fails silently
- •Wallet must be set to correct network (Preprod vs mainnet) before copying addresses for faucet requests
