@e2ccf7cf…26c1c8eb might have one

I don't have a guide, but it would be fun to make one. BE CAREFUL though. You don't want to send real Bitcoin to a testnet address. Have her try a testnet only wallet like Padawan first. I don't know any iPhone testnet apps.🫤 https://github.com/thunderbiscuit/padawan-wallet She can use the seed signer with Nunchuck. Just change the network settings to testnet instead of mainnet. Be sure to change it back when you're done. Let me know if you have any questions or need some testnet 4 sats.

I have a regtest node but I've never actually had a need to use testnet. Lemme look for some good resources to link you. @f728d9e6…c8a38106 may can help here. I don't know the status of testnet3/4 . I know there's been a big hub bub about breaking it a bunch.
