This is what we currently have:

// Boltz standard JSON refund swap file. Can be used to create a file that can be uploaded to boltz.exchange
#[derive(Serialize, Deserialize, Debug, Clone)]
pub struct RefundSwapFile {
    pub id: String,
    pub currency: String,
    pub redeem_script: String,
    pub private_key: String,
    pub timeout_block_height: u32,
}
impl RefundSwapFile {
    pub fn file_name(&self) -> String {
        format!("boltz-{}.json", self.id)
    }
    pub fn write_to_file<P: AsRef<Path>>(&self, path: P) -> Result<(), Error> {
        let mut full_path = PathBuf::from(path.as_ref());
        full_path.push(self.file_name());
        let mut file = File::create(&full_path)?;
        let json = serde_json::to_string_pretty(self)?;
        writeln!(file, "{}", json)?;
        Ok(())
    }
    pub fn read_from_file<P: AsRef<Path>>(path: P) -> Result<Self, Error> {
        let mut file = File::open(path)?;
        let mut contents = String::new();
        file.read_to_string(&mut contents)?;
        Ok(serde_json::from_str(&contents)?)
    }
}

additional information that would really help wallet users is key derivation paths used; it would deviate from the standard but they can be optional fields.
