When you submit a malformed transaction to Horizon, Horizon will return a transaction_malformed error. There are many ways in which a transaction is malformed, including
- you submitted an empty string
- your base64-encoded string is invalid
- your XDR structure is invalid
- you have leftover bytes in your XDR structure
If you are encountering this error, please check the contents of the transaction you are submitting. This error is similar to the Bad Request error response and, therefore, the HTTP 400 Error.
