What it means
We validate address format, memo requirements, and rail compatibility at creation time, so an unspendable destination is caught before a user is asked to pay.Common causes
- The address is malformed for the given rail.
- The rail requires a memo and none was supplied.
- The asset is not supported on that rail.
How to resolve
Check the address against therequires_memo and format fields for that rail in GET /rails. Correct the destination and create a new intent.
