I’ve been trying to figure out how to sign a raw Stellar transaction so that I can perform operations other than transfer. I used the Stellar SDK to construct a transaction and convert it to a raw XDR byte buffer. I then attempted to use createTransaction from Fireblocks SDK, but it fails with HTTP status 400 and data { message: 'Invalid message content (undefined)', code: 1409 }
.
Here’s some relevant data from the request that I logged from axios. Anything seem out of place about it?
baseURL: 'https://sandbox-api.fireblocks.io',
method: 'post',
url: '/v1/transactions',
