Create a new Solana account by submitting a signed transaction.

headers

string

required

The API key created from Altude

Request Body

string

required

The base64-encoded signed transaction to create the account

Build `signedTransaction` (minimum)

Use this right before calling POST /Account/create.

Demo flow only. Never put fee payer private keys in frontend/client code. Keep signer keys on a trusted server-side signer.
