The block endpoint returns block id / prev / timestamp nested under a
"header" object with camelCase keys (blockId, dcId, prevId, prevProof,
timestamp) and a proof of just {proof}. The previous flat snake_case
Block fields never matched the response and always deserialized empty.
Add a BlockHeader dataclass, nest it in Block, make proof.scheme
optional, and cover it with a unit test. Verified live against a dev
chain.

Example — fire and forget (most use cases)::
|
|
|
|
from prime_sdk import DragonchainSDK, TransactionCreateRequest
|
|
|
|
client = DragonchainSDK(
|
|
"your-public-id",
|

"your-auth-key",

|
"https://your-dragonchain-endpoint.com",

|
|
|
|
resp = client.transaction.create(
|
|
TransactionCreateRequest(
|
|
txn_type="my-transaction-type",
|
|
payload='{"message": "Hello Dragonchain"}',
|
|
)
|
|
)
|
|
print("Transaction ID:", resp.transaction_id)

# Done — no need to wait for a block.
|
|
|
|
Example — wait for block inclusion (interchain / Daria)::
|
|
|
|
import time
|
|
|
|
resp = client.transaction.create(
|
|
TransactionCreateRequest(
|

if txn.header.block_id:
