Sign and Broadcast Transaction

To sign and broadcast a transaction to the Cosmos network, follow these steps:

  1. Prepare unsigned transactions in Base64 encrypted format.

  2. Sign the transaction using your preferred Cosmos signing method.

  3. Broadcast the signed transaction to the Cosmos network by making a POST request to /api/v1/cosmos/{network}/transaction/send.

    Example request (for cosmoshub-4 network):

    curl --request POST \
         --url \
         --header 'accept: application/json' \
         --header 'authorization: Bearer <token>' \
         --header 'content-type: application/json' \
         --data '

    • signedTransaction — signed transaction in Base64 encrypted format which needs to be broadcast to the network.

    Example response:

        "error": null,
        "result": {
            "status": "success",
            "blockId": 18575267,
            "fee": 0.005952,
            "gas": {
                "used": 202947,
                "wanted": 238047
            "transactionHash": "ADD7B2791E1959075D1836D4BCC71ED256CCD724459F9BD8862D85E205075D47"
    • status — transaction status: success, failed.
    • blockId — unique identifier of the block in which the transaction has been included.
    • fee — total fee in ATOM charged for processing the transaction.
    • gas — computational effort required to execute the transaction, measured in gas units.
      • used — amount of gas spent for the transaction.
      • wanted — maximum gas limit that the transaction initiator was willing to consume for the transaction.
    • transactionHash — hash of the transaction.
