Allora — Networks/Protocols supported, Information, Transactions, ABCI (3/3)

API reference for Allora. All methods ->

Part 3 of 3: 1 · 2 · 3

Transactions​

broadcast_tx_sync​

Returns with the response from CheckTx. Does not wait for DeliverTx result.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See https://docs.cometbft.com/v0.34/core/subscription.html If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

  1. A malicious node drops or pretends it has committed your tx.
  2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future (https://github.com/tendermint/tendermint/issues/3322).

Please refer to Tendermint docs for formatting/encoding rules.

Parameters​


  • tx (string; required): the transaction.

Request example​

curl -X POST https://rpc.ankr.com/allora_testnet/YOUR_ANKR_API_KEY \
-H 'Content-Type: application/json' \
-d '{
      "jsonrpc": "2.0",
      "method": "broadcast_tx_sync",
      "params": ["456"],
      "id": 1
    }'

Response example​

{
  "jsonrpc": "2.0",
  "id": 0,
  "result": {
    "code": "0",
    "data": "",
    "log": "",
    "codespace": "ibc",
    "hash": "0D33F2F03A5234F38706E43004489E061AC40A2E"
  },
  "error": ""
}

broadcast_tx_async​

Returns right away, with no response. Does not wait for CheckTx nor DeliverTx results.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See https://docs.cometbft.com/v0.34/core/subscription.html If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

  1. A malicious node drops or pretends it has committed your tx.
  2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future (https://github.com/tendermint/tendermint/issues/3322).
  3. A node is offline.

Please refer to CometBFT docs for formatting/encoding rules.

Parameters​


  • tx (string; required): the transaction.

Request example​

curl -X POST https://rpc.ankr.com/allora_testnet/YOUR_ANKR_API_KEY \
-H 'Content-Type: application/json' \
-d '{
      "jsonrpc": "2.0",
      "method": "broadcast_tx_async",
      "params": ["123"],
      "id": 1
    }'

Response example​

{
  "jsonrpc": "2.0",
  "id": 0,
  "result": {
    "code": "0",
    "data": "",
    "log": "",
    "codespace": "ibc",
    "hash": "0D33F2F03A5234F38706E43004489E061AC40A2E"
  },
  "error": ""
}

broadcast_tx_commit​

Returns with the responses from CheckTx and DeliverTx.

warning

Use only for testing and development. In production, use BroadcastTxSync or BroadcastTxAsync. You can subscribe for the transaction result using JSON-RPC via a websocket (see CometBFT docs).

tip

CONTRACT: only returns error if mempool.CheckTx() errs or if we timeout waiting for tx to commit. If CheckTx or DeliverTx fails, no error will be returned, but the result will contain a non-OK ABCI code. Please refer to CometBFT docs for formatting/encoding rules.

Parameters​


  • tx (string; required): the transaction.

Request example​

curl -X POST https://rpc.ankr.com/allora_testnet/YOUR_ANKR_API_KEY \
-H 'Content-Type: application/json' \
-d '{
      "jsonrpc": "2.0",
      "method": "broadcast_tx_commit",
      "params": ["785"],
      "id": 1
    }'

Response example​

check_tx​

Checks the transaction without executing it.

The transaction won't be added to the mempool.

Please refer to CometBFT docs for formatting/encoding rules.
