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 JSONRPC via a websocket. See https://docs.tendermint.com/v0.34/app-dev/subscribing-to-events-via-websocket.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

JSON-RPC

curl -X POST https://rpc.ankr.com/sei/YOUR_ANKR_API_KEY \
-H 'Content-Type: application/json' \

  },
  "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 JSONRPC via a websocket. See https://docs.tendermint.com/v0.34/app-dev/subscribing-to-events-via-websocket.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 Tendermint docs for formatting/encoding rules.

Parameters

• tx (string; required): the transaction.

JSON-RPC

  },
  "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 JSONRPC via a websocket (see Tendermint 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 Tendermint docs for formatting/encoding rules.

Parameters

• tx (string; required): the transaction.
