Body
BroadcastTxRequest is the request type for the Cosmos.BroadcastTxRequest RPC method.
tx_bytesstring · byteOptional
tx_bytes is the raw transaction.
modestring · enumOptionalDefault:
BroadcastMode specifies the broadcast mode for the TxCosmos.Broadcast RPC method.
- BROADCAST_MODE_UNSPECIFIED: zero-value for mode ordering
- BROADCAST_MODE_BLOCK: DEPRECATED: use BROADCAST_MODE_SYNC instead, BROADCAST_MODE_BLOCK is not supported by the SDK from v0.47.x onwards.
- BROADCAST_MODE_SYNC: BROADCAST_MODE_SYNC defines a tx broadcasting mode where the client waits for a CheckTx execution response only.
- BROADCAST_MODE_ASYNC: BROADCAST_MODE_ASYNC defines a tx broadcasting mode where the client returns immediately.

Path parameters
heightstring · int64Required
height is the height of the block to query.
Query parameters
pagination.keystring · byteOptional
key is a value returned in PageResponse.next_key to begin querying the next page most efficiently. Only one of offset or key should be set.
pagination.offsetstring · uint64Optional
offset is a numeric offset that can be used when key is unavailable. It is less efficient than using key. Only one of offset or key should be set.
pagination.limitstring · uint64Optional
limit is the total number of results to be returned in the result page. If left empty it will default to a value to be set by each app.
pagination.count_totalbooleanOptional
count_total is set to true to indicate that the result set should include a count of the total number of items available for pagination in UIs. count_total is only respected when offset is used. It is ignored when key is set.
pagination.reversebooleanOptional
reverse is set to true if results are to be returned in the descending order.
