Checks if input is correct transaction hash (32 txs)

transaction~isTransactionTxHex(txs, minWeightMagnitude)

| Param | Type | | --- | --- | | txs | string | | minWeightMagnitude | number |

Checks if input is correct transaction txs (1536 txs)

transaction~isAttachedTxHex(txs)

| Param | Type | | --- | --- | | txs | string |
