testmempoolaccept ["rawtx",...] ( maxfeerate )

Returns result of mempool acceptance tests indicating if raw transaction (serialized, hex-encoded) would be accepted by mempool.

This checks if the transaction violates the consensus or policy rules.

See sendrawtransaction call.

Arguments:
1. rawtxs          (json array, required) An array of hex strings of raw transactions.
                   Length must be one for now.
     [
       "rawtx",    (string)
       ...
     ]
2. maxfeerate      (numeric or string, optional, default=0.10) Reject transactions whose fee rate is higher than the specified value, expressed in SYS/kB
                   

Result:
[                               (json array) The result of the mempool acceptance test for each raw transaction in the input array.
                                Length is exactly one for now.
  {                             (json object)
    "txid" : "hex",             (string) The transaction hash in hex
    "wtxid" : "hex",            (string) The transaction witness hash in hex
    "allowed" : true|false,     (boolean) If the mempool allows this tx to be inserted
    "vsize" : n,                (numeric) Virtual transaction size as defined in BIP 141. This is different from actual serialized size for witness transactions as witness data is discounted (only present when 'allowed' is true)
    "fees" : {                  (json object) Transaction fees (only present if 'allowed' is true)
      "base" : n                (numeric) transaction fee in SYS
    },
    "reject-reason" : "str"     (string) Rejection string (only present when 'allowed' is false)
  },
  ...
]

Examples:

Create a transaction
> syscoin-cli createrawtransaction "[{\"txid\" : \"mytxid\",\"vout\":0}]" "{\"myaddress\":0.01}"
Sign the transaction, and get back the hex
> syscoin-cli signrawtransactionwithwallet "myhex"

Test acceptance of the transaction (signed hex)
> syscoin-cli testmempoolaccept '["signedhex"]'
