simulaterawtransaction

simulaterawtransaction ( ["rawtx",...] {"include_watchonly":bool,...} ) Calculate the balance change resulting in the signing and broadcasting of the given transaction(s). Arguments: 1. rawtxs (json array, optional) An array of hex strings of raw transactions. [ "rawtx", (string) ... ] 2. options (json object, optional) Options object that can be used to pass named arguments, listed below. Named Arguments: include_watchonly (boolean, optional, default=true for watch-only wallets, otherwise false) Whether to include watch-only addresses (see RPC importaddress) Result: { (json object) "balance_change" : n (numeric) The wallet balance change (negative means decrease). } Examples: > bitcoin-cli simulaterawtransaction ["myhex"] > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "simulaterawtransaction", "params": [["myhex"]]}' -H 'content-type: application/json' http://127.0.0.1:8332/

Signature

simulaterawtransaction(rawtxs?: array, options?: object) → any
