Arguments: 1. txid (string, required) The transaction id (must be in mempool) 2. verbose (boolean, optional, default=false) True for a json object, false for array of transaction ids Result (for verbose = false): [ (json array of strings) "transactionid" (string) The transaction id of an in-mempool ancestor transaction ,... ] Result (for verbose = true): { (json object) "transactionid" : { (json object) "size" : 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. "fee" : n, (numeric) transaction fee in BTC (DEPRECATED) "modifiedfee" : n, (numeric) transaction fee with fee deltas used for mining priority (DEPRECATED) "time" : n, (numeric) local time transaction entered pool in seconds since 1 Jan 1970 GMT "height" : n, (numeric) block height when transaction entered pool "descendantcount" : n, (numeric) number of in-mempool descendant transactions (including this one) "descendantsize" : n, (numeric) virtual transaction size of in-mempool descendants (including this one) "descendantfees" : n, (numeric) modified fees (see above) of in-mempool descendants (including this one) (DEPRECATED) "ancestorcount" : n, (numeric) number of in-mempool ancestor transactions (including this one) "ancestorsize" : n, (numeric) virtual transaction size of in-mempool ancestors (including this one) "ancestorfees" : n, (numeric) modified fees (see above) of in-mempool ancestors (including this one) (DEPRECATED) "wtxid" : hash, (string) hash of serialized transaction, including witness data "fees" : { "base" : n, (numeric) transaction fee in BTC "modified" : n, (numeric) transaction fee with fee deltas used for mining priority in BTC "ancestor" : n, (numeric) modified fees (see above) of in-mempool ancestors (including this one) in BTC "descendant" : n, (numeric) modified fees (see above) of in-mempool descendants (including this one) in BTC } "depends" : [ (array) unconfirmed transactions used as inputs for this transaction "transactionid", (string) parent transaction id ... ] "spentby" : [ (array) unconfirmed transactions spending outputs from this transaction "transactionid", (string) child transaction id ... ] "bip125-replaceable" : true|false, (boolean) Whether this transaction could be replaced due to BIP125 (replace-by-fee) }, ... } Examples: > bitcoin-cli getmempoolancestors "mytxid" > curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getmempoolancestors", "params": ["mytxid"] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
