先日testnetで遊んでたらなぜか検証に失敗するらしいトランザクションができてしまい、ブロードキャストはできないしお金は吸い込まれちゃったしで泣きながら対応した時のお話。
状況

これがいつまで経ってもブロックに取り込まれない
お金吸われちゃって無一文
$ tapyrus-cli listunspent [ ]
メモリプールを探そうにも空っぽ
$ tapyrus-cli getrawmempool [ ]
ブロックに取り込まれていないので getrawtransaction は動かず
$ tapyrus-cli getrawtransaction d194e9097320090b6f8d4a13c1a0f383f959a2c1d6b05b0d2812019f2ed12caa error code: -5 error message: No such mempool or blockchain transaction. Use gettransaction for wallet transactions.
言われた通り gettransaction して hexstring を入手し
$ tapyrus-cli gettransaction d194e9097320090b6f8d4a13c1a0f383f959a2c1d6b05b0d2812019f2ed12caa { "token": "TPC", "amount": 0.00000000, "fee": -0.00000258, "confirmations": 0, "trusted": false, "txid": "d194e9097320090b6f8d4a13c1a0f383f959a2c1d6b05b0d2812019f2ed12caa", "walletconflicts": [ ], "time": 1649761148, "timereceived": 1649761148, "bip125-replaceable": "unknown", "details": [ { "address": "4ZvKgQcct4Ec2RLkWHKPXe4NqY8WVjDKy2Gd1vxaXGKCyA2CeNQgA47bKkr8nYtd2LSfCiXm3rndbmX", "category": "receive", "token": "c315e9dced5401fe0ae1caaec69ea382440b0dfdbac7803495b8d58f92fc7d62ac", "amount": 1, "vout": 0 } ], "hex": "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" }
それを手動でブロードキャストしようとするも怒られ

つまり検証の失敗事由は”bad-txns-token-insufficient”
メモリプールでのテスト検証にも失敗し

途方に暮れながらなんとかしてこのトランザクションを破棄するコマンドを探していたらドンピシャのコマンドを見つけた
$ tapyrus-cli help ... == Wallet == abandontransaction "txid" ...
これじゃん
解決
実行してみる
$ tapyrus-cli abandontransaction d194e9097320090b6f8d4a13c1a0f383f959a2c1d6b05b0d2812019f2ed12caa
出力は無し
すると
$ tapyrus-cli listunspent [ { "txid": "3b49b5afb9027dd910007424d59c6cd1ce457ab08edb3b521c75163e6eaef500", "vout": 1, "address": "123iMA5vDJgo89NkTosfKqhQXArL3p1Mcm", "token": "TPC", "amount": 0.99999415, "scriptPubKey": "76a9140b7b790f099e87ea17828b64fc433134ffaa253d88ac", "confirmations": 22, "spendable": true, "solvable": true, "safe": true } ]
帰ってきた😭
ただ何が原因だったのかいまいちよく分からないので再現して原因を探りたい...
