Current behaviour
Some Segwit Version 1 Addresses generated with Achow101’s Rust-Vanitygen, or more generally some random Addresses imported using the tr(<WIF Private Key>) Descriptor, cause an issue when spending coins using them. Generally, the “Signing transaction failed” error occurs and the transaction is not created. Though, a workaround still allows to spend the coins.
I don’t know if the issue is exclusive to P2TR, but never encountered such problems with Vanity Version 0 Addresses in the past… I also did not encounter such issue with P2TR Addresses directly generated in Bitcoin Core with getnewaddress or so.
Maybe it is the same issue as #5828, which was however not been reported with a concrete and reproducible example, and was closed since long… If so, then it would mean that other Address Types may be affected as TapRoot did not exist at this time. I have not found other duplicates, but sorry if I missed one…
Expected behaviour
Being able to spend using these Addresses without workarounds.
Steps to reproduce
- Optional: Generate a Vanity P2TR Address with the Achow101’s Rust-Vanitygen, modding it or converting the Private Key from Mainnet to Testnet if necessary. Or simply some random WIF Private Key. Some Addresses will work, others exhibit the present issue… It seems that there is a significant proportion falling in the second case…
- For convenience, you can simply use this one made for this Bug Report:
0internal_privkey: cNKAo2ZRsaWKcP481cEfj3astPyBrfq56JBtLeRhHUvTSuk2z4MR
1internal_pubkey: ac414af4b822d67307fe81bef0a72ddf0be9e6ff129eb1270b1168126f619619
2Address: tb1ptestamfzz5zguhrad6xuf7afua0csz5m6k2qclpnpkvsl20t856sxz2d89
- Import the Address, for example in Testnet4 via the Bitcoin-Qt Console:
0importdescriptors '[{"desc": "tr(cNKAo2ZRsaWKcP481cEfj3astPyBrfq56JBtLeRhHUvTSuk2z4MR)#vhsk8sfh", "timestamp":0}]'
- Optional: get some coins from a Testnet4 Faucet (or any other source) for this tb1ptestamfzz5zguhrad6xuf7afua0csz5m6k2qclpnpkvsl20t856sxz2d89 Address. When I submitted the Issue, there were some coins left…
- Optional: Send some amount involving this Address. Immediately after importing the Address, it appears that there is no particular issue. See Transaction a301d660523de70542d30490052f9e04ba3f9b5e26482745c7dbdc952802f103.
- Restart Bitcoin Core, and try sending again some amount. The interface now shows a “Signing transaction failed” dialog followed by “Transaction creation failed!”. Or, in the Console,
0sendtoaddress tb1qn9rvr53m7qvrpysx48svuxsgahs88xfsskx367 0.0001
1Signing transaction failed (code -6)
- However, if a new Wallet is created, and the Descriptor is imported again as above, sending coins is possible again (until Bitcoin Core is restarted again). The process can be repeated to further reuse the Address (which is obviously not practical).
