The code seems to do what is intended and I confirm that it works. I guess it is useful as a generic tool to create a new transaction and two new children of it that have the same txid and different wtxid.

That is useful for the tests of https://github.com/bitcoin/bitcoin/pull/29415 too. However those tests already have a transaction and it would be easier for them and less code, if `malleate_tx()` could create a malleated/changed version of an

The name `build_malleated_children` might be confusing since there is nothing "malleated" in those transactions. They are created as such and never [changed or malleated](https://en.bitcoin.it/wiki/Transaction_malleability) afterwards.

Also in the name of `ValidWitnessMalleatedTx`.

This works! Following the hint from https://github.com/bitcoin/bitcoin/pull/29415#discussion_r2160767733 I could integrate it into the tests of https://github.com/bitcoin/bitcoin/pull/29415 to try to send two transactions that have the same txid and different wtxid.

However using it is a bit involved - one has to create a new dedicated parent transaction, get it in the mempool and then broadcast the two children. Also, one has to handle the fees manually. Like this:

```py
self.log.info("S

Thanks for taking my suggestion @willcl-ark

Your modified string is even better!

Just a couple of comments and then I will re-test again.

nit: use `fs::quoted` here and other places, will avoid the slashes?

Having a constructor here will prevent the C.I failure I think, emplace_back will forward the values to constructor which is missing now.

@andrewtoth, right! I will change that next time I retouch, "resolving" this.

Accepted @vasild's patch.

> Note that `bitcoin-qt` is linked against some dynamic libraries inside `depends/` so it will not work if moved to another machine without those libraries. Is this expected?

No, it is not. This should be fixed in a follow up.

Considering the commit history of the NixOS [patch](https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/cm/cmake/001-search-path.diff), it seems it was required for some packages, but perhaps it’s no longer needed.

On the other hand, the CMake documentation [states](https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_PREFIX_PATH.html):

(https://github.com/bitcoin/bitcoin/pull/32631#pullrequestreview-2949718938)
I think the changes here can be simplified quite a bit by first replacing `get_iter_from_wtxid` with a `GetIter(const wtxid&)` overload, see my suggestions here and here (or full branch https://github.com/bitcoin/bitcoin/compare/master...stickies-v:bitcoin:2025-06/overload-getiter).

There are also quite a few clang-tidy violations that would be helpful to address here, left per-commit comments.
