Which wallets are built deterministically? (Besides Bitcoin Core) Bitcoin Core can be built deterministically, allowing anyone to compile the software themselves and compare it to the released version to see if they're identical.  Presumably, software forks of Bitcoin Core like Bitcoin Knots also provide this capability, and I recall that some people did this also for BIP148 UASF forks of Bitcoin Core.

What other software[1] wallets typically provided in pre-compiled form[2] are deterministically built?  Deterministic builds seem like a powerful and useful security feature, but as far as I know, almost no software wallets besides Bitcoin Core provide that feature.

Note: deterministic builds should not be confused with BIP32 Hierachical Deterministic (HD) wallets.

[1] Some hardware wallets, like Trezor, provide deterministic builds of their firmware, which is a nice feature.  However, that does nothing to prove the security of the hardware, which is hard to audit with the tools found even in a typical geek's home office.

[2] That is, not provided entirely using interpreted code.
Electrum's distributed binaries are determinisitc. Although Electrum is written in an interpreted language, the distributed binaries also need to provide the dependencies and the packaging process for producing binaries for python software is not deterministic. Electrum has their own process for ensuring dependency versions and determinism of their binaries.

Mycelium's distributed binaries are deterministic built. They use a docker container instead of Gitian to produce their binaries.
