At least Boltz understands Bitcoin is not fungible.

Boltz regarding censoring of transactions:


Hi there,
for full transparency: Yes, we do.
For those who want some more detail: We block swaps originating from OFAC blacklisted addresses since quite some time already (see #340280), see also 4.17 in https://boltz.exchange/terms. The goal is simple: avoid our users having their swap funds frozen by entities like European or U.S. exchanges.
But precisely this happened over the past couple of days. Turns out ByBit Hack related funds are moving through different Bitcoin rails and caused funds to be flagged and frozen by different regulated exchanges. To counter this, we added the ByBit blacklist (https://dt074px2e9qbh.cloudfront.net/exploit-api.json) in addition to the OFAC blacklist. Goes without saying, that checks against these lists run locally on our server.
So... we are not blocking Bitcoin originating from coinjoins, but if you are participating in a coinjoin round with blacklisted ByBit Hack addresses, then we do. If you intend to use Boltz with coinjoined funds, it's a good idea to investigate about your coordinator a bit beforehand (see e.g. https://x.com/Ziya_Sadr/status/1904683659686215806).
We'd love to see dramatically improved fungibility on Bitcoin and are looking to implement Payjoins to do our (little) part. Particularly excited about the upcoming v3 multiparty version: https://payjoindevkit.org/2025/03/18/the-evolution-of-payjoin/#looking-to-the-future-payjoin-v3
