Interesting. Who would these two be custodians for? Bitgo, coinbase, fortress, etc are more commonly known, at least to me.
I've always maintained that our corn is best kept in our own personal corn barns but I'm also keen to keep up to date and understand what the financialisation of it, despite being anathema to me, will do to Bitcoin. I've never even heard of a lot of the institutions who are involved. At the same time that I'm doggedly sticking to my principles, I do think that being aware of who is becoming involved in Bitcoin and how legacy institutions and regulators are looking to treat it is useful in helping me not be shocked if things get weird. Since 2011 I've done my best to keep my obsession with Bitcoin in check but I just want to know as much as possible, the good and the bad. How many of you know https://copper.co or https://www.komainu.com ? While they look like they do involve with shatcoins it's probably wise to know who is going to be custodying the corn that institutions/ETFs are invested in. I've had exactly zero response on nostr to questions about details about these ETFs which either suggests most of us just don't give a fuck or, more likely, I'm just too boringš„³. Anyway, I quite enjoy writing pseudo intellectual notes and posting them so I'll leave it at that.
Discussion
As far as I can see copper are UK based so maybe more involved with the European institutions while Komainu are part of Nomura which is likely big in Asia but I wouldn't want to say that they are restricted to their respective geographies.
The Jacobi FT Wilshire Bitcoin ETF for example, which is a spot Bitcoin product listed in Amsterdam, have listed Fidelity Digital Assets as the custodian for BTC. So it's not obvious that geographical boundaries are obvious for these players.
