Briefly
- Technique retains its $72 billion Bitcoin stash with a number of custodians, however will not publicly identify them, citing safety issues regardless of stress from crypto group.
- Coinbase confirmed it is considered one of Technique’s custodians, whereas blockchain analytics agency Arkham claims to have traced 70,000 BTC to Constancy.
- SEC filings reveal Technique makes use of solely NYDFS-regulated custodians, narrowing the checklist to 9 doable companies together with BitGo, Gemini, and NYDIG.
Bitcoin treasury big Technique has all the time been coy about naming its BTC custodians. However folks exterior the agency do know who they’re.
For starters, Technique has repeatedly cited its “numerous custody preparations”—there is no such thing as a one unique custodian that’s holding onto its practically $72 billion price of BTC on the corporate’s behalf. A spokesperson for Coinbase confirmed it’s considered one of Technique’s custodians when requested by Decrypt—however burdened that MSTR has beforehand named Coinbase as considered one of its custodians.
Technique didn’t instantly reply to a request for remark from Decrypt on its determination to withhold the names of its custodians.
The problem of Technique’s Bitcoin holdings, and who precisely holds the keys to the $72 billion stockpile, was dropped at the fore not too long ago following controversial statements by the corporate’s founder Michael Saylor. Again in Could, Saylor stated it was a “dangerous concept” to publicly share “proof of reserves” or in any other case present an in depth checklist of custodians, citing safety issues.
Our institutional staff is crushing it – two superior stats from our QBR this week:
1) 8 of the highest 10 publicly traded corporations with BTC on their steadiness sheet use Coinbase Prime.
2) There’s $140B of crypto in US ETFs, and 81% of that’s saved with Coinbase. We’re monitoring > 50…

Skeptical crypto market observers, lots of whom lived by way of the contagion-inducing blowups of FTX, Three Arrows Capital, Celsius, and others, criticized Saylor on the time for refusing to share these particulars—although others supported the cautious method to operational safety. The matter reentered public discourse two weeks in the past when Coinbase CEO Brian Armstrong proudly boasted on X that his firm custodies Bitcoin for eight of the ten publicly traded BTC holders—strongly implying Coinbase is considered one of Technique’s custodian.
Armstrong’s tweet, nevertheless, might not have been as controversial as some initially interpreted. In keeping with Coinbase, Saylor had already beforehand named Coinbase as considered one of its custodians. In any case, Technique—previously MicroStrategy—is a public firm, buying and selling beneath the ticker MSTR, so some quantity of disclosure is anticipated.
Certainly, Technique disclosed particulars about its custodians to the SEC in an April 2023 letter. The regulator wrote to Technique on April 5, 2023, to pointedly ask how “latest bankruptcies within the crypto business and failures of sure monetary establishments, and the downstream results of such occasions, have impacted or might affect your enterprise.”
On the time, the business was reeling from FTX’s $8 billion collapse. Then Silvergate Financial institution and Signature Financial institution have been pressured to wind down their operations in March. The entire interval left regulators and shareholders questioning whether or not Technique’s BTC was nonetheless secure—significantly as a result of Technique had used a few of its BTC as collateral for a mortgage from Silvergate.
However when Technique replied two weeks later, answering the SEC’s request to “please inform us the names of your custodians,” the corporate invoked SEC Rule 83 to maintain the main points confidential.
What was left public is that Technique retains its Bitcoin in accounts at “U.S.-based, institutional-grade custodians which have demonstrated information of regulatory compliance and data safety, and all of our custodians are New York Division of Monetary Providers (“NYDFS”)-regulated custodians.”
That’s descriptive sufficient to whittle down the checklist of possible custodians.
Of the 35 recipients of NYDFS BitLicenses, solely 9 had restricted goal belief charters when Technique despatched its letter in spring of 2023. These embrace BitGo, Coinbase, GMO-Z.com, Constancy, Bakkt, Gemini, NYDIG, Paxos, and Commonplace Custody & Belief Firm.
Coinbase isn’t an enormous shock, particularly as a result of the trade has typically been cited in MSTR filings as its “principal marketplace for Bitcoin.” In truth, Technique did its first-ever Bitcoin purchase by way of Coinbase.
In the meantime, blockchain analytics platform Arkham Intelligence claims to have traced 70,000 price of the corporate’s BTC to Constancy in Could.
The corporate hasn’t confirmed that it holds a few of its BTC with Constancy, however the agency does match the profile for being on the checklist. A supply acquainted with Constancy Digital Asset Providers enterprise informed Decrypt the agency takes its shoppers’ safety very critically and wouldn’t disclose—straight or not directly—its shoppers’ data.
There’s a couple of under-the-radar corporations on the checklist of potentials, too.
GMO-Z.com is the U.S. subsidiary of GMO Web Group, a big Japanese web conglomerate that owns Onamae area registration, webhosting, funds, and a crypto trade and mining enterprise. It’s additionally the issuer of GYEN, which it calls the primary regulated Japanese YEN stablecoin, and ZUSD, a U.S. dollar-pegged stablecoin.
It’s unlikely GMO-Z holds any of Technique’s Bitcoin as a result of the corporate explicitly says it custodies reserves in GYEN or ZUSD, its U.S. dollar-pegged stablecoin.
The Commonplace Custody & Belief Firm, which Ripple acquired in June 2024, was a subsidiary of PolySign. PolySign was co-founded by Ripple co-founder Arthur Britto, Ripple Chief Know-how Officer David Schwartz and is led by CEO Jack McDonald. McDonald can be the SVP of Stablecoin at Ripple.
Commonplace Custody has gone out of its strategy to fly beneath the radar, positioning itself as an institutional grade, white-label custodian.
Bakkt Belief Firm can be on the checklist. Former father or mother firm Bakkt has been many issues through the years. In 2019, Bakkt acquired Digital Asset Custody Firm and landed a restricted goal belief constitution—making it one of many earliest companies to change into an NYDFS-regulated Bitcoin custodian.
However the firm bought its custody enterprise to its father or mother firm. Neither Bakkt nor Intercontinental Change responded to a request from Decrypt about whether or not the custody enterprise nonetheless has shoppers.
