A $3.9 billion transfer moving 43,033 BTC was recorded on-chain and flagged by Whale Alert, with the receiving cluster matching labels used by intelligence dashboards for Twenty One, known as XXI.
The timing aligns with the company’s stated plan to relocate more than 43,500 Bitcoin from escrow into its own custody before it begins trading on the New York Stock Exchange under the ticker XXI.
According to Whale Alert, the transaction carried 43,033 BTC, with monitoring pages showing a spot reference price near $91,374 at the moment of inclusion and a minimal network fee.
Screenshots shared across X display the receiver as 3MEa4sPyGLCf2xQR5k68gUsxYSosJ6UhJh, an address that on-chain sleuthing tools associate with Twenty One’s custody arrangements. Minutes after the alert, Tether CEO Paolo Ardoino posted “XXI, so it begins,” reinforcing the linkage in public commentary.
According to Jack Mallers on X, Twenty One expects to start trading on December 9 and, as part of its closing process, will move “over 43,500 Bitcoin out of escrow and into our custody,” with a proof-of-reserves update to follow.
That statement provides a direct operational explanation for a large consolidation event ahead of the listing date, and it narrows the interpretation away from a fresh market order executed by Tether on the day of the alert.
Corporate materials describing the financing structure indicate a formal relationship between Twenty One and Tether. According to deal documentation, Tether and related parties are the majority owners of Twenty One, with SoftBank described as a meaningful minority investor.
The terms outline that Tether agreed to pre-purchase bitcoin in an amount equal to the private investment in public equity and related notes, then sell those coins to Twenty One at cost at closing. That structure creates an escrow-like path where coins sit with Tether-controlled or affiliated wallets until the de-SPAC completes, at which point they are transferred into Twenty One’s custody.
How the 43,033 BTC Transfer Fits the Deal’s Settlement Timeline
When interpreted through that lens, the 43,033 BTC movement appears to be settlement and custody alignment tied to closing milestones rather than new net demand from Tether today.
The economic purchase of much of this Bitcoin would have been executed earlier under the pre-purchase obligation, then warehoused until transfer. The on-chain footprint therefore reflects an accounting and control change that prepares the balance sheet for public market disclosure and audits, not an abrupt swing in Tether’s treasury strategy.
Mallers’ transparency note about updating proof of reserves also sets a short timeline for external verification. Once Twenty One publishes addresses and inventory details, the receiving side of the transaction can be matched to the company’s disclosures.
Market participants tracking corporate Bitcoin treasuries will then be able to attribute this large cluster with greater certainty and monitor spending, staking to multi-sig, or migration to cold storage patterns that often follow public listings. In previous cycles, similar moves by listed entities have resulted in distinct coin age profiles and low spending behavior, which can be observed over time through standard chain analytics without drawing conclusions about price.
A key nuance in the public conversation has been whether Tether “bought” 43,033 Bitcoin on the day of the alert. The distinction matters for interpreting flows.
Under the stated financing structure, Tether’s role was to source Bitcoin equal to the PIPE and notes and to sell those coins to Twenty One at close. The alert corresponds to that inventory shifting from an escrow or Tether-affiliated holding point into addresses used by Twenty One, which is consistent with a back-office milestone tied to the listing calendar.
Ardoino’s post and Mallers’ prior statement together provide the necessary corroboration for that interpretation without relying on third-party commentary.
What the chain data suggests: inventory transfer, not a spot-market buy
For readers tracking the mechanics, on-chain review typically focuses on input composition, change outputs, and clustering across recent transactions associated with the labeled wallets.
The address 3MEa4sPyGLCf2xQR5k68gUsxYSosJ6UhJh can be cross-referenced against prior inflows from sources tagged as Twenty One Capital or Tether PIPE wallets in intelligence platforms, then traced forward as coins are redistributed to cold storage.
Those movements, if they occur, would appear as a series of peel transactions or batched consolidations as custodians finalize vault layouts for long-term safekeeping ahead of earnings cycles.
The corporate relationship remains central. Majority ownership by Tether and Bitfinex, together with SoftBank’s reported minority stake, binds Twenty One’s treasury policy to entities that already maintain large Bitcoin balances and infrastructure.
The pre-purchase clause, paired with the resale at cost, reduces execution risk around closing because it fixes the sourcing mechanics before the de-SPAC completes. It also explains why the most significant observable footprint is a transfer rather than a series of market orders at the point of listing.
For market structure observers, that distinction separates liquidity events from control changes, helping avoid misclassifying a custody move as a buy impulse.
The listing date provides a clear next checkpoint. According to Mallers, the company plans to begin trading on the NYSE on December 9 under ticker XXI, after which updated proof of reserves will allow public reconciliation of the holdings figure, currently referenced as more than 43,500 BTC.
At that point, filings and investor communications can be compared with chain data to confirm the end state of the transfer sequence.
Thus, Whale Alert flagged the on-chain transfer as using standard fee economics typical of a high-value consolidation, reinforcing the view that this was a planned settlement rather than a time-sensitive execution.
Mallers has framed the move from escrow into Twenty One’s custody as part of closing logistics, and Ardoino’s post publicly linked the activity to XXI.
According to transaction monitoring across intelligence platforms, the receiving address matches clusters used by Twenty One, and further redistribution to cold wallets would be a typical next step before the company publishes a proof-of-reserves file.
The transfer, therefore, reads as a realignment of custody and control tied to the de-SPAC close and listing calendar for Twenty One.
