- Axios has reported that Visa is in talks to buy the crypto custody firm Fireblocks for around $2.5bn. Neither company has confirmed the talks or the figure.
- Fireblocks sells infrastructure to banks, exchanges and payment firms. It is not a service a member of the public signs up to.
- Mastercard has already completed its purchase of the payments firm BVNK, at a price reported as up to $1.8bn.
Two companies handle the overwhelming majority of card payments in Britain, and both are now buying the machinery that stores and moves digital money. Mastercard’s purchase is done. Visa’s is a report of talks, which is a considerably smaller thing than a deal.
The companies being bought are the ones banks lean on to hold and move crypto safely. If the two largest card networks end up owning that layer, the same pair of firms that already sit between your card and your bank would also sit behind the newer payment rails being built alongside them. You would not see that on a receipt. It would show up in who sets the fees, and who gets access.
What Fireblocks actually does
Fireblocks was founded in 2018 and sells custody and transfer technology to institutions. Its customers are exchanges, banks, brokerages and payment companies, which is why most people who own crypto have never heard of it despite possibly relying on it.
The core problem it solves is key management. Owning crypto means controlling a , a long secret number that proves the coins are yours and lets you move them. For an individual, holding your own keys means a hardware wallet and a written-down . For a bank moving client assets, that approach does not survive an audit.
Fireblocks’ answer is to split the key into fragments stored on separate machines, so no single device ever holds the whole thing, and a transaction only signs when several of them co-operate. Around that sits the duller but equally important part: approval workflows, address whitelists, and a record of who authorised what.
Talks are not a deal, and no price is confirmed
Axios reported the negotiations and The Defiant carried the report onward. We have not been able to read the Axios piece directly, and neither Visa nor Fireblocks has said anything publicly about it, so everything here rests on a single original report with no named party confirming it. Deals at this size collapse, and reported prices during negotiations routinely differ from the one that eventually appears in a filing.
Mastercard got there first
The comparison is the useful part. Mastercard has completed its acquisition of BVNK, a company that builds stablecoin payment infrastructure for businesses, at a price described as up to $1.8bn. That phrasing usually signals a headline number including payments conditional on the business hitting targets, so it is a ceiling rather than a cheque.
Visa has been working the consumer end of the same strategy for a while, including its tie-up with Mesh that lets balances held in a crypto wallet be spent at ordinary checkouts, which we covered in our business coverage. Buying Fireblocks would be the other half: the storage and settlement layer underneath.
Both companies are reaching for the same thing, which is ownership of stablecoin rails rather than a partnership with whoever runs them.
An inference of ours, not something anyone involved has said: part of what Fireblocks sold its clients was neutrality. It was infrastructure that belonged to nobody in particular, which suited banks and exchanges that did not want their custody stack owned by a competitor or a payments network they also negotiate fees with. If the deal closes, that pitch changes, and rivals such as Copper, BitGo and Anchorage become more interesting to anyone who valued it.
What a UK reader would and would not notice
In the short term, nothing. Fireblocks sits behind the firms you use rather than in front of them, and a change of owner does not alter how an exchange handles your account or what protections you have if it fails.
The longer-term version is about cost and speed in places where crypto is already doing a job quietly, mainly business payments and cross-border transfers. If a card network owns both the settlement infrastructure and the merchant relationships, stablecoin payments get easier for banks to offer. Whether that reaches retail customers in Britain depends less on Visa than on the FCA, which is still finalising its rules for stablecoins and the firms that issue and safeguard them.
What to watch
A confirmation or a denial from either company, and whether a price survives contact with an actual announcement. Until one of those arrives, this is one outlet’s reporting on private negotiations.
After that, watch Fireblocks’ existing clients. If institutions that chose it partly because it was independent start publicly adding a second custody provider, that tells you more about how the industry reads this deal than any statement from the buyer will.
