Curv: The MPC Custody Platform Coinbase Bought
Curv built one of the first institutional MPC custody platforms — key-shares instead of hardware security modules. Founded 2018 by Itay Malinger and Dan Yadlin. Acquired by Coinbase March 2021, weeks before the Nasdaq direct listing, and folded into Coinbase Custody.
Curv built one of the first institutional custody platforms to replace the private key with distributed key-shares. Founded in Tel Aviv in 2018 by Itay Malinger and Dan Yadlin, it was acquired by Coinbase in March 2021 — weeks before Coinbase's Nasdaq direct listing — and folded into Coinbase Custody. It remains one of the earliest large Israeli exits in institutional digital-asset infrastructure.
Curv was an Israeli digital-asset infrastructure company that built an institutional cryptocurrency custody platform on multi-party computation (MPC). It was acquired by Coinbase in March 2021 and integrated into Coinbase Custody. The transaction is one of the reference deals in the Israeli institutional crypto-infrastructure category, alongside Galaxy Digital's acquisition of GK8 in 2022.

The architectural argument Curv was built on
Institutional crypto custody in 2018 ran on hardware security modules. The private key existed as a single object, protected by physical and procedural controls: air-gapped machines, vaults, multi-person ceremonies, geographic separation of backup shards. The architecture was inherited from traditional key management, and it carried one inherited flaw. The key existed. Something could therefore take it.
Every large historical custody loss traced back to that fact — a key extracted, a signing machine compromised, a backup seed reconstructed by someone who should not have been able to reconstruct it. The controls were procedural because the cryptography was not doing the work.
Curv's proposition was to move the problem into the cryptography. Under MPC, the private key is never assembled — not at generation, not at signing, not in backup. Independent parties each hold a mathematical share. A transaction is signed collaboratively, each party contributing a partial computation, and the completed signature emerges without the underlying key ever existing as a whole in any location. There is no key to steal because there is no key.
The practical consequence mattered more to institutions than the theoretical one. MPC custody moves policy enforcement from paperwork into math: transaction limits, approval quorums, whitelists, and role separation become conditions of the signing protocol rather than rules a compliance team hopes people follow. For a bank, that is the difference between a control and an intention.
Curv's founders and the Israeli cryptography base
Curv was founded in 2018 by Itay Malinger as chief executive and Dan Yadlin as chief technology officer, both from Israeli national-security technical backgrounds — the same recruiting pool documented across the Unit 8200 alumni cohort that seeded most of the Israeli security-infrastructure category.
This is the specific reason Israel produced disproportionate output in MPC custody. Threshold cryptography is not a product problem that a good engineering team can reach by iteration. It is applied academic cryptography, and it requires people who can implement threshold ECDSA correctly and defend the implementation against adversaries who will attack the protocol rather than the perimeter. Israel has that population concentrated in a small number of places, and the commercial digital-asset category recruited directly from them.
The Coinbase acquisition and its timing
Coinbase announced the Curv acquisition in March 2021. The price was not disclosed. The timing was the informative part: the transaction landed weeks before Coinbase's direct listing on Nasdaq the following month, at the point of maximum scrutiny on the completeness of its institutional product line.
Coinbase Custody was already among the largest qualified custodians in the market, and it was built on cold storage. What it lacked was an MPC capability — the warm, policy-programmable signing layer that institutional trading desks need when assets have to move on trading timescales rather than vault timescales. Buying Curv closed that gap with a working product and the cryptography team behind it, rather than a multi-year internal build.
The acquisition also established a Coinbase engineering presence in Tel Aviv, following the pattern of US platforms acquiring Israeli infrastructure teams and keeping them in place.
Where Curv sits in the Israeli digital-asset cohort
Curv belongs to a small, unusually consequential group of Israeli companies that built the plumbing of institutional digital assets rather than consumer-facing crypto products.
Fireblocks, founded the same year, was Curv's direct category competitor on MPC custody and took the opposite path — staying independent, raising through the cycle, and becoming the largest company in the category. GK8 built air-gapped cold custody and was acquired by Galaxy Digital for roughly $44 million in November 2022, in the immediate post-FTX repricing. Bancor built the protocol layer that seeded automated market making. StarkWare built zero-knowledge scaling infrastructure.
Read together, the cohort makes a structural point about the Israeli position in digital assets: the value was captured in cryptography and custody, not in exchanges or tokens. The exits went to US platforms — Coinbase, Galaxy — because the buyers of security infrastructure are the venues that hold the assets. It is the same acquisition logic that runs through the Israeli cybersecurity category, applied to a younger market.
FAQ
What was Curv?
An Israeli digital-asset infrastructure company founded in Tel Aviv in 2018 that built an institutional cryptocurrency custody and wallet platform using multi-party computation. It sold to banks, exchanges, asset managers, and corporate treasuries, and was acquired by Coinbase in March 2021.
Who founded Curv?
Itay Malinger, who served as chief executive, and Dan Yadlin, chief technology officer. Both came from Israeli national-security technical backgrounds.
What is MPC custody and why did it matter?
Multi-party computation custody distributes a private key as mathematical shares held by independent parties. The key is never assembled — not at generation, signing, or backup. Transactions are signed collaboratively. Because no complete key exists, there is no key to extract, which removes the single point of failure at the root of the largest historical custody losses. It also lets institutions enforce transaction policy inside the signing protocol rather than through procedure.
How much did Coinbase pay for Curv?
Coinbase did not disclose the price. The acquisition was announced in March 2021 and closed shortly before Coinbase's April 2021 direct listing on Nasdaq.
Why did Coinbase want Curv?
Coinbase Custody was built on cold storage and lacked an MPC layer — the warm, policy-programmable signing capability institutional trading desks require. Acquiring Curv delivered a working product and its cryptography team ahead of the direct listing, instead of a multi-year internal build.
What happened to Curv after the acquisition?
The platform was integrated into Coinbase Custody and the team was absorbed into Coinbase, establishing a Coinbase engineering presence in Tel Aviv.
Who were Curv's competitors?
Fireblocks was the direct MPC competitor and remains independent. GK8 competed from the air-gapped cold-custody side and was acquired by Galaxy Digital in November 2022. Together with StarkWare, these companies define the Israeli institutional digital-asset infrastructure cohort.
