Bitcoin Custody at a Crossroads: Institutions Build, IPOs Stall

Bitcoin Custody Infrastructure Is Maturing Fast - But Not Evenly

The battle for Bitcoin custody is intensifying on two fronts simultaneously. On one side, a new generation of institutional-grade custody platforms is attracting serious capital and landing blue-chip clients. On the other, even the most established names in self-custody are finding public markets too turbulent to navigate. Together, these developments paint a detailed picture of where Bitcoin financial infrastructure stands in mid-2025 - and where it is heading.

The custody question has always sat at the heart of Bitcoin adoption. Who holds the keys, who bears the risk, and who can be trusted to manage both - these are not abstract concerns. They are the questions that determine whether pension funds, registered investment advisors, and corporate treasuries can participate in Bitcoin at scale. Two recent developments, one from Austin and one from Paris, offer a rare dual lens on how the industry is answering them.

The Facts

Onramp, an Austin-based Bitcoin financial services firm founded in 2023, announced a $12.5 million Series A round led by venture firm Early Riders, valuing the company at $135 million ^[1]. The raise comes as Onramp reports crossing $1 billion in assets under custody with zero security incidents since inception - a record that CEO Michael Tanguma and his team are leaning on heavily in institutional sales conversations ^[1].

The centerpiece of Onramp's offering is its Multi-Institution Custody model, which distributes key control across several regulated custodians rather than concentrating it in a single entity or pushing full responsibility onto the client ^[1]. The architecture relies on partners including BitGo, Coincover, and Tetra Trust, enabling shared control structures that can operate across jurisdictions ^[1]. The model is explicitly designed to resolve a persistent tradeoff in digital asset custody: centralized platforms carry counterparty risk, while self-custody demands significant technical competence and operational discipline. Onramp frames its approach as a middle path that eliminates single points of failure while keeping assets verifiable on-chain ^[1].

The institutional market is responding. UK pension fund Cartwright selected Onramp as custodian for its Bitcoin allocation, and the Bitcoin Policy Institute has formally endorsed multi-party custody frameworks as a model for potential state-level Bitcoin reserves ^[1]. Beyond custody, Onramp launched its broader Onramp Finance platform in April, offering brokerage services across all 50 US states, cash accounts, a payments card, Bitcoin IRAs, and gold access within a single interface ^[1]. Former Blackstone partner David Thayer has joined as a strategic advisor, signaling deliberate outreach to traditional finance infrastructure investors ^[1]. The new capital will be split between product engineering and commercial expansion, including white-label offerings for financial institutions ^[1].

Meanwhile, in Europe, hardware wallet manufacturer Ledger has quietly shelved plans for a public listing ^[2]. The French company, currently valued at more than $4 billion, had engaged major US investment banks including Goldman Sachs, Jefferies, and Barclays to advise on a potential IPO, but no S-1 registration statement has been filed with the SEC - the formal step that would signal a live offering process ^[2]. The company cited difficult market conditions and persistent uncertainty in the United States as reasons for the delay ^[2]. The postponement leaves early investors and employees without a near-term liquidity event, with secondary markets remaining the only available exit route for now ^[2].

Analysis & Context

The contrast between Onramp's momentum and Ledger's hesitation is instructive, but it is not a contradiction. These are two different businesses at two different stages, responding to two different pressures. Onramp is a private company in growth mode, raising capital to capture a market that is forming in real time around institutional Bitcoin adoption. Ledger is a mature, profitable hardware business attempting to navigate public equity markets that remain skittish about crypto-adjacent listings - regardless of underlying business quality. The IPO delay says less about Ledger's fundamentals and more about the broader market's appetite for crypto sector public offerings, which has remained subdued despite Bitcoin's price recovery over recent months ^[2].

What is more significant is the structural argument Onramp is making about custody design. The Multi-Institution Custody model is not a novel concept in principle - multi-party computation and distributed key management have been discussed in Bitcoin circles for years. What Onramp is doing is commercializing that architecture at a moment when institutions actually need it. The collapse of FTX and other centralized platforms in 2022 shattered confidence in single-custodian models and drove retail demand toward hardware wallets like Ledger's ^[2]. But institutional investors cannot simply buy a Ledger device and call it a policy. They need auditable processes, regulated counterparties, insurance frameworks, and reporting infrastructure. Onramp is building precisely that layer. The Cartwright pension fund selection is not just a client win - it is a proof-of-concept that regulated fiduciaries can integrate Bitcoin custody into their existing compliance frameworks using this architecture.

Historically, the phases of Bitcoin adoption have followed a custody infrastructure curve. Retail adoption expanded when consumer exchanges made buying accessible. Institutional adoption accelerated when custodians like Fidelity Digital Assets and Coinbase Custody provided regulated storage. The next phase - deep integration into wealth management, retirement accounts, and bank balance sheets - requires something more sophisticated still. The race to define that standard is underway, and Onramp is explicitly positioning itself to set it. Early Riders partner Liam Nelson stated that the firm backed Onramp specifically to establish MIC as an industry standard ^[1]. That is a deliberate infrastructure play, not just a product bet.
