The world of digital assets is evolving rapidly, and at the heart of this transformation lies a critical infrastructure: crypto custody. As institutional investors eye blockchain-based assets, secure and compliant storage solutions have become the linchpin for mainstream adoption. With traditional financial giants stepping in and agile startups innovating at speed, the race to build the "banks of the blockchain" is well underway.
Why Crypto Custody Matters
“95% of the barriers to institutional acceptance of blockchain assets are related to custody,” said Brendan Blumer, CEO of Block.one, highlighting a fundamental truth in the crypto ecosystem. Without trusted custodians, even the most promising digital assets struggle to gain legitimacy in the eyes of Wall Street.
Just as physical banks safeguard cash and gold, crypto custodians protect private keys—the digital fingerprints that control access to blockchain assets. Loss of these keys can mean irreversible loss of funds. According to Chainalysis, nearly 4 million bitcoins are already lost forever. Meanwhile, cyberattacks continue to plague the industry; CipherTrace reported $5 billion in crypto thefts in 2019 alone.

Crypto custody addresses two primary risks:
- Technical risk: Private key mismanagement or hacking.
- Moral hazard: Misuse or misappropriation of client funds by asset managers.
By acting as a neutral third party, custodians provide both security and transparency—essential ingredients for trust in a decentralized world.
How Custody Works: Cold Storage, Multi-Signature & More
At its core, crypto custody revolves around one thing: securing private keys. These cryptographic secrets grant ownership over digital assets on the blockchain. If compromised or lost, so too are the funds.
Most custodians use a combination of cold storage (offline wallets) and hot wallets (online for liquidity). Cold storage—often using Hardware Security Modules (HSMs)—is isolated from networks to prevent remote attacks. Physical safeguards like biometric vaults add another layer.
But technology alone isn’t enough. The tragic case of QuadrigaCX illustrates this perfectly: when CEO Gerald Cotten died unexpectedly in 2019, approximately $190 million in customer funds became inaccessible because he was the sole holder of the private keys.
This disaster underscores the importance of multi-signature (multi-sig) systems. With multi-sig, multiple parties must approve transactions, ensuring no single point of failure. For example, Cobo Custody uses a model where both the client and custodian hold separate keys—no individual can act unilaterally.
Beyond storage, modern custody platforms offer features like:
- Emergency freeze mechanisms
- White-listed address controls
- Automated reconciliation and reporting
- Real-time auditing tools
These functionalities not only enhance security but also meet the operational needs of institutional clients such as exchanges, hedge funds, and mining operations.
The Global Custody Landscape
Western Institutions Lead with Compliance
2018 marked a turning point as traditional financial titans began entering the space:
- Fidelity launched Fidelity Digital Assets to serve hedge funds and trading firms.
- Goldman Sachs explored offering custody services and invested in BitGo.
- JPMorgan, BNY Mellon, and Northern Trust started developing crypto custody solutions.
- Nomura Holdings partnered with Ledger and Global Advisors to form Komainu, a dedicated custody venture.
Meanwhile, crypto-native players scaled fast:
- Coinbase acquired Xapo’s custody business for $55 million.
- Anchorage raised $17 million to expand its regulated platform.
- BitGo, Coinbase Custody, and Kingdom Trust emerged as leaders, each holding over $1 billion in assets under custody.
Despite progress, regulatory hurdles remain. Bakkt’s delayed launch highlighted the challenges of gaining full regulatory approval in the U.S., underscoring that compliance is still a work in progress.
China’s Grassroots Innovation
In contrast to the structured Western approach, China’s custody ecosystem grew more organically. Early players like Cobo, Matrixport, and Jadepool emerged from within the blockchain industry itself.
Matrixport, co-founded by Wu Jihan (Bitmain’s co-founder), launched Cactus Custody with over $1 billion in managed assets—leveraging existing relationships across Bitmain’s ecosystem.
Similarly, Jadepool evolved from providing staking infrastructure for partners like Hashquark and Hashkey to offering full private-deployment custody solutions.
Startups like inVault, which holds a Hong Kong trust license, emphasize regulatory readiness—an edge in an otherwise gray-market environment.

Beyond Storage: Toward a "Blockchain Bank"
Pure custody is no longer enough. As one industry executive put it: “We’re operating like we’re selling cocaine, but we’re only making cabbage money.” With margins shrinking, providers are expanding into value-added services.
This shift mirrors the evolution of traditional banking—from safekeeping to comprehensive financial services.
Modern crypto custodians now offer:
- Staking-as-a-Service (StaaS): Earn yield by validating transactions on PoS blockchains.
- Lending & borrowing: Unlock capital without selling assets.
- On-chain trading execution: Facilitate internal trades between managed portfolios.
- Fiat gateways: Enable seamless on/off ramps.
- Wallet-as-a-Service (WaaS): Provide wallet infrastructure for exchanges and apps.
For instance, Cobo generates significant revenue through StaaS, passing 80–90% of staking rewards to clients while taking a small commission. Jadepool earns from staking fees, transaction commissions, and lending spreads.
This move toward integrated financial services positions crypto custodians not just as vaults—but as full-fledged blockchain banks.
Challenges Ahead: Regulation & Insurance
Despite growth, two major hurdles persist: regulation and insurance.
No country has established a dedicated regulatory framework specifically for crypto custodians. While some firms claim compliance via state-level licenses (e.g., BitGo Trust in South Dakota), true global standards are absent.
In Hong Kong, guidelines exist for virtual asset fund managers and exchanges—but not standalone custodians. Legal uncertainty remains a systemic risk.
Insurance is equally underdeveloped. Few insurers understand crypto-specific risks, and premiums are high. Even when coverage exists—like Coinbase or Xapo’s policies—its scope is often unclear. In 2023, BitGo faced backlash for allegedly overstating its $100 million insurance coverage.
Moreover, underwriting focuses less on tech and more on team reputation and business history—making it harder for newer entrants to qualify.

Frequently Asked Questions
Q: What is crypto custody?
A: Crypto custody refers to secure storage and management of digital assets, primarily through safeguarding private keys using advanced encryption, multi-signature systems, and cold storage solutions.
Q: Why do institutions need crypto custodians?
A: Institutions require auditable, compliant, and insured solutions to mitigate theft, loss, and fraud risks—conditions necessary for fiduciary responsibility and regulatory compliance.
Q: Can individuals use crypto custody services?
A: Most custodians serve institutional clients (exchanges, funds, enterprises), though some offer enterprise-grade solutions accessible to high-net-worth individuals.
Q: Is crypto custody regulated?
A: Regulation varies by jurisdiction. Some U.S. firms operate under state trust charters, while others rely on general financial licenses. No universal standard yet exists globally.
Q: How do staking rewards work within custody platforms?
A: Custodians allow users to stake their held assets securely, earning inflation rewards. They handle node operation and security while sharing most returns with clients—similar to interest-bearing accounts.
Q: Are all custodial solutions equally secure?
A: No. Security depends on technical architecture (e.g., HSM usage), operational practices (e.g., key distribution), insurance coverage, and regulatory adherence. Due diligence is essential.
Final Thoughts
Crypto custody is no longer just about storing coins—it’s about building trust in a trustless system. As the bridge between traditional finance and decentralized economies grows stronger, custodians play an increasingly central role.
From securing billions in digital wealth to enabling yield generation and compliant access, these platforms are laying the foundation for a new financial paradigm—one where security, innovation, and accessibility converge.
The journey isn’t over. Regulatory clarity, broader insurance adoption, and deeper integration with DeFi will shape the next phase. But one thing is clear: the future of finance is being built on blockchain—and it needs reliable banks to thrive.
