From Smart Contracts to Private Keys: Why Institutional Custody Requires Distributed MPC
By Jacelynn Pang, Global Channels Director & Group Marketing Director, ChainUp Key Takeaways Attackers are no longer focused on finding zero-day bugs in smart contracts. Today, 43.8% of all stolen digital asset value traces directly to compromised private keys, administrative API credentials, and operator signing workflows. Despite year-over-year drops in total attack frequency, individual breach […]
MPC Is Necessary, Not Sufficient: The Institutional Custody Gaps It Doesn’t Cover
Key Takeaways Multi-Party Computation (MPC) eliminates the single private key as a single point of failure. It is the established baseline for institutional digital asset operations, but it addresses only the cryptographic signing layer. Cryptography does not govern intent. Major custody breaches frequently occur above the key-management layer—specifically within approval workflows, role-based access controls, transaction […]
Coldcard Exploit 2026: Lessons for Institutional Crypto Custody
Key Takeaways The estimated $130M Coldcard exploit proved that offline hardware fails if built on a single cryptographic key. A firmware flaw reduced key entropy down to a brute-forceable 40 bits, allowing remote extraction without breaching the physical device. Security concerns sparked a 2026 record of 890,000 BTC moved in a single week, highlighting the […]
MPC Wallets Aren’t Enough: What Institutional Crypto Custody Actually Requires
Key Takeaways MPC is the baseline now, not the differentiator. Distributing signing authority across independent key shares removes the single point of failure behind most major custody breaches. Any provider still building around one private key is selling a design the market has already moved past. The real value is governance, not cryptography. Thresholds and […]
What Is a Self-Custody Wallet In Cryptocurrency?
Key Takeaways A self-custody wallet (also called non-custodial) means you, and only you, hold the private keys to your crypto, without relying on third-party intermediaries. Self-custody gives you full ownership, better privacy, and direct access to Web3 — but it also places full responsibility on you. Custodial wallets hand key control to a third party […]
How Does Crypto Custody Work? The Complete Guide for Businesses in 2026
Key Takeaways The crypto custody provider market grew to $3.69 billion in 2026 and is projected to reach $7.74 billion by 2032, driven by institutional demand and regulatory enforcement. Crypto theft hit $3.4 billion in 2025, followed by $771.8 million stolen in just the first four and a half months of 2026, proving that institutional-grade […]
Best Hardware Wallet for Altcoins: 2026 Ultimate Guide
Key Takeaways Rising multi-billion dollar crypto thefts and high-profile exchange hacks have turned self-custody into an absolute necessity rather than an optional security hobby. Managing a diverse altcoin portfolio is uniquely complex because assets are scattered across fragmented blockchains (like EVM, Solana, and UTXO) requiring distinct app interfaces, network coverages, and signing workflows. This guide […]
Mt. Gox 10 Years Later: What Really Happened and What We Learned
Key Takeaways: Mt. Gox failed due to a multi-year drain of 850,000 BTC, enabled by weak custody, poor reconciliation, and a lack of internal controls. The exchange’s failure showed that storing large amounts of customer funds in hot wallets without institutional-grade segregation is catastrophic. The collapse birthed modern standards for Proof of Reserves, cold storage, […]
2026 Institutional Custody Architecture: Why MPC Alone Is Not Enough
Key Takeaways Over $3.4 billion was lost to crypto exploits in 2025, primarily due to operational and execution failures rather than broken cryptography. Multi-Party Computation (MPC) remains the gold standard for securing keys at rest, but it requires integrated policy enforcement to protect the full transaction lifecycle. Institutional confidence now relies on a comprehensive security […]
The New Infrastructure of Enterprise Custody: Merging Multi-Sig and MPC in 2026
In early 2025, the digital asset landscape faced a watershed moment when a major exchange’s multi-signature cold storage was exploited, leading to a $1.5 billion loss. This breach—one of the largest in history—highlighted a critical truth: even the most respected security models can fail if they aren’t adapted to modern threats. As we move through […]
