The numbers from February are worth examining carefully — not to declare victory, but to understand precisely what improved, and what didn’t.
According to PeckShield, the crypto ecosystem recorded $26.5 million in total losses across 15 hacking incidents in February 2026. That is the lowest monthly figure since March 2025. Month-over-month, it represents a 69.2% decline from January’s $86.01 million. Year-over-year, the contrast is extreme: February 2025 saw $1.5 billion in losses, inflated primarily by the $1.4 billion Bybit drain.
Remove that single outlier and the structural comparison is less dramatic — but the directional signal is still real. The industry is getting harder to exploit at scale.
What the Data Shows
Five incidents accounted for over 98% of February’s total losses. The largest was YieldBlox.finance at approximately $10 million, followed by a bridge exploit on the IoTeX network at $8.8 million. Cross Curve lost around $3 million, FOOM CASH $2.26 million, and Moonwell approximately $1.8 million.
The pattern is consistent with what security researchers have observed across prior months: in the absence of a single catastrophic event, total losses compress significantly. The industry’s loss statistics are not normally distributed — they are dominated by outlier incidents. February had none.
That is meaningful, but it is not the same as saying the attack surface has shrunk.
What Actually Drove the Improvement
Security commentary tends to attribute declining hack figures to improved audit practices, AI-assisted threat detection, and more rigorous smart contract reviews. These are real factors. Audit coverage across DeFi has expanded materially over the past 18 months, and continuous monitoring tooling has improved.
But February’s data reflects something more structural: the five largest exploits all targeted protocols with mutable, upgradeable, or bridged architectures. Bridge contracts, by design, require trusted relay mechanisms and upgradeable logic to coordinate cross-chain state. That architecture is a persistent attack surface regardless of audit quality.
This is the distinction that matters. An audit assesses code as it exists at review time. It cannot account for what happens to upgrade keys after deployment, how governance votes on implementation changes will be managed, or whether a bridge operator’s infrastructure will be compromised months later. The Bybit breach that defined February 2025 was not a smart contract exploit — it was a failure of key management infrastructure around an upgradeable system.
The Residual Risk Profile
The February data is encouraging. The residual risk profile has not fundamentally changed.
Billions of dollars remain locked in contracts governed by admin keys, proxy patterns, and upgrade mechanisms. Each of those represents an ongoing trust assumption: that the key holder will not be compromised, will not act adversarially, and will execute governance processes correctly under operational pressure.
That assumption has been violated at scale, repeatedly, across protocols with strong reputations and substantial audit histories. The attack is not always against the contract itself — it is against the human and operational infrastructure surrounding the contract’s mutable components.
This is the class of vulnerability that OWASP formally catalogued as SC10 in its Smart Contract Top 10: 2026. Proxy and upgradeability vulnerabilities are now recognized as a top-tier systemic risk, not an edge case.
The Architectural Answer
The only way to permanently remove SC10-class risk from a protocol is to eliminate the upgrade surface at deployment.
0xKeep’s V11 contract contains no proxy pattern, no admin key, no implementation pointer, and no function capable of altering contract state after deployment. There is no upgrade mechanism to compromise because there is no upgrade mechanism. The February figures reinforce why this matters: in a month where bridge and upgradeable contract exploits still accounted for the majority of losses, protocols with static, immutable architectures were not part of the incident log.
This is not a comparative marketing claim. It is a description of what “Write Once, Run Forever” means in practice, measured against real attack data.
What to Watch
The trend is positive. February’s $26.5 million is a meaningful data point in a multi-month pattern of declining large-scale exploits. Continued improvement will depend less on audit coverage — which is already high among established protocols — and more on structural decisions made at the architecture level: whether protocols choose to retain upgrade mechanisms, what governance controls surround those mechanisms, and whether the operational security around admin keys keeps pace with the adversarial environment.
The best month for security in nearly a year is not the moment to relax architectural standards. It is the moment to examine which design decisions produced the outcome, and to apply them consistently going forward.
0xKeep operates on an immutable, zero-admin-key architecture. No wallet — including those controlled by the 0xKeep team — can pause, modify, or interact with deployed contracts. Time is the only admin.
