# Crypto Bridge Hacks Surpass $340 Million in 2026 — 14 Major Exploits Target Cross-Chain Protocols
Cross-chain bridge protocols have become the most targeted infrastructure in cryptocurrency security, with blockchain security firm PeckShield reporting that hackers have drained a cumulative $340.7 million through 14 major exploits so far in 2026. The relentless attack wave has intensified in June, with Gnosis Pay and TesseraDAO both suffering exploits within the first two days of the month.
The staggering figure underscores a persistent vulnerability in the crypto ecosystem’s interoperability infrastructure. Bridges — which allow assets to move between different blockchain networks — have long been considered the weakest link in DeFi security, often containing complex smart contract code that presents a wide attack surface.
## Latest Victims: Gnosis Pay and TesseraDAO
June 2026 opened with back-to-back security incidents that sent shockwaves through the DeFi community.
**Gnosis Pay Exploit:** Gnosis Pay, a self-custody crypto card platform, suffered an exploit that bypassed its “delay module” feature — a safety mechanism designed to impose a three-minute hold on outgoing transactions, giving users time to react to suspicious activity. A bug allowed an attacker to circumvent this protection entirely.
Gnosis co-founder Martin Köppelmann issued an urgent warning on X, advising all users: “Withdraw all funds (EURe and GNO) immediately.” He confirmed that Gnosis would cover all user losses. The team also requested bridge validators to pause activity to prevent cross-chain movement of stolen funds.
**TesseraDAO $2.5 Million Loss:** In a separate incident, the TesseraDAO protocol lost approximately $2.5 million to an exploit. The attack methodology remains under investigation, but initial reports suggest a smart contract vulnerability was exploited.
## The $340.7 Million Reality
PeckShield’s data reveals a troubling acceleration of bridge-focused attacks in 2026:
– **14 major bridge exploits** recorded year-to-date
– **$340.7 million** cumulative losses from bridge protocols alone
– **Average exploit: $24.3 million** per incident
– **Largest attack:** The $294 million KelpDAO exploit remains the biggest crypto hack of 2026
The KelpDAO incident alone accounts for the vast majority of bridge-related losses this year. In that attack, perpetrators drained nearly $300 million from the liquid restaking protocol by compromising cross-chain messaging infrastructure.
## Why Bridges Remain Vulnerable
Security experts point to several factors that make bridges a persistent target:
1. **Smart Contract Complexity** — Bridges require intricate smart contract logic to lock, mint, burn, and unlock assets across chains. Each additional layer of complexity introduces potential vulnerabilities.
2. **Validator/Relayer Security** — Many bridges rely on offchain validators or relayers to confirm cross-chain transactions. Compromising even a subset of these actors can allow fund theft.
3. **Upgradeability Risks** — Bridge contracts are often upgradeable, creating a governance attack surface where malicious proposals can redirect funds.
4. **Liquidity Concentration** — Large liquidity pools make bridges attractive targets. A single successful exploit can yield hundreds of millions.
## The Security Response
The industry has responded with a mix of technical and procedural measures:
– **Formal verification:** More projects are adopting formal verification methods to mathematically prove contract correctness
– **Insurance protocols:** DeFi insurance providers report surging demand for bridge-specific coverage
– **Slow migration to native interoperability:** The industry is gradually moving toward trust-minimized bridging solutions like ZK-based light clients and intent-based architectures that reduce reliance on validator sets
## Outlook
With $340 million already lost and June just beginning, 2026 is on pace to challenge previous years for total losses from crypto bridge hacks. Security firm TRM Labs has labeled cross-chain infrastructure as the single greatest security risk in the crypto ecosystem.
For users, the safest approach remains caution: limit exposure to bridge protocols, verify security audits, and avoid keeping large balances in bridge contracts longer than necessary for a transaction.

### FAQ
**How much has been lost to bridge hacks in 2026?**
PeckShield reports $340.7 million lost across 14 major cross-chain bridge exploits so far in 2026, with the $294 million KelpDAO hack being the largest.
**What happened to Gnosis Pay?**
Gnosis Pay suffered an exploit that bypassed its delay module security feature. The co-founder urged all users to withdraw funds immediately and confirmed user losses would be covered.
**Why are bridges so vulnerable to hacks?**
Bridges involve complex smart contracts, offchain validator sets, upgradeable governance, and concentrated liquidity pools — all of which create multiple attack surfaces for sophisticated hackers.
