June Bridge Hacks: Three Exploits, One Root Cause

Mon 29th Jun 2026
June saw three separate bridge exploits, each with different technical vulnerabilities but sharing a common underlying issue. **Key Points:** - Three distinct bridge hacks occurred in June - Each exploit used different attack vectors - All three share a fundamental root cause - Cross-chain bridges remain a primary target for exploits Bridge vulnerabilities continue to represent a significant security challenge in web3, with historical data showing they account for nearly 40% of all hacked value in the space.

CoW Protocol Launches Atomic Bundles for Multi-Step DeFi Workflows

Thu 30th Apr 2026
CoW Protocol has introduced **Atomic Bundles**, a reusable smart contract template enabling developers to execute complex, multi-step DeFi operations atomically in a single settlement. **Key capabilities include:** - Loop-borrow-redeposit strategies - Repay debt with collateral - Flashloan-enabled executions - Atomic open/close flows for perpetuals - Multi-step payment and treasury operations All executions maintain CoW Protocol's core features: solver competition, MEV protection, and surplus generation. **For builders**, Atomic Bundles simplify development across lending (one-click looping, collateral swaps), perpetuals (atomic open/close flows), and payments (multi-step flows with zero mid-execution risk). Previously, developers needed to write custom wrapper contracts from scratch for each use case. Now they can fork the template, add their logic, and plug into CoW Protocol's solver network.

The integration uses intent-based transactions - users specify what they want, and solvers find the optimal execution path. **Benefits include:** - Solver-routed execution for better prices - Shared liquidity across $10B+ monthly volume - Simplified user experience with fewer approvals Try CoW Swap on Linea: [swap.cow.fi](https://swap.cow.fi/#/59144/swap/WETH/0x176211869cA2b568f2A7D4EE941E073a821EE1ff) Learn more about the Aave integration: [aave.com/blog/aave-cow-swap](https://aave.com/blog/aave-cow-swap)

Study Shows CoW Swap Leads Intent-Based DEXes in Decentralization and Volume

Thu 27th Mar 2025
A comprehensive 6-month trading analysis reveals CoW Swap's dominance among solver-based DEXes: - **Higher Trading Volume**: ~$200M daily vs $60M (1inch Fusion) and $30M (UniswapX) - **More Decentralized**: Top solver only controls 25% market share, with next five at ~10% each - **Better for Large Trades**: Shows best execution improvement for trades over 100 ETH The study compared CoW Swap, 1inch Fusion, and UniswapX, finding solver-based DEXes generally outperform traditional alternatives through optimized routing and off-chain liquidity access.

Curve Finance Implements CoW Protocol for Fee Collection

Thu 27th Jun 2024
Curve Finance has integrated CoW Protocol's Programmatic Order Framework into its fee collection mechanism. This new system allows Curve to automatically collect fees from AMM pools and efficiently swap them into a unified token without manual intervention. The process involves four components: a fee collector, CoW Swap burner, hooker, and fee distributor smart contracts. Initial results show that orders processed through this system have achieved, on average, 75% more CRVUSD tokens than requested, demonstrating superior performance compared to hard-coded execution paths. This implementation enables Curve to submit orders without predetermining prices, ensuring fair market rates and reducing maintenance requirements.
