CoW Protocol Launches Fair Combinatorial Batch Auctions (FCBA)

CoW Swap has introduced cross-chain swaps to Bitcoin, maintaining its signature MEV (Maximal Extractable Value) protection. **Key Features:** - Direct Bitcoin swaps across different blockchains - Built-in MEV protection to prevent front-running - Seamless bridge and swap experience **What This Means:** Users can now swap tokens to Bitcoin across chains without exposure to MEV attacks, which typically occur when traders' transactions are exploited by bots. The platform combines cross-chain functionality with the same protections previously available for single-chain swaps. Learn more at [swap.cow.fi](http://swap.cow.fi)

CoW Protocol has released its Token Transparency disclosure report in partnership with Blockworks, marking a shift toward verifiable documentation over traditional press releases. The filing provides detailed information about: - COW token utility and functionality - Governance structure and mechanisms - Token distribution and economics This transparency initiative represents a new standard in the industry, allowing users to independently verify token information rather than relying solely on promotional materials.

Safe{Mobile} users can now connect their multisig wallets to [CoW Swap](https://cow.fi) using WalletConnect, bringing MEV-protected trading to mobile devices. **Key features:** - Access CoW Swap's price aggregation across exchanges like Uniswap and 1inch - Full MEV protection for multisig transactions - Manage DAO and team treasuries on the go This integration extends CoW Swap's existing multisig support, which launched earlier this year with swap and bridge functionality. Teams can now execute protected trades from anywhere, without being tied to a desktop setup. The mobile integration maintains the same security standards as desktop multisig operations while adding flexibility for treasury management.

**CoW Protocol's batch auction system now powers Lido Finance's Fast Swaps**, removing the vulnerability window that bots exploit for front-running. **How it works:** - Batch auctions group transactions together - Eliminates the time gap bots use to front-run individual trades - Provides instant liquidity for unstaking across ETH, WETH, USDC, USDT, USDS, and WBTC - No withdrawal queue required The integration builds MEV protection directly into Lido's interface, allowing users to unstake without waiting while maintaining competitive pricing.

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.
