**DEXs are now competing in auction-style bidding wars** for your trade orderflow, fundamentally changing how decentralized exchanges operate. **The New DEX Auction Model** To win trades, DEXs must: - Know market rates they can bid - Monitor competitor quotes - Bid strategically without overpaying - **Keep bids private** **Strategic Adaptations** - DEXs colocate with solvers to dynamically outbid competitors - Increased programmability through v4 hooks and concentrated liquidity - LPs help fine-tune pools for maximum volume and profit **Price Freshness Tactics** DEXs align with fast traders through: - **Angstrom**: Auctions trading rights at block tops - **Uniswap Protocol Fee Discount**: Fee-free trading auctions Both incentivize traders to update pool prices to latest market rates. **Competitive Secrecy** DEXs now: - Keep code private - Share quotes only with select aggregators and builders - Make competition harder for rivals This represents just the beginning of evolving DEX competition strategies.

**Wraxyn breaks silence** on using Tycho as their competitive advantage for solver operations. Most Tycho users keep their usage private, but Wraxyn decided to share how they leverage the platform to: - **Win more volume** on UniswapX - **Optimize performance** on CoWSwap - **Gain solver advantages** through Tycho's edge **Why Tycho matters:** Tycho standardizes data from multiple DEXs like Curve and Balancer, following ERC 7815 standards. This eliminates the need for solvers to adapt routing logic to different DEX interfaces. **Key benefits:** - Seamless data streaming - Unified DEX interface - Simplified solver operations Wraxyn's transparency offers rare insight into how professional solvers gain competitive advantages in the MEV landscape.

**Tycho now supports Eulerswap routing** without weeks of integration work. Solvers can access the Uniswap v4 hook by simply adding 'uniswap_v4_hooks' with euler_hook_filter to their client config. **Key advantages:** - **50x effective depth** on stable pairs through just-in-time borrowing from Euler Finance vaults - **Reduced slippage** for large swaps on stablecoin pairs - **Automatic dependency management** via Tycho's Dynamic Contract Indexing (DCI) Eulerswap borrows output tokens from lending vaults during swaps, creating deeper liquidity for pegged assets. This makes it particularly competitive for stablecoin trading. Tycho's DCI handles complex contract dependencies automatically, eliminating manual integration work. The system traces vaults, oracles, and hooks server-side, streaming data to clients for in-memory swap simulation. This marks the first of many hooks Tycho will support, with plans to include Balancer v3, Fluid, and other Uniswap v4 hooks.

**Turbine** is positioning itself as the first trustless peer-to-peer exchange platform. The platform aims to enable direct peer-to-peer trading without requiring intermediaries or centralized control. This approach could address common issues in traditional exchanges like: - Counterparty risk - Custody concerns - Centralized points of failure By operating in a trustless manner, users would maintain control of their assets throughout the trading process. The peer-to-peer model suggests direct matching between traders rather than relying on market makers or liquidity pools. This development follows growing interest in decentralized trading infrastructure that prioritizes user sovereignty and reduces reliance on centralized entities.

**Triangle**, a Rust-based arbitrage bot template, eliminates weeks of infrastructure setup for atomic arbitrage trading. Built by @0xytocinX on Tycho, this **fully open-source** solution provides: - Real-time DEX state monitoring - Battle-tested simulation engine - Audited router contract - Modular pathfinding algorithms The bot automatically builds liquidity graphs, identifies profitable opportunities, and submits trading bundles. **Key features:** - Configurable bribing logic - Adjustable slippage settings - Support for backrunning trades - BuilderNet deployment options Previously, building arbitrage bots required maintaining nodes across chains, debugging DEX logic for months, and implementing complex routing contracts. Triangle streamlines this process into a simple clone-and-configure workflow. **Get started:** ``` git clone https://github.com/nonechuckX/tycho-arbitrage ``` Full specifications: [TAP-4.md](https://github.com/propeller-heads/tycho-x/blob/main/TAP-4.md) Join [tycho.build](http://tycho.build) for bot support and community resources. **Important:** Educational purposes only.

Tycho introduces a solution for low solver volume in Unichain hooks by enabling integration with major DEXs like UniswapX, CowSwap, and 1inch. Key features: - Single integration reaches all Tycho solvers and market makers - ~25ms block processing speed - Automatic routing through new liquidity sources - Open source library for simplified DEX integration DEX builders and lending protocols can now receive flow without individual solver pitching. Integration documentation available at [Tycho docs](https://docs.propellerheads.xyz/tycho). Workshop demonstration available at [YouTube](http://youtube.com/watch?v=TN6MfNFvfx8)

Tycho is offering a $10,000 bounty to developers who can reshape on-chain liquidity into an orderbook format, making decentralized trading more familiar to traditional traders. - Project aims to improve DeFi trading UX by mimicking traditional orderbook interfaces - Integration opportunity with Maverick v2 protocol to enhance liquidity flow - Technical specifications available on [GitHub](https://github.com/propeller-heads/tycho-x/blob/main/TAP-2.md) Interested developers can participate through [tycho.build](http://tycho.build) or direct messages.

PropellerHeads introduces Tycho X, inviting developers to build open-source trading applications using their DEX data infrastructure. Three initial project specifications have been released: - **Pool Explorer**: Tool for exploring on-chain liquidity - **Orderbook**: System to transform blockchain into a centralized limit order book (CLOB) - **Price Quoter**: High-speed token pricing tool with microsecond response times Developers working on these projects will receive comprehensive support in product development, technical implementation, and marketing efforts. This initiative builds on Tycho's foundation as an open-source liquidity indexer that simplifies DEX integration. *Get involved:* https://github.com/propeller-heads/tycho-x
