Tycho X Launches Open Source Trading Apps Initiative

Router v3 has completed a comprehensive 3-month audit process, with the full report now available on GitHub. **Key Security Features:** - The contract is **immutable**, preventing unauthorized modifications - New AMM executors must pass through a **3-day timelock** before implementation - This timelock provides a safety window for community review of any proposed changes The audit report can be reviewed at: [GitHub Audit Report](https://github.com/propeller-heads/tycho-indexer/blob/8b8684fb324db8df54473f1f4838966e6a76cede/crates/tycho-execution/docs/audits/Max_2026-05-15.pdf) These security measures build on the protocol's existing governance framework, where contracts, executors, timelocks, and treasury flows remain fully auditable on-chain.

**Router v3 tackles transaction reverts with vault injection** Users can now prevent failed trades by depositing tokens into a vault within Router v3. The system automatically uses just enough funds from your vault to complete trades that would otherwise fail. **Key features:** - Deposit funds and set spending limits - Router draws minimal amounts needed to save trades - Reduces gas fees by eliminating extra transfers - Vault balance can be used directly for market making The vault system streamlines fee handling by moving them directly to your router balance instead of requiring separate transactions.

Fynd has released Router v3, an open-source routing solution that enables protocols to monetize transaction flow and reduce failed trades. **Key Features:** - Take fees and subsidize trades without deploying additional smart contracts - Self-hosted router and fee-taking infrastructure - Anti-revert mechanism that injects tokens from your vault to prevent transaction failures - Customizable deposit limits to control subsidy amounts The router automatically uses minimal funds needed to save trades from reverting, addressing a common pain point in DeFi swaps. All code runs on your own server, giving protocols full control over their routing infrastructure. [Learn more about Router v3](https://fynd.com)

The Uniswap Foundation has awarded a grant to Tycho and Fynd to build faster infrastructure for decentralized exchange operations. **Key improvements:** - Pool simulations accelerated to 900 nanoseconds per quote - Indexing capability for over 100,000 Uniswap pools with zero state inconsistencies - Maintains accuracy during Flashblocks and blockchain reorganizations - Enables trading of v4 hooks within minutes of deployment The Tycho platform is now available for developers to integrate Uniswap v4 pools. Users can run the [quickstart guide](https://docs.propellerheads.xyz/tycho/for-solvers/quickstart) to subscribe to pools and simulate swaps. This infrastructure upgrade aims to improve the speed and reliability of decentralized exchange operations across the Uniswap ecosystem.

A trading bot called Stabiliser completed a 60-day live test on Ethereum mainnet, trading the ETH/USDC pair with notable results: **Performance Metrics:** - **+9.55% profit** in USD terms (after gas costs) - **32% outperformance** vs. simply holding ETH - Executed during a period when ETH declined 22% **Trading Activity:** - ~1,500 trades executed - Selected from 18,000 identified opportunities - Ran on mainnet before public release The bot demonstrated its ability to generate positive returns in a declining market by actively managing positions rather than holding static assets. The strategy's selectivity—executing only 8% of identified opportunities—suggests a disciplined approach to trade execution.
