PropellerSwap

Fynd has launched on BNB Chain, offering users a customizable routing solution for token swaps. **Key Features:** - Deploy your own router with configurable filters - Option to filter out fee-on-transfer and rebasing tokens - Access to long-tail and newly launched assets - Fee-taking capabilities to monetize flow - Trade subsidization options - Open-source implementation The platform allows traders to configure their routing preferences based on risk tolerance and trading strategy. Users can choose conservative settings by filtering problematic token types, or opt for broader market access including newer assets. All router and fee-taking functionality is open source and runs on user servers, providing transparency and control over the trading infrastructure.

Fynd v0.89.1 now supports propAMMs in routing configurations. **Setup Steps:** - Install via `cargo install fynd` - Set API key: `export TYCHO_API_KEY="<your_tycho_api_key>"` - Launch on Ethereum: `fynd serve --chain Ethereum --protocols all_onchain` - Launch on Base: `fynd serve --chain base --protocols all_onchain` Fynd is an open source routing engine built on Tycho and powered by The Graph Substreams. Support available at tycho.build.

**PropAMMs are now operational** across several decentralized exchanges: - **Fynd.FermiSwap** and **Bebop's BopAMM** launched on mainnet through Titan Builder's infrastructure - Deployment includes **LunarBaseX on Base network** **Key Integration:** KyberSwap became the first DEX aggregator to connect with PropAMMs via [Titan Builder](https://titanbuilder.xyz), offering users: - Improved swap rates through enhanced liquidity access - Better execution at the builder layer - Protection against stale pricing before final block confirmation - Reduced value leakage to market makers **Technical Advantage:** Titan ensures the latest PropAMM quote updates are ranked before swaps execute in each block, providing taker protection and more reliable pricing. FermiSwap has been added as a new liquidity source alongside existing options on KyberSwap's platform.

Trail of Bits has published two comprehensive security audit reports for Propellerheads' Turbine platform: **Frontend + SDK Review** - Examined the user-facing interface and software development kit - [Full report available](https://github.com/trailofbits/publications/blob/master/reviews/2026-03-propellerheads-turbinefrontendsdk-securityreview.pdf) **TEE Backend + Smart Contracts Review** - Assessed the Trusted Execution Environment deployed backend infrastructure - Evaluated associated smart contract implementations - [Full report available](https://github.com/trailofbits/publications/blob/master/reviews/2026-03-propellerheads-turbine-securityreview.pdf) Both audits were conducted in March 2026, with reports published in July. The reviews cover PropellerSwap's liquidity aggregation infrastructure, which routes token swaps across multiple sources while providing MEV protection. Developers and users can review the detailed findings in the published reports to understand the security posture of the platform.

Turbine has published comprehensive security audit reports conducted by Trail of Bits. The full audit documentation is now publicly available, providing transparency into the project's security assessment and findings. This release allows the community and developers to review the security measures and recommendations identified during the auditing process.

Fynd now provides local quotes synchronized with the latest block on Arbitrum, enabling searchers to capture CEX-DEX and DEX-DEX arbitrage opportunities faster. **Key Innovation:** - Rebuilt Tycho's analyzer using `eth_call` and state overrides to bypass Arbitrum Nitro's limitations - Delivers accurate gas estimates without requiring custom nodes - Solves the challenge that Nitro doesn't expose trace methods used by most token analyzers **For Searchers:** Test performance against your current setup using the [benchmarking guide](https://docs.fynd.xyz/guides/benchmarking).

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.
