Vasileios Xouris contributed to the Uniswap/sdks repository by building and integrating multi-chain support, including Unichain and Monad testnet environments, and improving pricing accuracy across SDKs. He implemented cross-version blockchain integration by updating chain IDs, contract addresses, and wrapped token configurations, using TypeScript and JavaScript to ensure seamless SDK and router interoperability. Vasileios addressed critical bugs by aligning deployment details and dependencies, reducing routing errors and price impact miscalculations. His work focused on dependency management, smart contract integration, and version control, resulting in more reliable trade execution and streamlined onboarding for developers working with Uniswap’s evolving multi-chain infrastructure.
January 2026: Focused on delivering pricing accuracy improvements by upgrading core SDKs and aligning dependencies across router-sdk and universal-router-sdk in the Uniswap/sdks repo. Implementations completed via targeted dependency bumps to ensure consistent v4-sdk versions, reducing price impact miscalculations and stabilizing trade pricing for downstream integrations.

November 2025: Fixed a critical bug in Uniswap/sdks by updating the CELO UniversalRouterVersion.V2_0 address and its creation block in the constants to reflect the latest deployment details. This prevents routing errors and maintains compatibility with the latest Universal Router SDK, reducing deployment drift and support burdens. Commit 60fb2f07c34c2e286a5d17be3ce17d03b67728eb (PR #434).

January 2025 monthly summary for Uniswap/sdks: Implemented Monad testnet support by integrating V2 factory, V2 router, and V3 contract addresses, enabling the SDK to interact with the Monad testnet environment. Introduced a new Monad testnet wrapped token to support token operations on Monad. This work lays the foundation for Monad-focused development and testing within the SDK. Relevant commit: 1665d063988c97f72cc98d08e436c717726d98ca (feat(sdk-core): Monad testnet addresses (#240)).

Month: 2024-11 | Focused on expanding Unichain support across the Uniswap SDKs and routing stack. Delivered cross-version (v2/v3/v4) Unichain integration for mainnet and testnet, including new chain IDs, contract addresses, WETH configurations, and the necessary SDK version bumps to enable Unichain across the SDKs and routers. This work establishes multi-chain readiness, reduces future integration effort, and positions Unichain users to access Uniswap liquidity with consistent UX across networks.
