PROFILE

Melisa Guevara

Melissa Guevara contributed to the across-protocol/frontend and sdk repositories by building robust cross-chain swap and liquidity features, focusing on Solana and EVM interoperability. She engineered integrations such as Jupiter DEX and CCTP bridge, enabling Solana-to-EVM routing and native USDC transfers, while enhancing token data enrichment and swap reliability. Using TypeScript, JavaScript, and Solidity, Melissa implemented recursive API validations, event tracking, and dynamic configuration management to reduce runtime errors and improve data accuracy. Her work addressed complex backend and frontend challenges, including fee calculation, chain mapping, and event parsing, resulting in deeper cross-chain functionality and more resilient, maintainable codebases.

Work History

October 2025

6 Commits • 3 Features

Oct 1, 2025

Delivered cross-chain token data enrichment, OFT and CCTP bridge enhancements, and targeted bug fixes for across-protocol/frontend, driving improved data accuracy, cross-chain interoperability, and end-user experience. Key contributions include Solana token data enrichment for /swap/tokens, OFT bridge strategy with fee exposure, Solana-origin support for CCTP, and fixes to indirect chain mapping and Solana recipient derivation.

Sep 1, 2025

September 2025 monthly summary for across-protocol/frontend: Delivered cross-chain liquidity enhancements and reliability improvements that drive business value and developer productivity. The work focused on expanding liquidity sources, improving route reliability, and sharpening observability across cross-chain swaps. Key outcomes include: Jupiter DEX integration with SVM-enabled A2B transfers enabling Solana-to-EVM routing; Lens network restoration and swap-route fixes to ensure Solana availability; re-enabled Linea network to restore full Linea functionality; CCTP bridge integration for native USDC cross-chain transfers with quoting and transaction-building support; and performance/observability improvements (reduced RPC usage, enhanced swap test visibility) along with a corrected A2B fee calculation. These changes collectively broaden liquidity sources, reduce latency, improve quote accuracy, and enhance observability across cross-chain swaps.

August 2025

Aug 1, 2025

August 2025 monthly summary focusing on business value, reliability, and cross-chain capabilities. Major work centered on cross-chain swap enhancements via embedded actions and a robust swap API, Solana gas price support with a unified UX, and targeted maintenance to stabilize integration work. Key fixes improved swap request handling, body parsing, and output accuracy, while a maintenance decision temporarily disabled Lens integration to reduce risk and unblock planned work across environments. Overall impact: strengthened multi-chain swap reliability, improved output correctness and balance handling, and delivered a unified transaction view that supports faster decision-making for users and business stakeholders.

Jul 1, 2025

July 2025 (2025-07) performance summary for across-protocol/frontend. Key focus this month was delivering robust swap-related validations and stabilizing essential network integrations to maintain reliable on-chain operations and improve developer experience. The work directly supports safer swap execution, reduces runtime failures due to ABI encoding issues, and restores stable Polygon connectivity, enabling continued growth and reliability of the platform.

June 2025

4 Commits • 2 Features

Jun 1, 2025

June 2025: Delivered robust event-tracking enhancements and API usability improvements for across-protocol/sdk, alongside a critical validation bug fix. This month focused on event processing resilience, developer experience, and code quality to accelerate future feature delivery and reduce production risk.

May 2025

2 Commits • 1 Features

May 1, 2025

May 2025 monthly summary: Delivered user-facing deposits capability on app.across.to and improved core data integrity. The frontend activation of the deposits endpoint enables deposits for users via routing/feature flag changes, while the SDK fix ensures SVM event chain IDs are parsed as Numbers, reducing downstream errors and improving analytics reliability. This work strengthens cross-repo collaboration and sets the stage for broader deposits-enabled features.

March 2025
