Over six months, Nillo developed and enhanced core blockchain tooling in the kadena-community/kadena.js and kadena-io/kadena-evm-sandbox repositories. He built wallet adapters, expanded SDK features, and improved CLI support for Kadena smart contracts, focusing on developer experience and cross-wallet interoperability. Using TypeScript, React, and Solidity, Nillo implemented robust API integrations, end-to-end EVM testing, and comprehensive documentation updates. His work included adding ERC-20 deployment tests, integrating Chainweaver and Zelcore wallets, and refining error handling and onboarding flows. The depth of his contributions ensured more reliable contract development, streamlined onboarding, and improved test coverage, directly supporting developer productivity and product maintainability.

June 2025: Delivered a major expansion of the Kadena EVM Sandbox Testing Suite to improve developer experience and contract compatibility. Implemented end-to-end tests including ERC-20 deployment scenarios, CryptoZombies contract interaction, invalid transaction scenarios, and oversized contract deployment checks. Updated dependencies, added new test files, and performed targeted test maintenance to ensure long-term stability. This work reduces integration risk, accelerates contract verification, and strengthens the overall Kadena EVM testing capability.
