Worked on enhancing escrow protection within the LayerZero-Labs/devtools repository by implementing stricter controls in the Aptos OFT adapter using the Move language. The approach involved disowning the escrow object to prevent unauthorized withdrawals, directly addressing a critical security concern in blockchain-based financial flows. To ensure reliability, a regression test was added to verify that escrow transfers fail as intended, improving test coverage and reducing the risk of future regressions. Additionally, unused OApp compose modules were removed to streamline code maintenance and reduce technical debt. The work demonstrated a focus on blockchain development, smart contracts, and maintainable, secure code.
