Abstract
This paper presents the design, development, and evaluation of an atomic cross-chain escrow system facilitating secure, trustless asset transfers between Ethereum Virtual Machine compatible blockchains, Solana, and The Open Network. Driven by the increasing fragmentation of the blockchain ecosystem and the demand for seamless cross-chain interoperability, this work addresses the limitations of centralized intermediaries and existing bridge solutions. The research involved identifying key challenges in atomic cross-chain escrow development, including differing blockchain architectures and HTLC concept and its core principles. As a core contribution, three distinct smart contracts were engineered, one for each target blockchain (EVM, Solana, and TON), to enable a hash-time-locked escrow mechanism. The developed contracts were evaluated for security and efficiency, demonstrating the feasibility of achieving guaranteed fund delivery or refund across these disparate networks without reliance on a trusted third party.
