To address these limitations, Polygon has emerged as a sidechain solution that facilitates asset transfers between Ethereum and Polygon, thereby improving scalability and reducing costs. However, current cross-chain transactions, particularly those between Ethereum and Polygon, lack transparency and traceability. This paper proposes a method to track cross-chain transactions across EVM-compatible blockchains. It leverages the unique feature that user addresses are consistent across EVM-compatible blockchains. We develop a matching heuristic algorithm that links transactions between the source and target chains by combining transaction time, value, and token identification. Applying our methodology to over 2 million cross-chain transactions (August 2020\u2013August 2023) between Ethereum and Polygon, we achieve matching rates of up to 99.65% for deposits and 92.78% for withdrawals, across different asset types including Ether, ERC-20 tokens, and NFTs. In addition, we provide a comprehensive analysis of various properties and characteristics of cross-chain transactions. Our methodology and findings contribute to a better understanding of cross-chain transaction dynamics and bridge performance, with implications for improving bridge efficiency and security in cross-chain operations.<\/jats:p>","DOI":"10.5195\/ledger.2025.433","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T18:38:15Z","timestamp":1759430295000},"page":"113-134","source":"Crossref","is-referenced-by-count":4,"title":["Tracing Cross-Chain Transactions Between EVM-Based Blockchains: An Analysis of Ethereum-Polygon Bridges"],"prefix":"10.5195","volume":"10","author":[{"given":"Tao","family":"Yan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuanshan","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Tessone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3176","published-online":{"date-parts":[[2025,10,2]]},"container-title":["Ledger"],"original-title":[],"link":[{"URL":"http:\/\/ledger.pitt.edu\/ojs\/ledger\/article\/download\/433\/325","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ledger.pitt.edu\/ojs\/ledger\/article\/download\/433\/326","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/ledger.pitt.edu\/ojs\/ledger\/article\/download\/433\/325","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T18:38:16Z","timestamp":1759430296000},"score":1,"resource":{"primary":{"URL":"http:\/\/ledger.pitt.edu\/ojs\/ledger\/article\/view\/433"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,2]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5195\/ledger.2025.433","relation":{},"ISSN":["2379-5980"],"issn-type":[{"value":"2379-5980","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,2]]}}}
