Check If Address Exists on Other Chains
1. Overview & Typical Use
Checks whether a TRON address also exists on other blockchain networks (such as BitTorrent Chain), and returns the corresponding address and explorer links on each chain.
- Typical use: cross-chain address association, multi-chain asset discovery, address information enrichment.
- When not to use: to query detailed account information, use “Get Account Detail”; to query account token holdings, use “Get Account Token List”.
