I am trying to identify the specific blockchain where a smart contract has been deployed using its deployment address. However, I am unable to find a clear source or method for doing so.
When I looked up the address-associated transactions using blockchain explorers, I found them listed on three different blockchains: Etherscan, Polygon Test Explorer, and BNB Testnet Explorer. This is confusing, as I expected the contract to be deployed on one specific blockchain.
Can anyone guide me on how to accurately determine the blockchain where the smart contract has been deployed?
