Hi. I am using hardhat upgrades plugin to deploy my proxy, proxy admin and implementation contract. Afterwards, I use a script to extract the addresses of all the deployed contracts from the generated rinkeby.json file into a separate file. Under the "impls" field, I do not understand what's the first field which is a very long address b0beb24c340350c72510cfb042b4f6509cf9f8998aab5b2eb3d142006c3c8aab. Here is a screenshot of my rinkeby.json file.
Hi @Maham_Zaidi,
That string is a version identifier used by the upgrades plugins to identify different versions of implementation contracts. It is a hash of the implementation contract's init bytecode, so any changes to the implementation contract logic would result in a different version identifier.
