With the , we can only have one logic or implementation smart contract. However, there are cases when we want to have one proxy with more than one logic smart contract. In this case, we need the diamond proxy pattern, which is also known as the multi-facet proxy pattern.
After verifying your proxy smart contract and its logic (implementation) smart contract, you can execute the functions via FTMScan. However, like the other EVM explorers, such as Etherscan, FTMScan can’t support a verified diamond proxy and its logic smart contracts, also known as facets. Fortunately, now we have a diamond inspector called which also supports the Opera mainnet and testnet.
Here are two samples of a diamond proxy and its facets which can be inspected using Louper:
