Hello, I'm trying to get some collection metadata from alchemy, and I'm not sure if everything is retrievable via api. Metadata consists of the fields i'm seeing on a collection in opensea: Total Volume, Floor Price, Best Offer, % listed, number of owners , % of unique owners, total supply, creator earnings % and category (like pfps, art etc) I managed to get a few of these: - `floor price`, `total supply` , by using the `/getContractMetadata` method - `number of owners`, by using `/getOwnersForCollection` - `% of unique owners` by using the `total supply` and the data from `/getOwnersForCollection` I'm not sure how to get the `Total Volume`, `Best Offer`, `% Listed`, `Creator Earnings %`, and the nft `Category` - are these obtainable somehow via the Alchemy API ?

Do [Reinforced Transactions](https://docs.alchemy.com/reference/reinforced-transactions) support transactions sent concurrently? e.g. if I send transaction 1 and then transaction 2 (from the same sender address) before transaction 1 has been confirmed, will both be successfully confirmed or will there be nonce clashes?

Does [Reinforced Transactions](https://docs.alchemy.com/reference/reinforced-transactions) use [ERC2771](https://eips.ethereum.org/EIPS/eip-2771) meta-transactions using trusted forwarders?

How can I retrieve my old apps once I join a team in Alchemy?

What will happen if I join a team with my Alchemy account?

Is there a way to get the chain that a collection (or an asset from a collection) belongs to? meaning i have the contract address of the collection, and i want an output like "Ethereum", or "Polygon" etc

I need to know how many addresses I can add to a Webhook?

Hi, I am trying to query the `getContractMetadata` function for a certain NFT collection address but I keep seeing `tokenType`:`UNKNOWN` in the response even though it is an ERC721 collection. What is the reason and what can I do to fix this?

Now, I have deployed several NFT collections to Celo mainnet and Celo testnet(Alfajores). I am going to fetch all data of NFT like other chains - Ethereum, Polygon...
