Collection Total Volume and other metadata
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 ?

Concurrent Transactions in Reinforced Transactions: Handling Nonce Clashes
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?

tokenType is Unknown in Alchemy NFT API response
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?

Does Alchemy support Celo chain?
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...
