Get smart contract transfer history (Eth/Poly)?

General

I see we have qn_getTransfersByNFT RPC Method | Ethereum Documentation

Is there a way to get transfers of the smart contract itself instead of for a specific NFT? I tried to just omit the tokenId but that comes in as malformed.

Want to be able to see all transfers of a eth/poly smart-contract to determine all past/present owner wallets of said smart-contract

Hey Llama,

The GraphAPI would be better suited for this. The Graph API enables you to do deeper custom queries on data.

query Ethereum($contractAddress: String!) {
  ethereum {
    contract(contractAddress: $contractAddress) {
      tokenEvents {
        totalCount
        pageInfo {
          endCursor
          hasNextPage
          hasPreviousPage
        }
        edges {
          node {
            ... on TokenTransferEvent {
              blockNumber
              transactionHash
              transferIndex
              timestamp
              type
              fromAddress
              toAddress
              from {
                address
              }
              to {
                address
              }
              transaction {
                hash
              }
              contractAddress
              contractERCStandard
              tokenId
              tokenQuantity
              
            }
          }
        }
      }
    }
  }
}

Appreciate you Nick. Gonna take a look at the graph api, that definitely seems like the right direction.

Of note, I think your request gets tokenTransfers whereas I’m looking for contract ownership transfers/information. Ex: Wallet-address-A created a 721||1155 contract => Wallet-address-A transferred contract ownership to Wallet-address-B

Hey Llama,

You may find qn_fetchNFTCollectionDetails (v2) RPC Method | Ethereum Documentation useful because it returns genesisTransaction which you can then use to lookup details like what wallet initiated the contract.

Calling owner on the contract would give the current owner’s address. We don’t currently index ownership transfers.

If those events are of interest in real-time, you may utilize QuickAlerts to listen for OwnershipTransferred events on smart contracts. Not all contracts follow the same conventions, but many do.
