These are top level ethereum transactions that occur with a from address being an external (user created) address. External addresses have private keys and are accessed by users.
Event logs for ERC20 transfers.
Event logs for ERC721 transfers.
These are event logs for ERC1155 transfers.
These are transfers that occur where the
fromAddress is an internal (smart contract) address. (ex: a smart contract calling another smart contract or smart contract calling another external address).
NOTE: For efficiency, we do not return internal transfers with 0 value as they don't provide useful information without digging deeper into the internal transaction itself. If you are interested in these type of events see our Trace API.
Additionally, we do not include any **internal transfers with call type
delegatecallbecause although they have a value associated with them they do not actually transfer that value (see Appendix H of the Ethereum Yellow Paper if you're curious). We also do not include miner rewards as an internal transfer.
The special NFT endpoint allows users to query for NFTs that don't follow any ERC standards. For instance, 2 included NFTs are CryptoPunks and CryptoKitties which both predate NFT standards.
