Notes
- Only transfers involving contracts identified as ERC-20, ERC-721, ERC-1155, or native ETH are emitted; unrecognised contracts are skipped.
- A single transaction may produce rows with different
transfer_typevalues (e.g. a native ETH send that also triggers an ERC-20 transfer internally). trace_addressis populated only fornative_internalrows;log_indexis populated only forerc20,erc721, anderc1155rows.
