Parameters

1. owner (address as hex string, default: 0x000a22cdb94efbb7260ad038e1b2d377d950ed78)
   1. The owner for which we want to check their portfolio.
2. chain_id (uint64, default: 0)
   1. Optional. Can be used to view balances from a certain chain. If unset, defaults to 0 and returns results from all chains.
3. token_address (address as hex string, default: 0x0000000000000000000000000000000000000000)
   1. Optional. Can be used to filter results to a specific token. If unset, defaults to address(0) and all tokens are checked.
4. block_number (uint64, default: 0)
   1. Optional. Can be used to view allowances at a particular block. If unset, defaults to 0 and returns latest.
5. limit (uint32, default: 100)
   1. Number of records you want returned.
6. offset (uint32, default: 0)
   1. For pagination. If you're showing ten records per page, choose offset = 9 for the second page.

Returns

Array with the following fields:

1. owner (address as hex string)
   1. The owner for which we checked the portfolio.
2. chain_id (int64)
   1. The chain for the token
3. token_address (address as hex string)
   1. The token's address.
4. token_name (string)
   1. The token's name.
5. token_symbol (string)
   1. The token's symbol.
6. is_for_all (bool)
   1. true for operator approvals (setApprovalForAll) and false for token-specific approvals (approve). See table usage notes.
7. operator(address as hex string)
   1. The operator's address for operator approvals, else address(0).
8. token_id (int256 as decimal string)
   1. The token's id for token-specific approvals, else 0.
9. approved_address (address as hex string)
   1. The approved address for token-specific approvals, else address(0).
10. txn_last_changed (address as hex string)
    1. The most recent transaction that impacted the approval. Note that this will include ERC721 transfers, which reset approvals (even if none was set).
11. block_last_changed (int64)
    1. The most recent block that impacted the approval.

The array is sorted in descending order of block_last_changed.
