Returns ERC20 token balances for all tokens in which the given address has ever held a position

Parameters

  1. address (address as hex string, default: 0x0000000000000000000000000000000000002c64)
    1. The address for which we want to check the balances.
  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. 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.
  4. limit (uint32, default: 100)
    1. Number of records you want returned.
  5. 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. address (address as hex string)
    1. The address for which we checked the balances.
  2. chain_id (int64)
    1. The chain for the token
  3. token_address (address as hex string)
    1. The address of the token.
  4. token_name (string)
    1. The name of the token.
  5. token_symbol (string)
    1. The symbol of the token.
  6. balance (int256 as decimal string)
    1. The balance at the specified block, normalized using that token's decimals.
  7. txn_last_changed (address as hex string)
    1. The most recent transaction that impacted the balance.
  8. block_last_changed (int64)
    1. The most recent block that impacted the balance.

The array is sorted in descending order of block_last_changed.
