# `__default_address__`

```elixir
@spec __default_address__() :: nil
```

Default address of the contract. Returns `nil` if not specified.

To specify a default address see `Ethers.Contract`

# `balance_of`

```elixir
@spec balance_of(Ethers.Types.t_address(), non_neg_integer()) :: Ethers.TxData.t()
```

Prepares `balanceOf(address account, uint256 id)` call parameters on the contract.

This function should only be called for result and never in a transaction on its own. (Use `Ethers.call/2`)

State mutability: `view`

## Function Parameter Types
 - account: `:address`
 - id: `{:uint, 256}`

## Return Types (when called with `Ethers.call/2`)
 - `{:uint, 256}`

# `balance_of_batch`

```elixir
@spec balance_of_batch([Ethers.Types.t_address()], [non_neg_integer()]) ::
  Ethers.TxData.t()
```

Prepares `balanceOfBatch(address[] accounts, uint256[] ids)` call parameters on the contract.

This function should only be called for result and never in a transaction on its own. (Use `Ethers.call/2`)

State mutability: `view`

## Function Parameter Types
 - accounts: `{:array, :address}`
 - ids: `{:array, {:uint, 256}}`

## Return Types (when called with `Ethers.call/2`)
 - `{:array, {:uint, 256}}`

# `constructor`

```elixir
@spec constructor() :: binary()
```

Prepares contract constructor values for deployment.

To deploy a contracts use `Ethers.deploy/2` and pass the result of this function as
`:encoded_constructor` option.

## Parameters
