Functions
@spec __default_address__() :: nil
Default address of the contract. Returns nil
if not specified.
To specify a default address see Ethers.Contract
@spec approve(Ethers.Types.t_address(), non_neg_integer()) :: Ethers.TxData.t()
Prepares approve(address to, uint256 tokenId)
call parameters on the contract.
This function can be used for a transaction or additionally called for results (Use Ethers.send/2
).
No amount of Ether can be sent with this function.
