A function to call the dummy ERC20 contract and store a trade.
Parameters:
contract_address (str): address of the deployed contract,
e.g. 5DvtpRYA3hWCwhW3NrrVJCNZinYgSy4W2Sgg38SYkv62LUpQ
trade_id (str): a number between 00 and 63 representing a trade ID in hex (e.g. 10 = 0a).
seed_phrase (str): a string of 12 words to restore a Polkadot account.
value_to_contract (str): the value sent to the contract within this transaction (0 in this case).
gas (str): the maximum allowed gas for this transaction.
fid (str): the hex representation of the function, generated in the metadata.
