implementation

during blockchain deposit daemon, WalletService asks its Adapter (by passing The relevant deposit wallet) that the prepare_deposit_collection! method was implemented or not.
if not, the daemon kept continues its process, but if that method existed in the coin Adapter, the deposit daemon call the collect_fee method on the deposit DB record.

collect_fee function

1. Check the spread column of the deposit to find was filled or not. if not call spread_between_wallets! from the Deposit model.
2. Active relevant fee wallet will be found from DB. if not found, we will back to the deposit daemon process.
3. Create WalletService object by passing active fee wallet and run deposit_collection_fees! method on the deposit record.
4. deposit_collection_fees method, run prepare_deposit_collection
5. prepare_deposit_collection method will have a unique implementation for each coin (blockchain),but eventually, the output must be a transaction that in addition to sending into the relevant blockchain, also will be saved in the local DB.
6. Change the state column of the deposit record from processing to fee_processing
