Metal's payment app includes live payment invoicing and full P2P value transfer which is the same as Venmo or PayPal. Metal uses the public Ethereum blockchain. Metal aims to be blockchain agnostic and recognizes the need for multiple cryptocurrencies
Metal also Utilizes a Proof-of-Processed-Payments (PoPP). Proof-of-Processed-Payments (PoPP) acts as a provable way of identifying users and distributing new currency into the system. At the same time, it rewards users who convert fiat currency into cryptocurrency. For this identity-based, volume-dependent distribution network, Metal first identifies a user through a social security number or passport ID with identification software. Second, Metal gets a photograph on file, either a selfie or picture of identifying documents. Third, Metal can link a credit or debit card number in preparation for processing a payment. If no credit/debit card is available, a user can sign up with only an email address and invoice credit/debit/ach accounts into cryptocurrency. Provided all data points check out and the registered name on the identification matches the name on the credit or debit card, Metal initiates a payment using proprietary anti-money-laundering (AML) and anti-fraud technology. The payment typically declines or accepts in under one minute. The pending payment notification shows on the transaction list for the receiver of funds. When the payment is completely settled and the bank transfer or cryptocurrency issued, a portion of the gross amount of the payment is returned in METAL tokens. This is 5% of the volume of the transaction at trading value for MTL in either direction (sender/receiver). As an example, $100 in MTL is sent. It is trading $1/MTL. Both sender and receiver would both receive 5 MTL.
Use of Native tokens in the ecosystem: Metal rewards users with free MTL tokens for spending cash or converting fiat into cryptocurrency (up to 5%) and when they hold their MTL
