Metal is a blockchain-based system utilizing Proof-of-Processed-Payments to identify users, rewarding them for converting legacy fiat currency into cryptocurrency, acting as a bridge to the cryptocurrency world. Metal's system uses provable payments attached to verified identities to distribute currency. Anyone can participate to earn METAL as a reward for converting fiat to cryptocurrency. The Metal project aims to provide all of the financial services small to medium sized businesses (SMB) might need.

The MTL token is the native currency within the Metal system and it's distributed through a Proof of Processed Payments (PoPP) in which users earn MTL for sending money or making purchases.
