# Smart Contract Infrastructure

The second layer of the PGN architecture is its smart contract infrastructure. This layer consists of a series of blockchain-based contracts that facilitate various transactions within the network, such as the minting and burning of Cyphers, redemption of physical gold and participation in liquidity services. These smart contracts are programmed to execute automatically based on predefined conditions, ensuring transparency, efficiency, and trust in all transactions. The smart contract layer enables the digital representation of physical gold through Cyphers, allowing users to easily manage and use their gold holdings in a secure digital environment.
