DvP for CMTA

The DvP (Delivery versus Payment) smart contract (DVP.sol) interacts with an Asset Token smart contract (Delivery) and a Payment Order Token smart contract (Payment).

The task of the DvP is to

• receive the Payment Order Token
• transfer the Asset Token(s) from the wallet of the seller to itself
• initiate the payment promised by the POT and
• after receiving the confirmation of payment, sending the AT to the wallet of the buyer

Asset Token

DVP.sol can interact with any smart contract that implements the IERC20Upgradeable interface, e.g. CMTA's CMTAT contract.

Payment Order Token

targens provides a IERC721-compliant Payment Order Token (Interface: src/solidity/contracts/POT/IPOT.sol) that is agnostic of other contracts, except for the OpenZeppelin ones and logging support.
