Abstract: A smart contract is received for a new blockchain transaction and added to a blockchain. The smart contract includes information on a merchant blockchain wallet, a reserve blockchain wallet for the merchant, a dispute blockchain wallet, and a time period. During the time period, when a dispute is lodged by the consumer, the smart contract causes a new transaction to be added to the blockchain that transfers an amount to cover the disputed transaction from the merchant's reserve wallet to the dispute wallet. The dispute is resolved and the dispute resolution added to the blockchain, which causes the smart contract to add another new transaction to the blockchain that either transfers the amount from the dispute wallet back to the merchant's wallet or from the dispute wallet back to the consumer's wallet.

Abstract: A method for enabling refund of a non-fungible token (NFT) includes: receiving a transaction message for a payment transaction; processing the payment transaction using the transaction message, where processing includes identification of a transaction identifier for the payment transaction; transmitting the transaction identifier to a first device; receiving a notification message including the transaction identifier and a token identifier, where the token identifier is associated with the NFT; receiving a refund request message from a second device, where the refund request message includes the transaction identifier and/or the token identifier; processing a refund transaction for the payment transaction; and submitting the transaction identifier as input into a smart contract stored in a blockchain associated with the NFT for reversal of ownership of the NFT.
