Abstract

In some examples, a system or method of implementing a smart contract on a blockchain can involve receiving an indication of a portfolio of assets, an amount from a buyer to invest in the portfolio, a number of assets in the portfolio that is based on exchange rates and the amount to invest, and a confirmation from the buyer of the number of assets. The system or method can involve calculating a cost of the portfolio to yield a contract, receiving the amount and excess collateral from the buyer as a buyer acceptance of the contract, and an entity acceptance of the contract including an entity amount. The system or method can involve receiving, at the smart contract, a request from the buyer to close the contract, and settling the contract via the smart contract at a current value of the portfolio based on pricing data from a valuation entity.
