## Abstract

Systems and methods for distributed ledger-based intraday trading are disclosed. In one embodiment, a method may include: receiving a digital representation of an amount of collateral for a cash borrower; receiving a digital representation of an amount of cash for a cash provider; receiving agreement from the cash borrower and the cash provider to terms of an intraday trade comprising a duration of the intraday trade, a collateral trade amount of the collateral, and a cash trade amount of cash; a smart contract executing the intraday trade by providing the trade amount of the digital collateral to the cash provider and the cash trade amount of the digital cash to the cash borrower; and the smart contract returning the trade amount of the digital collateral to the cash borrower and the cash trade amount of the digital cash to the cash provider at the completion of the intraday trade.

## Claims

### Claim 1

A method for distributed-ledger based intraday trading, comprising
in an information processing apparatus comprising at least one computer processor:
receiving, at a first distributed ledger and from a cash borrower digital wallet on a second ledger, a digital representation of an amount of a collateral for a cash borrower, wherein the collateral that is digitally represented on the first distributed ledger is ringfenced or locked by a collateral custodian;
receiving, at the first distributed ledger and from a cash provider digital wallet on the second ledger, a digital representation of an amount of cash for a cash provider;
receiving, at the first distributed ledger, agreement from the cash borrower and the cash provider to terms of an intraday trade comprising a duration of the intraday trade, a collateral trade amount of the digital representation of the collateral, and a cash trade amount of the digital representation of the cash;
a smart contract executed by the first distributed ledger orchestrating the intraday trade by:
automatically providing the collateral trade amount to the cash provider digital wallet and the cash trade amount to the cash borrower digital wallet;
writing a first change in ownership for the cash trade amount and the collateral trade amount to the first distributed ledger;
automatically returning the collateral trade amount of the digital representation of the collateral to the cash borrower digital wallet and the cash trade amount to the cash provider digital wallet at an expiration of the intraday trade; and
writing a second change in ownership for the cash trade amount and the collateral trade amount to the first distributed ledger.

### Claim 2 (depends on 1)

The method of claim 1, wherein the amount of cash that is digitally represented on the first distributed ledger is separated from other cash by a cash bank.

### Claim 3 (depends on 1)

The method of claim 1, wherein the amount of collateral that is digitally represented on the first distributed ledger is the same as the collateral trade amount.

### Claim 4 (depends on 1)

The method of claim 1, wherein the amount of cash that is digitally represented on the first distributed ledger is the same as the cash trade amount.

### Claim 5 (depends on 1)

The method of claim 1, wherein the duration of the intraday trade is one of minutes or hours.

### Claim 6 (depends on 1)

The method of claim 1, wherein the collateral comprises a security.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
verifying that the digital representation of the collateral is sufficient for the collateral trade amount; and
verifying that the digital representation of the cash is sufficient for the cash trade amount.

### Claim 8

A method for distributed-ledger based intraday trading, comprising
in an information processing apparatus comprising at least one computer processor:
receiving, at a first distributed ledger, agreement from a cash borrower and a cash provider to terms of an intraday trade comprising an expiration of the intraday trade, a collateral trade amount of a collateral, and a cash trade amount of cash;
receiving, at the first distributed ledger and from a cash borrower digital wallet on a second ledger, a digital representation of the collateral trade amount for a cash borrower, wherein the collateral that is digitally represented on the first distributed ledger is ringfenced or locked by a collateral custodian;
receiving, at the first distributed ledger and from a cash provider digital wallet on the second ledger, a digital representation of the cash trade amount for a cash provider;
a smart contract executed on the first distributed ledger orchestrating the intraday trade by:
automatically providing the collateral trade amount to the cash provider digital wallet and the cash trade amount to the cash borrower digital wallet;
writing a first change in ownership for the cash trade amount and the collateral trade amount to the first distributed ledger;
automatically returning the collateral trade amount to the cash borrower digital wallet and the cash trade amount to the cash provider digital wallet at the expiration of the intraday trade; and
writing a second change in ownership for the cash trade amount and the collateral trade amount to the first distributed ledger.

### Claim 9 (depends on 8)

The method of claim 8, wherein the cash trade amount of cash is separated from other cash by a cash bank.

### Claim 10 (depends on 8)

The method of claim 8, wherein a duration of the intraday trade is one of minutes or hours.

### Claim 11 (depends on 8)

The method of claim 8, wherein the collateral comprises a security.
