Systems and methods for token-based cross-currency interoperability

A computer-based method for conducting a token-based cross-currency transaction comprising:

• receiving, by a first computer program executed by a first financial institution information processing apparatus comprising at least one computer processor and from a first party, a transaction initiation request for sending an amount of a first fiat currency to a second party, the second party receiving an equivalent of the amount in a second fiat currency, wherein the first fiat currency and the second fiat currency are different currencies, wherein the first financial institution participates as a first node of a plurality of nodes in a distributed ledger network;
• deducting, by the first computer program, the amount of the first fiat currency from a first account for the first party, the first fiat currency account being in the first fiat currency;
• converting, by the first computer program, the amount of the first fiat currency into a third fiat currency, the third fiat currency being different from the first fiat currency and the second fiat currency;
• creating, by the first computer program, an amount of tokens for the amount of the third fiat currency and writing the tokens to a first financial institution copy of a distributed ledger in the distributed ledger network, wherein the distributed ledger is cryptographically-verifiable and immutable;
• receiving, by a second computer program for a second financial institution, the tokens from a second financial institution copy of the distributed ledger, wherein the second financial institution participates as a second node of the plurality of nodes in the distributed ledger network;
• converting, by the second computer program, the tokens to the second fiat currency, wherein the tokens are destroyed as a result of the converting;
• wherein a change on first financial institution copy of the distributed ledger or the second financial institution copy of the distributed ledger are reflected on the other copies of the distributed ledger.

A computer-based system for conducting a token-based cross-currency transaction, comprising:

• a first financial institution information processing apparatus for a first financial institution comprising at least one computer processor and executing a first computer program;
• a second financial institution information processing apparatus for a second financial institution comprising at least one computer processor and executing a second computer program;
• and
• a distributed ledger network, wherein the first computer program and the second computer program are in communication with the distributed ledger network and the first financial institution participates as a first node in the distributed ledger network and the second financial institution participates as a second node in the distributed ledger network;
• wherein:
• the first computer program executed receives, from a first party, a transaction initiation request for sending an amount of a first fiat currency to a second party, the second party receiving an equivalent of the amount in a second fiat currency, wherein the first fiat currency and the second fiat currency are different currencies;
• the first computer program deducts the amount of the first fiat currency from a first account for the first party, the first fiat currency account being in the first fiat currency;
• the first computer program converts the amount of the first fiat currency into a third fiat currency, the third fiat currency being different from the first fiat currency and the second fiat currency;
• the first computer program creates an amount of tokens for the amount of the third fiat currency and writing the tokens to a first financial institution copy of a distributed ledger in the distributed ledger network, wherein the distributed ledger is cryptographically-verifiable and immutable;
• the second computer program receives the tokens from a second financial institution copy of the distributed ledger;
• and
• the second computer program converts the tokens to the second fiat currency, wherein the tokens are destroyed as a result of the converting;
• wherein a change on first financial institution copy of the distributed ledger or the second financial institution copy of the distributed ledger are reflected on the other copies of the distributed ledger.

A non-transitory computer readable storage medium, including instructions stored thereon, which when read and executed by one or more computer processors, cause the one or more computer processors to perform steps comprising:

• receiving, from a first party in a distributed ledger network, a transaction initiation request for sending an amount of a first fiat currency to a second party, the second party receiving an equivalent of the amount in a second fiat currency, wherein the first fiat currency and the second fiat currency are different currencies, wherein the first financial institution participates as a first node of a plurality of nodes in a distributed ledger network;
• deducting the amount of the first fiat currency from a first account for the first party, the first fiat currency account being in the first fiat currency;
• converting the amount of the first fiat currency into a third fiat currency, the third fiat currency being different from the first fiat currency and the second fiat currency;
• creating an amount of tokens for the amount of the third fiat currency and writing the tokens to a first financial institution copy of a distributed ledger in the distributed ledger network, wherein the distributed ledger is cryptographically-verifiable and immutable;
• receiving the tokens from a second financial institution copy of the distributed ledger, wherein the second financial institution participates as a second node of the plurality of nodes in the distributed ledger network;
• and
• converting the tokens to the second fiat currency, wherein the tokens are destroyed as a result of the converting;
• wherein a change on first financial institution copy of the distributed ledger or the second financial institution copy of the distributed ledger are reflected on the other copies of the distributed ledger.
