System and method for trust-minimized real-time value-exchange and liquidity replenishment

A method for trust-minimized real-time inter-chain value-exchange between a source token and a destination token comprising:

• providing a real-time trust-minimized value exchange rail communicatively coupled to a payment services provider via a network, wherein:
• the real-time trust-minimized value exchange rail comprises:
• a unified trust-minimized exchange subsystem further comprising:
• an off-chain trusted API communicatively coupled to:
• a first interchain router and a second interchain router, and
• a first smart contract and a second smart contract,
• wherein:
• the first smart contract is associated with a source chain and comprises a first vault,
• the second smart contract is associated with a destination chain and comprises a second vault,
• the first interchain router is associated with the first smart contract and communicatively coupled to a source decentralized exchange (DEX) associated with the source chain, and
• the second interchain router is associated with the second smart contract and communicatively coupled to a destination DEX associated with the destination chain;
• receiving, by the real-time trust-minimized value exchange rail, a transaction order from the payment services provider;
• based on the receiving, initiating, by the off-chain trusted API, a debit swap of an amount of the source token to an amount of source stablecoin using the first interchain router and the source DEX,
• the debit swap further comprising directing the amount of the source token to the source DEX from a source cryptocurrency address,
• converting the amount of the source token into the amount of the source stablecoin via the source DEX, and
• facilitating, by the first smart contract, the storage of the amount of source stablecoin in the first vault;
• monitoring, by the off-chain trusted API, an on-chain process associated with the source DEX to determine a validation status of the debit swap;
• receiving, by the off-chain trusted API, information related to the transaction order comprising a first value corresponding to the amount of source stablecoin;
• and
• when the off-chain trusted API determines the debit swap is being validated, initiating, by the off-chain trusted API, a credit swap, wherein the initiating comprises:
• performing a transaction call on the second smart contract, comprising:
• the off-chain trusted API transmitting the first value to the second smart contract,
• the credit swap further comprising:
• directing, by the second interchain router, an amount of destination stablecoin corresponding to the first value from the second vault to the destination DEX for conversion into an amount of the destination token, and
• directing, by the second interchain router, the amount of the destination token to a destination cryptocurrency address communicatively coupled to the real-time trust-minimized value exchange rail, and
• further wherein at least some part of the debit swap and credit swap occur in parallel.
