1. A method for expedited electronic check (e-check) processing at a universal clearance platform having an integrated distributed hash table, the method comprising:
uploading a biometric marker and e-check data to the clearance platform;
minting the biometric marker as a first non-fungible token (NFT) and the e-check data as a second NFT;
inserting the first NFT and second NFT as a key-value pair in the distributed hash table, wherein the key is the first NFT comprising the biometric marker and the value is the second NFT comprising the e-check data;
validating the biometric marker key against previously captured biometric information;
mapping a key first NFT comprising the validated biometric marker key to a value second NFT comprising the e-check data value via an overlay network associated with the distributed hash table;
validating the e-check data against a previously captured transaction history to clear the e-check; and
in response to e-check clearance, routing the e-check data to the ACH automated clearing house (ACH) network to complete the transfer.
