• for each said service option initiation message, save in a service option database a database record comprising the service option identifier in association with the service option value;
• receive at least one service option authorization message from the second computer server, each said service option authorization message including one of the service option identifiers and an authorization value;
• for each said service option authorization message, validate one of the service option initiation messages and update the service option database with a confirmation database entry, the confirmation database entry comprising the one service option value and confirming validation of the one service option initiation message, the validate the one service option initiation message comprising (i) locating in the service option database the database record comprising the one service option identifier, and (ii) confirming that the service option value in the located database record matches the authorization value;
• receive at least one ledger update request from one of the computer servers, one of the ledger update requests including the one service option identifier, and validate the one ledger update request by (i) locating in the service option database the database record comprising the one service option identifier, and (ii) confirming that the located database record includes the confirmation database entry;
• determine a first transfer amount, and effect a first transfer from a first institution ledger to a first customer ledger in an amount equal to the first transfer amount, the effect a first transfer comprising transmitting to the first computer server a ledger update authorization comprising the transfer amount;
• update a settlement journal with a settlement journal entry identifying a settlement transfer between the first institution ledger and a second institution ledger in an amount equal to a sum of the service option values of the validated service option initiation messages;
• and
• provide the first computer server with a settlement message confirming the settlement transfer.
