Abstract: Technology for automated investing and divesting of the assets using a blockchain ledger may receive first event data reflecting a divestment event associated with an account of a user. The divestment event includes a transaction value in a base currency. The technology may retrieve, from a database, a diversification setting associated with the user; determine, based on the diversification setting and the transaction value, a first amount of an asset to divest; access, via a network, a blockchain ledger to verify, using a unique identifier associated with the user and an asset identifier identifying the asset, that the first amount of the asset to divest is available; process a first exchange of the first amount of the asset for a first corresponding amount of the base currency; and record, in the blockchain ledger using the unique identifier associated with the user, that the first amount of the asset was divested.
