Auto installments via smart contracts on blockchain

A method, comprising:

• receiving registered accounts of a user from a provider that services installment payments due from the user to a creditor;
• providing the provider a secure token for delivery to a user and creation of a smart contract that manages the installment payments on a blockchain;
• receiving the secure token from the user and linking the secure token to the registered accounts;
• receiving selections from the user that designate a default account and secondary accounts from the registered accounts;
• generating a first access token associated with the default account and a second access token associated with the secondary accounts;
• configuring instructions with conditions associated with the installment payments, the default account, the secondary accounts, the first access token, and the second access token;
• instantiating the instructions on the blockchain as a smart contract that is reachable by the provider on the blockchain via the secure token and that manages the installment payments using the conditions, the first access token, and the second access token.

A system, comprising:

• a server comprising at least one processor and a non-transitory computer-readable storage medium;
• the non-transitory computer-readable storage medium comprises server executable instructions;
• the executable instructions when executed by the at least one processor from the non-transitory computer-readable storage medium cause the at least one processor to perform operations comprising:
• linking registered accounts of a user to a secure token;
• identifying a default account from the registered accounts;
• identifying remaining accounts that are not the default account as secondary accounts;
• generating a first access token associated with the default account;
• generating a second access token associated with the secondary accounts;
• configuring instructions for a smart contract to manage installment payments made by the user through the registered accounts to a provider who collects the installment payments on behalf of a creditor of the user;
• configuring the instructions to link the first access token to the default account and the second access token to the secondary accounts;
• and
• installing and initiating the instructions as a smart contract on a blockchain accessible on the blockchain via the secure token, wherein the smart contract transfers funds for a particular installment payment from the default account of the user to an account associated with the provider or the creditor when a current balance of the default account is sufficient to cover the particular installment payment otherwise the smart contract apportions amounts from the registered accounts to cover the particular installment payment and transfers the corresponding amounts from the registered accounts to the account associated with the provider or the creditor.
