Systems and methods are provided for generating and managing dynamic customized electronic tokens for electronic device interactions. A system for transferring data between a user device associated with a user and a remote device may include a memory storing instructions and a processor configured to execute the stored instructions. The stored instructions may configure the processor to receive, via a network, transaction information from the remote device, access information associated with an electronic token, and provide the electronic token to the remote device. The electronic token may be associated with at least one of the user or the user device, and a token server may generate the electronic token based on the received transaction information, and determine one or more expiration parameters for the electronic token.

A method for propagating survival of cryptographic currency after inactivity over a predetermined period of time in a blockchain through the use of smart contracts includes: receiving a propagation request that includes unspent transaction output addresses, a digital signature, and a recipient address; generating a smart contract that is configured to self-execute after a predetermined period of time to initiate transfer of cryptographic currency from the output addresses to the recipient address; submitting the smart contract to a node in a blockchain network for addition to the blockchain; monitoring for new blockchain transactions involving any of the unspent transaction output addresses; generating a new smart contract to update the unspent transaction output addresses based on new blockchain transactions; and submitting the new smart contract to a node in a blockchain network after updating.

Methods, systems, and apparatus, including computer program products, in which a method includes attributing a value to a pre-paid payment instrument, determining an expiration time associated with the pre-paid payment instrument, and automatically return an un-used portion of value associated with the pre-paid payment instrument at the expiration time to the purchaser.

Methods, apparatus, systems, and computer program products are disclosed for utilizing specially configured machine learning models to generate incremental currency value(s) associated with one or more target merchant data objects. Some embodiments, based on one or more market record sets, identify an actual electronic currency value for a total merchant data object set, and include a counterfactual model configured to generate a counterfactual electronic currency value for use in determining a counterfactual incremental electronic currency impact, and in some embodiments for ranking other models. Embodiments, additionally or alternatively, include an incrementality-trained ensemble model for generating a predictive incremental electronic currency impact. The incrementality-trained ensemble model may be trained to predict based on the rankings of the outputs of the counterfactual model. Embodiments may further rank target merchant data objects and perform one or more additional actions, including assigning the target merchant data objects to sales account data structures for management.

Systems and methods for gasless decentralized token swaps with MEV protection are disclosed herein. A user submits to a swap platform a signed limit order to swap an amount of input token for an output token using a Dutch auction approach. The order execution price depends on time of inclusion in a block and decreases over the duration of the Dutch auction. The user does not pay a gas fee for submitting this order. The swap platform provides the order details to whitelisted resolvers to evaluate if/when/how to fill the order. Once a resolver makes that determination, it can send instructions and fill data to smart contracts of the swap platform to fill the order and implement the swap. Input tokens are pulled from the user's wallet and transferred to the resolver, in exchange for output tokens which are pulled from the resolver and transferred to the user's wallet.
