A method for automatic initiation of a blockchain transaction with a pre-approved recipient includes: receiving at least a recipient identifier and a transaction amount; performing a validation process to validate that (i) the recipient identifier is pre-approved by a user of the computing device for blockchain transactions, and (ii) the transaction amount is beneath a predetermined amount limit for blockchain transactions; generating a new blockchain transaction including at least the recipient identifier, the transaction amount, and one or more source addresses; digitally signing the new blockchain transaction using a private key of a first cryptographic key pair stored in a memory of the computing device; and transmitting the digitally signed new blockchain transaction to a blockchain node in a blockchain network.

A method for mediating an atomic swap includes: receiving a swap request from a first computing device including a first address associated with a first blockchain and a network identifier associated with a second blockchain; identifying a second computing device using the network identifier and a second address associated with the second blockchain; generating a proof value and a hashlock using the proof value; transmitting (i) the hashlock and second address to the first computing device, and (ii) the hashlock and first address to the second computing device; verifying a first blockchain transaction on the first blockchain for transfer to the first address, and a second blockchain transaction on the second blockchain for transfer to the second address; and transmitting the proof value to blockchains node associated with the first and second blockchains.
