Abstract: A method for facilitating permission-based cryptographic transactions across service providers includes: receiving an onboarding request including permission data and an identification value from a first computing system, the identification value being associated with a first blockchain wallet for a blockchain associated with a blockchain network; generating a permission token based on the permission data and an alias, the permission token including verified identity data points; transmitting the generated alias to the first computing system in response to the onboarding request; receiving a token request from a second computing system, the token request including the alias; and transmitting the generated permission token identification value to the second computing system in response to the token request.
