Abstract: Methods, systems, and devices for data management are described. A custodial token platform may receive a request, from a client application on a user device, to generate an attestation record associated with a user profile of the custodial token platform. The custodial token platform may verify, after receiving the request, that the user profile is associated with the set of attributes for the requested attestation record. The custodial token platform may broadcast, after verifying that the user profile is associated with the set of attributes, a first message configured to generate the attestation record via a blockchain network, where the first message is signed using a key associated with the custodial token platform. The custodial token platform may broadcast a second message configured to store a mapping of an identifier for the attestation record and a self-custody blockchain address associated with the user profile.

Abstract: Methods, systems, and devices for data management are described. A custodial token platform implements a preminting process to facilitate wrapping staked crypto tokens and enables unwrapping the wrapped crypto tokens for liquid staking crypto tokens. The platform receives a first request to wrap a first amount of a first crypto token that is staked. The platform associates a second amount of the second crypto token with the first user profile, where the second crypto token is transferrable and minted, and based on a first value of a current conversion ratio between the first crypto token and the second crypto token. The platform receives, from a first or second user profile, a second request to unwrap the second crypto token, which is based on a second value of the current conversion ratio between the first crypto token and the second crypto token.
