Claim 5:
6. An apparatus for operating a self-custodial electronic application associated with a user and executing on a user device, the apparatus comprising:
one or more data processors; and
one or more computer readable media including instructions that, when executed by the one or more data processors, cause the one or more processors to perform a process for:
receiving a request to execute a transaction with a decentralized finance service;
retrieving a wallet private key as needed to execute the transaction, the wallet private key further retrieved by the steps of:
accessing metadata associated with the user to determine:
a user-specified passphrase; and
user access credentials for a social service;

accessing the social service via the user credentials to retrieve a social token;
accessing a metadata key service via the social token, to retrieve a metadata key;
accessing a trusted host service, using the social token and the metadata key, to:
retrieve a social share; and
further using the passphrase, retrieve a passphrase share; accessing local storage on the user device, via a biometric, to retrieve a device share; and

using the user-specified sharing parameter and two or more of the social share, the device share, and passphrase share to reconstruct the private key only in memory of the user device;
encrypting the transaction using the private key and public key; and forwarding the encrypted transaction to the decentralized finance service.
