Claim 0:
1. A method for operating a self-custodial electronic wallet application associated with a user and executing on a user device, the method comprising:
receiving a request to execute a transaction with a decentralized finance service;
retrieving a public key and private key pair needed to execute the transaction, the private key further retrieved by:
accessing metadata associated with the user to determine: a
user-specified passphrase;
a user-specified sharding parameter previously specified by the user; 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;

using 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.
