Abstract
Methods, systems, and devices for token management are described. A custodial token platform may communicate with a wallet application to support a multi-party computation wallet and transfer of private keys and key shards to support wallet cloning and key export. The custodial token platform may receive a message signed by a first key shard, sign the message using a second key shard, and broadcast the signed message to transfer a token between the wallet application and a recipient address. The custodial token platform may receive an encrypted payload including the first key shard, and transmit the encrypted payload to a second client application for decryption by the second client application on a second user device. Additionally, the wallet application may support export of the private key based one or multiple authentication techniques, which may cause retrieval of the key shards and display of an indication of the private key.
