Self-custody for crypto tokens is complicated and dangerous, which is why so many users outsource it to third parties, breaking crypto's promise of 'being your own bank.' Vault12 packages advanced cryptography into a simple user-interface for securing crypto tokens across an inner circle of trusted friends,colleagues and devices. This provides the security and recoverability of custodying with third-parties while preserving privacy and self-reliance.
