Wallet Models

Secubit supports multiple wallet models to meet the diverse needs of institutional clients. These models define how private keys are managed, who holds control, and how approvals are enforced. By offering both custodial and non-custodial options, Secubit balances flexibility with bank-grade security.

In the custodial wallet model, Secubit’s HSMs hold the entire signing key, and clients delegate custody to Secubit’s infrastructure. Even so, user approvals are still required: transactions are only signed if the HSM verifies that the threshold of authorized users has approved the request. This provides the convenience of managed custody while ensuring that unilateral actions are not possible.

In the non-custodial wallet model, no single party holds the complete key. Instead, keys are divided into shares using Multi-Party Computing (MPC). One share remains inside the HSM, while the other share is distributed to client users. Transactions require both user approvals and collaboration between the HSM and user key share to produce a valid signature. This ensures that clients maintain direct control over their assets, while still benefiting from Secubit’s hardware-rooted enforcement and infrastructure.

Together, these models provide institutions with the choice of full custody convenience or elf-sovereign control, both backed by the same cryptographic protections and policy enforcement inside Secubit’s HSM network.
