Custody and wallet

Custody.

Self-custody with MPC threshold wallets. ERC-7579 modular validators enforce policy at signing time.

STATUS: Testnet
CRATE: tenzro-wallet
STABILITY: Stable
REFERENCE: ERC-7579

Threshold

Default 2-of-3 MPC shares. Auto-provisioned on identity registration. No seed phrase.

ERC-7579 modules

SOCIAL_RECOVERY_VALIDATOR  0x101d  N-of-M guardians
SESSION_KEY_VALIDATOR      0x101e  bounded session keys
SPENDING_LIMIT_VALIDATOR   0x101f  per-tx + daily ceiling

Composite signatures

Guardian quorum signatures combine Ed25519 + ML-DSA-65 (the PQ-hybrid composite). Every installed module must approve a UserOperation.

Defence in depth

On-chain validators are the primary control surface. The off-chain SpendingPolicyResolver is defence-in-depth, not the gating layer.
