Built on Cryptography,
Not Trust
Kairo Guard uses 2PC-MPC cryptography and on-chain policy enforcement to eliminate single points of failure—without requiring you to trust us.
The Problem with Traditional Wallets
For over a decade, crypto security has relied on a fundamentally flawed model.
$140B+ Lost Forever
Billions in crypto permanently inaccessible due to lost seed phrases, forgotten passwords, and misplaced recovery keys.
Single Point of Failure
Your seed phrase IS your wallet. Anyone who obtains those 12-24 words has complete, irrevocable access to all your funds.
Blind Signing
Most thefts happen because users can't read what they're signing. Malicious approvals drain wallets in seconds.
2PC-MPC: Keys That Never Exist
Two-Party Computation Multi-Party Computation splits your private key between you and a distributed network. The complete key is never reconstructed—not during generation, not during signing, not ever.
How It Works
- 1.Your device holds Key Share 1—generated locally, never leaves your device
- 2.Distributed network holds Key Share 2—spread across multiple independent nodes
- 3.Both shares required for every signature—neither can sign alone
- 4.Partial signatures combine mathematically without revealing shares
Why It's Secure
- ✓No seed phrase—nothing to lose, steal, or phish
- ✓Collusion resistant—compromising one party is useless
- ✓Continuous key rotation—old shares become cryptographically useless
- ✓Self-custody—you always maintain control, not us
From Request to Broadcast
Every transaction flows through policy validation and 2PC-MPC signing before reaching the blockchain—all in under 100ms.
On-Chain Policy Enforcement
Your security rules are stored on Sui and enforced before every signature. Not even Kairo can bypass your policies.
Daily, weekly, or per-transaction caps
Only send to approved addresses
Waiting periods for large transfers
Require additional signers for high-value
Distributed Network Architecture
The network key share is distributed across geographically dispersed nodes. No single server failure affects your access.
99.9% Uptime
Redundant nodes ensure the network is always available for signing operations.
Recovery Mechanisms
If Kairo ever goes offline permanently, recovery paths exist to restore your access.
10,000+ Sigs/Sec
Optimized 2PC protocols enable high-frequency operations without compromising security.
Recovery Without Seed Phrases
Lost your device? No problem. Kairo's recovery system uses identity verification and timelocks—not a piece of paper.
Designated Recovery Contacts
Pre-approve trusted contacts who can help initiate recovery. No single contact can recover alone—multi-party verification required.
- Family members, business partners
- Require 2-of-3 or 3-of-5 approval
- Contacts can't access funds—only initiate recovery
Timelocked Recovery
Recovery requests include mandatory waiting periods. If someone's trying to steal your account, you have time to cancel.
- Configurable delay (24h, 48h, 7 days)
- Notifications when recovery initiated
- Cancel button if you didn't request it

Security FAQ
What happens if Kairo goes offline?
The network is distributed across multiple independent nodes with geographic redundancy. If individual nodes fail, others continue operating. In the extreme case of Kairo ceasing operations entirely, recovery mechanisms exist to restore access to your funds through designated recovery contacts and timelocked processes.
Can Kairo access my funds?
No. Kairo holds one key share, but cannot sign transactions without your device's key share. Even if every Kairo employee colluded, they could not move your funds. This is mathematically enforced by the 2PC-MPC protocol.
What if my device is stolen?
A stolen device alone cannot access your funds—the network share is also required. You can initiate recovery from a new device using your pre-configured recovery contacts. The thief would need to compromise both your device AND the distributed network simultaneously.
Is 2PC-MPC new or unproven?
The underlying cryptographic primitives (two-party computation, threshold signatures) have been studied since the 1980s. The specific 2PC-MPC protocols used have been peer-reviewed, formally verified, and deployed in production by institutional custodians. We stand on decades of cryptographic research.
How is this different from multisig?
Multisig requires multiple complete private keys to exist. If any one key is compromised along with another, funds can be stolen. 2PC-MPC ensures no complete key ever exists. Additionally, multisig is chain-specific and visible on-chain, while 2PC-MPC works across all chains and produces standard single-signature transactions.
Can policies be changed without my consent?
No. Policies are stored on-chain (Sui) and can only be modified with a valid signature from your key share. Kairo cannot unilaterally change your policies. You can also add time delays to policy changes for additional security.
