Enterprise Foundations

Engineered for security, compliance, and scale.

Every component designed to eliminate counterparty risk and simplify user experience.

MPC-CMP Key Security

2-of-3 threshold signature computation eliminates seed phrase liabilities. Key shares are encrypted and isolated across client devices and secure HSM enclaves.

✓ Zero single point of failure

ERC-4337 Smart Accounts

Delight Web2 users with gas sponsorship (Paymaster), batch transactions (multi-call), session keys, and automated biometric social recovery.

✓ Web2-grade user onboarding

Granular Policy Engine

Enforce corporate governance with multi-signature approval quorums, IP whitelists, transaction velocity limits, and automated Sumsub AML screening.

✓ Programmatic treasury control

40+ Omnichain Networks

Unified address structures across Ethereum, Polygon, Arbitrum, Solana, Bitcoin, Tron, and Base. Single integration for all Layer 1s and Layer 2s.

✓ Unified multi-chain balances

Frequently Asked Questions

We implement state-of-the-art MPC-CMP (Multi-Party Computation) with a 2-of-3 threshold signature scheme. The private key never exists in full at any point in time or on any single server. One key share is encrypted on your client device/app enclave, one sits in Coincashy HSM cloud enclaves, and one is held with an independent recovery agent.
