MPC Security

Multi-party computation eliminates single points of failure. Your keys are never reconstructed in one place.

50+ Blockchains

Native support for Bitcoin, Ethereum, Solana, Cosmos, and 50+ networks, all under one API.

Real-time Events

Webhooks fire instantly on every state change, no polling, no delays, just live data.

No Counterparty Risk

Self-custody architecture means you retain full control. We never hold your private keys.
