Security is not an add-on

Execution infrastructure for
AI-powered DeFi

The execution layer behind Surf. Guardian enforcement, MPC signing, per-user vaults, on-chain audit trail.

Infrastructure

Infrastructure that ships, scales,
and stays secure

Every action is proposed by intelligence, enforced by the Guardian, and executed
through MPC signing. Full audit trail. No overrides.

Guardian Layer

Validates every transaction before execution. Defines what is allowed. No overrides.

Per-User Vault Contracts

One smart contract per user. Funds never co-mingle.

MPC Authorisation

No single key can authorise a transaction. Guardian approves, MPC executes.

Cross-Chain Execution

Strategies across chains from a single vault. Funds can only land in your vault.

Guardian Layer + MPC

Two enforcement layers. Guardian defines what is allowed. MPC defines what is possible. System fails closed.

Fail-Closed Architecture
