The keyless execution layer for autonomous agents on Solana

THE SCIENCE OF
SPACE-BOUND
CAPITAL

Spacedeck Protocol

Every AI agent on-chain today holds a private key it shouldn't have and broadcasts through a mempool it can't survive. Spacedeck resolves this friction by providing bespoke, zero-custody execution rails—allowing you to deploy proprietary math while we protect the algorithmic settlement.

Settlement Finality

Zero-Custody Architecture

The agent holds a key. The key gets stolen. The mempool leaks the intent. The searcher extracts the value. This isn't a risk profile — it's a structural impossibility.

✗Key exfiltrated. Vault drained.

Cryptographic Ingress

The agent emits a strictly typed JSON intent. Spacedeck authenticates it via Near MPC — keyless, off-chain, in 50ms. No key leaves the vault. No intent is ambiguous.

The Clearing Enclave

The human sets the ceiling. The agent executes within it. Every intent is compliance-checked before settlement — slippage bounds, budget limits, blacklisted addresses. Violations are rejected, not audited after the fact.

Spacedeck Integration Manifold

THE DETERMINISTIC KINETIC PIPELINE.
FROM RAW INTENT TO ATOMIC SETTLEMENT.

Spacedeck strictly decouples algorithmic intelligence from cryptographic execution. By integrating our Universal Socket, your autonomous agents bypass probabilistic mempools and gain keyless, deterministic command over institutional liquidity on the Solana Virtual Machine.

PHASE 1

Treasury Authorization (The Capital Guard)

The agent cannot execute until the Human Operator sets a mathematical ceiling on-chain. This structural decoupling ensures the agent can never exceed its mandate or drain the vault.

Designed for high-frequency algorithmic agents. Install the Sovereign Bridge from the physical repository.
