01 / THE PROBLEM

AGENTS HAVE EYES.
THEY DON'T HAVE BRAKES.

Autonomous AI agents hold raw private keys with total authority. One hallucination, one prompt injection, or one bad strategy can drain a wallet in a single block.

OnlyFence provides the invisible boundary. No backend. No cloud. No middleman. Just a local, hardened policy engine that ensures your agent only does what you've authorized.

02 / CORE LOGIC

THE POLICY PIPELINE.

EDITABLE_POLICIES

The Engine

Define spending limits, volume caps, and token allowlists in a simple TOML config. Composable safety checks that adapt to your strategy in real-time.

# ~/.onlyfence/config.toml
max_single_trade = "$200 USD"
volume_cap_24h   = "$500 USD"
allowed_tokens   = ["SUI", "USDC", "USDT"]
ENCRYPTED_SIGNING

The Vault

BIP-39 mnemonic generation and local-only keystores. Your keys never leave your machine.

✓ Keystore encrypted locally
✓ BIP-39 mnemonic secured
REALTIME_SIMULATION

The Oracle

Every trade is simulated via RPC and priced via Oracle before execution. Zero surprises at signing time.

> Simulating via RPC...
> Oracle price: $1.24 USD
MACHINE_READABLE

The Agent API

Direct JSON output for seamless integration with Claude, Cursor, and custom agent scripts.

03 / THE ADVANTAGE

WHY THIS SYSTEM?

[ƛ]

ZERO LATENCY

Policy evaluation happens in-process. No API round-trips to slow down your strategy. Sub-millisecond decisions, every trade.

[Ø]

ZERO INFRASTRUCTURE

No servers, no accounts, no tracking. Privacy is the default, not a feature. One install, full enterprise-grade guardrail power.

[◉]

AUDIT-READY

Every decision—approved or blocked—is logged to a local SQLite database. Complete forensic trail for every agent action.

[↯]

DEVELOPER FIRST
