Every governed AI agent action, verifiably attested.
Sentinel is the public transparency surface for Attestify OS — the governance layer for AI agents that touch money, access, or data. Every governed action: payments, access grants, data exports — attested on-chain via EAS and ACP-compatible contracts. No black boxes. Full auditability.
Sentinel isn’t a side project built for a token launch. Its budget, approval, and risk checks are the same governance engine Attestify OS runs across its wider product suite — re-exposed here as public, on-chain-attested endpoints for any agent, live first on Base and Robinhood for the agent ecosystem.
Not yet deployed. This box will show the real, verified $SENTRY contract address the moment it goes live — nowhere else.
This page and the official Orbofi page linked above are the only places the $SENTRY contract address is published. Any address from a DM, a reply, or another site is a scam — screenshots can be faked.
What Sentinel has caught
Every policy check is evaluated in real time — including the ones that fail. Overspending doesn’t reach the chain; it gets stopped here, first.
The $SENTRY token, in plain terms
Sentinel the product and $SENTRY the token are two separate layers. The product is governed and paid for independently of the token; the token exists to fund and coordinate the network around it — never to gate or control it.
What $SENTRY is — and isn’t
- Access perks — fee discounts, higher limits, and premium monitoring for holders. Live today — see the holding tiers below.
- Funding the network — treasury and ecosystem incentives that grow Sentinel over time.
- Bounded governance — network participation standards, risk-policy templates, service tiers, and ecosystem grants.
- Paying for Sentinel services — those are always billed in USDC via x402/ACP, never the token.
- Equity, profit share, or any ownership claim in Attestify OS the company.
- A vote on customer-specific approvals or emergency security actions — those stay off-token, always.
- A requirement to use the core product — Sentinel works whether or not you hold $SENTRY.
What holding actually saves you
This isn’t staking, and it isn’t locked. Holding $SENTRY at call time unlocks a tiered discount on the USDC price of every Sentinel check — Budget Gate, Settlement Verify, Fleet Drift Scan, Approval Workflow, Predictive Alert. The more agents you run, the more a holding pays for itself in avoided cost.
| Tier | Holding | Discount |
|---|---|---|
| Builder | 25,000 $SENTRY (0.0025% of supply) | 5% |
| Operator | 100,000 $SENTRY (0.01% of supply) | 10% |
| Scale | 500,000 $SENTRY (0.05% of supply) | 20% |
| Network | 2,000,000 $SENTRY (0.2% of supply) | 30% |
| Tier — scale | Monthly calls | Base cost | With holding |
|---|---|---|---|
| Builder — a few agents | 10,000 | $720 | $684 (save $36) |
| Operator — recurring checks | 100,000 | $7,200 | $6,480 (save $720) |
| Scale — ~100–300 agents | 1,000,000 | $72,000 | $57,600 (save $14,400) |
| Network — ~1,000+ agents | 10,000,000 | $720,000 | $504,000 (save $216,000) |
Base cost assumes an even split across all 5 Sentinel services at their published per-call prices ($0.05–$0.10) — a $0.072/call blended average. Your actual mix of calls will differ. Each row applies the discount tier realistically held at that scale (Builder through Network, per the ladder above), not a blanket top-tier assumption. Discount applies to real usage at current published pricing — not a return, not staking, not a promise of price appreciation. Total supply fixed at 1,000,000,000 $SENTRY on Robinhood Chain.
Where network growth goes
As real USDC fee revenue comes in from Sentinel usage, the intention is to use a share of it to buy $SENTRY back on the market — growth funding demand, directly. This is tied to actual fees generated, not guaranteed or scheduled in advance: if usage is low, there’s nothing to buy back with yet. If adoption goes the way we expect, this starts in the coming months. Not a promise, not a fixed schedule — a direct commitment to put growth back into the token as growth actually happens.
