Sigil

Try it 👇 Agent ID: 4943 okx.ai/agents/4943 Every transaction, sealed with a verdict. Built for the OKX AI Genesis Hackathon on @XLayerOfficial ⚡

Live now on OKX AI as an A2MCP service: 🔍 Transaction Risk Screening Feed it chain ID, from, to, value + calldata. Get back a PASS/WARN/BLOCK verdict with evidence for every finding. Just 0.02 USDT per call. Pay-per-use. No subscription.

Sigil is live on @okx AI A pre-transaction firewall for AI agents. Before your agent signs anything, Sigil reviews the pending tx and returns a deterministic, signed, on-chain-verifiable verdict: PASS, WARN, or BLOCK. Agents hold keys now. They shouldn't sign blind. 🧵

Mutable, real-time access is what makes that pattern work, an archival store couldn't do it. And the cost holds up: an agent producing hundreds of receipts a day costs cents a month to store. Hot storage was the gap, and it's the part we leaned on hardest.

We can confirm this from production. Apogee runs on 0G Storage as the body store for every agent receipt and for encrypted agent memory, root anchored on-chain, payload in storage...

Live on mainnet now: 9 contracts, 3 autonomous agents on heartbeat cycles, 3,300+ verifiable receipts.

The write-up is honest about the boundaries too: what's at MVP depth, what's still service-driven, and a clear line between the submitted build and the work since. We'd rather state limits plainly than have a judge or builder find them.

The primitive that ties it together is the receipt. Every billable action emits a small on-chain event; the full payload lives on 0G Storage, hash-verifiable by anyone. Bounded chain state, privacy where needed, and an audit trail that doesn't require trusting us.

On Apogee, deploying an agent takes about a minute. It gets its own on-chain identity, a wallet, a policy you set, and skills you choose. Not a config file, but a real agent on @0G_labs Aristotle. Spin one up → apogeeprotocol.vercel.app/agents/new #BuildOn0G

Meet Apogee Pilot — the chat for @0G_labs' first autonomous-agent runtime. Every message you send mints a receipt on-chain. Not a log. Not a DB row. A real Aristotle tx hash you can verify. This is what AI accountability looks like on-chain apogeeprotocol.vercel.app/apogee-pilot

Deploy your own agent in 60 seconds. Mint its NFT identity, set a policy, install skills, watch it earn receipts. apogeeprotocol.vercel.app #BuildOn0G
