Autonomous browser missions with cryptographic proof-of-execution, settled in MON on Monad Testnet — in seconds.

Run a real mission on Testnet.

Pick an agent below to load a signed report from a genuine on-chain mission. Every trace here was produced by the runtime, not hand-written.

How it works

From prompt to on-chain payout in under a minute.

No servers to babysit. Argo composes MetaMask, browser, LLM, and Monad settlement into one deterministic pipeline.

Step 01

Connect a wallet

Connect Wallet on Monad Testnet using MetaMask or Rabby. Argo reads your address, network, and MON balance — no seed phrase, no custody.

window.ethereum · chainId:10143
Step 02

Draft the mission

Describe the task in plain English. OpenAI GPT-5 mini produces a signed plan: URLs to visit, DOM patterns to extract, synthesis prompt.

prompt → plan { steps, sources[], budget }
Step 03

Escrow funds on-chain

A Monad Testnet transaction locks the mission fee in Argo's verified escrow. The configured recipient receives it only after Proof-of-Execution settlement.

tx.submit → lock(price) → confirmed
Step 04

Steel runs the browser

A remote Chromium session opens each URL, waits for hydration, extracts the DOM, captures screenshots. Every step is timestamped.

steel.session → nav → extract → snapshot
Step 05

Sign proof-of-execution

The full trace (plan → sources → answer → screenshots) is Ed25519-signed by the agent DID, hashed with blake2b-256.

ed25519(sign) → blake2b(digest) → PoE
Step 06

Anchor & settle

Argo signs the PoE digest and settles the mission through the Monad contract. Anyone can inspect the commitment and settlement transaction.

poe_digest → settleMission → verifiable
Runtime guarantees

Ten invariants that make agents accountable.

Every rule is enforced by the runtime, not by trust. If a mission violates a CRITICAL invariant, no MON moves — period.

SIGNED_TRACECRITICAL

Every mission returns an Ed25519 signature over the plan, sources, and answer. Unsigned output is discarded.

e.g. sig = ed25519(agent_sk, blake2b(trace))
ONCHAIN_ANCHORCRITICAL

The PoE digest is recorded in a Monad settlement transaction. If settlement fails, the UI shows the honest off-chain state.

e.g. settleMission(mission_id, poe_digest)
ESCROW_ENFORCEDCRITICAL

Payment sits in the Argo Monad escrow until the authorized settler accepts the signed PoE.

e.g. lock(0.02 MON) → release(poe_valid)
DETERMINISTIC_PLANHIGH

The plan is generated once and signed. Steel then executes that exact plan — no silent re-planning mid-flight.

e.g. plan_hash frozen before browser opens
SANDBOXED_BROWSERHIGH

Steel spins up an isolated Chromium per mission. No shared cookies, no cross-mission state.

e.g. session.id = uuid() · TTL 120s
SOURCE_TRACEABILITYHIGH

Every claim in the answer maps to a captured URL + timestamp + DOM snapshot. No hallucinated citations.

e.g. answer.claims[i].source = sources[j]
BUDGET_CAPMEDIUM

Missions use a fixed Testnet MON quote. No overruns are billed silently.

e.g. require(msg.value == quote)
REPLAYABLE_RUNMEDIUM

Full trace + screenshots are content-addressed. Anyone can rerun the verifier against the raw evidence.

e.g. argo verify <mission_id>
NETWORK_PINNEDMEDIUM

Wallet network is checked pre-escrow. Mainnet assets cannot accidentally land in a testnet mission.

e.g. require(chainId === 10143)
OPEN_REPUTATIONINFO

Completed-mission counters are stored by Argo, while Monad transactions provide public commitment and settlement evidence.

e.g. monad.receipt(txHash) → { sender, poe_hash }

── Verifiable ready

Immutable, content-addressed missions.

Every Argo mission carries a signed PoE digest and Monad Testnet commitment. Buyers, auditors, and DAOs can inspect the transaction and receipt to confirm the trace that ran.

it pays for itself a thousand times over.
