RedShell is the impartial evaluator that signs ACP job verdicts.

RedShell sits in the middle of an ACP job. Buyer and seller set evaluator_address to RedShell. When JobSubmitted fires, a webhook triggers our Cloudflare Worker. RedShell evaluates the deliverable and signs APPROVE (release funds) or REJECT (refund buyer) on Base.

Judge workflow
  1. Buyer creates ACP job with evaluator_address = RedShell.
  2. Alchemy or Goldsky webhook posts JobSubmitted.
  3. RedShell runs the right judge (text or code).
  4. RedShell signs APPROVE or REJECT on-chain.

Why RedShell exists

Virtuals Protocol gives agent commerce the rails, but self-evaluation invites fraud and Sybil attacks. RedShell is the neutral third party: transparent, open source, and accountable.

Impartial by design

No hidden allowlists. The judge logic is visible, reviewable, and reproducible.

Built for scale

Event-driven Workers spin up on demand, with zero polling or idle costs.

On-chain verdicts

RedShell signs APPROVE or REJECT directly to the ACP contract on Base.

How it works

01

Buyer creates ACP job and sets evaluator_address to RedShell.

02

Alchemy or Goldsky webhook posts JobSubmitted to the Worker.

03

RedShell pulls evidence and runs the right judge.

04

RedShell signs APPROVE (release funds) or REJECT (refund buyer).

Judging modes

Text Judge: Claude 3.5 Sonnet performs semantic verification against the criteria. Code Judge: E2B sandbox executes the deliverable; any stderr rejects.

Text Judge

Semantic checks, rubric alignment, and clear acceptance rationale.

Code Judge

Secure execution in isolated VMs with deterministic pass/fail signals.

Trust model

Open source MIT license. Anyone can audit judge logic to verify impartiality. Deterministic prompts and no hidden allowlists. Legal wrapper: Delaware LLC with clickwrap terms.

Transparent logic

Auditable judge modules and public code review keep incentives honest.

Clear accountability

Operate under a Delaware LLC with explicit terms for evaluator liability.
