@BenjaminHe26093 Right, it's the only path with an actual contract.
rejected_policy / amount_over_cap is something the UI can render, and CI can assert against. "Something went wrong" is neither.

If an LLM can invent a swap, it can invent a bad one.

That’s the problem.

Most crypto “AI agent” demos stop at a chat box. IntentGuard starts where those demos get dangerous: the money path.

I shipped a public Flutter × Go vertical slice where natural-language DeFi intents cannot skip the gate:

NL intent
→ untrusted planner (mock or LLM)
→ JSON Schema (legal shape)
→ policy engine (allowed money)
→ per-step human Approve
→ ABI-encode stored step JSON → Anvil tx_hash

…or a hard reject with a code + message.

No unsupervised txs. No raw model hex on the wire.

What this solves:
• Untrusted AI output on money-adjacent flows
• Prompt-only “limits” that aren’t enforceable
• Client-side checks you can walk around
• Chat demos that hide the reject path

Deep cut:
schema → is this a legal plan?
policy → is this amount / recipient / spender allowed?
human → should this step run now?
executor → only structured steps that already passed

Demo fixture that matters:
swap 150 USDC → rejected_policy / amount_over_cap

Happy path still requires sequential Approve → succeeded steps → copyable Anvil hashes.
History splits Completed vs Rejected from backend status.

Stack:
Flutter (Bloc, Dio, go_router, secure JWT)
× Go API (Postgres, planner interface, policy codes)
× Foundry mocks on Anvil
× Docker Compose
× CI evals

Local architecture demo — not mainnet, not custody, not an autonomous agent loop.
The product is the control plane.

I build production Flutter for crypto/fintech wallets. IntentGuard is open proof of how I’d put an AI planner on a money path without pretending the model is the control plane.

I’m a full-stack engineer with 7+ years of experience — Flutter, fintech/Web3, and integrating AI into real product workflows (not just demos).

Open to senior full-stack/mobile / AI-enabled product roles (remote EU-friendly).

⚠️ Connecting an AI agent to a tool is easy. Deciding what that tool is allowed to do is the real work.

Most teams treat MCP like a plugin folder: install → connect → ship.

Wrong mental model.

🔐 MCP is an authorization surface.

Before I trust a tool call:

1️⃣ Who is acting?

2️⃣ What’s the smallest scope?

3️⃣ What’s the blast radius? (read / reversible/irreversible)

4️⃣ When does policy block it?

5️⃣ What gets logged after?

💡 Capability is useful. Bounded capability is what makes it shippable.

Which question do you ask first when adding a new MCP server?

AI product engineers aren’t paid to pick the model.
You’re paid to design what happens after it speaks.
2026 stack:

Model proposes
→ Schema (legal shape)
→ Policy (allowed side effects)
→ Human Approve (irreversible steps)
→ Executor runs stored structured output
Not prompt engineering.

System design for a teammate with no badge access.
Gate by action risk, not model confidence.

Fail closed with codes — not “sorry.”
Evals in CI or you don’t have a product.

Public slice (Flutter × Go): IntentGuard
NL intent → schema → policy → Approve → Anvil

@Hiraweb3 😂 “Training wheels” is a great way to put it. The goal is AI that can help without being trusted with your funds.

We keep pointing out where Dart is lacking, but I don't see enough people talking about where Dart nailed it.

Vandad is one of the most valuable persons in the flutter community.

With his deep knowledge of #Flutter and Dart, you can learn a lot.

Thanks Vandad, for your upcoming new free course. It can help a lot.

[Vandad Nahavandipoor @vandadnp]

I'm considering putting my #free #Flutter #course on #Coursera (for free of course as well) so those of you interested in gaining an #official #certificated can do that. Would you be interested in that? 🤙🏻 Will be available at end of Jan 2022.

[Omid Mirzaei | Full-stack × Crypto × AI @OmidTheTechGuy]

Great article 👌
Recommend to all #Flutter developers.
