Quack AI

Building Q402. The first unified sign-to-pay execution and governance layer for the Agent Economy. Backed by @animocabrands @SkylandVC @KeneticCapital

[Quack AI @QuackAI_AI]

You're on the street. A deal's about to die. You need to send $200 right now.

Your wallet: "Insufficient gas. Buy ETH first."

Or you just tell your agent. Gasless. Settled in 0.8s.

This is Q402 ⬇️

[Quack AI @QuackAI_AI]

AI agents can already read, write, code, and coordinate. The missing primitive is payment.

Q402: stablecoins that move on intent, gas the agent never holds, policy the owner controls, and a Trust Receipt for every settlement.

The user defines the rules. The agent expresses intent. Q402 settles.

Blue is coming to Q402.

Same gasless agent payments.
Same EIP-7702 execution.
Same Trust Receipts.

A new rail is about to light up.

[Quack AI @QuackAI_AI]

@GracyBitget @cz_binance We removed the Bank Account and Crypto wallets as well.

I told my AI agent one sentence:
"Bridge 0.05 USDC from Arbitrum to Avalanche."

No bridge UI. No gas in my wallet.
~12 min later it landed, delivered by @chainlink CCIP.

And don't trust me. Every hop is public. Verify it yourself.

This is Q402. Agents move money across chains now.

[Quack AI @QuackAI_AI]

An AI agent shouldn't deploy a 500k-gas smart wallet just to send $3 of USDC.
▶️Smart-wallet powers for AI agents. Minus the smart wallet.

Q402 runs on EIP-7702: the agent's existing EOA signs in place, gas is sponsored,
and every spend is bounded by per-tx and daily caps you set.

Not enemies. 7702 even rides on 4337 infra. But for gasless stablecoin spend
from an agent's own wallet, 7702 is the lighter path.

10 EVM chains. USDC + USDT everywhere, 24 MCP tools in Claude, Codex, Cursor, Cline.

4337 vs 7702, side by side ↓

[Quack AI @QuackAI_AI]

AI agents shouldn’t pay every wallet they’re told to.

Introducing Q402 Reputation Gate.

Before settlement, Q402 verifies the recipient��s ERC-8004 agent identity and checks whether it meets your reputation threshold.

No match. No trust. No payment.

Programmable trust for agent payments. Live through Q402 Hooks in Claude, Codex, and MCP clients.

[Quack AI @QuackAI_AI]

An AI agent can decide what to pay. Q402 decides what it's allowed to.

Q402 Hooks 1.0 - Live on @BNBCHAIN.
Set spend caps, recipient allowlists, time windows, approval holds, reputation + compliance gates. Every payment is checked before funds move.

Autonomous, and governed.

@BNBChainDevs Good to see the payment layer getting real attention in this thread.

We've been running gasless agent payments on BNB Chain with Q402, so agents pay in stablecoins without touching native gas.

[Quack AI @QuackAI_AI]

[Quack AI @QuackAI_AI]

Q402 is now live on @arbitrum.

Your AI agent just stopped asking for gas money, on the largest Ethereum L2.
Sign once, settle in USDC or USDT, no ETH required.

npm install @quackai/q402-mcp.

Plug it into Claude, Cursor, Cline, Codex, or any MCP client, and your agent gets gasless payments, recurring payments, and Agentic Wallets out of the box.

Last clinic, last chance. Don't sit on the question you've been overthinking.

Our APAC Lead @phavorable is on today's @Mantle_Official fireside with @MerchantMoe_xyz and @AlloraNetwork.

If you're building agents for The Turing Test Hackathon, come ask us anything: payments, autonomy, governance, whatever's blocking you.

See you there✈️

[Mantle @Mantle_Official]

You had three Mentor Clinics to bring your questions, blockers, and ideas you've been overthinking.

But the fourth is where it ends, and it's your last chance to ask anything you need for The Turing Test Hackathon.

We'll stay on to answer as many questions as we can ↓

[Quack AI @QuackAI_AI]

Uniswap v4 brought programmable hooks to DEX liquidity.

We’re bringing programmable policy to AI agent payments.

Q402 Hooks adds compliance checks, spending rules, reputation gates, oracle conditions, and multi-payee splits before settlement.

Payments shouldn’t just move. They should understand the rules.

Available in Claude, Codex, and other MCP clients this Thursday.
Install: npx -y @quackai/q402-mcp

Quack AI ships 24/7. Apparently, sleep isn’t in the roadmap.

[Quack AI @QuackAI_AI]

Q402 by the numbers:

60,000+ gasless stablecoin payments settled
10,000+ MCP downloads across 10 EVM chains

Agents aren't just installing Q402, they're paying with it.
Every transaction carries a signed, verifiable Trust Receipt.

Every gas fee sponsored.

Q402 Agent Wallet now supports public agent registration.

With one signature, builders can mint an agent NFT on BNB Chain and link the agent wallet as the Q402 payment endpoint in metadata.

From there, reputation starts building through real Q402 usage.

More transactions → more activity data → more reputation.

Viewable on 8004scan.
Your AI agent is now trackable on-chain.

Turing Test Hackathon builders!
Your AI agent shouldn't be asking for gas money.
Q402 makes stablecoin payments invisible on Mantle.

Sign once, settle in USDT, no $MNT required.
One less thing to build.
