🦆 Quack AI Listed on Mantle Ecosystem
Quack AI is now on the Mantle ecosystem page, under AI & Data.
Right shelf. Most of that list helps an agent decide. We handle the part after the decision, which is the part that still quietly needs a human to fund gas.
On Mantle it doesn't. USDC and USDT0 settle from one signature, the sender never holds MNT, and every authorization stays auditable afterward.

🧾 Know When Not to Retry a Payment
An x402 seller can accept your payment and still fail to deliver
Most payment clients report that as a plain failure. Your agent reads failure, retries, and pays twice

💸 Closing the Work-Payment Gap
An agent pays an x402 endpoint. The endpoint takes the money and returns an error.
The money moved. The work did not.
Four ways the industry is trying to close that gap. Two of them already ship with Q402:

🧩 Q402 Escrow: What it looks like to use
Yesterday: Q402 Escrow went live on Base.
Today: what it actually looks like to use it.
One install, sign in with Google, and your agent creates and locks the escrow. The funds sit on-chain. Seller delivers, you approve the payout. Nothing arrives, the timeout sends it back.

🤝 Quack AI × @prom_io Collaboration
Quack AI × @prom_io 🤝
Same problem, two layers: agents transacting with counterparties they've never met, at machine speed.
Quack AI is the coordination and settlement backbone for the agent economy: an issuer-neutral layer where agents pay, get paid, and stay within the rules, across any stablecoin rail. Policy runs before authorization. Escrow replaces "pay first, hope second" with "lock first, release second."

🛡️ Escrow Payments on Base
x402 payments usually clear the moment the endpoint responds. Seller ships nothing, buyer chases.
On @base , the same payment can route into escrow. Funds lock on-chain. The owner approves release. Timeout refunds.
For unknown sellers, large tickets, or slow deliveries.
