🧠 FAT Brings an Economic Body to AI Agents

FAT gives AI agents an economic body. Governance gives them a nervous system.

@MossAI_Official's Fungible Agent Token standard is the missing interface for tokenizing autonomous agent economies — and maps cleanly to how AI-governed DAOs already operate.

Excited for what ships next.

August 27
Q402 Builder Workshop with @Mantle_Official

AI agents are no longer just answering questions. They hold wallets, request payments, settle invoices, and move stablecoins on-chain. The part that was still missing is the rail underneath.

🦆 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
