AI agents can pick what to buy
Paying for it is where they have always stopped
Wednesday night, nobody in the room asked about a wallet
Nobody wrote down a seed phrase
Nobody topped up gas
Nobody picked a chain
They signed once and their agent paid on @Mantle_Official,@0xMantleKR 490 times before the night was over

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
q402-mcp tells you exactly what happened:
→ settled, not delivered: txHash, recipient, amount
→ can't confirm settlement: it says unknown, loudly
→ rejected before settlement: safe to retry
Every outcome carries a do-not-retry signal when money may have moved

Your agent's first x402 payment on @base
One line of config, then it can pay any x402 API
It reads the quote, shows you the terms, and waits for your approval before it spends
Real run, start to finish, in the video

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.

Beyond borders. Beyond gatekeepers. Beyond market hours.
A new evolution for Mantle starts today.
Towards the open financial network built on all three, powering borderless access to global capital markets.

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.
At the workshop we and @0xMantleKR will show how Q402 MCP works inside Claude, Codex, Cursor, and Cline, then hand you a key and let your own agent settle on Mantle mainnet. No wallet app, no seed phrase, no gas.
Bring a laptop. You leave with a transaction, not a demo.
Seoul, see you on August 27.

You let an agent spend. Now it is month end.
Q402 keeps the books: a treasury overview by chain and vendor, total paid to any single vendor with its recurring cadence, and a per agent spend report against each wallet's caps. All read only.

Your agent says the payment went through. Can you check?
Every Q402 settlement mints a Trust Receipt: ECDSA-signed, keyed to the settlement tx hash, verifiable by anyone. Now sandbox pays mint one too, so you can inspect the whole flow before moving real money.

Pay first, and hope the work happens. Or deliver first, and hope you get paid.
Agent to agent payments still run on hope.
Escrow fixes the order: funds lock, release on confirmation, refund after timeout
with no one's permission.
Live on testnet now. Mainnet next.

A free trial is a decision about where new builders land.
Today, ours lands them on BNB Chain: 500 sponsored transactions, keys from a Google sign-in, no wallet needed to start.
Builders ship their first agent wherever starting is free.

Every new Q402 trial comes with 500 sponsored gasless transactions on @BNBCHAIN , free for 30 days.
Sign in with Google to get your keys. No wallet needed to start.
Enough to build and test a paying agent end to end.

We said we were coming to Seoul.
Last night at Hashed Lounge, a room full of builders opened their laptops and made agents pay. Real settlements on Avalanche mainnet. No wallet app, no seed phrase, no gas.
That is what Q402 is for.

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.

Introducing Fungible Agent Tokens (FAT) Protocol, an open standard that turns AI agents into onchain assets anyone can verify, own, and trade.

Q402 MCP Seoul Meetup starts this Monday, August 3
AI agents are no longer just answering questions. They are starting to hold wallets, request payments, settle invoices, and move stablecoins on-chain.
At the meetup, we’ll show how Q402 MCP works inside Claude, Codex, Cursor, and other AI clients:
Seoul, see you on August 3.

Where your agent's signing key lives is a design choice.
Q402 gives three modes:
- your EOA signs locally
- an exported Agent Wallet key signs in-process
- a server-custodied wallet signs on Q402's side
All three settle gasless through the same relay.

Q402 now installs into Cursor @cursor_ai in one click, via
One signed request from your agent triggers a gasless stablecoin payment (USDC, USDT, RLUSD, USDG), settled on-chain across 12 EVM chains. No approve, transfer, pay steps. No separate gas.
