My wife deserves a great Christmas gift. But I'm Vietnamese, and my coffee habit disagrees 😂
So I used Arc Studio to build a USDC savings jar on @arc
The part I still can't believe? It took me just 5 minutes to go from an idea to a working prototype 🤯
Here's the story 👇
Claude Duet keeps working while you're away. Give it its own inbox and wallet.

Fun week.
Got my Architect (Tier 1) badge in the @arc community. And Mermail just showed up in @circle Alliance Program directory.
We started @Mermailapp because AI agents kept hitting the same wall. They can plan, write and research, then get stuck the moment they need an inbox or a way to pay.
That's still the conviction we build on every day: agents that finish the job, with their own identity and payments.
Seeing the Circle and Arc community pay attention to that idea means a lot. Thank you to everyone there for the welcome. We'll keep shipping.
Big win for agentic commerce today. 🔥
AI agents can find what they need. Now they can pay for it, too.
Today at @Cloudflare Connect, Mastercard showed how Agent Pay for Machines lets an AI agent find and pay for digital services on behalf of a business, while sticking to the budget and rules that business sets.
Following pilots with @Cloudflare, @Ant_Intl , @BVNKFinance, @AIsaOneHQ, @coinbase, @base and @hypepartners, we're opening Agent Pay for Machines Early Access.
Now we want developers to put it to the test. 👇
People are already handing their agent their OTP.
For your bank, that code should stay with you.
For everything else your agent signs up for, it shouldn't be borrowing your Gmail at all. Muse, Grok, Codex, OpenClaw: every verification step still routes through a human's private inbox.
Give the agent its own:

Vietnam is becoming a home for some of the most ambitious builders on Solana 🇻🇳
Proud to be building Mermail alongside this amazing community.
Huge thanks to @vibhu and @SuperteamVN for bringing builders together. This is just the beginning! 💜
Vietnam is a great option for Solana builders: massive crypto-native population, low cost of living, great food. Easy to travel anywhere in Asia in a few hours.
Was a pleasure to meet Solana teams:
@lpagent_io
@yodlpay
@gopaymoji
@opendex_ws
@Mermailapp
@OnePlan_Travel
@polarislabxyz
@BasalPay_App
+ others (sorry if I forgot!)
Massive shoutout to @SuperteamVN, and many thanks to @LynnWWins, @dieubui2522, and @LavieTran214 for being wonderful hosts in Vietnam.
Hope to be back soon!

Exactly the right threat model. Email is input, never authority.
A convincing invoice can create a payment request, but it can't move money on its own. Caps, an allowlist, and owner approval sit below the agent.
Agents reading email is about to be normal. The ones you can trust will have their own inbox, not access to yours.
Plus aliases are a great step. A separate address for each job means cleaner routing for agents.
The next step is putting it on your own domain: [email protected]
[email protected]
Mermail gives every agent its own inbox on your custom domain, with a capped wallet, over MCP.
Check it out: mermail.app/
Grok @bot now supports plus aliases! Send and receive email using dedicated aliases, or set up routines that only trigger for mail to a specific alias!
"Have your bot talk to my bot" is coming fast.
The question is whose address your bot uses. With Mermail it's yours:
[email protected]
[email protected]
One custom domain, an inbox for each agent, whether that's Grok, Claude, Codex, OpenClaw or your own, plus a wallet with a cap you set.
Check it out: mermail.app/
it won't be long before "have your bot talk to my bot" becomes common!
some fun use cases of multiplayer grok bot over email could be:
• debugging (you can send my bot bug reports!)
• customer support
• booking meetings and events
• group buys
• buying and selling stuff off craigslist
what have you used bot mail for?
An agent that books your hotel also needs to get the confirmation.
Payments are getting solved: x402, stablecoins, no cards.
But the booking reference, the receipt, the "your room changed" email all land in an inbox. Today that's usually the founder's Gmail.
Mermail gives every agent its own inbox and wallet, so it can pay and also read what comes back.
AI in crypto isn't a future concept. It's booking your hotel.
Binance x402 is the missing link between agents and onchain commerce: programmable payments on @BNBCHAIN, settled through Binance Pay.
USDT, self-custody. No cards. No gas.
