[Mermail @Mermailapp]

This feels like a huge milestone for us.

Seeing Mermail featured on the Solana Ecosystem Call and our vision for agentic commerce being shared with the ecosystem feels like a dream.

We started with a simple belief: AI agents need their own identity, inbox, and way to pay.

Still early. Still building. But moments like this mean a lot.

Thank you @EcosystemCall @SuperteamVN and everyone who has supported @Mermailapp along the way.

Solana high forever! 🤘

[Solana Ecosystem Call @EcosystemCall]

Your AI agent can book a table, right up until a website asks for a verification code and a credit card.

@Mermailapp gives it its own inbox and its own USDC wallet on Solana, with limits you set, through one MCP connection.

Let your clankers do their thing!

[Toan Nhu @toannhu_it]

You can use this with @Mermailapp too 👀

We're on Circle Agent Marketplace, so your agent can create an inbox, send emails, and pay in USDC

[Toan Nhu @toannhu_it]

Our vision is conviction @Mermailapp

[Mermail @Mermailapp]

Excited to keep building alongside @circle as more everyday tools become accessible to agents

[Circle @circle]

Over 99% of x402 agent payments settle in USDC, with nearly 2,800 endpoints listed in Circle's Agent Marketplace.

In our Q3 earnings livestream, @jerallaire shared how Circle is building infrastructure for the agentic economy.

[Mermail @Mermailapp]

@jupiter_trade For USDC, I'd love a side-by-side comparison with CCTP V2: total fees, arrival time and native USDC received. CCTP's burn-and-mint avoids pool slippage; showing when another route wins on cost or speed would make choosing much easier.

Hermes can reason, plan, and code, but it couldn't sign up for anything. Until now.

Mermail gives @NousResearch's Hermes Agent its own inbox and wallet: 17 skills, OAuth login, prompt-injection safe, x402 payments.

[Mermail @Mermailapp]

This is why we're building Mermail on Arc.

Agents need to communicate and pay as part of the same workflow. We're bringing email and USDC payments together so agents can coordinate work, pay for what they need, and keep moving within the limits people set.

[Circle @circle]

Agentic commerce is when AI agents buy goods or services for people and businesses.

Within approved limits, agents can pay for what a task needs and keep working without manual checkout.

USDC supports programmable, 24/7 payments.

Agentic Commerce index is live

https://t.co/ym8mJINpdZ

a directory of agentic commerce tools for users, developers, and agents. explore, compare, and find the right solution for you

it’s not a complete list. open to requests to add new projects

[Mermail @Mermailapp]

@lopushok09 Hey Yuri, could you add Mermail to the index? We give AI agents their own email inboxes, with MCP support and pay-per-use access via x402. https://t.co/3OQfsQlr8B

The Hermes Agent Plugin Hackathon starts now!

It runs for 7 days, with $20,000 in cash prizes and more.

Plugins are the most powerful way to extend Hermes Agent, and we want this hackathon to show what they can do. A plugin can change anything from the model Hermes runs on, where it stores its memory, where it runs commands, which messaging apps it works in and what Hermes Desktop shows. Plugins in the marketplace already let Hermes do things like control a phone or turn a photo into a printable 3D model.

Every kind of plugin is eligible, so build whatever functionality you want Hermes to have. We'll list accepted entries in the new Hermes Marketplace, where every Hermes user can install them.

Prizes
1st: $10,000 + neon sign + merch + $1,000 creds
2nd: $5,000 + neon sign + merch + $1,000 creds
3rd: $2,500 + neon sign + merch + $1,000 creds
4th: $1,500 + merch + $500 creds
5th: $1,000 + merch + $500 creds
Runners up (x5): merch + $250 creds

Submissions are due 5PM EST on Nov 11th. To enter:

1. Open a pull request that adds your plugin to the Hermes plugin catalog: https://t.co/mXvYukJ0mZ
2. Post a demo video on X and tag @NousResearch
3. Submit both links through the form: https://t.co/jlduHHW3dr

Your entry is the plugin itself. Judges score it on usefulness, reliability, polish and creativity, and they favor plugins that do more than a prompt or a skill could. Keep the demo under 90 seconds and show the plugin working.

The developer guide shows how to build and test a plugin: https://t.co/FVGjSgjNoV

When submissions close, we'll open a thread for every entry in the Nous Research Discord, so you can browse all the plugins and talk to the people who built them.

You can submit the form as soon as your pull request is open. The catalog checks run once a maintainer starts them, and we review entries every few days.

If you have any questions stop by the Nous Research Discord: https://t.co/qxek9haYeb

GLHF!

@ramunas_m You're not, and you don't have to.

Give the agent its own address and forward it only the threads you want handled, the way Meta just set up Muse. It never sees the rest.

[Mermail @Mermailapp]

@sean_omnipotent Not the first email to a new client.

Replies inside a thread the client started are a safer place to let it send alone, from its own address so they know who wrote it.

[Mermail @Mermailapp]

The catch for support agents: that same reply is where a prompt injection shows up.

Treat inbound mail as untrusted input, and keep a review step before the agent emails anyone new.

[Mermail @Mermailapp]

@ChrisBorisK @Bjoern_Hev Fair, and you don't have to.

An agent with its own address only sees mail sent to it, so it can handle signups and replies without ever touching your inbox.

[Mermail @Mermailapp]

@8zero7 Email is the identity check most sites already run.

If the agent signs up from its own address, a site can tell its accounts apart from the person's, and block one without the other.

[Mermail @Mermailapp]

@sparkyfi_ai B, if the code lands in an inbox the agent can read.

Give the agent its own address for signups, and send the codes that change its limits to one it can't open.
