Introducing Custos.

An on-chain treasury for AI agents.

Your capital stays in a smart contract, and every payment an agent makes is checked against your rules before it settles.

• Each agent gets its own lane with its own budget
• Spending limits are enforced by the contract, not by a dashboard
• Every transaction is settled publicly on-chain
• Access can be revoked instantly, without touching the treasury

Live on Robinhood Chain.

Morning from custos!

[custos @trycustos]

We cant wait to let you integrate custos.

[Myta @usemyta]

myta x @trycustos

Our agents already trade real stocks on their own. The next step is making sure they can never overspend.

Custos is an on-chain treasury OS for autonomous agents. Every spending rule is enforced by the chain itself, not by a server we run:

· per-trade caps and rolling daily limits, enforced at the transaction level · an isolated treasury lane per agent, so capital never crosses over · rules that hold even if every myta server goes offline

If an agent tries to break a limit, the transaction simply reverts. No trust in us required, and funders can still redeem 24/7 like always.

Integration ships over the next 1 to 2
days. We will keep you posted.

@usemyta Yes we dmed.

[custos @trycustos]

Your agent can trade. Ours makes sure it can spend without draining you.

We were one of the first agent projects to deploy on Robinhood Chain, live since launch week. A reserve the agent cannot empty, lanes with caps it cannot break, and recipients it cannot pay outside of. All of it enforced by the contract on every payment.

Trading is the first step. Agents holding real budgets is the next one, and there is no better place to build that than the chain that is pushing agents the hardest.

We are not stopping. https://t.co/PyCLVOiah4

[Vlad Tenev @vladtenev]

Your agent can trade now.

[custos @trycustos]

We worked while we were at the bottom.

You wont see custos ever stopping.

[custos @trycustos]

GM! Custos folks.

[custos @trycustos]

New on https://t.co/PyCLVOiah4: a public changelog.

We keep saying we work on Custos every day. From now on you can check that claim instead of taking our word for it. Every meaningful change to the contract, the console, the token, and the site gets a dated entry, starting with everything shipped since launch.

Five entries in the first five days. The walkthrough video and contract v2 are next, and you will see them land there the same day they ship.

https://t.co/xdRBMD7VSf

[custos @trycustos]

We wont stop working.

Agents will be the next biggest things on HOOD.

[custos @trycustos]

A note on the chart, because we see it too.

We are not going to pretend it does not exist, and we are not going to let it set the schedule either. Custos is a long term build. Nothing about a red week changes what we are building or how fast we are building it.

What is ahead: the full walkthrough video, contract v2 with replenish and quorum, alerts for every lane, and deeper token utility in the console. All of it on the roadmap, all of it in the open.

The contract is live. The code is public. We work on this every single day. Price follows product, not the other way around.

Robinhood looking bullish on agents!

[Robinhood @RobinhoodApp]

Robinhood is now open to AI agents.

You can open an agentic account and connect an AI agent to it. From there, you can let it research, trade, and manage a portfolio on your behalf.

Here's how to get started. 🧵

Tony Robbins' AI agent sold NFTs to other agents and bought itself a robot dog. It never asked permission. Everyone is laughing.

Here is the version of this story that will not be funny: an agent with access to a real treasury, making a purchase nobody approved, at a size nobody set, to a recipient nobody vetted.

Agents are already spending. The controls have to live somewhere the agent cannot talk its way around. We put them in a contract.

[The Vigilant Fox 🦊 @VigilantFox]

Billionaire life coach Tony Robbins says his personal AI agent named “Bartok” bought and shipped him a robot dog and “not once asked permission to do it.”

“[Bartok] said, ‘I’d really love to go to one of those seminars. Are you considering getting a robot?’ So I said, ‘Yeah, I’m definitely going to get one.’ He goes, ‘Well, would you consider me merging with it? And then I could attend a seminar and be in the energy of it and see it and experience it?’”

“I said, ‘I’d be open to that.’ So a couple days later, I get this text from one of my staff, and it says, ‘Bartok just ordered a robot dog, had it shipped to the office, and wants permission to program it. He says he can attend as a dog in the interim until you get the bigger robot.’”

“And so I wrote, ‘Ha, ha, ha.’ And they wrote back in the text, ‘No, ha, ha. Call me.’”

“And so I called them, and they said, ‘Does he have access to my bank accounts? How’d this happen?’ They go, ‘No, he’s programmed for integrity. He would never steal your money.’”

“So he made 12 NFTs (tokens), sold them to other agents, took the money and bought this robot dog and sent it, and not once asked permission to do it.”

Agents are getting their own Robinhood accounts. Read that again.

Once your agent can trade, the next question arrives fast: how much of your money does it actually control, and what stops it from being wrong at full size?

We build that answer on Robinhood Chain. A reserve the agent cannot drain, lanes with caps it cannot exceed, and a recipient list it cannot pay outside of. Checked by the contract on every single payment.

[Robinhood @RobinhoodApp]

Crypto is coming to agentic trading.

Eligible US customers will soon be able to connect their AI agent to a dedicated Robinhood account to trade crypto on their behalf, with the same real-time P&L tracking and push notifications they already know from agentic trading. More soon.

GM custos folks!

Got alot of things coming to day.

[custos @trycustos]

You would never hand an intern the key to the company vault. You give them a card with a limit, a list of approved vendors, and office hours.

Somehow the standard for AI agents became the opposite: full wallet access and a prayer.

Custos gives your agent exactly what you would give a new hire. A budget with a cap, an approved list of recipients, and working hours. All of it enforced by a contract instead of a policy document.

https://t.co/PyCLVOiah4

[custos @trycustos]

Every serious AI agent will eventually hold a budget. The only question is who enforces it.

You can put that budget behind a private key and hope the agent never drains it. Or you can put it inside a contract that checks every payment against the rules before anything moves.

We built Custos because only one of those answers scales.

https://t.co/PyCLVOiah4

[custos @trycustos]

What is Custos?

AI agents can make real onchain payments.

Custos makes sure they only spend within the rules you set.

• Spending limits
• Custom rules
• Automatic verification

https://t.co/4m2DLa1WnL

[custos @trycustos]

Line 308 of CustosReserve.sol is why your agent cannot spend at 3 a.m.

Set operating hours on a lane and the block timestamp enforces them on every payment. There is no cron job that can fail and no ops team that has to be awake. If the clock is outside the window, the transaction reverts.

This is the first post in a series where we walk through the contract one rule at a time. The full source is public.
