Deploy yourAI trader.
An autonomous agent that manages USDC on Arc. It watches the market, decides each move, signs it with a Circle wallet, and records the proof on-chain. Every decision is yours to read and verify.
- Circle Wallets
- USDC on Arc
- ERC-8004 identity
- On-chain proof
Sample cycle
What we aim for when a trade goes through.
One decision, end to end. The setup, the call, the trade, the proof on Arc. Numbers shown are illustrative. The structure is the point.
Hypothetical example. Past performance is not indicative of future results.
From a quiet scan, to a permanent record.
Most ticks do nothing. That is the point. When the agent finds a setup worth taking, the whole loop runs in seconds and the proof ends up on-chain forever.
Watches the markets
Selbo polls the perps it cares about on a cadence it picks for itself, anywhere from a couple of minutes to half an hour. Mark prices, funding, open interest, recent candles, where price sits relative to value. Most ticks find nothing worth doing and it logs them as such.
Reads the setup
When something looks real, Selbo reads the structure: value area, regime, recent candle shape, and lessons extracted from its own past closed trades. No hardcoded playbook, no preset rules. The agent forms its own thesis from what it sees.
Takes the decision
One LLM call writes the entire move. Direction, size, leverage, stop, target, the plain-English reasoning, and how confident it is. The agent can also decide to do nothing - and most of the time that is exactly what it does.
Acts on it
If it decides to trade, the order simulates against the live Hyperliquid testnet mark price. Paper mode for now, no real capital at risk. But the action and the Circle wallet that signs it are both real on-chain.
Records the proof on-chain
The decision plus a hash of the full reasoning is anchored on Arc from your Circle wallet, on a source-verified contract anyone can read. Open the transaction on Arcscan and the agent's own words are bound to the on-chain record. It cannot revise what it did after the fact.
Every move, on the record.
Every Selbo decision lands on Arc as a permanent on-chain event. The contract that records it is source-verified - click through and read the Solidity. Field values below are illustrative; the contract address is real.

Things you should ask before deploying.
01Is this real money?
Not yet. Selbo runs on Hyperliquid testnet with simulated capital, quoting against real mainnet mark prices and funding so the numbers stay honest. No actual capital is at risk. A live-money toggle lands after the trial, and only for accounts that opt in.
02What happens when it loses?
Nothing dramatic. A losing decision is recorded the same way as a winning one. The reasoning goes on Arc, and the agent extracts a one-sentence lesson from what went wrong and feeds it into the next decision. Selbo is allowed to be wrong - the useful signal is in what it learns from being wrong.
03Can I stop it at any time?
Yes. There is a kill switch on your dashboard. Flip it and your Selbo stops cycling. The wallet stays attached to your account on the testnet and stops trading the moment you flip the switch. You can come back later or never.
04How is this different from a copy-trading bot?
A copy-trading bot mirrors someone else without reading. Selbo writes its own thesis from the market structure, picks side and size and stop and target on its own, and anchors the reasoning on Arc so you can read exactly why before deciding to trust it. You are reading an autonomous decision, not following anyone blindly.
05Where does my reasoning go?
Every decision gets recorded on Arc Testnet as an on-chain event with the reasoning hash, the verdict, and the Circle wallet that signed it. The full plain-English thinking lives in your dashboard. If you opt in, your Selbo also has a public page anyone can read.
06What does it cost?
Free during the trial. Wallet, simulated capital, every decision, all free. A paid tier comes later for users who want higher cadence, multi-asset coverage, or the personal-agent flow. You will not be charged anything you did not explicitly sign up for.
