Infinex vs Senpi: a passkey account that trades like a CEX, or an AI agent that runs your Hyperliquid perps
Infinex and Senpi both trade Hyperliquid perps from a self-custodial account you open without a wallet, and that is where the overlap ends. Infinex is an onchain account with a passkey instead of a seed phrase: fund it with any token on 25 networks, then trade perps on Hyperliquid and Lighter from a CEX-style terminal with 60% of the builder fee paid back on every Hyperliquid trade. Senpi is an AI trading agent: you describe a strategy in a sentence and the agent writes it, runs it 24/7 under a risk harness, protects every strategy built from a rule or a template with DSL, and reads wallets with a proven record for you, from the app, from Claude or ChatGPT, or from the Chrome Companion.
The honest split: Senpi wins where you want the strategy built, run and protected for you; Infinex wins where you want the smoothest manual account onchain, two perp venues and cashback on the fee. Facts below come from infinex.xyz, its Pro page, support centre and Terms of Use (Nov 25, 2025), DefiLlama’s on-chain record of its Hyperliquid builder fees, senpi.ai/pricing and senpi.ai/fees, as of Nov 7, 2026.
TL;DR

| Building and running a strategy | Manual perps on 100+ markets to 40x: drag TP/SL on the chart, reverse a position, close everything; nothing runs for you | Describe the thesis in a sentence; the agent writes the rules, shows them to you, then runs them 24/7 on a hosted runtime under a deterministic risk harness; edits apply live | Senpi |

| Following traders | None documented | Mirror a trader you choose, after the agent researches their record on whole-book profit, margin, drawdown, timing and fee load, sized 0.1x to 4x, with an exit attached | Senpi |
| Custody | Self-custodial account secured by a passkey; no wallet connection and no seed phrase | Non-custodial embedded wallets with exportable keys; each strategy trades from its own funded strategy wallet, the agent holds no keys, and withdrawals are made by you in the app, behind MFA | Tie |

| Venues and spot | Perps on Hyperliquid and on Lighter from one account, spot buys and sells across the supported networks, outcome markets coming | Hyperliquid crypto perps plus the XYZ DEX stocks, pre-IPO names, metals, indices and FX, traded by the agent; no spot, no prediction markets | Infinex |
| Cashback | 60% of Infinex’s builder fee returned on every Hyperliquid trade | No fee to return: 0% Senpi fee on paid plans | Infinex |
| What it costs | Infinex publishes no rate card; on-chain, its perps builder code collected $20.2K on $40.4M of Hyperliquid volume in 30 days, about 0.05%, of which 60% comes back as cashback, so about 0.02% net (DefiLlama, Nov 7, 2026), plus Hyperliquid’s fees | Pro $50, Advanced $100, Quant $200 a month with AI credits; 0% Senpi trading fee on every paid plan, 0.03% on the free trial or without a paid plan; Hyperliquid’s own fees apply on top: 0.015% maker and 0.045% taker at the base tier on crypto perps, less at higher volume, and about 0.009% taker on most XYZ markets (GOLD, MSTR and three others cost 0.09%) (senpi.ai/fees) | - |

What Infinex is built for
A passkey account that feels like an exchange
No wallet, no seed phrase, created on any device, funded with any token on 25 networks without bridging, and self-custodial throughout.
Two perp venues and spot in one balance
Hyperliquid and Lighter perps, spot across the supported networks, with outcome markets announced.
Cashback on the fee
60% of Infinex’s builder fee comes back on every Hyperliquid trade, taking the on-chain fee to about 0.02% net.
The agent, and where you reach it
Infinex is an app you operate. Senpi is an agent you talk to, and the app is one of the places you talk to it.
| Criterion | Infinex | Senpi |
|---|---|---|
| Inside AI assistants | No integration | Senpi Connectors for Claude, ChatGPT, Grok, Hermes and Muse: one address and a Senpi sign-in, then your agent answers inside the assistant you already use |
| On the sites you read | The Infinex app only | Senpi Companion, a Chrome extension on 28 sites: X, Hyperliquid, TradingView, Binance, Coinbase, OKX and more |
| What the Companion does | Not applicable | Quant Desk on any wallet you see, the Signals brief for the asset on screen, and Trade the Take: a post or headline becomes a trade setup with size and stop |
| Phone | Web app on any device; no native app listed | iOS and Android apps |
Senpi's edge here
Infinex lives in its account. Senpi lives wherever you are: a Claude or ChatGPT conversation, a phone, or the X post that gave you the idea. If you already work in an AI assistant, this is the whole comparison.
Senpi Signals vs the terminal
Infinex shows you your own book well. Senpi shows you other people’s.
| Criterion | Infinex | Senpi |
|---|---|---|
| The read | Your PnL, margin utilisation and fills, rolled up; charts with drag-to-set exits | Senpi Signals: per asset, the biggest recent moves from proven wallets set against the broader cohort, scored, with the driver named |
| Other wallets | Not documented | Quant Desk: a score over six explained dimensions, a protection audit of the live book, leaks priced in dollars, on any Hyperliquid address |
| Alerts | Not documented | An alert when any wallet you add opens, adds or cuts, plus the agent’s own read before it trades |
| Where it reaches you | In the app | In the app, in Claude or ChatGPT, on the Companion while you read X or TradingView, and inside the agent’s reads |
Senpi's edge here
Infinex is a clean terminal for your own positions. Signals and Quant Desk read the wallets with a record and the market they sit in, and the agent acts on the read.
From an idea to a protected position
Building, running, following and protecting on perps.
| Criterion | Infinex | Senpi |
|---|---|---|
| Starting point | A market on the Pro ticket | A sentence: “short ETH when funding flips positive and open interest is at a 7-day high, max 2% of equity” |
| Building and running | You place every order; TP/SL dragged on the chart, reverse and close-all in a tap | The agent researches, writes the strategy, shows you the rules before anything opens, then a hosted runtime runs it 24/7 under a risk harness; edits apply live |
| Following a trader | Not documented | Mirror a trader you choose, after it researches their record, 0.1x to 4x, with the fee load checked and an exit attached |
| Exits and halts | TP/SL per position with expected PnL shown; no daily-loss or drawdown halt across the account | DSL on every strategy built from a rule or a template; cooldowns, optional daily-loss and drawdown halts per strategy; watch-only alerts on wallets you add |
Senpi's edge here
Infinex’s Pro terminal is one of the smoother manual experiences onchain. Senpi is for the trader who wants the strategy built, operated and protected. Neither product can promise a fill at a stop’s trigger price.
Account, venues and cost
Where Infinex is built to win, and what each costs.
| Criterion | Infinex | Senpi |
|---|---|---|
| Account | Passkey, no wallet, no seed phrase; fund with any token on 25 networks without bridging | Embedded wallet with exportable keys; card, Apple Pay, Google Pay or USDC on seven chains |
| Venues | Hyperliquid and Lighter perps, spot across the supported networks, outcomes coming | Hyperliquid perps only, including the XYZ DEX markets |
| Cashback | 60% of the builder fee back on every Hyperliquid trade | 0% Senpi fee on paid plans, so nothing to return |
| Cost of $250K a month of perps | About $50 net: 0.05% builder fee less 60% cashback, plus Hyperliquid’s 0.015% to 0.045% | $50 on Pro, whatever the volume, plus Hyperliquid’s 0.015% to 0.045% |
Winner: Infinex
If you want the smoothest account onchain, two perp venues and money back on the fee, Infinex wins and Senpi does not compete. On cost the lines cross near $250K of monthly perp volume after cashback: below it Infinex is cheaper per trade, above it the subscription is.
Where Senpi is stronger
An agent inside Claude, ChatGPT and your phone
Senpi Connectors for Claude, ChatGPT, Grok, Hermes and Muse, iOS and Android apps, and the Companion on 28 sites.
Signals from proven wallets
Per-asset reads of what wallets with a record are doing against the crowd, alerts on any wallet you add, Quant Desk on any address.
Strategies written, run and protected for you
From a sentence to a 24/7 runtime with DSL on every strategy built from a rule or a template and optional halts per strategy, and mirrors of traders you choose, sized by rule.
Which should you choose?
Choose Infinex if
- You want a passkey account with no wallet and no seed phrase
- You trade on Lighter as well as Hyperliquid, or want spot across many chains
- You trade by hand and want 60% of the fee back
Choose Senpi if
- You want your trading agent inside Claude, ChatGPT or your phone
- You want a Hyperliquid perp strategy written, run and protected for you
- You want proven-wallet signals and a wallet score, not only a view of your own book
Conclusion
Senpi is the agent. It writes the strategy from a sentence, runs it 24/7, protects every strategy built from a rule or a template with DSL and optional per-strategy halts, reads wallets with a record for you, and comes to you inside Claude, ChatGPT, Grok, Hermes or Muse, on your phone, or on the Companion while you read X or TradingView. For a trader who wants Hyperliquid perps run with help, that is the whole case.
Senpi Signals and Quant Desk give you a read Infinex does not try to: what proven wallets are doing against the crowd, scored, and a six-dimension score on any address, with the leaks in your own book priced in dollars.
Senpi’s price is flat: $50 a month on Pro with 0% Senpi fee, so a busy month costs the same as a quiet one, and above roughly $250K of monthly perp volume it is cheaper than Infinex’s fee even after the cashback.
Infinex is the better account for what it was built for: a passkey instead of a wallet, any-token funding across 25 networks, perps on Hyperliquid and Lighter from a CEX-style terminal, and 60% of the fee back. If that is your trading, Infinex; if your trading is Hyperliquid perps with an operator behind them, Senpi. One is an account you trade from; the other is an operator with an account attached.
Frequently asked questions
What is Infinex?
A self-custodial onchain account you create with a passkey, with no wallet connection and no seed phrase, that holds assets across 25 networks and trades spot and perps from one balance. Infinex Pro is its perps terminal on Hyperliquid and Lighter: 100+ markets, up to 40x, TP/SL dragged on the chart, and 60% of the builder fee returned on Hyperliquid trades.
What are Infinex’s fees?
Infinex publishes no rate card. On-chain, its perps builder code collected about $20.2K on $40.4M of Hyperliquid volume in the 30 days to Nov 7, 2026, about 0.05%, and Infinex returns 60% of that as cashback, so about 0.02% net, plus Hyperliquid’s own 0.015% to 0.045%. Senpi charges 0% on every paid plan (Pro $50, Advanced $100, Quant $200 a month), 0.03% on the free trial or without a paid plan, plus Hyperliquid’s fees.
Do I need a wallet to use Infinex?
No. You create the account with a passkey on Windows, an Apple device or Android, and fund it with any supported token on any of the 25 networks without bridging. Senpi creates a non-custodial wallet for you at sign-up and takes a card, Apple Pay, Google Pay or USDC on seven chains.
Does Infinex trade on Hyperliquid or Lighter?
Both, from the same account and balance: Infinex Pro routes perps to Hyperliquid and to Lighter. Senpi trades on Hyperliquid only, through the agent.
Does Infinex have copy trading or an AI assistant?
Neither is documented. Infinex is a manual terminal inside an account. Senpi is the agent: it writes and runs strategies, mirrors traders you choose, after it researches their record with sizing and an exit, and answers inside Claude, ChatGPT, Grok, Hermes and Muse.
Who should not pick Senpi?
Anyone who wants a passkey account with no wallet to manage, or trades on Lighter and spot across many chains. Anyone who trades by hand and values 60% of the fee back. And anyone trading a small book: below roughly $250K of monthly perp volume, Infinex costs less than a $50 Pro plan after cashback.
Can I run Senpi from Claude or ChatGPT?
Yes. Senpi Connectors put your Senpi agent inside Claude, ChatGPT, Grok, Hermes and Muse: you ask it to research a market, build or edit a strategy, review a wallet or close a position, and it does it on Hyperliquid without you opening the app.
What are Senpi Signals and the Senpi Companion?
Signals are per-asset reads of what proven wallets are doing against the broader cohort, scored and with the driver named. The Companion is a Chrome extension that brings Senpi onto 28 sites, including X, Hyperliquid, TradingView, Binance, Coinbase and OKX: Quant Desk on any wallet you see, the Signals brief for the asset on screen, and Trade the Take, which turns a post into a trade setup.
What is DSL?
Senpi’s dynamic stop. It starts at a loss-protection floor and moves the floor up as a position gains, so a trade exits on structure rather than on hope. No stop can guarantee a fill at its trigger price.
