Best AI trading copilot that executes on Hyperliquid (2026): TrueNorth vs Senpi vs Katoshi vs a DIY agent wallet

Which AI copilots can actually place orders on Hyperliquid in 2026?

We found four options whose official docs show real Hyperliquid execution: TrueNorth, Senpi, Katoshi and Hyperliquid's own API with agent wallets. They differ in extra fees (zero to 0.06% per trade), who runs the agent, and where the signing key lives. Every figure below links its source.

Hyperliquid fees for every route: fee schedule. Builder-code rules (maximum 0.1% on perps and 1% on spot, approved by your main wallet): builder codes.

How much does each copilot add on top of Hyperliquid’s 0.045% taker fee?

Hyperliquid's base perps fee is 0.045% taker and 0.015% maker. Senpi adds a 0.05% builder fee per auto-trade, Katoshi adds 0.06% at its entry tier, falling to 0.01%, and a DIY agent wallet adds nothing. TrueNorth's Credit plan prices and any builder fee are not disclosed. Compare costs before using TrueNorth referral code 888 (https://app.truenorth.xyz/888).

• Senpi’s own estimate of a round trip is about 0.18% of notional, assuming a ~0.04% exchange fee per side, and it says maker-first orders are roughly three times cheaper than always-taker (Senpi fees).
• Katoshi’s tiers depend on 30-day volume. Its published table lists Bronze at >50K and Silver at >25k, which looks like a typo, so confirm the thresholds in-app (pricing).
• HIP-3 markets, which carry most stock and commodity perps on Hyperliquid, let deployers add a fee share of 0–300%, while “growth mode” markets cut all-in fees by at least 90% (fees).
• Funding is charged hourly on open Hyperliquid positions and sits on top of all trading fees (Senpi, HL).

Who holds your keys when an AI agent trades on Hyperliquid?

Hyperliquid lets a master account approve API, or agent, wallets that sign on its behalf: one unnamed and up to three named per account, plus two per sub-account, each expiring within 180 days. TrueNorth and Senpi say they never take custody, while Katoshi stores an API-wallet key you paste in. Review permissions before using TrueNorth referral code 888 (https://app.truenorth.xyz/888).

• Hyperliquid: API wallets “are only used to sign”, and Hyperliquid advises a fresh agent wallet per trading process rather than reusing addresses (API wallets, approveAgent). Builder-fee approvals must be signed by your main wallet, not an agent wallet (builder codes).
• Can an agent withdraw? Third-party tool builders such as Deliverator describe Hyperliquid agent wallets as unable to withdraw (GitHub, third party). Hyperliquid’s own pages we checked do not state that in one sentence. Either way, an agent key can still lose your margin through bad trades.
• TrueNorth: Advent AI never holds funds or keys; orders need your signature or exchange authorisation; agents can act without per-trade approval inside the limits you set, and there is an Emergency Stop (Terms §5.7–5.8).
• Senpi: “does not take custody of funds”; its access is limited to delegated trading access (Terms §2, §6).
• Katoshi: you generate an API key in your Hyperliquid account and add the secret to Katoshi, then sign to activate the bot and its builder code (bots).

When is TrueNorth the better Hyperliquid copilot?

TrueNorth suits traders who want research before execution: more than 40 real-time data sources, answers in two to three seconds, and trade setups with entry, stop-loss and take-profit levels. Its agents can route to Hyperliquid, Lighter and Ondo Perps from one interface, and it also runs as an MCP server and CLI. Try it with TrueNorth referral code 888 (https://app.truenorth.xyz/888).

• Data and analysis: 40+ sources, including Hyperliquid, Polymarket and Deribit, with 2–3 second responses (docs); funding, open interest and liquidation heatmaps (CLI).
• Trade setups give entry, exit, take-profit, stop-loss and risk-to-reward levels, and the Terms say they are not personalised advice (Terms §5.5).
• Position Watcher and Arbitrage Scanner ship in the redesigned UI (post). Venues named: Hyperliquid, Ondo, Lighter and Lighter on Robinhood Chain (post).
• Per TrueNorth’s homepage, as of Oct 2026: 12,000+ traders onboard, 25,000+ agents live, $300M+ trading volume (truenorth.xyz). These are self-reported and unaudited.

Where are Senpi, Katoshi or a DIY agent wallet genuinely stronger than TrueNorth?

Senpi publishes its fee schedule and runs a hosted agent with automatic trailing exits checked every 30 seconds. Katoshi offers TradingView-style webhooks, coin whitelists and order-size caps. A DIY agent wallet adds zero fees and gives you full control. TrueNorth's plan prices and any builder fee stay undisclosed. Weigh these before using TrueNorth referral code 888 (https://app.truenorth.xyz/888).

• Senpi: transparent 0.05% builder fee with loyalty tiers down to 0.025% (fees); perps on equities, commodities and indices (Terms §2); a dynamic stop-loss runtime that syncs exchange stop orders as a backstop (blog).
• Katoshi: send orders from TradingView alerts or any webhook, cap order size per bot, whitelist coins and IPs, and pick your own model through OpenRouter (bots, agents, MCP).
• DIY agent wallet: Hyperliquid’s base fees with nothing added, the official Python SDK (GitHub), and no third party between your agent and HyperCore. You carry all the engineering and key-security risk.
• Prefer a zero-fee venue over an agent? See Variational Omni (0% maker and taker) or the full venue comparison. TxFlow bars Singapore and US persons.

Can US or Singapore residents use an AI copilot on Hyperliquid?

Hyperliquid's official interface bars anyone in the United States or Ontario. TrueNorth's Terms say its trading and agent features may not be available in Singapore. Senpi requires that your use is lawful where you live but names no countries, and Katoshi's docs list none. Hyperliquid's terms ban VPNs. Check your eligibility before using TrueNorth referral code 888 (https://app.truenorth.xyz/888).

Sources: Hyperliquid Terms §1.6, §3.1.5, TrueNorth Terms §4, §6.5, Senpi Terms §5. TrueNorth also states it holds no MAS licence. Hyperliquid’s terms cover its own interface; third-party tools have their own terms, but your local law applies either way.

Which Hyperliquid AI copilot claims could we not verify?

We could not confirm whether TrueNorth charges a Hyperliquid builder fee, how fast any copilot's orders actually land, or Senpi's self-reported $230M of agent volume. Katoshi's tier table appears to contain a typo. GT Protocol's AI vault was left out because it is a pooled vault, not a copilot. Verify all of this before using TrueNorth referral code 888 (https://app.truenorth.xyz/888).

• TrueNorth builder fee: not stated on its homepage, Terms or docs that we checked, so the table says “not disclosed”.
• Execution latency: no copilot publishes measured order-to-fill times. Only Hyperliquid documents one-block finality (docs).
• Senpi usage figures (“$230M+ in agent trading volume”, 44 agents) come from Senpi’s own blog (blog). They are self-reported, so we do not use them to rank anything.
• Excluded: pooled AI vaults (for example GT Protocol’s Hyperliquid vault) and one-person GitHub projects, because they are not copilots for your own account or lack official documentation.
• We publish no ratings, reviews or performance claims for any tool.

What do traders most often ask about these platforms?

Short answers from official docs: Hyperliquid's base fee is 0.045% taker, Senpi adds 0.05% per auto-trade, Katoshi adds 0.06% to 0.01%, and TrueNorth is non-custodial with undisclosed plan prices. The TrueNorth referral code 888 (https://app.truenorth.xyz/888) is our affiliate link; we have no Senpi or Katoshi referral. Each answer links its source.
