Arcus pTokens Explained: Tokenized Leverage on Robinhood Chain

A leveraged perp position is something you maintain: margin to watch, funding every hour, a liquidation price that follows you around. Arcus's answer, launched on August 26, 2026, is the pToken: an ERC-20 on Robinhood Chain that wraps an Arcus perpetuals account running one fixed strategy. Buy pBTC3x and you hold a share of an account that keeps itself at 3x long BTC. There is no account of your own to open and no margin to post. You hold a token, and the token's value moves with the strategy, costs included.

This guide covers the live list, how NAV is built, what you pay, and the one piece of arithmetic every leveraged-token holder should run first.

What a pToken is

Arcus's launch post, pTokens: A New Primitive on Arcus, defines it plainly: "A pToken tokenizes an Arcus perpetuals account into an ERC-20 on Robinhood Chain, so that shares of that account can trade freely on spot venues." Your balance is a pro-rata share of everything that account holds, measured against total supply.

The first generation keeps the strategy narrow. Each pToken covers one market at one target leverage, both fixed when the vault is created. The account rebalances itself on a drift threshold rather than a daily clock: when exposure moves far enough off target, it trades back. In a volatile hour that can happen several times; on a quiet day, not at all. The post argues this keeps a falling position from compounding toward liquidation between scheduled rebalances.

For builders, the contract follows the ERC-4626 vault interface and specifically ERC-7540, the asynchronous vault standard, because minting and redeeming are not instant. That makes a pToken usable anywhere ERC-20s work: an AMM pair, a lending market's collateral list, a wallet.

Arcus added a Vaults section to the web app on August 28 (frontend changelog). It lists each pToken with its NAV, a 24-hour sparkline, all-time return, TVL and deposit and withdraw buttons.

Two columns on that page are easy to misread. All-time return runs from the day each vault was created, so a vault launched in August and one launched in late September are not comparable side by side. And 24h performance on a 5x vault is a five-times-levered day, which means a quiet day for GME can still show a large swing on pGME5x. The Age column is your guide to how much history a number rests on: at the capture, the GME, GLD and SPCX vaults were 7 to 9 days old. The My Vaults tab shows only the vaults your connected wallet holds.

The live pToken list

The naming is consistent: p for long, s for short, then the market, then the leverage. Data below is from GET https://api.vaults.arcus.xyz/v1/vaults, pulled 2026-10-02 at about 04:34 UTC.

Those twelve add up to about $994K. The API also returns two test vaults (pTEST and pTESTR) and two small SPCX vaults named "5x" that are configured at 3x leverage and hold under $1,100 between them; I left those out. No vault takes a profit share (profitShareBps is 0 across the board). DefiLlama tracks the same pool as "Arcus pTokens" at roughly $0.99M.

For scale: Arcus says the whole exchange holds "$25M+" to "$28M+" in total value locked (its two October 1 posts give different figures). pTokens are a small corner of it, and the thinnest vaults hold a few tens of thousands of dollars.

How NAV works

NAV is what one pToken is worth: the account's positions plus any cash, divided by every token in issue. Arcus is clear that "NAV is not the price of the underlying market. It is what holding the position actually earns and costs." Three things move it. The market comes first: over short horizons a 3x long gains or loses roughly three times the underlying's move. Funding comes next. The account pays or collects hourly perp funding, and it flows straight into NAV, so when longs are paying, a 3x long BTC vault pays three times what a 1x position would. Last, every rebalancing trade pays fees and slippage, and those come out of NAV too.

New tokens are minted at an oracle-signed NAV, never at a stale number. Arcus describes the flow in five steps:

Redemptions run the same path in reverse. That is the primary market. Arcus calls the secondary market "the route in and out" for holders: buying and selling the token on Arcus or on a Uniswap pool, which Arcus says is "open to everyone from day one."

On the secondary market, what you pay is the market price, not NAV. Arcus warns the two "may diverge for two reasons: liquidity can be thin, and supply does not expand the moment demand does." Its advice is short: "Check both numbers before you trade. The distance between them is information." Buying above NAV means paying a premium the arbitrage may later close.

What you pay

Funding rates on Arcus are covered in the fees guide, and current rates are on the funding rates tool.

Volatility decay: the arithmetic to run first

A leveraged token resets its exposure as prices move. After a rise it holds more exposure; after a fall it holds less. That is what keeps it at 3x, and it is also why a 3x token does not return three times the underlying over longer periods.

Take the simplest case: the underlying rises 10% one day and falls back to its starting price the next (a 9.09% drop). Assume the vault rebalances once at each day's end, and ignore funding and fees.

The underlying went nowhere. The 3x long lost about 5.5% and the 3x short lost about 11%. Repeat that chop for a few weeks and the losses compound; a 5x token decays faster still. pTokens rebalance on thresholds rather than at a daily close, so real results follow the actual price path, but the direction of the effect is the same. Leveraged tokens reward trends and punish range-bound markets.

Other risks worth naming

Each vault has a manager address that accepts mints and redemptions, and an off-chain oracle signs the NAV. The audits Arcus lists (Trail of Bits and OpenZeppelin) cover its rootchain contracts. I found no published audit of the pToken contracts themselves, which is worth weighing before you park real money in one.

Exits are the other thing to plan for. Primary redemptions are asynchronous and large ones fill in parts, so in a fast market the secondary pool may be your only quick way out, at whatever price it offers. Several vaults hold well under $100K, and a big sell order into a small pool moves the price against you.

Finally, threshold rebalancing lowers liquidation risk. A sharp one-way move in the wrong direction still costs you three or five times the underlying's loss.

Listed on CoinGecko and DexScreener, but not "the Arcus token"

Search "Arcus token price" and pTokens are often what you find. CoinGecko lists five of them: PBTC, PBTC3X, SBTC, SBTC3X and PHOOD3X (ids such as arcus-btc-3x-long and arcus-hood-3x-long). DexScreener shows their Uniswap pools on Robinhood Chain, including pGME5x and pSPCX3x.

These are official Arcus vault tokens. They are not a governance token, they give no claim on Arcus's revenue, and they say nothing about a future airdrop. Arcus's Help Center states that Arcus "does not currently have a token." The ARCUS ticker on CoinGecko belongs to Arcus Network, an unrelated AI-payments project, and several fake "Arcus" tokens trade on Robinhood Chain itself. If you are verifying a pToken, match the contract address against the Vaults page in the app; for example, pHOOD3x is 0xe24cabdf76dd1c2576049167eb1755c84b985c36.

pTokens are not an HLP-style liquidity vault

On Hyperliquid, "vault" usually means HLP, a pooled vault that makes markets, takes over liquidations and shares the result with depositors (HyperliquidGuide's HLP explainer covers it in depth). Arcus works differently. Its Help Center says order book liquidity comes "from anchor market makers quoting directly on the matching engine, not retail liquidity providers (LPs) in vaults."

If you want yield from providing liquidity, pTokens are the wrong tool. If you want leveraged exposure without running a perps account, that is the job they do.

How to get pTokens

You need USDG on Robinhood Chain and access from an eligible region; Arcus restricts the US, Canada, the UK and sanctioned regions. From there, open Arcus, go to Vaults, pick a token and deposit, or buy it on the secondary market. How to deposit on Arcus covers funding, and what is Arcus covers the wider product. If you would rather run the position yourself, how to trade on Arcus explains the perps side, which needs an invite code or waitlist slot.
