What Is Arm Tokenized Stock (ARMc) and How Does It Work?
Arm Holdings is a UK-based company that designs processor architectures and licenses them to chipmakers rather than manufacturing chips itself. Its designs appear in smartphones, data center processors, and AI hardware. Arm's shares trade on Nasdaq under the ticker ARM, and the company is majority owned by SoftBank Group. ARMc tracks that Nasdaq exposure.
ARMc is part of Coinbase Tokenized Stocks, which went live on Base on August 24, 2026, and later added companies beyond the first U.S. tech names. It is not a synthetic derivative. Coinbase and Base state that each token is backed 1:1 by securities held with Alpaca, a regulated custodian, in bankruptcy-remote custody separate from Coinbase.
What you hold is a beneficial claim rather than full legal ownership. Reporting on the offering prospectus notes that holders receive no automatic voting rights. Corporate actions are reflected through an adjustment that leaves token balances unchanged, so ARMc keeps working inside lending pools and liquidity positions during those events.
Coinbase issues the tokens under Abu Dhabi Global Market (ADGM) regulation and offers them under Regulation S, so U.S. persons and residents of other restricted jurisdictions cannot buy them. Institutional market makers handle minting and redemption, while other users trade the tokens on onchain markets and transfer them freely.
Where to Buy Arm Tokenized Stock (ARMc): Exchanges and Trading Pairs
Coinbase tokenized stocks pair with USDC on Base. Aerodrome is the venue Base highlights for liquidity, and DEX routers such as 0x, 1inch, KyberSwap, and CoW Swap can route trades as well. Base keeps the official list of tickers, contract addresses, and venues at base.org/stocks.
ARMc pairs a high unit price with a very small supply. At the time of writing, CoinMarketCap shows a price near $240.06, a market cap of about $46,810, and just 195 ARMc in circulation across 62 holders. Its liquidity-to-market-cap ratio of 95.05% implies roughly $44,500 in pool liquidity, with 24-hour volume of about $4,500.
Prices have moved noticeably even over short periods. CoinMarketCap recorded an all-time high of $282.27 on October 13, 2026, and an all-time low of $210.84 on October 17. In one 24-hour window, ARMc traded between $223.95 and $240.58, a swing of more than 7%.
The three points below cover the market factors that most affect where and how you should buy ARMc.
- Main Exchange: Aerodrome on Base hosts the main USDC liquidity for Coinbase tokenized stocks. Reach it from the venue links on base.org/stocks, and confirm both your wallet and Aerodrome are on Base before trading.
- Is the Liquidity Locked? Market makers and liquidity providers supply the pool, and there is no team lock to check. Depth can change quickly, so review the pool size and your price impact before every trade, especially for larger orders.
- How to Spot Fake Tokens: Coinbase-issued stock tokens on Base use addresses beginning with 0xB200. The short ticker "ARM" can match unrelated tokens in search results, so always paste and match the full ARMc address rather than searching by symbol.
How to Buy Arm Tokenized Stock (ARMc): Step-by-Step Guide
The five steps below show how to buy ARMc with USDC on Base. Before you begin, confirm that you are not a U.S. person or a resident of another jurisdiction where these tokens are restricted.
-
Step 1: Set Up a Base-Compatible Wallet
Choose a self-custody wallet that supports Base, such as Trust Wallet (listed on CoinMarketCap), Base App, or MetaMask, and install it from the official source. Write your recovery phrase on paper, keep it offline, and never share it with anyone or type it into a website.
Add Base to your wallet and switch to it. Base addresses look like Ethereum addresses, but each network keeps its own balances. Most exchange-hosted accounts cannot connect to Aerodrome, so you need a self-custody wallet where you control the keys.
-
Step 2: Add USDC and ETH on Base
Buy USDC on an exchange that supports Base withdrawals, and select Base as the network. If your USDC sits on another chain, move it using a reputable bridge. Send a small test amount first and confirm it arrives before transferring the rest.
You also need a small amount of ETH on Base to pay gas fees. Base fees are generally low, but approvals and swaps fail without ETH. Since ARMc trades around $240, you will likely buy a fraction of a token, which works normally onchain.
-
Step 3: Go to Aerodrome and Connect Your Wallet
Open base.org/stocks and follow its Aerodrome link, or type the Aerodrome address directly. Avoid ads in search results, which are a common way scammers spread fake DeFi sites. Confirm the genuine domain appears in your address bar before connecting.
Click "Connect," pick your wallet, and approve the connection. Check that Aerodrome shows Base as the active network. Connecting simply shares your public address, and no funds can move until you review and approve a specific transaction in your wallet.
-
Step 4: Paste the Official ARMc Contract Address
Set USDC as the token you are spending. In the receiving field, paste 0xB20000000000000000000026215D755356E5043f instead of searching for "Arm" or "ARM," since those terms can match unrelated tokens and tokenized stocks from other issuers.
Confirm the token displays as ARMc and that its address starts with 0xB200. Compare it against base.org/stocks and CoinMarketCap character by character. If the ticker or any part of the address is different, stop and verify your source before continuing.
-
Step 5: Set Slippage and Swap USDC for ARMc
Enter your USDC amount and review the quoted price and price impact. Compare the quote with Arm's latest Nasdaq price, since ARMc's small pool has moved several percent within a day. Set slippage around 0.5% to 1%, and raise it only slightly if the swap fails.
Approve USDC if asked, then click "Swap" and confirm in your wallet. Once the trade settles, open it on BaseScan and check that the tokens came from the official ARMc contract. Add ARMc as a custom token if your wallet does not display it.
Is Arm Tokenized Stock (ARMc) Safe? Risks to Know Before Buying
ARMc rests on 1:1 backing, regulated custody, and one of the most important companies in the semiconductor industry. That foundation is solid, but you still carry Arm's own stock risk, which is shaped by AI enthusiasm and high valuations, plus the risks of a small onchain market.
The risks below are specific to ARMc's profile as a high-priced, low-supply AI chip stock token on Base.
- Low Liquidity and Price Swings: With 195 tokens and about $4,500 in daily volume, ARMc can trade away from Arm's Nasdaq price. A single sizable order may move the pool, and intraday swings of more than 7% have already occurred.
- Smart Contract Risks: Published materials state that Base and Spearbit reviewed the B20 standard. Your tokens still depend on the token contract, the DEX you use, and any lending protocol you deposit into, and a flaw in any of these could cause losses.
- Risk of Losing Your Money: Arm's shares respond to smartphone demand, AI and data center spending, licensing deals, and shifts in investor sentiment toward chip stocks. ARMc follows those moves and can also shift on weekends, when Nasdaq is closed but onchain pools stay open.
The 24/7 appeal works in both directions for a stock like Arm. Major AI or semiconductor news can break at any hour, and ARMc lets you react before Nasdaq opens. That same feature means weekend prices can gap sharply from Friday's close, especially in a pool this small.
Conclusion
Buying ARMc means setting up a Base wallet, adding USDC and a little ETH on Base, and swapping on Aerodrome using the contract 0xB20000000000000000000026215D755356E5043f. Always verify that address on base.org/stocks and CoinMarketCap, and compare your quote with Arm's Nasdaq price before you confirm.
ARMc gives eligible non-U.S. investors 1:1 backed exposure to a leading chip designer with round-the-clock access. Its supply and liquidity are limited at the time of writing, so buy in small amounts, watch for gaps against the real share price, and remember it is closed to U.S. persons.
