CM Profile: Arbitrum
Cryptominium Profile. What we have established, measured and written about ARB, and what we have not.
- Measured
- Selling $100,000 on 2 exchange order books lost between 0.23% and 0.24%, on 8 October 2026.
- Its price, recorded by us every day since 9 August 2026.
- Written, with sources
- Not established
- What an on-chain sale would return on Ethereum. It trades mostly off-chain there, so we do not measure it on-chain.
- 2 of its chains are not among the 3 we read.
- Whether it can be held without a company. We have no sourced answer yet.
- 5 other questions about what it can do have no written answer. Some may not apply to it.

What it actually costs to sell ARB
Selling $100,000 of ARB into each exchange’s resting bids, measured against the mid price:
| Exchange | Lost | Got back | Measured |
|---|---|---|---|
| Kraken ARB/USD | 0.23% | $99,773 | 2026-10-08 |
| Coinbase ARB/USD | 0.24% | $99,761 | 2026-10-08 |
Exchange figures need an account there (and KYC, a permitted country, the tokens already deposited), are before trading fees, and are never averaged with the on-chain figure. Binance is not included: it refuses requests from the region our servers are in. How this is measured →
Watch this number instead of remembering it. A free account keeps ARB on a list, records where it stood the day you added it, and emails you if selling it on these exchanges gets materially harder — one message, not a series. The measurement itself stays public; the account is for being told when it moves without you looking.
What Arbitrum is
Arbitrum is a layer-2 network built by Offchain Labs to make Ethereum cheaper to use. Transactions are executed on Arbitrum, then compressed and posted back to Ethereum, so users get much lower fees while the record ultimately lives on the main chain.
It is an optimistic rollup, and the word optimistic is literal. Results are assumed valid and published without proof, and a challenge window opens during which anyone can submit evidence of fraud. That is why moving funds back to Ethereum through the official bridge takes about a week — the wait is the security model, not a queue.
Several things are commonly misread. The ARB token is for governance; gas on the network is paid in ETH, so holding ARB is not required to use it. The sequencer that orders transactions has been operated centrally, which means the party running it can in principle delay or reorder transactions — it cannot steal funds, and decentralising it has been a stated goal for years. And the contracts governing the chain are upgradeable by a governance process, so the guarantees rest on that process as much as on the mathematics.

Our own measurement · measured 8 October 2026
ARB does not run applications, and it does not pay the fees on the Arbitrum network, which are paid in ether. It gives its holders a vote in the body that governs the network.

ARB was created with a supply of 10 billion. Holders can vote to create more, at most 2% of the supply a year.

Where ARB lives
On Ethereum, Base and BNB Chain, GoPlus's analysis of each contract is read weekly: whether it has a function to block addresses or pause transfers, and whether an owner holds it. That is GoPlus's reading, not ours. Where a token exists on several chains, one copy's settings say nothing about the original coin.
Always verify a contract address against the project's own site before sending anything. Addresses are shown as published by CoinGecko, not as an endorsement — and identical-looking tokens on other chains are the most common way people lose money here.
