Cryptominium Profile. What we have established, measured and written about BAT, and what we have not.
- Measured
- Selling $100,000 on 2 exchange order books lost between 0.56% and 4.78%, on 3 November 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.
- 6 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 BAT
Selling $100,000 of BAT into each exchange’s resting bids, measured against the mid price:
| Exchange | Lost | Got back | Measured |
|---|---|---|---|
| Kraken BAT/USD | 0.56% | $99,440 | 2026-11-03 |
| Coinbase BAT/USD | 4.78% | $95,221 | 2026-11-03 |
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 BAT 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 Basic Attention is
Basic Attention Token (BAT) is an ERC-20 token tied to an open-source, decentralized ad exchange platform built on Ethereum. It held an initial coin offering on May 31, 2017, raising approximately $35M USD in less than 30 seconds. The project was created in 2016 by a team including Brendan Eich, creator of JavaScript and co-founder of Mozilla, along with Brian Bondy and Scott Locklin. Its stated aim is to address problems in digital advertising, which the project describes as broken, fraudulent and opaque.
BAT works by having advertisers pay the token to website publishers in exchange for user attention. Ad targeting runs locally on a user's device through BAT Ads, rather than through third-party tracking, with attention measured via analytics and machine-learning components. The token is most closely associated with Brave, an open-source browser that blocks trackers and malware and uses blockchain-based logging to attribute attention and route rewards to publishers, with tracking data reportedly stored only on the user's own device.
BAT is deployed across multiple chains, including Ethereum, Avalanche, Polygon, Solana, Near Protocol, Harmony and Energi, which means its utility depends on integration and bridging across these networks rather than a single settlement layer. It functions as a payment and reward mechanism within the Brave ecosystem specifically — it is not a general-purpose currency, and its usefulness outside of ad-attention tracking and Brave-linked applications is not established by the source material. The on-device, privacy-preserving design means attention measurement cannot be independently audited by outside parties in the way a public ledger transaction can. Nothing in the record describes revenue-sharing, staking yield, or governance rights beyond its role as a medium of exchange between advertisers, publishers and users.

Our own measurement · measured 3 November 2026
BAT does not run applications. It is a token on Ethereum that serves as the unit of exchange in the advertising system of the Brave browser: advertisers pay in it, and users can opt to receive it for viewing ads.

BAT's white paper sets a cap of 1.5 billion tokens and says no new tokens will be created once the pool set aside for users is used up. Its site says over 99% of that total is now in circulation.

Where BAT lives
On Solana, a mint authority can create more of the token and a freeze authority can freeze it in a holder's account; both are read from the token itself, every day. 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.
