Toshi and Brett are two separate meme tokens issued on Base, the Ethereum layer-2 network built by Coinbase. TOSHI is a cat-themed token whose own site calls it the face and mascot of Base; BRETT is a comic-character token that CoinGecko describes as a fan tribute and an unofficial mascot. This article sets out what each one is, what its token actually does, where it trades, and how to check every claim yourself.
What Is Toshi and What Is Brett?
Both are ordinary ERC-20 tokens on Base. Neither is a blockchain, a company, or a product with a service behind it. Toshi's own documentation states that $TOSHI is a memecoin named after Coinbase co-founder Brian Armstrong's cat and the pseudonymous creator of Bitcoin, Satoshi Nakamoto, and Coinbase's own asset page for TOSHI carries the same naming story in almost the same words. A name is all that follows from a name. Toshi is not a Coinbase product, not an official Base token, and holds no licence or authorisation from either. The line that it serves as the face and mascot of Base appears on toshithecat.com and in the project's GitBook, which makes it the project's claim about itself, not a status anyone granted it. An exchange listing is not an endorsement either.
Brett takes its character from Matt Furie's comic Boys' Club, the same strip Pepe comes from. CoinGecko's description says the token is presented as a fan tribute, calls it the unofficial mascot of the Base network, and states in its own risk note that the project is a fan tribute and is not officially affiliated with the original creator of the Boys' Club comic. BaseScan's overview for the contract repeats the character description without asserting any licence. Two tokens, one network, two borrowed cultural references, and ownership of neither.
What Problem Do Base Meme Tokens Claim to Solve?
Before Base opened to the public in 2023, the early culture of a new chain was usually carried by NFT collections and by whichever token happened to trade first, and on Ethereum mainnet the fees made that kind of low-stakes activity expensive. A cheap layer-2 changes the arithmetic: deploying a token costs almost nothing, so a chain accumulates symbols quickly. That is the whole of the category these two belong to.
Neither project claims to solve a technical problem, and it would be dishonest to invent one for them. Toshi's stated ambition, in its own wording, is to become the face of Base and to evolve from a memecoin into an essential project on Base, which is a claim about branding and community rather than throughput or security. Brett's aggregator listing describes cultural adoption on Base and nothing more. Read both as what they say they are: a bid for attention on a network, made by people who chose not to identify themselves.
How Toshi and Brett Work on Base
Mechanically these are the simplest tokens there are. Each is a single standard ERC-20 contract deployed on Base with 18 decimals, and each has verified source code on BaseScan, meaning the published Solidity matches the deployed bytecode. Verification is a match check, not an audit and not a safety statement. TOSHI is at 0xAC1Bd2486aAf3B5C0fc3Fd868558b082a531B2B4 and BRETT is at 0x532f27101965dd16442E59d40670FaF5eBB142E4. Read on 14 August 2026, BaseScan reported 1,088,380 holder addresses for TOSHI and 903,503 for BRETT, and labelled the token reputation Neutral for TOSHI and Unknown for BRETT.
CoinGecko also lists a second contract for each token on BNB Smart Chain, at addresses that are not the Base ones: TOSHI at 0x6a2608Dabe09bc1128EEC7275B92DFB939D5Db3f and BRETT at 0xa7440029eca41deabd8775ef1d6086b37d4df8d6. Same name, same ticker, different chain, different bytecode. That gap is the most common way people end up holding something other than what they meant to hold. The identity of a token is the address plus the network, and nothing shorter than that is an answer.
What TOSHI and BRETT Do in Their Own Systems
Neither token pays for gas, because transactions on Base are paid in ETH, and neither is required to use any service. TOSHI's documented role is a governance one. The project's GitBook describes MEOW DAO, in which one token is one vote, and records two Snapshot votes: one directing an Optimism Superchain Creators grant onward to Stand With Crypto, and one removing the token's transfer tax. That second vote is why the tokenomics page now records a 0% buy and 0% sell tax against a previously stated 3%/3%. The same page gives total supply as 420,689,999,999 TOSHI with the maximum supply already circulating; the on-chain figure on BaseScan on 14 August 2026 was 420,689,980,957.
BRETT has no documented on-chain function at all. There is no staking, no fee capture, no burn, and no treasury decision a holder votes on. The project also publishes nothing that can be read directly: on 14 August 2026 basedbrett.com returned no readable page body to a fetcher, only a Google Tag Manager block, so the launch allocation repeated across third-party explainers could not be confirmed from the project itself and is not reproduced here. BaseScan gives a maximum total supply of 9,999,997,544 BRETT. Any allocation, lock or renouncement figure you see elsewhere should be treated as unsourced until the project publishes it on a page you can actually open.
Base Ecosystem Presence and Where Each Token Trades Today
Adoption for these two means listings and liquidity, because there is nothing to integrate. On 14 August 2026 CoinGecko tracked TOSHI across 41 exchanges and 55 markets, and BRETT across 52 exchanges and 61 markets. TOSHI trades on Coinbase Exchange, where the TOSHI/USD book showed a 0.10% spread with roughly $37,285 of depth within 2% above the mid and $62,620 below it; it also trades on Upbit against the Korean won, and on Kraken, whose public asset-pairs endpoint returns TOSHI/USD with a status of online. BRETT is not listed on Coinbase, and the same Kraken endpoint answers a BRETT/USD query with an unknown-asset-pair error.
Headline volume has to be discounted before it means anything. CoinGecko put BRETT's 24-hour volume at about $3.94M on 14 August 2026, but $1,719,910 of it, or 41.04%, came from a single DigiFinex BRETT/USDT book that at the same moment showed a 24.64% spread and $0.00 of depth within 2% on both sides. A book with a quarter-point spread and no measurable depth cannot absorb the size its volume implies. Measured on-chain instead, DexScreener's Base pairs for BRETT summed to roughly $181,000 over the same 24 hours, with the deepest pool a Uniswap v3 BRETT/WETH pair holding about $888,000. TOSHI's on-chain side is thinner still, roughly $39,600 across its Base pairs against a deepest pool of about $905,000, which tells you most of its reported activity happens on centralised venues.
How the Two Tokens Differ from Each Other
The first difference is the source of the reference and the exposure that comes with it. Toshi borrows a private person's pet and a pseudonym, so there is no rights holder positioned to object, and Coinbase's own page describes the naming without conferring anything. Brett borrows a drawn character from a living artist with a documented history of enforcing his copyright, and the aggregator that lists it states in writing that the project is not officially affiliated with him. Matt Furie has pursued Pepe-related claims before, including a 2018 copyright suit against Infowars. No lawsuit, cease-and-desist or warning letter directed at BRETT was found in this round of checking, and CoinGecko's news feed records only that Furie referenced the Brett character in early August 2026. A reference is not a licence and not an endorsement.
The second difference is where the trading actually happens. TOSHI's flow is concentrated on centralised venues including Coinbase, Kraken and Upbit, so its price discovery is mostly off-chain and its on-chain pools are quiet. BRETT's largest single reported book sits on a venue with no measurable depth, while its verifiable trading is the small on-chain figure above. Those are different market structures with different failure modes, not a ranking.
Risks and Limitations
Start with who is behind them, which is nobody publicly. Neither project names a single team member on its site or in its documentation. Toshi's site offers an admin mailbox and a DAO framing and no people; Brett's site serves no readable content at all. An anonymous team cannot be held to a commitment, and if an anonymous project stops maintaining its channels, holders are left with a contract and no counterparty.
Then the code. No public audit of either token contract was found in this round. Toshi's documentation does link a Halborn security assessment, but that assessment is scoped to Toshi Tools, meaning the project's separate launcher, locker and multisender contracts, not the TOSHI token itself, and the PDF is hosted on the project's own domain rather than on the auditor's site. For BRETT no audit report was found at all. Treat both as unaudited for the purposes of the token contract.
Then the market and everything around it. Aggregate volume for both tokens is inflated by venues whose order books cannot support it, as the DigiFinex figures above show, and outside a handful of books the depth within 2% is measured in single-digit thousands of dollars. Both are pure meme assets with no revenue, no product and no cash flow, so nothing underpins them when attention moves elsewhere. The intellectual-property exposure sits specifically on the Brett side, where the reference is to a living creator who has litigated over the same comic universe. Listings can be withdrawn without notice, meme assets are treated differently by regulators in different jurisdictions, and this article makes no claim about how either token is classified anywhere.
How to Verify Toshi and Brett Yourself
Start at the official domains, typed into the address bar rather than reached from a search result or an advertisement: toshithecat.com and its linked GitBook for Toshi, basedbrett.com for Brett. Use the official site as the origin for every social account and every exchange link, because the direction from the official domain outward is evidence and the reverse is not. Compare any domain you land on character by character with the one you meant to visit, and if a page reached from a message, a reply or an ad asks you to connect a wallet to claim, migrate or verify anything, stop there. Note that basedbrett.com currently renders nothing without JavaScript, so most of what circulates about Brett has no readable first-party page behind it.
Then pin the contract and the network together. Paste 0xAC1Bd2486aAf3B5C0fc3Fd868558b082a531B2B4 or 0x532f27101965dd16442E59d40670FaF5eBB142E4 into BaseScan and confirm the token name, the symbol, 18 decimals, the holder count, and that the source code is verified. If a page or a wallet shows a different address, it is a different token even when the ticker matches, and the BNB Smart Chain entries on the same aggregator pages are exactly that case. Never take a contract address from a chat message, a reply or a screenshot.
For supply, read the chain rather than an aggregator, since the max total supply field on the explorer is the on-chain number and a project page can be stale. For audits, look for the report on the auditing firm's own site and read what it covers, because an assessment of a project's separate tools says nothing about the token contract. For liquidity, open the pool on a decentralised-exchange explorer and read pool size and 24-hour volume together, then compare that with whatever aggregate figure an aggregator shows.
Finally, grade the market data instead of copying it. On any exchange table, read the spread column and the plus-2% and minus-2% depth columns next to the volume column, and discount any venue that reports large volume with a wide spread and zero depth. Write down the date of every figure you take, because all of it moves. And treat any sentence about official status, whether mascot, partner, endorsed or licensed, as a claim that needs a document from the party supposedly granting it rather than from the project.
Conclusion
Toshi and Brett are two separate ERC-20 meme tokens on Base, both run by teams that have not identified themselves, both without a product, and with no documented on-chain utility beyond the token-weighted vote on Toshi's side. Toshi is named after a Coinbase co-founder's cat and Bitcoin's pseudonymous creator and calls itself the face of Base; Brett is a fan tribute to a Matt Furie character that its own aggregator listing describes as an unofficial mascot with no affiliation to that creator. Neither name is a grant of status by Coinbase, by Base or by anyone else. Before relying on anything written here, put both contract addresses into a Base block explorer yourself, and read exchange spread and depth before you read volume.
