Fomo Base: Coinbase's chain, without the wallet setup
Fomo Base support has been in the app since September 2025, the second chain it ever added. You buy Base memecoins like TOSHI, BRETT and DEGEN, the Clanker launches and the AI agent tokens, from the same USD balance as your Solana trades, with the gas paid by Fomo and a 0.5% fee that drops to 0.45% with referral code GEMQUEENX. This page covers what trades on Base inside Fomo, how a buy works, what it costs, and where a thinner chain bites.

Fomo Base: key facts
- In Fomo sinceSeptember 2025, the first chain added after Solana. Fomo called it going multichain.
- The chainCoinbase's Layer 2 on the OP Stack, settling to Ethereum. Blocks every two seconds, with sub-second preconfirmations through Flashblocks.
- What tradesAny Base token with a pool: TOSHI, BRETT, DEGEN, BASECAT, KEYCAT, Clanker launches, Virtuals agent tokens. ETH in the Crypto tab at 0.05%.
- BalanceThe same USD balance as Solana, BNB Chain, Monad, Ethereum and Robinhood Chain. Nothing to bridge.
- Fee0.5% per trade, about $0.95 minimum, gas included. 0.45% with referral code GEMQUEENX.
- GasPaid by Fomo. On Base a transfer costs a cent or two and a swap five to twenty cents, which the 0.5% absorbs.

What is Fomo Base?
Fomo Base is Base support inside the Fomo app: you buy and sell any token on Coinbase's Layer 2, from BRETT and TOSHI to the day's Clanker launches, out of the same USD balance you use on Solana, with the ETH gas paid by Fomo and a 0.5% fee.
What Base is for, inside Fomo
Base is Coinbase's own Layer 2, built on the OP Stack and settling to Ethereum, and it behaves like a cheap Ethereum rather than a fast Solana. Blocks land every two seconds, with sub-second preconfirmations since the Flashblocks upgrade, and gas costs pennies. By May 2026 more than $13 billion had been bridged onto it. Fomo added it in September 2025, the month it stopped being a Solana-only app.
The crowd is what makes it different. Base memecoins come out of Coinbase users and the Farcaster social graph rather than the Solana launch machine, so the names last longer and move slower: BRETT and TOSHI have been around for years and still sit at the top of the category. The whole category is worth about a tenth of Solana's, which is the trade you make here. Fewer rugs per hour, and fewer ten-baggers too.
What can you trade on Base with Fomo?
Anything with a pool on Uniswap or Aerodrome, which on Base means four fairly distinct groups. Fomo shows the chain badge, the verified contract and the expected price impact on every one of them.
| Group | Examples | Fomo fee | Notes |
|---|---|---|---|
| Established memecoins | TOSHI, BRETT, DEGEN, BALD, KEYCAT | 0.5% | The survivors; TOSHI and BRETT both around $52M in September 2026 |
| Newer memecoins | BASECAT, DRB, STONKEX, BLUECHIP | 0.5% | Where the volume concentrates on a given week |
| Clanker launches | Whatever was deployed from a prompt today | 0.5% | More than 500,000 tokens launched since November 2024; almost all are empty |
| AI agent and app tokens | VIRTUAL and its agent tokens, ZORA, AERO | 0.5% | Deeper pools, driven by the product rather than a meme |
ETH itself sits in the Crypto tab at 0.05%. The Base leaderboard ranks the chain's top tokens by gains, volume and holders, and the feed shows which of the traders you follow are in them.
How to buy Base memecoins on Fomo
Install Fomo and sign up 10% off
Get the app from the App Store or Google Play, or open fomo.family. Sign up with email, Apple or Google and type referral code
GEMQUEENXon the sign-up screen. The wallet it creates already works on Base.Deposit once
Apple Pay, Google Pay, a card, or USDC from an exchange. One balance covers all six chains, so money that arrived for a Solana trade buys BRETT without a bridge.
Find the token Pool size first
Search the ticker, open it from the feed, or browse the Base leaderboard. Match the Base badge and the verified contract, then read the pool size. Base carries hundreds of thousands of Clanker tokens with a name and no liquidity behind it.
Buy in one tap About 2 s
Pick an amount and confirm. Fomo pays the ETH gas and charges 0.5%. Above about $200 the fee is a flat rate; below that the $0.95 minimum takes over, the same as on every chain.
Sell from the position screen
Sell a percentage or all of it. Watch the price impact: a Base token at $10 million often has a thinner pool than a Solana token at the same market cap, so large sells land worse than the chart suggests.
What a Base trade costs on Fomo
Fomo charges 0.5% of the trade, or 0.45% with referral code GEMQUEENX, with a minimum of about $0.95, and pays the ETH gas on Base. Doing it yourself means a wallet with Base added, ETH bridged over for gas, a token approval and a swap on Uniswap or Aerodrome, each with its own fee. Base gas is cheap enough that the by-hand route is not expensive; it is just four steps and a bridge instead of one tap.
| $500 buy on Base | Fomo | Wallet plus a DEX |
|---|---|---|
| Trading fee | $2.50, or $2.25 with the code | Pool fee, typically 0.3% to 1% |
| Gas | $0, paid by Fomo | A few cents per step, in ETH you must hold |
| Bridging | None | Needed unless funds are already on Base |
| Steps | One tap | Bridge, approve, swap |
| Other chains | Same balance on six | Per chain, per wallet |
The full schedule, including the $0.95 floor that makes small buys expensive, is on the fees page. The fee is identical on Solana and Ethereum, so on Fomo the chain is a choice about tokens and speed, never about price.
Filter the feed to Base only
Since August 18, 2026 the feed can be cut to a single chain. Set it to Base and every row is a token you can buy from the balance you hold, the Solana launches stop scrolling past, and what is left is the slower Base rhythm: the Clanker deploys, the Virtuals agents, the old names moving on Coinbase flow.
It works best next to the size and thesis filters added on August 20. A Base-only feed of trades above $500 that carry a written reason is short, and short is what stops a feed from turning into a slot machine.
Where Base trades go wrong
Coinbase runs the chain. Nobody runs the tokens on it, and Base has its own failure modes.
Half a million empty tokens
Clanker will deploy a token from a sentence, and most of the ones it has deployed have no pool worth trading. A name that matches a trend means nothing here. Check the liquidity, then the chart.
Thin pools under big numbers
Base market caps look like Solana market caps and are backed by less. A $10 million Base token can have a few hundred thousand dollars in its pool, which is fine going in and painful coming out.
Sell taxes in the contract
Base is EVM, so a token can charge on the sell or block it outright, which Solana tokens mostly cannot. It shows up as a price impact that makes no sense for the pool size. Believe that number.
A quieter chain cuts both ways
Fewer rugs per hour also means fewer buyers when you want out. Base moves on Coinbase and Farcaster attention, and when that attention is elsewhere the volume simply is not there.
Base on iPhone, Android and Fomo Web
Base is on wherever the account is. The iPhone and Android apps carry the feed, the push alerts and Apple Pay or Google Pay deposits. On Fomo Web at fomo.family the same tokens open on a TradingView chart with the entries of the traders you follow marked on it. Base trades appear in the copy trading feed like every other chain, and the Base leaderboard holds the current names.
Fomo Base questions
Does the Fomo app support Base?
Yes. Base was the second chain in the app after Solana, with full support from September 2025. You trade any Base token with a pool from the same USD balance as your Solana positions, Fomo pays the gas, and the fee is 0.5%, or 0.45% with referral code GEMQUEENX.
Do I need ETH on Base to trade with Fomo?
No. Base charges gas in ETH, usually a cent or two per transfer and five to twenty cents on a swap, and Fomo pays it out of the 0.5% fee. You never bridge ETH to Base, never top up a gas balance and never see a swap fail because the gas was short.
What can I buy on Base in the Fomo app?
Any Base token with a Uniswap or Aerodrome pool. That covers the older memecoins such as TOSHI, BRETT, DEGEN and KEYCAT, the newer ones like BASECAT, the AI agent tokens from Virtuals, and the Clanker launches that appear on the chain all day. ETH sits in the Crypto tab at the blue-chip rate of 0.05%.
What are Clanker tokens?
Clanker is a token launcher on Base that deploys an ERC-20 from a text prompt. It went live in November 2024, has launched more than half a million tokens since, and was bought by Farcaster. Most of those tokens have almost no liquidity, so they appear in Fomo like any other Base token and need the same check: pool size before market cap.
Is Base cheaper than Ethereum on Fomo?
The Fomo fee is identical, 0.5% on both, because Fomo absorbs the gas either way. What differs is speed and depth. Base confirms in about two seconds against twelve on mainnet, and its memecoin pools are smaller, so a large sell moves the price more on Base than it would on an equivalent Ethereum token.
How big is the Base memecoin market?
Small next to Solana. CoinGecko put the Base memecoin category at about $346 million in early September 2026 on roughly $45 million of daily volume, against $3.8 billion and a billion a day on Solana. Base is where the Coinbase crowd and the Farcaster crowd trade, not where the largest flows are.
Is Base run by Coinbase?
Yes. Base is Coinbase's Layer 2, built on the OP Stack and settling to Ethereum, with a single Coinbase-operated sequencer. It held more than $13 billion in bridged value by May 2026. Coinbase running the chain does not make the tokens on it safe: anyone can deploy, and most Base memecoins are as disposable as any other chain's.
