The cat of Ethereum.

ETHCAT is the cat that sits on the ethereum.org homepage, adopted by the people who live on-chain. No roadmap, no utility deck, no promises — just the cat and the culture around it.

If there was no Ethereum, there wouldn't be CATSZN. claim 1 of 5

An ethereum.org-style illustration of a foundation event: a white cat sits beneath the Ethereum diamond, with a speech bubble pointing at it reading "The cat of ethereum.org foundation".

One ecosystem

Many cats.

Ethereum gave the internet a place where cats can exist, multiply and turn into culture. Every cat coin you hold is downstream of the same chain.

🐱

CATSZN

If there was no Ethereum, there would be no CATSZN right now.

💜

Cashcat

Another cat-shaped piece of Ethereum culture — built on Robinhood Chain, itself an Ethereum layer 2.

⛓️

Basecat

Basecat runs on Base. Base is a rollup. Rollups settle to Ethereum. You can see where this is going.

Anything else

Pick any cat on any chain. Follow it down far enough and you land on the same block.

The source

What Vitalik said.

The cat narrative didn't come from a marketing call. It came from a Farcaster post.

我没有自己的狗狗呢…… 我的家人也没有,只有猫

“I don't have a dog of my own… My family doesn't either, only cats.”

Vitalik's Farcaster post, in Chinese, saying he has no dog of his own and neither does his family — only cats. 3 reposts, 30 likes.

How to buy

Three steps to the cat.

ETHCAT is a standard ERC-20 on Ethereum mainnet. If you've swapped a token before, you already know how this goes.

STEP 01

Get a wallet

Install any Ethereum wallet — MetaMask, Rabby, Coinbase Wallet, Rainbow. Write the seed phrase down on paper and never type it into a website.

STEP 02

Fund it with ETH

Send ETH to your wallet on Ethereum mainnet. You'll need a little extra to cover gas on top of whatever you're swapping.

STEP 03

Swap using the contract

Paste the contract address into Uniswap or any aggregator, check it matches the one on this page character for character, set your slippage and swap. Then watch the chart.

FAQ

Questions people actually ask.

What chain is $ETHCAT on?
Ethereum mainnet. It's a plain ERC-20, tradeable on any Ethereum DEX or aggregator using the contract address above.
Is ETHCAT connected to the Ethereum Foundation?
No. ETHCAT is a community meme built around the cat that appears in ethereum.org's artwork. There is no affiliation with, endorsement by or involvement from the Ethereum Foundation or Vitalik.
Is there a buy or sell tax?
Check the contract on a block explorer or a token scanner before you buy — don't take any website's word for it, including this one.
Where do I check the price?
DexScreener, linked at the top and bottom of this page. The numbers in the hero strip are pulled live from the same source.
How do I avoid buying a fake?
Only ever use the contract address shown on this site or in the pinned messages of the official X and Telegram accounts, and compare it character by character. Fake cats are a genre.
Is any of this financial advice?
No. $ETHCAT has no intrinsic value and no expected return. It exists for entertainment and community. Only spend what you'd be fine losing entirely.
