How to buy a token on Base

Buying a token on Base is called a swap: you trade ETH for the token you want. Once your wallet has a little ETH on Base, it takes under a minute.

Before you start

Step 1: check the contract address

Anyone can create a token with any name, so many tokens share the same name. The contract address is the only thing that identifies the real one. Copy it from the project's official website, then compare it on BaseScan. For example, the official Jerry on Base contract is 0x249ad52cBdC813F789AaF52aD6a1647376C33D6D.

Step 2: open a swap

Use a trusted swap like Uniswap, or a swap built into the project's own site. On jerryberry.meme, the Trade page swaps through Uniswap on Base.

Step 3: choose the amount

Enter how much ETH you want to spend. Leave a little ETH in your wallet for future fees.

Step 4: check slippage

Slippage is how much the price is allowed to move while your swap goes through. A small amount like 1 to 3 percent is normal. Very high slippage can lose you money, so only raise it if a swap keeps failing and you understand why.

Step 5: confirm in your wallet

Your wallet shows what you are about to do and the fee. Read it, then confirm. The swap usually finishes in a few seconds on Base.

Step 6: see it in your wallet

Some wallets need you to add a new token before they show it. On Jerry's site you can do it in one click with Add to wallet next to the contract address.

Avoid these mistakes

  • Buying a token with the right name but the wrong contract.
  • Clicking swap links from DMs or random replies.
  • Spending money you cannot afford to lose. Meme coins are for fun and can go to zero.
FAQBuying questions

Buying on Base, answered

Why did my swap fail?

Common reasons are not enough ETH for the fee, slippage set too low for a fast-moving price, or a token with transfer limits. Some tokens only allow one trade per wallet every few seconds, so waiting a moment and trying again can help.

How do I sell a token on Base?

The same way in reverse: swap the token back to ETH. On jerryberry.meme the Trade page has a Sell tab.

How do I know a token is real?

Only the contract address proves it. Get it from the official website, and never from a DM or an ad.
