Before you start
- A wallet on Base. See Your first crypto wallet.
- Some ETH on Base. See How to get ETH on Base.
- The token's contract address from its official website or socials.
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.
