How to Find a Token's Real Contract Address
The quickest reliable way is to look the coin up on Lasso or CoinGecko and copy the address listed for the network you're buying on. Then check that the same address appears on the project's official website or official X account. Two trusted sources that agree are enough. A token's name and ticker prove nothing, because anyone can launch a token called "PEPE" in a minute, and dozens of copies of popular coins exist on every network.
Quick answer
Copy the address from Lasso or CoinGecko, confirm it on the project's own site, then check that the first and last few characters match in your swap app before you confirm.
What a contract address looks like
- Ethereum, Base, Arbitrum, BNB Smart Chain: 42 characters starting with 0x, like
0x6982508145454Ce325dDbE47a25d4ec3d2311933(PEPE on Ethereum). - Solana: 32 to 44 letters and numbers with no prefix. On Solana it's often called the mint address.
The same coin can have a different address on each network. USDC on Base and USDC on Ethereum are different contracts, so always match the address to the network you're on.
Step-by-step
- Look the coin up on LassoSearch the coin on Lasso and open it. The buying guide shows the contract address for each network the coin lives on, with a copy button.
- Cross-check with a second sourceCompare it with the Contract section on CoinGecko's page for the coin, or the project's official website. Reach the site by its known address, not through a search ad.
- Check it on a block explorerPaste the address into Etherscan, Basescan or Solscan. The real token usually has a long history, many holders and a name that matches. A copy is often days old with few holders.
- Compare inside the swap appWhen you paste the address into Jupiter or Uniswap, check that the first and last 4 to 6 characters on the confirm screen match what you verified.

Red flags
- An address sent to you in a DM, Telegram group or reply, even from an account that looks official
- A token "launched today" that claims to be a famous coin
- A token that appeared in your wallet uninvited
- A swap app warning that the token is unverified or not on its token list
If two trusted sources disagree, stop. Don't buy until you know which address is real.
What to do next
Once you have the right address, the route to buy depends on the network. See how to buy crypto not listed on Coinbase, or read how to spot a scam token for more checks before you buy.
