Optimism token scanner: rug pull and honeypot check
Paste a Optimism token contract to check it before you buy: honeypot, buy and sell tax, mint, ownership, liquidity lock and holder concentration, in a few seconds.

The scan reads the contract and its holders on Optimism through GoPlus Security. It flags known risks; it does not prove a token is safe.
How to check if a new meme coin is a rug pull
Paste the contract address in a free scanner and look at five things: can you sell (honeypot), the sell tax, whether new tokens can still be minted or wallets frozen, how much of the pool liquidity is locked or burned, and how much of the supply the top 10 wallets hold. A token that fails one of the first three is a no. A clean result only filters out the most common traps: it is not an audit.
- Copy the contract address from the project's own website, X account or its DEX Screener / pump.fun page, never from a DM or a reply.
- Paste it above and pick the chain. Solana, Ethereum, BNB Chain, Base and other EVM chains are supported; Solana and Tron addresses are recognised automatically.
- Stop at once if holders cannot sell (honeypot), the sell tax is above 15%, or the mint or freeze authority is still active.
- Check the liquidity: under 90% locked or burned means part of the pool can be pulled in one transaction, under 50% is a high risk.
- Check the holders: when the top 10 wallets hold 30% or more of the supply (pools and burns excluded), a few sellers can crash the price. Look for wallets funded by the developer.
- Then check what a contract cannot show: how old the token is, whether the team and links are real, and whether trading and votes look organic.
What the scanner checks
| Check | What it means | Red flag |
|---|---|---|
| Honeypot | A honeypot lets you buy but blocks or taxes every sell. The scanner simulates the rules of the contract to see if a sell would go through. | The sell simulation fails or is blocked: do not buy. |
| Buy / sell tax | Buy and sell taxes are taken on every trade. Up to 5% is common; above 15% most of your money goes to the contract. | Sell tax above 15% (5-15% = caution), or a tax the owner can still change. |
| Mint function | A mint function lets the owner create new tokens at any time, which dilutes every holder. | Mint function active (EVM) or mint authority not revoked (Solana). |
| Ownership | While the owner keeps control, they may change fees or limits. Renounced ownership removes that power, a hidden owner or a reclaim function brings it back. | Owner not renounced on a small token, a hidden owner, or ownership that can be taken back. |
| Upgradeable proxy | A proxy contract can be swapped for new code after launch. Common for large projects, a risk on small ones. | Upgradeable proxy on a small or anonymous project: the code can change after you buy. |
| Liquidity locked or burned | Share of the DEX liquidity that is locked or burned. Unlocked liquidity can be pulled out at once: the classic rug pull. | Less than 90% of the DEX liquidity locked or burned; under 50% is a high risk. |
| Top 10 holders | Share of the supply held by the ten largest wallets, without burned, locked and pool addresses. A high share means a few wallets can crash the price. | Top 10 wallets hold 30% or more of the supply; 60% or more is a high risk. |
| Solana | On Solana, the scanner checks the mint and freeze authorities, transfer fees and whether the token metadata can still be changed. | Freeze authority not revoked (your tokens can be frozen) or metadata that can still be changed. |

What the scanner checks and does not check
For supported chains, the scanner displays available GoPlus token-security data, including sell restrictions, taxes, minting, ownership, proxy status, liquidity and holder concentration where provided. Available checks differ by chain.
This is not a smart-contract audit or a guarantee of safety. Data can be missing, delayed or inaccurate, and contract behaviour may change. The scanner does not verify the project team, future prices or every possible risk.
Questions
Is a token safe if the scan shows no red flag?
No. The scan reads the contract code and on-chain data. A clean contract can still belong to a team that dumps its own wallets, fakes volume or disappears. Use it as a first filter.
Where does the data come from?
From the GoPlus Security API, used by many wallets and DEX tools. Results are kept for about 12 hours, then refreshed on the next scan.
Why is my token not found?
The scanner only knows tokens that have a trading pool on a supported DEX. Very new tokens can take a few hours to appear.
Does it cost anything?
No. The scanner is free and needs no account or wallet connection. Never sign a transaction to "verify" a token.
How can I tell if a Solana meme coin is a rug pull?
Check that the mint and freeze authorities are revoked, that most of the pool liquidity is locked or burned and that the top 10 wallets hold well under 30% of the supply. Then look at the developer wallet: early sells by the developer, or many holder wallets funded from the same address, are the most common signs before a rug.
What does locked liquidity mean?
The LP tokens that represent the trading pool are sent to a time-lock contract or burned, so the team cannot withdraw the pool. Unlocked liquidity can be removed in one transaction, which takes the price close to zero: the classic rug pull.
Which blockchains does the scanner support?
Currently: BNB Chain, Ethereum, Solana, Base, TRON, Arbitrum, Polygon, Avalanche C-Chain, Optimism, Blast, Abstract, KCC, Robinhood Chain, Monad, Sonic, Unichain, Berachain. Available checks differ by chain: Solana tokens are checked for mint and freeze authority, transfer fees and mutable metadata instead of EVM owner functions.
