How to check a memecoin before buying

How to check a memecoin before buying: start with the contract address

Two tokens can carry the same name and the same ticker, so the address is the only thing that points at one contract. Find the token on a pair screener, copy the address of the pair you are actually looking at, and paste it into the tools yourself instead of clicking a link someone sent you.

Then open that address on the chain's explorer (Solscan, Etherscan, Basescan, BscScan). It is not a safety check, but it is the cheapest way to confirm that the address you scanned is the address you are about to buy.

1. Find the token on a pair screener and copy its contract address, never the ticker.
2. Paste the address into the scanner yourself: a link from a group chat can point at a different contract.
3. Open the same address on the chain's explorer (Solscan, Etherscan, Basescan, BscScan).
4. Look at how the pair is funded: a thin pair is where memecoins fail first.

Run the rug check: authorities, liquidity, holders, snipers

On Solana, paste the mint into RugCheck and read four things: whether the mint and freeze authorities are still active, how much of the LP is locked, how concentrated the holders are, and what the insiders view and the token networks graph show. The report returns a 0-100 risk score written as “Rugcheck risk 42/100 (lower is safer)”, the direction people get wrong.

Rug.Tools runs the same mint through nine documented steps, up to creator launch history, bundle detection and wallet relationships, and ends in one of five verdicts. On Ethereum, BSC or Base, Honeypot.is buys and sells the token for you and reports the buy, sell and transfer taxes, the gas, the honeypot reason and the pair's liquidity. Token Sniffer turns owner privileges, modifiable fees and liquidity locks into a 0-100 score, and GoPlus returns raw flags such as is_honeypot and is_mintable across 46 chains.

1. Solana: RugCheck for the risk score, the LP locked share, holder concentration and the insiders view.
2. Solana: Rug.Tools for the creator's launch history, bundle detection and wallet relationships.
3. EVM: Honeypot.is for a real buy and sell simulation, with the taxes and the honeypot reason.
4. EVM: Token Sniffer for a 0-100 score, or GoPlus for the raw flags.

Read the wallet clusters with Bubblemaps

A rug check tells you whether a contract is armed. Bubblemaps answers the other half: who holds this, and are they the same people? Wallet clusters and Magic Nodes expose links a holder list hides, Time Travel and real-time distribution show how the supply moved, and the Bubblemaps Score rates how decentralised the supply is. V2 is free, with a swap built into the map.

It says nothing about mint authority, taxes or honeypots, and P&L, cross-chain analytics, AI clusters and maps of the top 1,000 holders need $BMT. Its own HAWK case study walks through insiders dumping 16% of the supply, the pattern the cluster view exists to expose. Read it as the supply side of the check, never as the whole check.

See who is buying before you buy

A tracker covers the minutes a scanner cannot: who is accumulating the token right now. SpyBot, our editor's pick among wallet trackers, alerts on swaps, transfers, token launches and Meteora liquidity, with more than 50 filters per wallet — trade size, market cap, token age, first buy only — plus coordinated-buy detection across the wallets you follow, PnL per wallet and a Top Traders directory of KOLs, whales and high-ROI wallets.

The free plan covers 25 Solana and 10 EVM wallets with 1,000 alerts a day, and paid plans start at 0.05 SOL a month for up to 1,000 Solana and 500 EVM wallets, a year costing the price of five months. Ethereum, Base, BSC and Robinhood Chain wallets land in the same feed, and one-tap Solana buys are routed through Jupiter at 1% per trade from an optional non-custodial wallet whose key you can export. Treat coordinated buys as a warning rather than a signal, and read a wallet's PnL before following it.

How to spot a rug pull: the signals the reports make visible

The classic rug pulls leave traces these tools are built to surface. Rug.Tools detects bundles, meaning wallets funded or buying together, and GoPlus as well as Token Sniffer flag the owner privileges and modifiable fees a creator can change after you buy. Wallet clusters: Solsniffer groups into tagged clusters the wallets that transfer funds back and forth with a top holder, and Token Sniffer counts a holder passing 5% of supply among its score drivers.

RugCheck returns the locked share of the LP, and Token Sniffer's score falls when a lock expires. On the contract side, RugCheck reports whether the mint and freeze authorities are still active, GoPlus returns is_honeypot, is_mintable, blacklist, proxy and selfdestruct, and Honeypot.is reports the honeypot reason and the proxy flags. None of these signals is proof on its own; several together is the pattern to walk away from.

Solana and EVM do not fail in the same way

On EVM chains the classic trap is the honeypot: the contract accepts your buy and blocks the sell, often with a tax that makes selling pointless. That is why Honeypot.is executes both legs and returns the buy, sell and transfer taxes with the honeypot reason, and why GoPlus returns is_honeypot and is_mintable as separate fields. Two of the EVM tools here are also the narrowest: Honeypot.is covers Ethereum, BSC and Base only, and De.Fi is EVM-only, with no Solana coverage in its scanner or its API.

On Solana the same failure looks different: the checks these tools document are the mint and freeze authorities, the LP locked share, holder concentration, insiders, bundle detection and wallet clusters rather than a buy and sell simulation. RugCheck stops at Solana and Fogo, Solsniffer is Solana-only, and Token Sniffer is the only tool in our set that documents both EVM chains and Solana from one score.

Test small, set your exit, and know what a score does not cover

No tool here guarantees a token is safe, and two say so themselves: Token Sniffer's FAQ warns that a perfect 100/100 score can fall by up to 20 points within two weeks, and Honeypot.is warns that a clean result today does not guarantee it stays clean. RugCheck's verified badge comes from token management, so it is not an audit, Solsniffer does not publish its indicator list, and Rug.Tools is young enough that its market health page withholds the validated score.

So finish the method the way you started it: with a decision you control. Buy a small amount you are willing to lose, sell part of it early, and set your exit before you buy. Then buy with a bot, knowing the cost: GMGN's documentation recommends 30-50% slippage on memecoins, platform fees are charged per trade, 1% standard against 2% on copyfomo, and SpyBot's one-tap buys cost 1% per trade, so a round trip pays twice.

1. Test with an amount small enough that a bad outcome does not change your week.
2. Sell part of it early to see how the token behaves when you exit.
3. Set your exit before you buy, not after.
4. Write the round trip down: platform fee in, platform fee out, gas, priority fee, slippage.
5. Then buy with a bot, and keep the scanner result next to the position rather than in place of it.
