Axiom, GMGN, pump.fun, fomo: where to trade memecoins

Memecoins trade on launchpad apps such as pump.fun, on trading platforms such as Axiom, on GMGN, which calls itself a multi-chain meme trading terminal, and in mobile wallet apps such as fomo. They differ in custody, supported chains and fees. Axiom describes its wallet as non-custodial, GMGN lists Solana, BSC, Base and Ethereum, and pump.fun publishes a fee schedule last updated on 17 October 2026.

Where can you trade memecoins?

You can trade memecoins on a launchpad app, a trading platform, a multi-chain terminal or a mobile wallet, and the four products below each sit in a different one of those groups.

On pump.fun, a new coin is priced along a bonding curve until it graduates to PumpSwap. GMGN watches new tokens as they appear on Pump.fun, FourMeme, Raydium and letsbonk, and lets you narrow that stream by market cap, volume and creation time. fomo describes itself as a Web3 wallet for trading from one mobile app, and says its social features show what top traders are buying.

What do Axiom, GMGN and pump.fun say about their trading tools?

Each platform describes its tools in its own terms: Axiom stresses onchain funds and trading features, GMGN stresses screening and copy trading, and pump.fun stresses where its fees apply.

Axiom calls itself decentralized and says its funds and transactions are onchain and always in the user's control. Its docs mention buying and selling on migration, spot buys, quick sell, a Twitter monitor, wallet tracking and limit orders.

GMGN lists a longer set of checks and trackers. Its automated audit covers whether liquidity is burned, whether a token is a honeypot, whether the contract is renounced and whether more supply can be minted. It also calculates four holder metrics: insider wallet ratio, bundle buy ratio, developer holdings and top 10 wallet concentration. Its trending leaderboard refreshes every minute, and its copy trading mirrors the buys and sells of wallets it identifies as high-win-rate.

pump.fun frames the matter through fees. Its Platform Fee covers trades placed in its own web app or mobile app, and trades made through another interface skip that fee but may carry the interface's own charges.

What fees do they charge?

pump.fun and Axiom publish their percentages, while GMGN and fomo state no trading fee on the pages they publish for these products. Axiom's fee page sets a net fee of 0.95% at the first tier and 0.75% at the top one, with cashback paid in SOL (as of 28 October 2026). The table covers what pump.fun states on the same date.

Once a coin has graduated, the PumpSwap fee for its canonical pool varies with the coin's market cap. A coin paired with some other asset pays flat rates instead: 1.25% across all fee types on the bonding curve, and 0.30% once it trades in a PumpSwap canonical pool.

The Platform Fee is tied to pump.fun's own apps. On other interfaces it does not apply, but those interfaces set their own charges.

What should you check before connecting a wallet?

The platforms' own documents touch four points that matter before a wallet is connected: custody, contract addresses, the fee shown at confirmation and regional limits.

• Custody. Axiom says its wallet is fully non-custodial and secured by Turnkey's infrastructure. fomo describes its wallet as non-custodial too, with recovery by signing in with an email or Apple ID.
• Contract addresses. pump.fun's supported pair assets page states that a coin sharing a name or symbol with a pair asset but sitting at a different contract address is a different coin.
• Fee display. pump.fun shows its Platform Fee as a separate line before a trade is confirmed.
• Regional limits. pump.fun's perpetuals feature runs through Hyperliquid and is closed to people in the United States and some other jurisdictions.

For fake sites, wallet drainers and signature requests in general, the airdrop scams guide covers the patterns.

What do the platforms warn about?

Each platform's own text says losses are possible. pump.fun's Terms of Use say memecoin values can swing widely and that buying, selling or holding any digital asset on the platform carries a real risk of financial loss. fomo's meme coin explainer says prices can change sharply, liquidity can disappear and buyers can lose the entire amount they invest. The disappearing-liquidity case is the one described in the rug pull entry.
