How to Buy a Pump.fun Token

What is Pump.fun

Pump.fun is a Solana launchpad that lets anyone create a memecoin in seconds. The platform uses a bonding curve to bootstrap liquidity — as more people buy the token, the price rises along a predictable curve. Once the token reaches a market cap threshold, the liquidity migrates to a traditional AMM (usually Raydium) and the token becomes freely tradable.

Because anyone can launch a token on Pump.fun in under a minute, the vast majority of tokens are scams, jokes, or abandoned within hours. A small fraction achieve meaningful volume and lasting communities. This guide explains how to buy them safely through KingSwap without falling for the most common traps.

Step 1 — Find a token you want to buy

Open Pump.fun in a browser tab and browse the live feed or the "about to graduate" section. Alternatively, use DEX screeners like DexScreener or Birdeye to find freshly launched Solana tokens with active volume. Once you have identified a token, copy its mint address — the long string starting with letters and numbers, not the token name.

Step 2 — Verify the mint on Solscan

Paste the mint address into Solscan and check four things: liquidity size (should be at least $10,000), holder count (more than 100 is a good sign), freeze authority (should be disabled — otherwise the creator can freeze your tokens), and mint authority (should be disabled — otherwise the creator can mint infinite new supply).

Step 3 — Connect your wallet to KingSwap

Go to KingSwap and click Connect Wallet. Approve the connection in Phantom, Solflare, or Backpack. Make sure your wallet has at least 0.01 SOL for gas fees plus the amount you want to swap.

Step 4 — Paste the mint address

Click the token selector in the "You receive" field, then click PASTE MINT. Paste the mint address and confirm. KingSwap will load the token and show its live price. If the token does not appear, it may not have migrated to a DEX yet — wait for it to graduate from Pump.fun.

Step 5 — Set high slippage

Fresh tokens move fast. Use 5% slippage for tokens that have already migrated to a DEX, 10-20% for tokens still on the Pump.fun bonding curve. Higher slippage increases the chance of execution but exposes you to worse fills. Only use what is necessary.

Step 6 — Swap a small test amount first

Before committing your full position, swap a tiny amount — $5 or less — to confirm the token is not a honeypot. A honeypot lets you buy but blocks selling. Once you have confirmed you can sell your test amount back, scale up. This single step prevents most losses.

Common red flags

Freeze authority enabled. The creator can freeze your wallet and prevent you from selling.
Mint authority enabled. The creator can mint unlimited new tokens and dilute your holdings.
Liquidity below $5,000. Easy for the creator to pull in a rug.
Fewer than 50 holders. Likely a fresh scam with no real community.
Top 10 holders own more than 50%. High concentration increases dump risk.

Why use KingSwap instead of Pump.fun directly

Pump.fun only lets you buy on the bonding curve. Once a token graduates to a DEX, you need an aggregator to find the best liquidity. KingSwap routes through all Solana DEXs — including PumpSwap, Raydium, and Meteora — so you get the best rate whether the token just launched or graduated. You also get slippage control, live price updates, and USD value display, none of which Pump.fun provides.
