What do I actually need to have ready before I can swap one coin for another

07 September 2026

You need a funded wallet, a supported browser, and a clear idea of which token you want to swap into which other token. That is the short answer. The longer answer is that each of those three things has a few details you should check before you start.

A funded wallet. This is the most important item. You cannot swap anything if you hold nothing. The wallet must contain the token you intend to spend, plus a small amount of the network's native coin to pay transaction fees. For example, if you are swapping a Solana-based token, your wallet needs some SOL in it - not much, but some. The fee is not taken from the token you are spending; it is taken from your balance of the chain's native currency. If your wallet has the trade token but zero native coin, the swap will fail. Check this before you click anything.

Which wallet? Most people use a browser extension wallet. MetaMask is common for Ethereum-based chains; Phantom or Solflare are common for Solana. You need the extension installed and unlocked. If you are using a mobile device, you will need the wallet app and probably a built-in browser inside that app. Desktop is simpler for a first swap. The wallet must be connected to the site you are using. That connection is not automatic - you have to approve it, usually by clicking a "Connect Wallet" button and then confirming in the extension.

The tokens themselves. You need to know exactly which token you are sending and which token you want to receive. Tokens have names, tickers, and contract addresses. The contract address is what actually identifies the token on the blockchain. A name like "PEPE" can refer to many different tokens on different chains. The same ticker can be a scam copy. Do not rely on the name alone. If you are swapping on a site like pumpfun, the site will show you the token's contract address. You can verify it against the official source - often the project's website or a block explorer. If the address does not match, do not proceed.

A supported browser. Most swap sites work best in Chrome, Brave, or Firefox. Some also support Edge. Safari has a history of wallet connection issues. Make sure your browser is up to date. Outdated browsers can break the wallet extension or the site's interface. Also disable any ad blocker for the swap site. Some ad blockers interfere with wallet popups.

Gas fees and slippage. You do not need to calculate these in advance, but you need to understand they exist. Gas is the fee paid to the network. Slippage is the price change that happens between when you submit the swap and when it executes. The site will show you both. You can adjust slippage, but for a first swap, leave it at the default 0.5% or 1%. Setting it too low can cause the swap to fail; setting it too high can cost you more than expected.

A clear goal. Know what you are trying to do. Are you swapping into a token to hold it, or to sell it immediately? If you are swapping into a token on pumpfun, the process is the same as any other swap - connect, select, confirm - but the token may have different liquidity or price behaviour. The hub page titled "How to swap your first token on pumpfun" covers that exact flow step by step. Read it after you have your wallet ready.

One more thing: don't rush. Swaps are irreversible. If you send to the wrong contract address, you cannot undo it. If you approve a malicious contract, your wallet can be drained. Take the time to verify every address. If anything feels off, stop and check again.

That is the full list. Wallet with funds and native coin. Browser with extension installed. Correct token addresses. Slippage left at default. A clear swap goal. Everything else - clicking buttons, confirming in the wallet - the site will guide you through.
