How to Perform DEX Swap Transactions: A Complete Guide

Understanding Swap Transactions

Swap transactions refer to exchanging one cryptocurrency for another within the same blockchain network, where both the payment and received tokens share the same underlying protocol. This is among the most frequently used features in Web3 wallets, accessible via both mobile apps and web platforms.

Preparing for Your Swap

1. Set Up a Web3 Wallet

• Create or import a wallet like OKX Wallet.

2. Fund Your Wallet

• Deposit assets into your wallet to enable swaps.

3. Locate Token Contract Addresses

• Identify the contract address of the token you wish to acquire.

Executing a Swap: Step-by-Step

Example: Buying TRUMP on Solana Network

• Prerequisite: Ensure you hold SOL (Solana's native token) for gas fees.

Mobile App (OKX Wallet)

1. Navigate to DEX > Swap.
2. Select tokens (top = payment, bottom = receipt).
3. Choose Market Order (default) or Limit Order, enter amount, and confirm via wallet.

Web Platform

1. Visit OKX Wallet’s DEX section, select Swap.
2. Pick the network (e.g., Solana), input token pair and amount.
3. Review estimated rate, slippage, and fees before confirming.

Browser Extension

• Log in, select Swap, choose network/tokens, and approve via DEX integration.

Key Considerations

1. Backup: Always secure your wallet’s recovery phrase.
2. Gas Fees: Native tokens auto-deduct gas; insufficient balances cause failures.
3. Network Congestion: High traffic (e.g., Ethereum) may spike gas costs.
4. Slippage: Volatile tokens require higher slippage tolerance.
5. Post-Transaction: Track swaps via wallet history or blockchain explorers.

FAQs

A: Common causes include low gas reserves, excessive slippage, or insufficient liquidity.

Q: How do I adjust slippage tolerance?

A: Settings vary by platform; look for "Advanced Options" during swap setup.

Q: Where can I view past transactions?

A: Check your wallet’s history tab or explore the TX hash on block explorers.
