Getting Started with PulseX
Prerequisites
Before using PulseX, you need:
- MetaMask wallet with PulseChain network added (setup guide)
- PLS for gas — Even tiny amounts work due to low fees
- Tokens to trade — Bridge from Ethereum if needed (bridge guide)
Step 1: Connect Your Wallet
- Go to app.pulsex.com
- Click "Connect Wallet" in the top right
- Select MetaMask
- Approve the connection in MetaMask
- Make sure you're on PulseChain network
⚠️ Security Warning
Always verify you're on the official PulseX website (app.pulsex.com). Bookmark it to avoid phishing sites. Never enter your seed phrase anywhere except your wallet.
How to Swap Tokens on PulseX
Step-by-Step Swap Guide
- Select "Swap" from the menu (default view)
- Choose your input token — Click the top token selector
- Search by name or paste contract address
- Common tokens: PLS, PLSX, pHEX, eETH, DAI
- Choose your output token — Click the bottom token selector
- Enter the amount to swap
- Or click "Max" to swap your full balance
- Review the details:
- Exchange rate
- Price impact (should be <1% for liquid pairs)
- Minimum received
- Click "Swap"
- Confirm in MetaMask
- Wait for confirmation (~10-30 seconds)
First-Time Token Approval
The first time you swap a new token, you'll need to "approve" it. This is a one-time transaction that allows PulseX to spend that token from your wallet.
- Click "Approve [TOKEN]"
- Confirm in MetaMask (small gas fee)
- Wait for approval to confirm
- Now click "Swap" to complete
💡 Pro Tip: Token Approvals
By default, PulseX requests unlimited approval. For better security, you can set a specific approval amount in MetaMask's "Edit Permission" when approving. Learn more in our token approval guide.
Understanding Slippage
Slippage is the difference between expected price and execution price. Set your slippage tolerance in settings:
- 0.1-0.5%: For stable/liquid pairs
- 1-3%: For most tokens
- 5-10%+: For volatile/illiquid tokens
If your transaction fails with "insufficient output," increase slippage tolerance.
Trading Tips for PulseX
1. Check Price Impact
Price impact shows how much your trade moves the market price. High impact (>2%) means you're getting a worse rate. Solutions:
- Split into smaller trades
- Wait for more liquidity
- Try a different route/pair
2. Use Price Oracles
Before large swaps, check prices on:
- PulseScan for token info
- DEX Screener for charts
- Multiple DEXs for comparison
3. Trade Liquid Pairs
Stick to pairs with deep liquidity for best rates:
- PLS/PLSX
- PLS/pHEX
- PLS/eETH (bridged ETH)
- PLS/DAI
4. Time Your Trades
While PulseChain gas is always cheap, trading during:
- Low volatility: Better for limit-like orders
- High activity: More arbitrage, tighter spreads
Providing Liquidity on PulseX
What Is Liquidity Provision?
When you provide liquidity, you deposit two tokens into a pool. Traders swap against your liquidity, and you earn a share of the 0.29% trading fee.
How to Add Liquidity
- Go to "Pool" → "Add Liquidity"
- Select two tokens for your pair
- Enter the amount for one token (other auto-calculates)
- Approve both tokens if needed
- Click "Supply"
- Confirm in MetaMask
- Receive LP tokens representing your share
Liquidity Risks: Impermanent Loss
Impermanent Loss (IL) occurs when token prices change relative to when you deposited. The more prices diverge, the more IL you experience.
⚠️ IL Example
If you provide PLS/PLSX liquidity and PLS doubles while PLSX stays flat, you'd have been better off just holding. You'll have more PLSX and less PLS than you started with.
IL is "impermanent" because if prices return to original levels, the loss disappears. However, if you withdraw while prices diverge, the loss becomes permanent.
When LP Is Profitable
- Trading fees exceed impermanent loss
- Pair stays relatively stable
- High trading volume on the pair
- Long-term LP during sideways markets
How to Remove Liquidity
- Go to "Pool"
- Find your position
- Click "Remove"
- Select percentage to remove (25%, 50%, 75%, 100%)
- Click "Remove"
- Confirm in MetaMask
- Receive your tokens back
PLSX Token
What Is PLSX?
PLSX is PulseX's native token. It was distributed during the sacrifice phase and is used for:
- Governance: Voting on protocol changes (planned)
- Fee Sharing: PLSX stakers earn protocol revenue (planned)
- Trading: One of the most liquid pairs on PulseX
How to Buy PLSX
- Get PLS or bridged tokens on PulseChain
- Go to PulseX swap
- Swap PLS → PLSX
Advanced PulseX Features
Multi-Hop Swaps
PulseX automatically routes through multiple pools to find the best price. For example: Token A → PLS → Token B might be cheaper than a direct A → B swap.
Price Charts
PulseX shows basic price charts. For advanced charting, use:
- DEX Screener (dexscreener.com/pulsechain)
- Dextools
- GeckoTerminal
Token Lists
PulseX uses token lists to show verified tokens. Unlisted tokens can still be traded by pasting the contract address, but be extra careful — anyone can create a token.
Troubleshooting Common Issues
"Insufficient Liquidity"
- Trade a smaller amount
- Try a different route (swap to PLS first, then to target)
- Wait for more liquidity
"Transaction Failed"
- Increase slippage tolerance
- Check you have enough PLS for gas
- Make sure token approval completed
- Try again (network might have been busy)
"Price Impact Too High"
- Split into multiple smaller swaps
- Use a different token pair with more liquidity
- Wait for better liquidity conditions
Can't Find a Token
- Paste the contract address directly
- Verify address on PulseScan first
- Be careful with unlisted tokens — verify legitimacy

Frequently Asked Questions
Is PulseX safe?
PulseX uses battle-tested Uniswap V2 code and has been running since PulseChain launch without security incidents. However, always use good security practices and only trade what you can afford to lose.
What are PulseX fees?
PulseX charges 0.29% per swap (goes to liquidity providers). Gas fees on PulseChain are ~$0.001-0.003 per swap — negligible compared to the trading fee.
Can I trade ETH on PulseX?
Not directly. You need to bridge ETH to PulseChain first (it becomes eETH), then trade on PulseX. Use our bridge guide.
How do I add a custom token to PulseX?
Paste the token's contract address into the token search box. PulseX will find it. Always verify contract addresses on PulseScan before trading.
Why is my swap taking so long?
Swaps usually confirm in 10-30 seconds. If stuck, check PulseScan for your transaction. You might need to increase gas price or your transaction might have failed.
Conclusion
PulseX is the gateway to DeFi on PulseChain. With ultra-low fees, deep liquidity, and a familiar interface, it's perfect for both beginners and advanced traders. Start small, learn the platform, and gradually explore liquidity provision once you're comfortable.
