How to Swap Tokens on MetaMask
Follow these steps to perform a token swap:
| Step | Action | Details |
|------|--------|---------|
| ① | Prepare gas fees | Ensure you hold the native token for gas fees on your target blockchain (e.g., ETH for Ethereum). |
| ② | Select network | Choose the blockchain network (e.g., Ethereum, BSC) from the dropdown. |
| ③ | Choose tokens | Pick the "from" and "to" tokens and enter the swap amount. |
| ④ | Adjust slippage (optional) | Increase tolerance (e.g., 1% → 5%) for volatile pairs. |
| ⑤ | Execute swap | Confirm the best auto-selected quote and complete the swap. |
① Gas Fees Explained
MetaMask swaps require gas fees paid in the network’s native token:
| Blockchain | Gas Token |
|------------|----------|
| Ethereum | ETH |
| BNB Smart Chain | BNB |
| Polygon | MATIC |
💡 Pro Tip: Use decentralized exchanges (DEXs) directly to avoid MetaMask’s additional 0.875% service fee.
② Network Selection
Swaps only work within the same blockchain. For cross-chain transfers, use MetaMask’s Bridge function.
③ Token Pairing
Select tokens from the dropdown menus. Lesser-known tokens may lack liquidity, causing swap failures.
④ Slippage Tolerance
Adjust slippage (default: 0.5%) to 5% for low-liquidity tokens to prevent transaction reversals.
⑤ Quote Aggregation
MetaMask auto-compares quotes via:
- AGG: Combines liquidity from multiple DEXs for better rates.
- RFQ: Uses pre-set prices to eliminate slippage.

Why Can’t I Swap? Common Issues & Fixes
1. Quote Fetching Error
- Cause: Insufficient liquidity for the token pair.
- Solution: Use a DEX like Uniswap/PancakeSwap directly or check token availability via DexScreener.
2. Slippage Error
- Cause: Price moved beyond your set tolerance.
- Solution: Raise slippage to 5–10% for low-volume tokens.
3. Insufficient Gas Fees
- Cause: Not enough native tokens to cover transaction costs.
- Solution: Reduce swap amount or top up gas tokens.
FAQs
Q: Why hasn’t my swap completed?
A: The transaction may still be processing (especially on Ethereum during congestion). Check Etherscan for status.
Q: What’s the 0.875% fee for?
A: This MetaMask service fee supports platform development. Avoid it by using DEXs directly.
Q: Are AGG or RFQ quotes better?
A: AGG is ideal for high-liquidity pairs; RFQ guarantees no slippage.
Final Tips
- Always verify token liquidity before swapping.
- For frequent swaps, bookmark reliable DEXs like Uniswap or PancakeSwap.
- Keep extra gas tokens for failed transactions.
