What Are ERC-20 Tokens?
ERC-20 is the technical standard for tokens on Ethereum. If you've ever held USDC, USDT, LINK, UNI, or thousands of other tokens on Ethereum, you've used ERC-20 tokens. These tokens can be bridged to PulseChain where you'll benefit from:
- Lower gas fees: Transactions cost fractions of a cent on PulseChain
- Faster confirmations: 3-second block times vs Ethereum's 12 seconds
- DeFi opportunities: Trade, farm, and stake on PulseChain DEXs
- Portfolio diversification: Access PulseChain's growing ecosystem
Which ERC-20 Tokens Can Be Bridged?
PulseChain Bridge supports a wide range of ERC-20 tokens. Here's the current status:
| Token | Symbol | Bridge Support | PulseChain Liquidity |
|---|---|---|---|
| USD Coin | USDC | ✅ Full Support | ⭐⭐⭐⭐⭐ Excellent |
| Tether | USDT | ✅ Full Support | ⭐⭐⭐⭐⭐ Excellent |
| Wrapped Bitcoin | WBTC | ✅ Full Support | ⭐⭐⭐⭐ Very Good |
| DAI Stablecoin | DAI | ✅ Full Support | ⭐⭐⭐⭐ Very Good |
| Chainlink | LINK | ✅ Full Support | ⭐⭐⭐ Good |
| Uniswap | UNI | ✅ Full Support | ⭐⭐⭐ Good |
| Shiba Inu | SHIB | ✅ Full Support | ⭐⭐ Moderate |
| HEX | HEX | ✅ Full Support | ⭐⭐⭐⭐⭐ Excellent |
💡 Not Sure If Your Token Is Supported?
Connect your wallet to PulseChain Bridge and search for your token in the dropdown. If it appears with a balance, it's supported. Generally, any ERC-20 token with reasonable liquidity can be bridged.
How ERC-20 Bridging Works
When you bridge an ERC-20 token to PulseChain, here's what happens technically:
The Bridge Process
- Lock: Your ERC-20 tokens are locked in the bridge's smart contract on Ethereum
- Verify: Validators confirm the deposit transaction
- Mint: An equivalent amount of wrapped tokens are minted on PulseChain
- Receive: The wrapped tokens arrive in your wallet on PulseChain
The reverse process works similarly: burn tokens on PulseChain, unlock originals on Ethereum.
Wrapped vs Native Tokens
Bridged ERC-20 tokens on PulseChain are "wrapped" versions backed 1:1 by the original tokens locked on Ethereum. For example:
- USDC on Ethereum → bridged USDC on PulseChain
- WBTC on Ethereum → bridged WBTC on PulseChain
These wrapped tokens function identically to their originals and can be bridged back at any time.
Step-by-Step: Bridge Any ERC-20 Token
Prerequisites
- ERC-20 tokens in your wallet on Ethereum
- ETH for gas fees (~$5-15)
- MetaMask or compatible wallet
- PulseChain network added to your wallet
Step 1: Connect to PulseChain Bridge
- Go to pulse-bridge.com
- Click "Connect Wallet"
- Select your wallet provider
- Approve the connection
- Ensure you're on Ethereum network
Step 2: Select Your ERC-20 Token
- Click the token dropdown in the "From" section
- Search for your token by name or symbol
- If not listed, paste the token's contract address
- Select the token
⚠️ Verify Token Contracts
If pasting a contract address, double-check it on Etherscan first. Scammers create fake tokens with similar names. Only use verified contract addresses.
Step 3: Approve the Token
Before bridging an ERC-20 token for the first time, you must approve the bridge contract to spend your tokens:
- Click "Approve [Token Name]"
- Choose approval amount:
- Exact amount: More secure, requires approval each time
- Unlimited: Convenient, one-time approval
- Confirm the approval in your wallet
- Wait for confirmation (1-2 minutes)
Step 4: Enter Amount and Bridge
- Enter the amount to bridge
- Review the estimated receive amount
- Check the fee breakdown
- Click "Bridge"
- Confirm the transaction in your wallet
Step 5: Receive on PulseChain
- Wait 3-5 minutes for the bridge to process
- Switch your wallet to PulseChain network
- Add the token to your wallet if not visible
- Verify your balance on PulseScan

Bridge ERC-20 TokensFee Breakdown for ERC-20 Bridging
| Fee Type | Amount | Notes |
|---|---|---|
| Token Approval (one-time) | $1-4 | Per token, first time only |
| Ethereum Gas | $3-12 | Varies with network congestion |
| Bridge Fee | $1-3 | Fixed fee per transaction |
| Total (First Bridge) | $5-19 | Includes approval |
| Total (Subsequent) | $4-15 | No approval needed |
Adding Bridged Tokens to Your Wallet
Bridged ERC-20 tokens may not appear automatically in your wallet. Here's how to add them:
MetaMask
- Switch to PulseChain network
- Click "Import tokens" at the bottom
- Paste the token's PulseChain contract address
- The symbol and decimals should auto-fill
- Click "Add Custom Token"
Finding Token Contract Addresses
To find the correct contract address for bridged tokens:
- Go to PulseScan
- Search for the token name
- Verify it's the bridged version from PulseChain Bridge
- Copy the contract address
Common ERC-20 Bridging Issues
"Token not showing in bridge dropdown"
Try pasting the token's Ethereum contract address directly. Some newer or less common tokens may not be in the default list but are still supported.
"Approval transaction failed"
This usually means insufficient ETH for gas. Add more ETH to cover gas fees and try again.
"Bridge transaction pending for too long"
Check your transaction on Etherscan. If it's confirmed there but tokens haven't arrived on PulseChain after 15 minutes, the bridge may be processing a backlog. Contact support if it exceeds 30 minutes.
"Received less tokens than expected"
Some tokens have transfer taxes built into their contracts. The bridge transfers the net amount after any token-level fees.
"Can't find bridged token on PulseChain"
The token needs to be manually added to your wallet. Find the contract address on PulseScan and import it as a custom token.
Best Practices for ERC-20 Bridging
Before Bridging
- Check liquidity: Verify the token has trading pairs on PulseChain DEXs
- Test first: Bridge a small amount before moving significant holdings
- Time it right: Bridge when Ethereum gas is low (weekends, off-peak hours)
- Verify contracts: Double-check token addresses on official sources
After Bridging
- Add to wallet: Import the bridged token immediately
- Verify on PulseScan: Confirm the transaction and balance
- Get PLS for gas: You'll need PLS for transactions on PulseChain
- Explore DeFi: Check PulseX for trading and liquidity options
Tokens That Cannot Be Bridged
Not all ERC-20 tokens can be bridged. These typically won't work:
- Rebasing tokens: Tokens that automatically adjust supply (some yield tokens)
- Non-standard ERC-20: Tokens with unusual implementations
- LP tokens: Liquidity provider tokens from other DEXs
- NFT-like tokens: Tokens that behave more like NFTs
- Blacklisted tokens: Tokens associated with known scams
Frequently Asked Questions
Can I bridge any ERC-20 token?
Most standard ERC-20 tokens are supported. However, some tokens with non-standard implementations or very low liquidity may not be bridgeable.
Are bridged tokens the same as native tokens?
Bridged tokens are wrapped versions backed 1:1 by original tokens locked on Ethereum. They function identically and can be bridged back at any time.
What's the minimum amount I can bridge?
There's no strict minimum, but given gas fees, bridging less than $50-100 in tokens is usually not cost-effective.
Can I bridge tokens directly to another wallet?
Most bridges send to the same wallet address on PulseChain. Some advanced bridges support different destination addresses.
How do I bridge tokens back to Ethereum?
Connect to the bridge on PulseChain network, select the token, and reverse the process. Your original tokens will be unlocked on Ethereum.
