Converting ERC-20 tokens from the Ethereum blockchain to BEP-20 tokens on the Binance Smart Chain (BSC) is a common need for users seeking faster transactions and lower fees. Whether you're managing stablecoins like USDT or other digital assets, understanding how to bridge between these two networks safely and efficiently is essential. This guide walks you through the most reliable methods, highlights key differences between ERC-20 and BEP-20 standards, and offers practical tips to avoid costly mistakes.
Understanding ERC-20 vs BEP-20
Before converting tokens, it's important to understand what sets these two token standards apart. Both allow for the creation and transfer of fungible tokens, but they operate on different blockchains with distinct performance characteristics.
Blockchain Network
- ERC-20: Built on the Ethereum network, this is the most widely adopted token standard in the crypto space.
- BEP-20: Native to Binance Smart Chain (now BNB Smart Chain), designed to be compatible with Ethereum’s tooling while offering improved speed and cost efficiency.
Transaction Speed & Fees
- ERC-20: Transactions can be slow during peak times, and gas fees are often high due to network congestion.
- BEP-20: Offers faster confirmation times (around 3 seconds per block) and significantly lower transaction costs—often less than $0.10.
Consensus Mechanism
- ERC-20 (Ethereum): Uses Proof-of-Stake (PoS) following the Ethereum 2.0 upgrade.
- BEP-20 (BSC): Relies on Proof-of-Staked Authority (PoSA), a hybrid model that prioritizes speed and efficiency over full decentralization.
Smart Contract Compatibility
Thanks to BSC’s Ethereum Virtual Machine (EVM) compatibility, smart contracts written for Ethereum can typically run on BSC with minimal changes. This enables seamless cross-chain bridging of tokens.
Use Cases & Adoption
- ERC-20 dominates in decentralized finance (DeFi), NFTs, and institutional-grade applications where security and decentralization are top priorities.
- BEP-20 thrives in low-cost DeFi platforms, gaming dApps, and projects within the Binance ecosystem.

Step-by-Step: Convert ERC-20 to BEP-20
There are three primary ways to convert ERC-20 tokens into BEP-20 format: using an official bridge, a decentralized cross-chain solution, or a centralized exchange. Each method has its pros and cons depending on your needs for speed, control, and convenience.
Method 1: Using Binance Bridge (Official & Recommended)
The Binance Bridge is the most straightforward and secure option for transferring assets between Ethereum and BSC.
- Visit Binance Bridge
Go to the official Binance Bridge website and connect your wallet (e.g., MetaMask, Trust Wallet). - Select Token & Amount
Choose the ERC-20 token you wish to convert (like USDT, ETH, or others) and enter the amount. Set Source and Destination Networks
- From: Ethereum (ERC-20)
- To: BNB Smart Chain (BEP-20)
- Confirm Transaction
Approve the transaction in your wallet. You’ll need ETH to cover Ethereum gas fees. - Receive BEP-20 Tokens
Once processed (usually within minutes), the equivalent BEP-20 tokens will appear in your wallet under the same address.
This method is non-custodial—meaning you retain control of your funds throughout the process.
Method 2: Using a Decentralized Cross-Chain Bridge
For users who prefer non-custodial solutions outside of Binance, several trusted decentralized bridges support ERC-20 to BEP-20 transfers:
- Multichain (multichain.org)
- cBridge by Celer Network (cbridge.celer.network)
- Synapse Protocol (synapseprotocol.com)
Steps:
- Connect your wallet to the chosen platform.
- Select Ethereum as the source chain and BSC as the destination.
- Enter the token amount and confirm the swap.
- Pay required gas fees in ETH.
- Wait for finality—processing time ranges from 5 to 20 minutes.
These platforms offer greater flexibility across multiple chains but may carry slightly higher slippage or fees depending on liquidity.

Method 3: Manual Swap via Centralized Exchange
If you're already using a centralized exchange like Binance, this method offers simplicity at the cost of temporary custody loss.
- Deposit ERC-20 Tokens
Send your ERC-20 tokens (e.g., USDT) to your exchange deposit address using the Ethereum network. - Wait for Confirmation
Allow time for blockchain confirmations (usually 15–30 minutes). - Withdraw as BEP-20
Navigate to the withdrawal section, select the same token, but choose BSC (BEP-20) as the network. Enter your BSC-compatible wallet address (starting with0x).
This method avoids direct interaction with bridges but requires trust in the exchange’s internal accounting system.
Frequently Asked Questions
Q: Are ERC-20 and BEP-20 tokens interchangeable?
A: Not directly—they exist on separate blockchains. However, they can be bridged using trusted platforms like Binance Bridge or Multichain.
Q: Do I need BNB to receive BEP-20 tokens?
A: Yes. To interact with BSC (e.g., receive tokens, make trades), your wallet must have a small amount of BNB for gas fees.
Q: Can all ERC-20 tokens be converted to BEP-20?
A: Only if the token has a supported BEP-20 version. Popular tokens like USDT, ETH (as WETH), and BUSD are widely available on both chains.
Q: Is it safe to use cross-chain bridges?
A: Reputable bridges like Binance Bridge and cBridge are generally secure, but always verify URLs, use small test amounts first, and avoid suspicious platforms.
Q: Why convert from ERC-20 to BEP-20?
A: To benefit from lower transaction fees and faster processing speeds on BSC, especially when engaging with DeFi apps or paying for services.
Q: Will my wallet address remain the same after conversion?
A: Yes—if your wallet supports both chains (like MetaMask with BSC added), your address remains unchanged across Ethereum and BSC.
Key Tips for Safe Conversion
- Always double-check network selections—sending tokens to the wrong chain can result in permanent loss.
- Use only well-known bridges and exchanges; avoid unverified third-party services.
- Keep a small reserve of ETH for Ethereum gas and BNB for BSC operations.
- Perform a test transfer with a small amount before moving large sums.
Whether you're optimizing for cost, speed, or ecosystem access, converting ERC-20 to BEP-20 opens up new possibilities in the evolving Web3 landscape.
