Discover BEP20 vs ERC20 differences and follow a step‑by‑step guide to using cross‑chain bridges, exchanges, and tools for token conversion, avoiding risks.

In this article we outline the core differences between BEP20 and ERC20, and provide detailed step‑by‑step instructions for using cross‑chain bridges, exchanges, and third‑party tools. The clear procedural guide helps token holders convert assets between networks safely and efficiently. Later sections will also warn about common risks, so a thorough read is recommended.
BEP20 vs ERC20: Guide to Cross‑Chain Token Conversion flowchart

Tokens are digital units on a blockchain platform, usually specific to a particular application. They can be used for transactions, store of value, accessing digital assets, or obtaining governance and voting rights on the platform. To make a token compatible with its underlying chain, it must follow the appropriate token standard. This article focuses on the differences between the BEP20 and ERC20 standards and explains how to transfer between them.

Can BEP20 be converted to ERC20?

BEP20 tokens cannot be converted directly to ERC20. You need to use a cross‑chain bridge, an exchange that supports both BSC and Ethereum, or a dedicated bridging service to first move the assets to the target network and then complete the swap.

Common paths for cross‑chain conversion

  1. Cryptocurrency exchanges
  • Choose a major exchange that supports both Binance Smart Chain (BEP20) and Ethereum (ERC20). Deposit your BEP20 assets to the exchange, then withdraw them as ERC20.
  • Note for U.S. users: Use Binance.US or another U.S.-compliant exchange instead of the global Binance platform.
  1. Binance Smart Chain Bridge
  • Use the official Binance cross‑chain bridge (Binance Smart Chain Bridge) to bridge BEP20 tokens to the Ethereum network.
  • Fiat considerations: If you need to purchase BNB or ETH with fiat, you can do so via SEPA/SWIFT transfers or USD‑based payment methods on supported platforms.
  1. Third‑party cross‑chain bridges
  • Tools such as Multichain, cBridge, and others offer “one‑click bridge” functionality, suitable for users who prefer not to perform multiple deposits/withdrawals on an exchange.
  1. Swap services
  • Platforms like Changelly and Shapeshift allow you to swap BEP20 directly for ERC20, with a straightforward interface and no need to register a complex account.

Operational cautions

  • BEP2 vs. BEP20: BEP2 belongs to the Binance Chain (BNB Chain) network, while BEP20 belongs to Binance Smart Chain (BSC). Tokens on these two chains cannot be deposited or withdrawn directly to each other.
  • Similar address formats: BSC addresses look almost identical to ERC20 (Ethereum) addresses. Always verify the selected network when depositing or withdrawing to avoid loss of funds.
  • Network selection: The same token may be issued on multiple networks. Before sending, make sure your wallet or exchange is set to the correct network; otherwise you may encounter “deposit not credited” or “withdrawal failed” errors.

  • BEP20 is the token standard on BSC, designed to provide functionality similar to Ethereum’s ERC20 while also being compatible with Binance Chain’s BEP2. Since its launch, BSC has become a major competitor to Ethereum for DApp deployment.
  • ERC20 is the earliest and most widely adopted fungible‑token standard on Ethereum. Each token unit has the same value, offering high interoperability across the Ethereum ecosystem.

Quick FAQ

  • Can I send a BEP20 token directly to an ERC20 address?

No. The two belong to different chains and must be converted via a bridge or an exchange.

  • Are cross‑chain bridges safe?

Leading bridge services have undergone multiple security audits, but it is still advisable to test with a small amount before moving larger sums.

  • Are there extra fees?

Yes. The bridging process incurs two gas fees: one on the source chain (BSC, paid in BNB) and another on the destination chain (Ethereum, paid in ETH).
