A BEP-20 token is a fungible token on BNB Smart Chain that follows the same interface as Ethereum's ERC-20. Writing the contract takes an afternoon with audited libraries. The real work is deciding what the token is for, designing supply and permissions that users can trust, and handling the legal questions a token raises.
BEP-20 versus ERC-20
BEP-20 is BNB Chain's name for its fungible token standard, and it mirrors ERC-20: totalSupply, balanceOf, transfer, approve, allowance, transferFrom, and the Transfer and Approval events. The BEP-20 description adds a getOwner() function, which returns the token owner and was used by the old Binance Chain bridge. In practice, a standard OpenZeppelin ERC-20 contract deployed on BSC is a BEP-20 token, and wallets, DEXs and explorers treat it as one. Because BSC is EVM-compatible, the same contract can be deployed to Ethereum or other EVM chains; the background on the network is in the guide to Binance Smart Chain.
You will also see "Binance-Peg" tokens on BSC. Those are BEP-20 representations of assets from other chains, issued by Binance's bridge, and they depend on that custodian.
Designing the token
Purpose first
Write one sentence explaining why the token exists and what holders can do with it: pay for a service, vote on governance, stake for access, or represent an in-game currency. If the honest answer is "so people can buy it and hope it goes up," you are designing something that regulators may view as a security and that users have learned to distrust.
Common features and their trade-offs
| Feature | What it does | Trust implication |
|---|---|---|
| Fixed supply | All tokens minted at deployment | Simple and easy to verify |
| Mintable | Owner can create more tokens | Holders must trust the minter; use caps, multisig and timelocks |
| Burnable | Holders can destroy tokens | Low risk |
| Pausable | Admin can freeze transfers | Useful in emergencies; also a censorship lever |
| Transfer taxes | Fee on every transfer or trade | Breaks some DeFi integrations; common in scam tokens |
| Blacklists or max-wallet limits | Restrict who can hold or trade | Often abused to trap buyers; scanners flag them |
| Permit (EIP-2612) | Gasless approvals via signatures | Better user experience; standard in OpenZeppelin |
Reflection and auto-liquidity tokens, popularized by SafeMoon in 2021, layered several of these mechanics. They are complex, gas-heavy and have a poor track record; the SafeMoon-style token guide explains why.
Supply and distribution
Publish the allocation (team, treasury, community, liquidity), vesting schedules enforced by contracts rather than promises, and who controls each wallet. Lock or vest team tokens. Buyers on BSC routinely check top holders on BscScan before buying.
Building and launching
- Write the contract using OpenZeppelin's ERC-20 implementation with only the extensions you need. Avoid custom transfer logic unless you have a strong reason.
- Test with Hardhat or Foundry: transfers, approvals, edge cases, role permissions and any fee logic.
- Deploy to BSC testnet (chain ID 97) and integrate with your app.
- Audit anything beyond a plain token, and get an independent smart contract audit before mainnet if the token connects to staking, vesting or treasury contracts.
- Deploy to mainnet (chain ID 56) from a secure key, ideally with ownership transferred to a multisig.
- Verify the source on BscScan so anyone can read the code.
- Add liquidity on a DEX if trading is intended, and lock the LP tokens or explain how liquidity is managed.
- Submit token info (logo, website, social links) to explorers and wallet token lists.
Deployment cost on BSC is low. The real costs are audits, legal review, liquidity, and the product the token is meant to serve.
Legal and compliance
In the US, the SEC applies the Howey test to decide whether a token sale is an investment contract. In the EU, MiCA regulates crypto-asset offerings and service providers, including white paper requirements for many token offerings. Stablecoins have their own regimes, including the US GENIUS Act signed in 2025. Promising returns, profit sharing or price support increases risk. Get advice before selling tokens to the public.
If you are deciding between chains, the Ethereum token development guide covers the same process on Ethereum, and DeFi token development covers governance and utility designs for protocols.
Frequently asked questions
Is a BEP-20 token the same as an ERC-20 token?
The interface is the same; the network differs. A BEP-20 token lives on BNB Smart Chain, an ERC-20 token on Ethereum. The same Solidity contract can be deployed to both.
How much does it cost to create a BEP-20 token?
Deployment gas on BSC is small. A professional launch also involves design, testing, an audit, legal review and liquidity, which are where most of the budget goes.
Do I need the getOwner function?
It is part of the BEP-20 description and harmless to include, but most modern tooling does not depend on it. Standard OpenZeppelin ERC-20 contracts work on BSC.
Why do token scanners flag some BEP-20 contracts?
Because features like hidden minting, adjustable taxes, blacklists and trading switches have been used in scams. Avoid them, or clearly justify and constrain them with multisigs and timelocks.
