BEP20 token development means designing, writing and launching a fungible token on BNB Smart Chain (BSC). A BEP-20 token uses the same interface as Ethereum's ERC-20, and audited libraries let a developer write the contract in a few hours. Most of the work lies in the token's purpose, its supply and permissions, the launch, and the legal questions a token raises.
BEP-20 versus ERC-20
BEP-20 is BNB Chain's fungible token standard. It was derived from ERC-20 and uses the same core functions and events:
totalSupply,balanceOf,transfer,transferFrom,approveandallowance.- The
TransferandApprovalevents.
The BEP-20 text makes symbol and decimals required, while ERC-20 leaves them optional. Binance's earlier BEP-20 documentation also listed a getOwner() function, which the old Binance Chain bridge used, but the current BEP-20 text in BNB Chain's BEPs repository no longer lists getOwner().
OpenZeppelin's standard ERC-20 contract includes name, symbol and decimals. Deployed on BSC, that contract is a BEP-20 token, and wallets, DEXs and explorers treat it as one. BSC is EVM-compatible, so the same contract can also deploy to Ethereum and other EVM chains. The Binance Smart Chain development guide covers the network itself.
BSC also carries "Binance-Peg" tokens, which are BEP-20 versions of assets from other chains. Binance's bridge issues them, so their value depends on Binance as custodian.
Designing the token
Purpose
A token needs a stated job. Holders might pay for a service with it, vote on governance, stake it for access, or spend it as an in-game currency. A token whose only purpose is resale at a higher price is more likely to be treated as an investment, and buyers on BSC have learned to distrust such tokens.
Common features and their trade-offs
| Feature | What it does | Effect on trust |
|---|---|---|
| Fixed supply | The contract mints all tokens at deployment | Simple and easy to verify |
| Mintable | The owner can create more tokens | Holders must trust the minter, so the contract needs a supply cap, a multisig (a wallet that needs several signers) and a timelock (a delay before changes take effect) |
| Burnable | Holders can destroy their own tokens | Low risk |
| Pausable | An admin can freeze all transfers | Useful in an emergency, but an admin can also use it to block users |
| Transfer taxes | The contract takes a fee on every transfer or trade | Breaks some DeFi integrations and is common in scam tokens |
| Blacklists or max-wallet limits | The owner restricts who can hold or trade | Often used to trap buyers, and automated token scanners flag these functions |
| Permit (EIP-2612) | Users approve spending with a signature instead of a transaction | Saves a transaction, and OpenZeppelin includes it as an extension |
Reflection and auto-liquidity tokens were made popular by SafeMoon in 2021. They charge a transfer tax and send part of it to holders ("reflection") and part of it into a DEX pool ("auto-liquidity"). Such tokens are complex and use a lot of gas, and many of them failed. The SafeMoon-style token guide explains how they work and why they failed.
Supply and distribution
A token launch should publish the allocation to the team, the treasury, the community and liquidity. Vesting contracts, not promises, should enforce the team's lockups, and the launch should name who controls each large wallet. Buyers on BSC check the top holders on BscScan before they buy.
How to create a BEP20 token: step by step
- Write the contract with OpenZeppelin's ERC-20 implementation and only the extensions the token needs, since custom transfer logic adds risk and needs a clear reason.
- Test with Hardhat or Foundry, covering transfers, approvals, edge cases, role permissions and any fee logic.
- Deploy to BSC testnet (chain ID 97) and connect the token to the app that will use it.
- Audit any token that goes beyond a plain ERC-20. A token connected to staking, vesting or treasury contracts needs an independent smart contract audit before mainnet.
- Deploy to mainnet (chain ID 56) from a secure key, and move ownership to a multisig.
- Verify the source code on BscScan so anyone can read it.
- Add liquidity on a DEX such as PancakeSwap if the token will trade. The DEX gives the project LP tokens that represent its share of the pool, so lock those LP tokens or publish how the liquidity is managed.
- Submit token information such as the logo, website and social links to explorers and to wallet token lists.
No-code token generators also deploy BEP-20 tokens. A generated contract should still be verified on BscScan and read line by line, because some generators add owner functions that buyers distrust.
BEP20 token development costs
Gas for the deployment itself is small: a typical ERC-20 deployment uses about 1 to 1.5 million gas, and at BSC's minimum gas price of 0.05 gwei, set in October 2025, that deployment costs about 0.00005 to 0.000075 BNB. These figures are estimates, since the gas used depends on the contract.
The larger costs come from other work:
- Token design and documentation.
- Testing and an independent audit for any token with extra logic.
- Legal review of the token and of any sale.
- The liquidity that pairs with the token on a DEX.
- The product that the token serves.
Choosing a BEP20 token development company
A firm that builds BEP-20 tokens should answer these questions clearly:
- Which contract functions can the owner call after launch, and who holds the owner key?
- Does the contract use OpenZeppelin's audited code, or custom transfer logic?
- Which tests does the firm deliver, and will an independent auditor review the code?
- Will the source code be verified on BscScan under the client's own deployer address?
- Does the firm hand over the full source code and deployment scripts?
Legal and compliance
In the US, the SEC applies the Howey test to decide whether a token sale is an investment contract. In a March 2026 interpretive release, the SEC sorted crypto assets into five groups: digital commodities, digital collectibles, digital tools, stablecoins and digital securities. The release also separated the token from the sale, so a token can be a non-security while its sale is still a securities offering. In August 2026 the SEC proposed new offering exemptions for crypto assets, but the proposal is not yet a final rule.
In the EU, MiCA regulates crypto-asset offerings and service providers and requires a white paper for most public token offers. Stablecoins have their own rules, including the US GENIUS Act signed in 2025. Promises of returns, profit sharing or price support raise the legal risk of any token.
The ERC-20 token development guide covers the same process on Ethereum, and the DeFi token development guide 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, but the network differs. A BEP-20 token lives on BNB Smart Chain, and an ERC-20 token lives on Ethereum, though the same Solidity contract can deploy to both.
How much does it cost to create a BEP-20 token?
The deployment gas costs a tiny fraction of one BNB. A professional launch also pays for design, testing, an audit, legal review and liquidity, and those items make up most of the budget.
Does a BEP-20 token need the getOwner function?
No. Binance's earlier BEP-20 documentation listed it for the old Binance Chain bridge, but the current BEP-20 text does not. Standard OpenZeppelin ERC-20 contracts work on BSC without it.
Why do token scanners flag some BEP-20 contracts?
Scam tokens have used hidden minting, adjustable taxes, blacklists and trading switches. Scanners flag those features wherever they appear, so a legitimate token either leaves them out or limits them with a multisig and a timelock.
