BEP-20

What is BEP-20?

BEP-20 is the token standard for fungible tokens on BNB Smart Chain. Think of it as the rulebook that tells wallets and apps how to create, send, and track tokens, similar to ERC-20 on Ethereum. It’s the dress code that gets your token into the DeFi club, yes, it’s that simple.

How BEP-20 works

Here’s the quick walkthrough of what happens when someone creates and sends a BEP-20 token.

1. Create: A developer writes a token contract using smart contracts that define name, symbol, supply, and permissions.
2. Deploy: They publish the contract to BNB Smart Chain and mint tokens, usually to their wallet or a treasury address.
3. Send: You transfer the token to a friend, the contract updates balances, and you wait for transaction confirmation.
4. Fees: Gas is paid in BNB. If you run out of BNB, nothing moves.
5. Use: Tokens can be swapped on DEXs, staked in farms, or plugged into dApps that support the standard.

That’s the flow you’ll see again and again.

Why BEP-20 Matters

So, why should you care about this standard?

• Benefit: Fees on BNB Chain are known for Low Transaction Costs, so moving tokens doesn’t feel like buying a Rolex to send lunch money.
• Perspective: It’s compatible with popular Ethereum tooling, which means builders can ship fast and users get familiar wallet flows.
• Relevance: You’ll meet BEP-20 in swaps, staking, launchpads, and even stablecoins. Unlike fiat currencies, transfers settle on-chain without bank approvals.

Key Characteristics of BEP-20

Spot the features that make this standard practical and widely used:

• Standard: Common functions like transfer, approve, and balanceOf keep wallets and exchanges in sync.
• Fees: Gas is paid in BNB, typically lower than many Layer 1s during peak hours.
• Supply: Can be fixed, mintable, or burnable, depending on the contract design.
• Decimals: Often 18, which keeps math in line with ERC-20 habits.
• EVM: Works with MetaMask and other EVM tools, so setup feels familiar.

Variations

Think of these as cousins in the token family:

• ERC-20: The Ethereum counterpart, similar interface, different chain and fees.
• BEP-2: An older Binance standard for the Beacon Chain, not EVM compatible.
• BEP-721: For NFTs, one-of-one tokens rather than fungible units.
• Wrapped: Tokens bridged from other chains to behave like native BEP-20 assets.

Example

Buying CAKE on PancakeSwap gives you a BEP-20 token that you can stake in a farm or send to a friend using a BNB Smart Chain address.

Fun Fact

BEP stands for Binance Evolution Proposal, and the 20 nods to the ERC-20 naming vibe. Also, Binance Smart Chain rebranded to BNB Chain, but the BEP-20 label stuck like a classic sneaker drop.

Wrap-Up

BEP-20 is the shared rulebook that lets tokens work smoothly across BNB Chain apps, making transfers quick, cheap, and easy to build around.
