The honest answer is "less than the names suggest, and more than zero." Same interface, same tooling, different chain — and three practical differences that actually change decisions for issuers.
What's the difference between BEP-20 and ERC-20?
BEP-20 is BNB Chain's token standard and it's interface-compatible with Ethereum's ERC-20 — the same functions, the same wallet and tooling support, effectively the same contract code deployed to a different chain. A BEP-20 token is not a different kind of asset; it's an ERC-20-pattern token living on BSC's rails. What differs is everything around the contract: gas costs (fractions of a cent on BNB Chain vs Ethereum's variable fees), block speed (0.45 seconds on BSC since the January 2026 Fermi fork), the surrounding DEX ecosystem (PancakeSwap vs Uniswap), and the buyer culture each chain trained. Issuers choose between them by choosing a chain, not a standard.
What actually changes for an issuer?
Three things with teeth: launch economics, market context, and the trust checks your token will face. Economics — deploying, seeding, locking, and distributing on BNB Chain costs cents in gas end-to-end, which makes proper token-ops (testnet runs, staggered locks, batched distributions) affordable in a way Ethereum mainnet still punishes. Market context — BSC's launch culture is retail-fast and memecoin-heavy with PancakeSwap as the center of gravity, versus Ethereum's institutional skew; the same token reads differently in each room. Trust checks — BSC buyers lead with ownership-renouncement and honeypot scans (the chain's scam history built that reflex), so a BEP-20 launch carries a specific checklist that an Ethereum launch orders differently.
What are the gotchas moving between the standards?
Decimals, bridged assets, and address confusion. The classic: USDT on BNB Chain uses 18 decimals, not the 6 it uses on Ethereum — hardcoded-decimal assumptions have burned real integrations and real distribution batches; always read decimals from the contract. Second: major stablecoins on BSC are Binance-Peg bridged versions (USDT 0x55d398…7955, USDC 0x8AC76a…580d), not native issuances — same tickers, different contracts, different trust assumptions; never assume an Ethereum address maps across. Third: BUSD is deprecated — minting halted in 2023 — and any content or integration still referencing it as live is out of date. None of these are contract-standard issues; all of them are the chain-context differences that actually cause incidents.
Can the same project issue on both?
Yes — multichain deployments of the same token are routine, and the operational question is keeping supply, addresses, and locks legible across chains. Publish the canonical contract address per chain in one place; use bridges or native multichain issuance deliberately rather than letting third-party wrapped versions define your token; and mirror the trust stack per chain — a locked pool on BSC doesn't cover the Ethereum pool, and buyers on each chain check their own explorer. Tooling-wise this is where standard-compatibility pays: the same audited templates, locks, and vesting work on both sides (MintPlus deploys ERC-20 and BEP-20 from one flow, free).
FAQ
Is a BEP-20 token an ERC-20 token? Functionally yes — same interface and behavior, deployed on BNB Chain instead of Ethereum. Wallets and tools treat them identically apart from the network setting.
Which is cheaper to launch on? BNB Chain by orders of magnitude on gas: the full launch sequence — deploy, seed, lock, distribute — costs cents in network fees at BSC's 0.05 gwei floor (as of August 2026).
Why does USDT have 18 decimals on BSC? Binance-Peg USDT was issued with BSC's conventional 18 decimals rather than Ethereum USDT's 6. It's the single most common cross-chain integration bug — read decimals from the contract, never assume.
Is BUSD still a thing? No — minting was halted in 2023 and balances were converted. Don't build or write anything that treats BUSD as live.
