name: BNB description: Assist with BNB Chain transactions, BEP-20 tokens, gas fees, and cross-chain transfers. metadata: {"clawdbot":{"emoji":"🔶","os":["linux","darwin","win32"]}}

Network Clarity (Critical)

  • "BNB Chain" is the main smart contract chain — formerly Binance Smart Chain (BSC)
  • "BNB Beacon Chain" was for staking — deprecated, merged into BNB Chain
  • BEP-20 tokens on BNB Chain — equivalent to ERC-20, EVM compatible
  • Same address format as Ethereum — 0x... addresses work on both
  • DIFFERENT networks — sending to wrong network loses funds

BNB Token

  • Native gas token for BNB Chain — needed for all transactions
  • Also available as BEP-2 (legacy), ERC-20 (Ethereum), and other wrapped versions
  • BNB on Binance exchange can be withdrawn to multiple networks — choose carefully
  • Burning mechanism reduces supply — quarterly burns based on trading volume

Gas and Fees

  • EVM compatible gas model — same as Ethereum but cheaper
  • Gas prices typically 3-5 gwei — much lower than Ethereum
  • Standard transfer ~21,000 gas — costs fraction of a cent
  • Complex DeFi transactions cost more — but still very cheap
  • Fast block time (3 seconds) — quick confirmations

BEP-20 Tokens

  • Same interface as ERC-20 — all ERC-20 tooling works
  • Approve + transfer pattern — same as Ethereum
  • Many tokens have same name as Ethereum versions — but different contracts
  • Verify contract address on bscscan.com — scam tokens everywhere
  • Popular tokens: USDT, USDC, BUSD (deprecated), CAKE, various memes

Cross-Chain Transfers

  • Binance exchange supports direct withdrawal to BNB Chain — easiest method
  • Bridges: cBridge, Multichain, Stargate — verify bridge reputation
  • BNB Chain ↔ Ethereum requires bridge — not same network despite same addresses
  • opBNB is L2 on BNB Chain — even lower fees, different RPC
  • Wrapped assets need unwrapping — bridged ETH is not native ETH

DeFi Ecosystem

  • PancakeSwap is largest DEX — similar to Uniswap
  • Venus for lending/borrowing — similar to Aave
  • Lower TVL than Ethereum DeFi — but still significant
  • Higher rug pull risk — less auditing culture
  • Verify contracts before interacting — bscscan shows verification status

Wallet Configuration

  • MetaMask works natively — add BNB Chain network
  • Chain ID: 56 — RPC: https://bsc-dataseed.binance.org
  • Block explorer: bscscan.com — verify transactions
  • Trust Wallet has native support — no manual network add
  • Hardware wallets work via MetaMask — same as Ethereum

Staking

  • Stake BNB with validators — earn staking rewards
  • Minimum stake varies by validator — typically 1 BNB minimum
  • Unbonding period: 7 days — funds locked during unstaking
  • Slashing risk exists — choose reliable validators
  • Liquid staking options: stkBNB, ankrBNB — maintain liquidity while staking

Common Scams

  • "USDT" with wrong contract — verify against official addresses
  • Honeypot tokens — can buy but not sell
  • Fake PancakeSwap sites — always verify URL
  • Airdropped tokens you didn't request — often scam triggers
  • "Validators" asking for private keys — never share

Common Issues

  • "Insufficient funds for gas" — need BNB for gas, not just tokens
  • Wrong network — ETH sent to BNB Chain address (same address, different chains)
  • High slippage on DEX — low liquidity tokens
  • Transaction pending — try increasing gas price
  • Contract interaction failed — check approval and balance

Security

  • Same security model as Ethereum — private key = full access
  • Revoke unused approvals — bscscan.com token approval checker
  • Verify all contract addresses — especially for popular tokens
  • Use hardware wallet for large amounts — same setup as Ethereum
  • Don't interact with unknown airdropped tokens — can contain malicious contracts
