name: BNB description: Assist with BNB Chain transactions, BEP-20 tokens, gas fees, and cross-chain transfers. metadata: {"clawdbot":{"emoji":"๐ถ","os":["linux","darwin","win32"]}}
Network Clarity (Critical)
- "BNB Chain" is the main smart contract chain โ formerly Binance Smart Chain (BSC)
- "BNB Beacon Chain" was for staking โ deprecated, merged into BNB Chain
- BEP-20 tokens on BNB Chain โ equivalent to ERC-20, EVM compatible
- Same address format as Ethereum โ 0x... addresses work on both
- DIFFERENT networks โ sending to wrong network loses funds
BNB Token
- Native gas token for BNB Chain โ 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- BNB on Binance exchange can be withdrawn to multiple networks โ choose carefully
- Burning mechanism reduces supply โ quarterly burns based on trading volume
Gas and Fees
- EVM compatible gas model โ same as Ethereum but cheaper
- Gas prices typically 3-5 gwei โ much lower than Ethereum
- Standard transfer ~21,000 gas โ costs fraction of a cent
- Complex DeFi transactions cost more โ but still very cheap
- Fast block time (3 seconds) โ quick confirmations
BEP-20 Tokens
- Same interface as ERC-20 โ all ERC-20 tooling works
- Approve + transfer pattern โ same as Ethereum
- Many tokens have same name as Ethereum versions โ but different contracts
- Verify contract address on bscscan.com โ scam tokens everywhere
- Popular tokens: USDT, USDC, BUSD (deprecated), CAKE, various memes
Cross-Chain Transfers
- Binance exchange supports direct withdrawal to BNB Chain โ easiest method
- Bridges: cBridge, Multichain, Stargate โ verify bridge reputation
- BNB Chain โ Ethereum requires bridge โ not same network despite same addresses
- opBNB is L2 on BNB Chain โ even lower fees, different RPC
- Wrapped assets need unwrapping โ bridged ETH is not native ETH
DeFi Ecosystem
- PancakeSwap is largest DEX โ similar to Uniswap
- Venus for lending/borrowing โ similar to Aave
- Lower TVL than Ethereum DeFi โ but still significant
- Higher rug pull risk โ less auditing culture
- Verify contracts before interacting โ bscscan shows verification status
Wallet Configuration
- MetaMask works natively โ add BNB Chain network
- Chain ID: 56 โ RPC: https://bsc-dataseed.binance.org
- Block explorer: bscscan.com โ verify transactions
- Trust Wallet has native support โ no manual network add
- Hardware wallets work via MetaMask โ same as Ethereum
Staking
- Stake BNB with validators โ earn staking rewards
- Minimum stake varies by validator โ typically 1 BNB minimum
- Unbonding period: 7 days โ funds locked during unstaking
- Slashing risk exists โ choose reliable validators
- Liquid staking options: stkBNB, ankrBNB โ maintain liquidity while staking
Common Scams
- "USDT" with wrong contract โ verify against official addresses
- Honeypot tokens โ can buy but not sell
- Fake PancakeSwap sites โ always verify URL
- Airdropped tokens you didn't request โ often scam triggers
- "Validators" asking for private keys โ never share
Common Issues
- "Insufficient funds for gas" โ need BNB for gas, not just tokens
- Wrong network โ ETH sent to BNB Chain address (same address, different chains)
- High slippage on DEX โ low liquidity tokens
- Transaction pending โ try increasing gas price
- Contract interaction failed โ check approval and balance
Security
- Same security model as Ethereum โ private key = full access
- Revoke unused approvals โ bscscan.com token approval checker
- Verify all contract addresses โ especially for popular tokens
- Use hardware wallet for large amounts โ same setup as Ethereum
- Don't interact with unknown airdropped tokens โ can contain malicious contracts
