Yes, Built-In Swap Is Available
The Binance Web3 Wallet has a built-in Swap that aggregates multiple DEX liquidity pools to find optimal prices. Register on Binance.
Swap vs. Exchange Trading
Exchange: centralized order book, only listed tokens, lower fees. Swap: on-chain via smart contracts, any token with DEX liquidity, requires gas fees.
How to Swap
Web3 Wallet > Swap > select "From" token > select "To" token (or paste contract address) > enter amount > review price and gas > confirm.
Supported Chains
BNB Chain, Ethereum, Polygon, Arbitrum, etc. Cross-chain swaps require bridge functionality.
Gas Fees
BNB Chain: pennies. Polygon: near-zero. Ethereum: $5-50. L2s: much cheaper than mainnet.
Slippage Settings
Default 0.5-1%. Adjust higher for low-liquidity tokens (1-5%) or hot new tokens (5-15%). Too high invites MEV sandwich attacks.
Safety
Verify contract addresses from trusted sources. Watch for fake tokens. Only approve needed amounts. Compare prices with exchanges.
