👏 "the sticker price you see in the UI isn't necessarily what you'll get in your wallet once the swap tx is mined." Is your swap provider _really_ showing you the best all-in price?

Smart contract wallets, like @coinbasewallet, unlock advanced possibilities such as two-factor authentication, multi-sig support, and gas abstraction. Did you know that you can seamlessly handle token swaps in your app with smart contract or multi-sig wallets using @0xproject's Swap API Permit2 endpoint? Check out our guide below to implement: 1. Fetch a price / quote 2. Sign the EIP-712 message 3. Append the signature length & data to the transaction 4. Submit the trade with enhanced security
