-Universal Bridge allows you to create both simple and advanced payment flows for bridging, swapping, onramping, and peer-to-peer purchases. It's been used to drive millions in NFT sales, bridge native tokens to brand new chains, send stablecoins between users, and more. To get started check out the [SDK functions](https://portal.thirdweb.com/typescript/v5/buy/quote), [API reference](https://bridge.thirdweb.com/reference), or [playground](https://playground.thirdweb.com/connect/pay).
