One component. Every USDC payment flow. That's what Whisk is. I built @usewhisk because I was tired of rewriting the same stablecoin flow on every project, and tired of answering "how do I plug stablecoin payments into my app?" . Drop <WhiskSend /> into a React app and you get same-chain sends, cross-chain bridges over CCTP, and stablecoin swaps from one API. EVM and Solana wallets in the same flow. Fees are itemized before the user signs. If a bridge burns USDC but the mint stalls mid-flight, Whisk picks it up and finishes the job. Theme it with CSS variables so it feels native to your product. Headless mode if you're not on React. Built on @circle App Kit. Live across 19 testnet chains including @arc. Mainnet next. usewhisk.xyz Big thanks to the @BuildOnCircle team. App Kit handled the heavy plumbing (CCTP, attestations, wallets) so Whisk could focus entirely on DX.
