Native x402 support just landed in the CDP SDK. Add x402 payments to your app, or spin up x402-gated endpoints, in 3 lines of code. Coinbase handles wallets, multi-chain support, and facilitator auth, all in a single SDK. ↓ [Spoken audio]: X4 2 SDK is great but you have to assemble all the building blocks by yourself. So today we're launching CDP X4 2 SDK to help you have a better developer experience by helping you manage your wallets, set spend control and it also extends the existing X4 2 SDK. With CDP X4 2 SDK you don't need to juggle keys anymore so for example if you're trying to set an account per agent or user you won't need to have a private key for each of them and manage all those keys, you would just use CDPx4 to client and the only credential you would have would be the CDP API keys. It also helps your agent to be ready for making payments without you needing to define the opto or exact scheme per network and by just using CDPx4 to client, it would already be prepared to make payments on exact and opto based on Solana and you can can enable other networks that CDP facilitated or handles like Polygon or World or set batch settlement to be true. One of the most useful features it brings to the table is spent control. So you can easily define what is the maximum amount you want your agent to be able to pay per call or even set a allow list for network or pay addresses. You can adopt it in one line and it's backward compatible. So you can just drop CDPX4 to client in your existing flow or use it with your existing X4 to hooks. Overall, it just improves your DevX and you have to write less code. So instead of having to define every scheme, for example, wiring up the facilitator and setting up the networks, all you would do on the seller side is just use create X4 to server and name the price. And your server is ready to accept payment on both Solana and base. And you could always overwrite that to change the scheme you're using to opt to or bad settlement and define the only network you want to be using. It also helps you support Pyramid 2 with just one line of code so your users wouldn't have to have gas tokens to use OPTO scheme or other tokens like USDT that doesn't support 309. And it auto configures Bazaar per root so you don't have to manually handle that but you can overwrite it as you want. CDPX4 to SDK is live today and I hope you have fun building with it.
