I built an example app showing how to use @CoinbaseDev Embedded Wallets alongside @base Accounts (Sign in with Base) make your apps friendly to both crypto-forward and new-to-onchain users! uses: embedded wallets, base accounts, CDP token balances & faucet, ENS. code in 🧵
I have a feeling every OS that currently exists is sub-optimal for the AI era
Amazing how well this is coming together. Turns out @alchemy_run is the perfect way to build, test and deploy smart contracts to @coinbase

Our @CoinbaseDev Embedded Wallets are getting more powerful every week. Updates just landed: - React Native demo app (link👇) to jumpstart your mobile-first onchain app - Beautiful dashboards in CDP Portal for insights on your embedded wallet usage What should we ship next?🚀

10 years from now open standards like x402, A2A, AP2, and MCP will be viewed similarly to HTML, CSS, and HTTP are today. The majority of people never think about them, but they fundamentally shape their lives.

x402 + @Google just unlocked a new level for AI agents. Agents can actually pay each other now, with x402 powering the stablecoin rail inside Google’s new Agentic Payments Protocol (AP2). Really cool.
AI agents need money they can hold, reason about, and move programmatically. That is stablecoins. Google’s AP2 gives agents a standard to prove intent and execute payments, and x402 plugs crypto into it. AI picks, stablecoins pay - with audit trails, rules, and 24/7 settlement.

Great to see this Brian! The best way to build the agent ecosystem is open and together. Congrats to @coinbase for extending its x402 protocol to AP2.

If you think stablecoins are just for people, you’ve missed the plot. Crypto wallets and stablecoins are the optimal technology for agent to agent commerce and will unlock trillions in new value for consumers and merchants alike. Excited to partner with @coinbase @ethereumfndn…
