Codex just read my diet/weight history directly from my MacroFactor app on Mac using the new computer use, and gave me a new cutting plan. It also wrote this new plan into my tracking app which will sync to my phone so I can track wherever I go. No mcp/cli…

Introducing... Zora Coins Agent 🤖

An AI agent that uses Base Account Spend Permissions, @CoinbaseDev server wallets and @zoradevs SDK to buy you any creator coin you want

Just give it the handle and it will do the rest, no clicks, no pop-ups, all managed by spend permissions

[wilson.base.eth @WilsonCusack]

Spend Permissions can give your app super powers: from subscriptions to streaming payments. But they've been too hard to use.

Excited to share a new set of Spend Permission util functions to make it easier. Check it out and let us know what you think! https://t.co/OZc1BQUcFl

[wilson.base.eth @WilsonCusack]

Cool interactable demo from @felixzh_eth to help build an intuition for Sub Accounts https://t.co/x0jQTDmZ6h

[Montana Wong @Montana_Wong]

Since launching Sub Accounts for Coinbase Smart Wallet at ETHDenver, we've been exploring ways to simplify the dev experience -- making it as easy as just adding a few lines to your app's config

Here's a quick vid on how to set this up in wagmi!

Smart Wallet Sub Accounts make Base simpler

These new features give onchain apps the ability to have less wallet popups, more fine-grained spend limits, and all the benefits of having one universal account

[Felix Zhang @felixzh_eth]

🚀 New in coinbase/wallet-sdk 4.3.0: Dapps can now request to sign transactions w/o wallet connection upfront!

Just call wallet_sendCalls when needed w/o requesting eth_requestAccounts—perfect for 1-click e-commerce checkout! 🛒⚡ #Web3 #Ecommerce #Base
