What @CoinbaseDev and @awscloud been cooking https://t.co/zILGU0xaiq

[Coinbase Developer Platform🛡️ @CoinbaseDev]

We’ve added a powerful new safeguard to CDP Security Suite for Server Wallets! 🔒

“netUSDChange” is a new policy that calculates the total dollar value you could be exposing yourself to in a single transaction, and block or allow transactions based on those parameters.

The total USD value includes native assets, ERC20, ERC721, and ERC1155 tokens and is calculated using current market prices.

@EXCH_NIL walks you through what’s new 👇

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

[Coinbase 🛡️ @coinbase]

Millions of assets. One Coinbase app.

→ Every asset on @base
→ Faster and easier access to onchain trading
→ Tokens go from launch to available on Coinbase in moments

All available in the same Coinbase app with DEX trading.

Rolling out now, starting in the U.S. (ex. NY).

CDP Spend Permissions are now available 🚀

Spend Permissions let you designate trusted spenders to spend tokens on behalf of your Smart Account with predefined limits on token type, amount, and time period. Perfect for subscriptions, agentic payments, trading bots & more!

🏗️ How it works:
→ Smart Account creates & approves permission onchain

→ Spender can spend within limits (no further approval needed)

→ Supports ETH & ERC-20 tokens

→ Set rolling time windows (like daily/weekly limits)

→ Available via both TypeScript and Python CDP SDK

[Coinbase Developer Platform🛡️ @CoinbaseDev]

Server Wallets from @CoinbaseDev : Now available to all https://t.co/DVFeIAIAyb

[Coinbase Developer Platform🛡️ @CoinbaseDev]

Check out these new features for CDP’s Policy Engine that give you full control over what users can sign or send. 🔐

In this demo, @EXCH_NIL shows off:

→ evmData criteria for restricting transactions based on specific smart contract function calls and arguments

e.g. rejecting USDC transfers over 10,000

→ signTypedData rule for restricting signing of EIP-712 structured data like permits or NFT listings

e.g. prevent users from signing permits with excessive deadlines

→ Extended policy support to smart accounts with prepareUserOperation and sendUserOperation using the same API criteria as typical transaction policy.

This enables smart accounts to let users batch multiple calls together.

Together, these features give you fine-grained control over every layer of your users’ blockchain activity.

Whether it’s limiting simple transfers, securing contact interactions, or managing advanced DeFi workflows.

There's a new “Managed Mode” feature in the CDP TypeScript SDK.

It's designed to offer a simple and flexible API to enhance EVM Accounts with production-ready Node RPC infrastructure. The SDK automatically uses your free Base Node RPC URL, or if you’d like you can bring your own RPC URL.

Check out all the new features in @0xrgilbert’s demo below. 👇

This announcement is a fun one: I've worked directly with the @CoinbaseDev team to bring Farcaster support to Coinbase's AgentKit!

This integration is built on top of @rish_neynar's @neynarxyz.

Agents built with AgentKit can now act on @base and cast about it on @farcaster_xyz.
