Get Your App Ready for April 9 Starting April 9, the Base App supports all standard web apps, not just mini apps. If you've been building on the Farcaster mini-app spec, there are a few things to do before the cutover. The quick gut check: does your app work in a mobile browser with a connected wallet and no Farcaster context? If yes, you're good. We covered the full scope of changes in our earlier post. Three things to check off, and where to go if you need help. 1. Register on Base.dev If you haven't already, create a project at Base.dev and fill in your app metadata. This is how the Base App surfaces your app for search and discovery. If you registered previously, your metadata has already been backfilled and you don't need to do anything here. 2. Switch to Sign-In with Ethereum The Farcaster SDK signIn method won't work in the Base App after April 9. The replacement is SIWE (Sign-In with Ethereum) using wagmi and viem. Your app authenticates through the connected wallet address instead of a Farcaster identity. This is the biggest change for most builders. The migration docs walk through the full setup with code examples. 3. Audit your Farcaster SDK usage If you're using other Farcaster SDK the migration docs include a full compatibility table with the replacement for each method.


Last week, we shipped new docs for AI agents. This includes: - mock demos - wallet guides: @bankrbot @CoinbaseDev @paysponge - x402 data endpoints: @Alchemy @nansen_ai - swaps and trading guides (s/o @jonroethke ) - builder codes for agents (s/o @sohey_eth ) link below 👇

Excited to share that Ramp Stablecoin Accounts are now in public beta. Ramp customers can now: 1. Hold stables on Ramp 2. Earn rewards on stable balances 3. Pay vendors & employees worldwide in USDC 4. Pay off Ramp Card + USD payments using stables 5. Use one system for both fiat + stable obligations with the same approvals, controls, and accounting We are bullish on the institutional adoption of stablecoins and to bring stable technology to Ramp customers.

Coinbase rebuilt their engineering workflows around agents. Linear is where those agents go to understand what needs to be done. → linear.app/customers/coin…

Building on Base just got easier. Our upgraded docs now work with your AI agents and here's how!
