Base Batches Messaging Buildathon

We’re stoked to add a dedicated messaging buildathon as part of Base Batch 001.

Builders interested in driving the future of messaging on Base can jump in and get started building.

Overview

Messaging presents a huge opportunity for Base builders. Messaging is the largest use-case in the world, but it’s more than just conversations—it’s a secure, programmable channel for financial and social innovation. When combined with the onchain capabilities of Coinbase Wallet, builders have a new surface area to build 10X better messaging experiences not currently possible on legacy platforms like WhatsApp or Messenger.

Secure group chats & DMs are the new surface area for developers.

Coinbase Wallet & XMTP are bringing AI + crypto + mini apps into secure messaging to unlock use-cases never before possible.

This could include:

• AI Agents that trade, swap, bridge and more.
• Group chats with tokens and micro-economies.
• Mini-app games you play with friends in group chats

There are so many powerful things you can build...

This is your chance to get noticed, get funded, and get the support you need post-buildathon to bring your idea to market.

THE PROMPT

Simple. Build the next killer agent or messaging mini-app.

FOCUS AREAS

We’ve provided the following 5 areas to help focus your energy on where to start building agents for messaging.

• Utility Agents - Messaging meets productivity. Create agents that help groups plan events, split payments, manage shared wallets, or track action items. DMs and group chats become the new coordination layer with an agent powered by financial rails.
• Trading and DeFi Agents - Build agents that manage your portfolio, track trending tokens, notify a group chat of price actions, and help a user to rebalance holdings. Whether it's a DM or group chat experience, create an agent with serious knowledge of how to help a degen out.
• Agent and Mini App Interaction - Build a creative way for an agent to utilize mini apps. Your agent could launch a mini app directly inside a group chat for a multiplayer game, or use a mini app for visualizing a recent poll. Anything goes, bring the power of mini apps to the chat experience.
• Gaming Agents - Create an agent that facilitates a game in a group, this could be a known game like “Guess Who” for an icebreaker experience, or an agent sharing score alerts in a group chat.
• Social Agents - Build an agent that makes group chats more fun, interactive, and engaging. This could be dropping in curated content for the group, or an agent that helps people match for meetups, share recommendations, and rewards users for posting their recs!
