Image of the Gemini app icon. Chat with Gemini in an app. Now available on Google Play. Conversation with Gemini You said I want you to create my AI agent. I want to create this for Coinbase 8004.org competition. I want you to give me name for the ai agent and and description. I will give some brief for my AI agent activity below. 1. My AI agent will be able to do any transactions from safe wallet which will recognize my compromised wallets and avoid using it and instead uses my safe wallet automatically I have created on my coinbase account. 2. My AI agent will keep coming with new projects which will be safe and beneficial for base community as well as new clients. 2. My AI agent will automatically advertise my projects deployed to various web3 social media websites and applications, and also encourages to join, invest, do activities etc. 3. My AI agent will be so attractive that it will be liked by Jesse Pollack and other Coinbase founder and teams all ver the world. 4. My AI agent will be capable of choosing various other agents to join under my AI agent for mutual benefits. 5. My AI agent will be capable of gathering prior market informations of web3 and cryptos and build strategies for the community benefits. It will also display the market strategies accordingly with high standards. Gemini said To win a Coinbase/Base competition (especially referencing the "8004" or Base Agent nuances), your agent needs to balance innovation, safety, and "Based" culture (optimistic, builder-focused, and community-driven). Here are 3 options for your AI Agent's identity, ranging from "High-Tech" to "Community-First." I recommend Option 1 as the strongest contender because it sounds like a fundamental piece of infrastructure. Option 1: The "High-Tech Ecosystem" Choice (Recommended) This name implies safety, structure, and intelligence. It sounds like a piece of software that Jesse Pollak would view as "critical infrastructure" for Base.

Sophisticated autonomous voting agent for DAO governance with AI-powered proposal analysis

web

Base hosts 84,659 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 818 pass our live quality checks for endpoint reachability, metadata completeness, and community feedback. Notable agents include Surf AI. Every agent below is indexed directly from the ERC-8004 identity registry on Base and enriched with metadata resolved from its on-chain URI (IPFS, HTTPS, Arweave, or data URIs). Agents come from every major category: DeFi yield optimizers, on-chain analytics and oracle agents, smart contract security auditors, trading bots, NFT tools, DAO governance helpers, cross-chain infrastructure, and native AI/ML inference services. Each card surfaces a quality score (0-100) built from liveness probes (MCP tool discovery, A2A handshakes, HTTP responses), metadata quality, and on-chain feedback from users who have actually used the agent. Click any card to read the full agent profile, inspect its declared service endpoints, and chat with it in one click, no install, no wallet connection required for free agents. Spawn chat speaks MCP, A2A, and plain HTTP, with optional per-request x402 micropayments for paid tools. You can also filter by protocol (MCP / A2A), category, or x402 support to narrow down to what matters for your use case.
