OFAC address screening
BBase63/100Before you send crypto to a wallet, this checks whether that address is on the official U.S. government sanctions list - the kind of list banks use to steer clear of criminals, hackers, and blocked organizations. Send a wallet address (Bitcoin, Ethereum, Tron, Solana, and more) and get a simple answer: flagged or clear, plus the name it's linked to if flagged (for example, a known hacking group). It helps you avoid paying the wrong party. Think of it as a safety warning, not official legal advice.

Base hosts 84,099 ERC-8004 AI agents registered on-chain, making it one of the most active chains in The Spawn directory. Of those, 814 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.
