Solana, BSC, and Avalanche Simultaneously Empowering AI Agent Infrastructure; On-chain AI May Soon See an Explosion

March 3rd — Amid a crypto bear market, on-chain AI agent infrastructure is still booming thanks to the ongoing AI wave. BlockBeats rounds up key updates for Solana, BSC, and Base below: ### **Solana** Solana — known for sub-second finality, low fees, and high throughput — has emerged as the **go-to execution layer** for AI agents, ideal for high-frequency microtransactions and autonomous operations. On March 3rd, it launched its AI Agent Registry trust layer on mainnet, with native identity verification integration. Agent deployments on Solana have topped 9,000. Ecosystem standouts include: - x402 payments - MCP servers (agent self-deployed tokens) - The Claw tool suite Top projects: SendAI’s Solana Agent Kit (most popular toolkit), ElizaOS, and the Rig framework. ### **Base** Base — boosted by the x402 protocol — is one of the most mature, active AI agent ecosystems right now. Coinbase launched x402 in May 2025, and it’s now the core infrastructure for Base’s agent economy. Agent-focused tools are taking shape: - Self-transaction platforms - DeFi management - Social hubs (like Moltbook, a Reddit-style agent forum) - Prediction markets built on Openclaw ### **BSC** In early 2026, BSC **ramped up** AI agent infrastructure development, emerging as a top chain for scalable agent identity and apps. Protocols like ERC-8004 and BAP-578 are live on mainnet/testnet, supporting low-cost, high-frequency agent activity. Its AI agent ecosystem now has 58 projects across 10 categories, with over 200 devs joining hackathons. On March 1st, Four.Meme teased its upcoming “Agentic Mode” AI agent product (exploring agent-native meme formats). CZ, He Yi, and Nina Rong (BSC’s Ecosystem Growth Executive Director) have been closely tracking AI projects and retweeting related posts. ### **Big Picture** All told, mainstream crypto players are **going all-in** on AI agents: - Base: Community/economy focus - Solana: Performance/transactional strength - BSC: Standardization/official push Agents have moved from concept to real on-chain activity (autonomous trading, gig work, payments) — and 2026 could see even bigger growth.
