I just realized that AI Agent infrastructure on the blockchain has developed very rapidly across the three main ecosystems. Although the market is still in a bear condition, progress in this sector doesn't stop.

Solana has become the main choice for AI Agent execution layer due to its sub-second speed, low costs, and high throughput—perfect for high-frequency microtransactions and automated operations. They launched the AI Agent Registry on mainnet in early March with native authentication integration. Deployment of agents on Solana has exceeded 9,000, focusing on payment x402, MCP servers, and Claw tools. Projects like Solana Agent Kit from SendAI, ElizaOS, and Rig have become popular frameworks in the ecosystem.

Base chain attracts my attention because of its x402 protocol, which serves as the backbone of the agent economy there. This protocol was launched last year and is now very mature as an AI Agent ecosystem. Derivative applications from Openclaw such as automated trading, DeFi management, social apps ( similar to Reddit forums for agents called Moltbook), and prediction markets are starting to develop on this base chain.

Meanwhile, BSC is also not lagging—since the beginning of this year, they have been pushing AI Agent infrastructure with protocols like ERC-8004 and BAP-578, which are already live on mainnet and testnet. The AI Agent ecosystem on BSC has grown to 58 projects across 10 main categories, attracting over 200 developers at the hackathon. Four.Meme even announced a new AI Agent product called "Agentic Mode" in early March to explore native Agent Meme forms.

What’s interesting is that each ecosystem has a different focus: Base chain emphasizes community and economicization, Solana focuses on performance and transactional speed, while BSC tends toward standardization and official push. AI Agents have moved from concept to real activity on the blockchain—automated trading, hiring mechanisms, payments—all are operational. I predict AI on the blockchain will boom this year.
