In the fast-paced world of blockchain and AI, innovations that bridge everyday tasks with crypto are always exciting. Recently, Aryan from SendAI shared a cool update on X (formerly Twitter) about enhancing the x402-MCP protocol to support Solana. This move not only expands the tool's capabilities but also showcases practical use cases, like ordering books from Amazon using crypto. If you're into meme tokens, this could be a game-changer for projects like SENDAI and PAYAI, as it paves the way for more autonomous AI-driven transactions.

What Went Down in the Tweet

Aryan, tweeting from @_0xaryan, announced that the team at SendAI has improved x402-MCP to include Solana support. To demonstrate, he ordered Chris Dixon's book "Read Write Own" from Amazon using the updated protocol along with Crossmint on Solana. Originally released via Vercel with only Base chain support, this upgrade opens up faster and cheaper transactions on Solana's high-speed blockchain.

He gave a shoutout to @PayAINetwork for facilitating the process and linked to the improvement pull request on GitHub: https://github.com/ethanniser/x402-mcp/pull/2. The video attached to the tweet walks through the demo, showing an AI chat interface handling the order seamlessly with USDC payments.

Breaking Down x402-MCP

If you're new to this, x402 is an open payment protocol developed by Coinbase that allows instant stablecoin payments over HTTP, using the "402 Payment Required" status code. It's designed to make micropayments easy and automatic. MCP, or Model Context Protocol, is a way for AI models to interact with external tools securely.

x402-MCP combines these to enable paid tools within AI applications. Think of it as giving AI agents the ability to pay for services or actions on the fly. On the server side, developers can create paid handlers; on the client side, it integrates payments into AI streams. Technologies like Zod for validation, AI SDK for streaming, and now Solana integrations make it robust.

The pull request, contributed by @thearyanag (likely Aryan himself), adds Solana compatibility while keeping EVM chains supported. It includes new imports from @solana/kit, type-safe overloads, and an example app that switches networks based on environment variables. This means AI agents can now operate on Solana's ecosystem, known for its speed and low fees, making it ideal for meme token communities where quick trades and interactions are key.

The Demo: Ordering from Amazon with Crypto

In the video, Aryan shows a ChatGPT-like interface powered by GPT-4o. He copies the Amazon product link for "Read Write Own," pastes it into the chat, and asks the AI to order it. The AI confirms the price (around $16.20), generates a payment authorization for USDC on Solana's DevNet, and completes the purchase via Crossmint. The book is set to arrive by October 26th—talk about blending web2 shopping with web3 payments!

Crossmint here acts as the bridge, handling the fiat-to-crypto conversion or direct crypto payments. This demo highlights how x402-MCP can make AI agents more autonomous, handling real-world tasks without human intervention after initial setup.

Why This Matters for Meme Tokens

SendAI isn't just about tech; it's tied to the SENDAI token (contract: CSmVx8guiujGZuLovb91Ft5TLi8td3iprMY8LBdYpump), a Solana-based meme token with a market cap around $13K as of late October 2025. SendAI provides toolkits for AI agents on Solana, including actions like token swaps and deployments using natural language. This update could supercharge SENDAI by enabling AI-driven payments within the meme ecosystem.

Similarly, PayAI Network, with its PAYAI token (contract: E7NgL19JbN8BhUDgWjkH8MtnbhJoaGaWJqosxZZepump), focuses on decentralized AI agent marketplaces. Priced at about $0.009 with a higher liquidity pool, PayAI emphasizes autonomous transactions between agents. As an x402 facilitator, they're perfectly positioned to leverage this Solana support for smoother, agentic commerce in the meme space.

Imagine meme token communities using AI to automate buys, sells, or even merchandise orders—all paid via Solana. This reduces friction and could boost adoption, making meme tokens more than just speculative assets.

Looking Ahead

This development from SendAI underscores the growing intersection of AI, blockchain, and everyday e-commerce. For blockchain practitioners and meme enthusiasts, it's a reminder to keep an eye on projects like SendAI and PayAI Network. If you're building on Solana, check out the updated x402-MCP repo and experiment with your own AI agents.
