Building a product on Solana data?
Skip the Geyser pipeline — embed KOL flow, deployer reputation, and the all-DEX firehose over REST, WebSocket, or webhooks. The Business tier (€400/mo) is the self-serve embed license at 500k calls/day — Enterprise adds white-label & redistribution.
Launched March 3, 2026, the Solana Agent Registry is an on-chain protocol giving AI agents verifiable identity, portable reputation, and trust infrastructure. Over 9,000 agents were deployed at launch.
It consists of three components:
This is Solana's answer to the question "how do you trust an autonomous agent?" — by giving it a verifiable on-chain identity and reputation score.
| Token | Description |
|---|---|
| GOAT (Goatseus Maximus) | First token endorsed by an autonomous AI agent (Truth Terminal). Reached $1B+ market cap. |
| ELIZAOS | Token for the ElizaOS framework. 7.4B circulating supply. |
| ZEREBRO | Associated with the ZerePy framework. Peaked at ~$800M market cap. |
| VIRTUAL | Virtuals Protocol. Agent Commerce Protocol for autonomous agent-to-agent transactions. |
Total AI agents crypto market cap: approximately $2.67B as of late March 2026.
AI agents are not a future concept on Solana — they're a present reality with 35M+ transactions already processed. The combination of x402 payments, the Agent Registry, and multiple development frameworks creates a full stack for autonomous AI:

MadeOnSol isn't an RPC or another generic token API — it's Solana memecoin intelligence that's painful to build in-house, pulled from dual-region gRPC shred streams: sub-second from the on-chain event to your app.
Signals you'd otherwise build
KOL & smart-money flow from 1,000+ labeled wallets, deployer reputation, coordination clusters, linked-wallet entity resolution, and an all-DEX firehose.
Embed it in your product
The Business tier (€400/mo, self-serve) licenses you to display MadeOnSol data inside your own product — 500k calls/day, 10 WS + 5 firehose connections. Enterprise above adds white-label & redistribution rights and custom endpoints.
Evaluate first, commit later
Test everything on a free ULTRA key — no commitment. If it fits, we scope volume or white-label pricing.

Developer Tools
An AI agent is only as sharp as the data it can reach. This guide compares the three ways to wire live Solana memecoin intelligence — KOL flow, rug scores, deployer reputation — into an agent: the MCP server for Claude and Cursor, the solana-agent-kit plugin for autonomous JS agents, and x402 micropayments where the agent's wallet IS the API key. With the decision table, code-free setup for each, and the safety line that matters: the data layer never executes trades.
API Guides
A walk-through of wiring an autonomous AI agent to MadeOnSol's x402 endpoints. The agent pays $0.005 USDC per KOL trade lookup from its own Solana wallet — no API key, no signup, no monthly subscription. Production-ready in under 20 lines.

Open the KOL TrackerSolana now processes 65% of all AI agent payments on-chain. With 35 million+ x402 transactions and $16.4 million in volume, the network has become the default settlement layer for autonomous AI. This guide covers what x402 is, how it works, which frameworks developers use, and what this means for the Solana ecosystem.
x402 is an open payment protocol developed by Coinbase that revives the long-dormant HTTP status code 402 ("Payment Required") to embed stablecoin payments directly into standard HTTP requests.
No API keys. No subscriptions. No human intervention. The AI agent pays per-request with USDC and gets what it needs.
| Metric | Value |
|---|---|
| Launch date | May 6, 2025 (V1); December 11, 2025 (V2) |
| Solana transactions (cumulative) | 35M+ |
| Solana volume (cumulative) | $16.4M+ |
| Solana share of all agentic payments | 65% |
| Peak week | 6.8M transactions (Dec 22, 2025) |
| Unique seller wallets (Solana) | 25,000+ |
| Unique buyer wallets (Solana) | 18,000+ |
| Supported chains | Solana, Base, Ethereum, Polygon, Stellar |
The x402 Foundation was established in September 2025, co-founded by Coinbase and Cloudflare. Members include Google and Visa. Cloudflare integrated x402 into its Agents SDK and MCP servers.
Important context: More than 78% of peak-period transactions were classified as non-organic activity. Weekly volume fell from 6.8M to under 510K between December 2025 and February 2026 — a 90%+ decline. The protocol is real and growing, but transaction counts should be interpreted carefully.
Three factors make Solana the natural fit (for a broader primer on what these agents are and the best projects building them, see our Solana AI agents guide):
The Solana Foundation is actively positioning the network as core infrastructure for what they call the "agentic internet." Foundation CPO Vibhu Norby predicts that "99.99% of all on-chain transactions in 2 years will be driven by agents, bots, and LLM-based wallets."
The most popular open-source framework for autonomous AI agents. Created by Shaw Walters, ElizaOS is a TypeScript-based agent operating system with 17,600+ GitHub stars and 200+ plugins.
Connects AI agents to 30+ Solana protocols with 60+ pre-built actions: token swaps, NFT minting, staking, lending, and more. Integrates with LangChain, Vercel AI SDK, and ElizaOS.
The fastest way to give an LLM-based agent the ability to interact with Solana DeFi.
Whether AI agents will account for "99.99% of all transactions" as the Solana Foundation predicts remains to be seen. But the infrastructure is live, the frameworks are mature, and the transaction data shows real — if volatile — adoption.
x402 is an open payment protocol that uses the HTTP 402 status code to embed USDC payments into standard web requests. On Solana, AI agents use x402 to pay for APIs, data, and compute resources autonomously — no API keys, subscriptions, or human intervention required. The protocol has processed 35M+ transactions on Solana.
AI agents on Solana use frameworks like ElizaOS and Solana Agent Kit to interact with DeFi protocols, execute trades, manage portfolios, and make payments. Solana's low fees (~$0.00025 per transaction) and fast block times (400ms) make it economically viable for agents making hundreds of daily transactions.
The Solana Agent Registry is an on-chain protocol launched March 3, 2026, that gives AI agents verifiable identity, portable reputation, and trust infrastructure. It launched with 9,000+ agents and provides identity, reputation, and validation registries.
