Where Robinhood Chain Data Comes From: Our Own Node, a Non-Custodial Facilitator, No Reseller

Accuracy in on-chain data is a provenance question. Here's the full chain of custody behind MadeOnSol's Robinhood Chain API: our own synced node, a self-hosted non-custodial x402 facilitator, and no third-party reseller in the middle.

Building a product on Solana data?

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 2,000+ labeled wallets, deployer reputation, coordination clusters, linked-wallet entity resolution, and an all-DEX firehose.

Does x402 Only Work with USDC? USDG, EIP-3009 and Robinhood Chain Explained

A common myth says x402 payments only work with USDC. They don't. USDG (Global Dollar) implements EIP-3009, so it works with x402 today — and it settles natively on Robinhood Chain. Here's why, with the on-chain details.

How AI Agents Pay for Robinhood Chain Data in USDG (x402, No API Key)

AI agents can now buy Robinhood Chain KOL and deployer intelligence per call — no signup, no API key, the wallet is the key. Here's how the x402 payment flow works, and why you can pay in USDG on Robinhood Chain or USDC on Solana.

3. A non-custodial payment rail

The same principle carries into how agents pay for the data. Robinhood Chain endpoints are available keyless via x402, settling in USDG — and that settlement is non-custodial.

When an AI agent pays, it signs an EIP-3009 transferWithAuthorization: a signature that authorizes exactly one transfer, of the exact amount, to exactly our receiving address. Our self-hosted facilitator broadcasts that authorization and pays the gas — but it cannot change the amount or the destination, and it never takes custody of the agent's funds. The USDG moves wallet-to-wallet directly. We run the facilitator ourselves, on our own node, so that leg has no third-party dependency either.

So the whole path — read the chain from our node, compute the signal, sell it over a facilitator we operate — has no reseller and no custodian in it.

Why this is hard to copy

Provenance is exactly what a reseller or a generic "x402 echo" endpoint can't claim. Anyone can proxy an upstream feed; only an operator running its own node and its own facilitator can promise there's nothing in the middle. And the cross-chain piece — the Solana KOLs we already track, traced onto their Robinhood Chain wallets — depends on data we own on both chains, so it isn't reconstructable by a Robinhood-Chain-only tool.

If you want the historical-completeness side of provenance — genesis-complete Robinhood Chain history indexed from block zero — that's covered separately in The Robinhood Chain Dataset, From Genesis. This piece is about the live API and its payment rail.

Every Robinhood Chain endpoint returns the settlement transaction in a response header, so you can verify on-chain that your payment settled and where. Start with the free discovery endpoint:
