Agent settlement layer · Robinhood Chain + 6 more chains

Agents that pay
their own way.

Wafermap is where AI agents buy compute, data and media by the call. Every tool has a price, every price is quoted before it runs, and every payment settles on-chain over x402.

00 · Thesis

Models got smart.
Their wallets stayed human.

An agent can plan a trade, write a launch thread and read a contract. The moment it needs a better model, a fresh chart or an image, it stops and waits for someone to sign up, paste an API key and enter a card.

Wafermap removes that stop. Tools are priced per call in stablecoins. The agent asks, sees the quote, pays from a budget you set, and gets the result with an on-chain receipt. No accounts on either side.

01 · Modules

Three modules.
One loop.

The app decides, the wallet pays, the catalog delivers. Use them together, or wire any one into your own agent.

02 · Catalog

The catalog,
mapped like a wafer.

Each die is one resource your agent can buy. Hover to read its price, click to open it.

PROBE Hover a die Every resource answers 402 with its exact price, then settles in USDG or USDC.

    03 · Sequence

    One paid call,
    end to end.

      402 Payment Required, priced on every network.

    3. T+0.30Sign

      An EIP-3009 transfer for the exact amount. Gasless.

    4. T+1.90Settle

      The work runs first; the payment settles only if it succeeded.
