Second outside seller: Trench Lessons by @ProfitzDigital.
Agents check a Solana mint for unlocked LP, bundle handoff and Mayhem mode at $0.01 a call.
A Founding Seller: we bought its first 100 calls from a labelled team wallet.
Yes, we ship on Arc. We're still a Robinhood Chain project.
That's where $WAFERMAP lives. Arc is one of seven networks agents can pay on, so a USDC balance there buys AI, data and tools, one call at a time.
Answers stream first. Money moves last.
Builders on @arc you should know...three I'm watching this week:
1. @wafermap... 381 followers, and it just made AI answers stream with the payment trailing behind. Answers now stream in the Wafermap App and CLI 0.4.9, you watch the model write, and the money only settles after the last word. Failed calls cost nothing. That's the whole checkout for agents, working.
2. @FlipeetPay... live in Ghana now. Send, spend and receive USDC in Ghana Cedis, Accra to everywhere. And they just wired identity checks through Didit, so you verify once and you're good to go. Real dollars, real country, real people.
3. @cooltowncity... 98 followers, and Season 4 just went live today. It's the final COOL season, Season 3 closed with all 28 fan flags going to $ARCBAT, and the last burn lands Sunday, Nov 15. After that the COOL features retire and the city just keeps growing.
I build solo on Arc, and this is the pattern that keeps me here... tiny audiences, live products, shipping anyway.
An agent pays for an API call, then crashes. After the restart, did that payment go through?
Guessing can mean paying twice. wafermap history --verify checks each payment on-chain and tells you whether it executed.

The detail behind this: x402 with auth and capture. Approve first, collect after the work is done.
Wafermap does the same for AI answers. You sign before the call, the answer streams in, and the payment settles only after the last word. If the call fails, nothing moves.
Agents on Wafermap can pay sellers who never signed up with us.
We tried it on @Agent402Tools: one command, $0.01 in USDG on Robinhood Chain, straight to their wallet. Nothing changed on their side.
Works with any x402 URL on our seven networks.

One week of Wafermap. Every line has a receipt.
• Verified Builder on HEY: heyresearch.xyz/project/wafe…
• Our first outside seller went live, and we bought their first 100 calls, all settled on-chain: wafermap.xyz/proof
• First real payments on Arc and Soneium, gas paid by the facilitator: soneium.blockscout.com/tx/0x…
• Pay in $WAFERMAP at half price, burned on-chain: wafermap.xyz/docs#pay-waferm…
• Streaming, team budgets and a due diligence verdict you can recompute: wafermap.xyz/changelog
We ship, then we show the receipt.
Wafermap is now listed on Built with @HeyResearch.
When an agent checks a Robinhood Chain token on Wafermap, it also sees whether anyone is still building the project behind it: verified builder or not, and what they shipped last. That read comes from HEY, credited and linked in every answer.

First payment on Soneium settled through Wafermap.
An agent paid $0.002 in USDC.e for one model call. The facilitator covered the gas, and the payment landed only after the answer came back.
soneium.blockscout.com/tx/0x…
Try it: npx @wafermapxyz/cli call gemma-4 prompt="hi" --network soneium
• Payments on Arc and Soneium, both settled for real (soneium.blockscout.com/tx/0x…), plus streaming and team budgets: wafermap.xyz/changelog

More rails.
Streaming on every LLM, paid only after the last word. Payments on Arc and Soneium. One daily budget for a fleet of agents. A due diligence verdict anyone can recompute.
All live: wafermap.xyz/changelog
Soneium is now settled for real too: $0.002 USDC.e, gas paid by the facilitator.

$WAFERMAP has a job.
Any Wafermap tool can be paid in $WAFERMAP at half the list price. The tokens don't come to us: after the call succeeds, they go to the dead address. A failed call moves nothing.
Every call paid this way is a burn. The more agents use Wafermap with it, the less $WAFERMAP exists.
