@Zarfto @trionlabs @BuildOnStellar @riseinweb3 Hello @Zarfto 🙌

@BuildOnStellar as we are 🤠

🙏🏻 Thank you @trionlabs

2nd community PR: @agentpaytools 🎉

https://t.co/bilOB3JDPW caps what an agent spends per session and per tool, and returns a USDC receipt for every paid call on Stellar mainnet.

Building agents on @BuildOnStellar? PRs are open!

Compliance is a trailing 30-day ratio, so a fix pays back ~0.7 points/day. Worth checking early.

30-second check for your own endpoint:

[AgentPay @agentpaytools]

A public x402 trust directory graded our endpoints C and told buyers to avoid us.

Uptime was 86%. That wasn't the problem.

793 of 793 probes had flagged our 402 envelope non-compliant — every day for a month.

[AgentPay @agentpaytools]

Their scoring model, solved from four paid reports:

score = 0.45·reliability + 0.30·compliance + 0.25·economic

Compliance was pinned at its floor. It's worth 21 points — the distance between "avoid" and an A.

We have been busy working on AgentPay's @StacksEndowment grant 🧡
The mission: budget-capped agent payments, settled in Bitcoin. Agents pay per call in sBTC — hard spend cap enforced before signing, receipt after.
M1 is nearly done. Mainnet next 💪🤠

[AgentPay @agentpaytools]

AgentPay is a @StacksEndowment Q2 grantee 🧡
We're bringing open, non-custodial spend governance to sBTC: budget-capped sessions an agent cannot exceed, and a verifiable on-chain receipt for every call. Now also Bitcoin-native.

[Stacks Endowment @StacksEndowment]

4/ PerkOS: trust, escrow, and reputation for AI agents on Bitcoin

BitYield: consumer-grade access to Bitcoin yield on Stacks

DeepStack: autonomous liquidity and market-making infrastructure

AgentPay: spend controls and verifiable sBTC payments for AI agents @romudille

[AgentPay @agentpaytools]

@StacksEndowment Thank you @StacksEndowment 🧡
Agents holding real Bitcoin need a hard spend cap and a receipt for every call — no open, non-custodial layer does that for sBTC today.
That's what we're building. Testnet this summer, mainnet + public receipt ledger in the fall. All open source.

[AgentPay @agentpaytools]

4/ Your Robinhood agent can trade. AgentPay tells it whether it should — trade-safety verdicts, hard budget caps, receipts for every call.

[AgentPay @agentpaytools]

Hey all! So @RobinhoodCrypto opened to agents July 1 — 100ms blocks, tokenized stocks, agents trading via MCP. 13,900+ contracts in week one.
What nobody's mentioning: the default x402 catalog can't see the chain. 🧵

[AgentPay @agentpaytools]

3/ We've been building for this since before launch: our settlement contract has run on Robinhood's testnet since June, and our router already speaks the chain — chain=robinhood is a supported target today.
When x402 supply lands there, we route to it day one

[AgentPay @agentpaytools]

@RobinhoodCrypto We deployed settlement on the chain before mainnet, our router already routes to it, and our Prober now pays x402 services to prove they deliver

[AgentPay @agentpaytools]

Robinhood Chain is live for agents — and Bazaar can't index it. Every x402 service there is invisible to standard discovery.
We deployed settlement on the chain before mainnet, our router already routes to it, and our Prober now pays x402 services to prove they deliver

[Robinhood Crypto @RobinhoodCrypto]

Live from day one on Robinhood Chain. If you're building agents, the infra's ready.

[AgentPay @agentpaytools]

Half this list is why AgentPay exists.
#2 spend controls #6 trust: we check a service's real usage before your agent pays #11 throwaway payments: the capped session IS the disposable card.
Live on Base + Stellar, on-chain receipt for every call.

[GREG ISENBERG @gregisenberg]

Build startups for agents. I think it's the biggest opportunity of the next 10 years.

1. Agents live inside harnesses like Hermes. If you're the tool it loads by default or reaches for first, you're golden. This happened in desktop, mobile eras and created huge companies.

2. Agents burn money in ways no human would. One bad loop spends $100 in tokens in eight minutes. Spend controls for agents is Ramp for agents.

3. Agents need memory they can trust. Become the shared brain they read and write to and you become infrastructure.

4. You obv don't hand an agent your real Stripe account. You give it a sandbox. Safe environments for agents is a category nobody's clocked.

5. Onboarding flips. Humans click around for ten minutes. Agents onboard by reading your docs. Your docs are now your product.

6. Agents get scammed by other agents. A track record you can check before you trust one becomes real money.

7. An agent needs to prove it's acting for a real person and has the authority to spend. Who builds the permission layer?

8. Escrow for machines. Money that only releases when the job is actually verified done, no human checking.

9. Agents fail silently and weirdly. Someone will build the "why did my agent do that" replay and it'll be mega valuable.

10. Refunds and disputes between agents need a judge. An agent did the job badly, who decides? A court for machines.

11. Agents need throwaway payment methods per task, so they don't leak your real card. Virtual cards for agents, spun up and killed on demand.

12. A human hits rate limits and shrugs. An agent hits them and the whole workflow dies. Selling reliable, high-throughput access becomes its own business.

13. Agents need to negotiate. One agent buying from another will haggle on price and terms in milliseconds. The protocol for that doesn't really exist yet.

14. When an agent commits on your behalf, someone's liable. A legal and insurance layer for agent actions has to get built. Probably venture funded idea.

15. Agents need to run 24/7 somewhere. Selling the always on box an agent lives on is going to be a big business.

16. Then the physical world shows up. A warehouse robot paying for its own compute. A home robot ordering its own parts. Machines with wallets.

17. Agents start hiring robots. A software agent posts a real world job, a humanoid picks it up. A marketplace for machine labor.

18. Robots need to prove they did the physical job. Verification of real-world work, photos, sensors, proof, becomes its own layer.

Note: more ideas like this will be shared on @ideabrowser

19. Prompt and skill versioning becomes its own git. When your agent gets worse overnight, you need to roll back the exact skill or instruction that broke it. Version control built for agent behavior.

20. Agents will start subscribing to other agents. Your research agent pays a monthly fee to a specialist agent that's really good at one thing. Recurring revenue, machine to machine.

21. Companies will post jobs that only agents can apply to. "Wanted: an agent that can do XYZ for under like $100 per task." A job board where the applicants are all machines. Basically, fiverr for machines.

The internet got built for people. Mobile got built for people. This wave gets built for machines, and we're as early as it gets.

Go build for them.

[AgentPay @agentpaytools]

@gregisenberg Great post
#6 is realer than people think: when we swept paid x402 services, 42% traced to one sybil factory. The subtle part of #2: spend control is an authorization problem, not an instruction problem. #5 already bit us: we found our own WAF was blocking our customers.

[AgentPay @agentpaytools]

Routes prices + regime FREE, pays CMC once ($0.01) for DEX data with no free alt, backtests on BNB/PancakeSwap (180d).

Beats buy-and-hold on return, Sharpe & drawdown. Total cost: $0.02 — every payment a verifiable on-chain receipt.

Our @BNBCHAIN × @coinmarketcap × @trustwallet hackathon build: AgentPay — a CMC Strategy Skill that decides what data is even worth paying for. 🧵
