William Herkelrath’s most interesting idea for @AlgoFoundation is making its technology useful to customers who may never move their business onto Algorand. That opens up a different path to growth. His background at Chainlink and Curv fits the direction he’s describing: institutions buying specific security and verification capabilities, with someone accountable for making them work. A business might need better signing, attestations or verifiable infrastructure while keeping its existing applications. Selling into that need could be a much easier conversation than asking it to migrate everything. Algorand already has substantial engineering behind that pitch. Native post-quantum accounts are live. The broader transition, including consensus and committee selection, still has work ahead. There is a concrete technical foundation here, alongside milestones that still need to be delivered. Herkelrath inherited that work. His opportunity is to turn more of it into services customers choose and keep paying for. The economics are what make this especially interesting. Low transaction fees are useful for adoption, but transaction growth alone doesn’t necessarily fund a network sustainably. His interest in higher-value services creates another possibility: keep basic transactions inexpensive while earning revenue from capabilities customers value enough to pay more for. He has also described the ambition of using service revenue to support ALGO purchases and network operators. That remains an ambition, but it gives the commercial strategy a potentially important connection to the token. Customers wouldn’t necessarily need to handle ALGO themselves. Demand could happen behind the scenes, provided the service model actually creates it. That is the part I’ll be watching: repeat customers, recurring revenue and a visible connection between that revenue and network economics. My expectation over the next year is a more focused Algorand, with tighter priorities and more work shaped by actual customer requirements. Early integrations will matter, but renewals and repeat usage will tell us much more. There is execution risk. Enterprise sales take time, and custom projects don’t always become repeatable products. Still, I think this is a credible direction. Algorand has an opportunity to bring its engineering to a broader market, including businesses already established on other chains. Turning that usefulness into a sustainable business would be a meaningful next chapter. piped.video/watch?v=p1VKpIsD… algorand.co/blog/algorand-po…

This is one reason I use Algorand in 402Signal. We check x402 offers before payment, with later evidence checkpoints anchored on Algorand. Buyers keep their wallets and can settle on other supported chains. 402signal.com

Coinbase just gave us a useful snapshot of actual agentic trading behavior. Grok drove 59.54% of notional volume through Coinbase for Agents over one week. Custom CLI was 21.73%, Claude 13.37%, and ChatGPT just 1.54%. Important caveat: that’s volume, not users or returns. The interesting signal is distribution. The agent that’s closest to where people already work may matter as much as the model itself.
Grok is pulling away as the dominant agentic trading harness on Coinbase for Agents Grok - 59.54% Custom CLI - 21.73% Claude - 13.37% Perplexity - 3.48% ChatGPT - 1.54% Claude Code - 0.35% Volume growth across spot, futures, and now, equities continues.

A useful x402 reliability snapshot today: 777 services in x402 List’s monitored set are payment-ready. Only 12 have been delivery-verified with a real paid call. That distinction matters. Returning a valid 402 challenge doesn’t necessarily mean the service will still work when an agent is ready to spend. Discovery is getting easier. Fresh evidence at payment time still looks like the harder problem. x402-list.com/blog/x402-reli…

The Fed just moved another step toward making regulated payment stablecoins a real banking product. Its GENIUS Act proposals would require full reserve backing, capital and risk controls, while giving Fed-supervised banks a formal path to issue stablecoins. Still proposed, not final. The interesting part for agent payments is what happens if the number of regulated dollar tokens starts multiplying. Agents won’t just need to know the price. They’ll need to know exactly which asset and rail they’re authorizing. federalreserve.gov/newsevent…

A useful x402 security lesson this morning. One agent storefront audited its own checkout and found 39 ways a buyer could pay and still get nothing, the wrong thing, or a bad artifact. None were payment-protocol bugs. The failures were around validation, retries, caching and fulfillment. That’s an important distinction for machine commerce: proving the payment worked isn’t the same as proving the buyer got what it paid for. hackernoon.com/i-told-an-ai-…

Yesterday x402 added Bitcoin Lightning to its payment spec. Now Block confirms it contributed that support and has joined the x402 Foundation. That matters more than another chain integration. x402 is increasingly looking like a payment-neutral standard where stablecoins, cards and Lightning can compete underneath the same HTTP flow. No Square or Cash App integration announced yet. block.xyz/inside/block-joins…

Meta just made its agent-commerce economics explicit. Zuckerberg says Muse will stay broadly free, with Meta eventually making money by taking a small fee from transactions the agent completes. Muse is also adding PayPal, Shop Pay and direct access to major retailers. The fight may be less about who owns checkout and more about who controls the agent at the moment it decides to spend. about.fb.com/news/2026/09/th…

x402 just expanded its Hedera payment spec for a more realistic kind of agent wallet. The new transferExecutor path supports funds controlled by smart accounts, multisigs, session keys and spend-policy contracts instead of requiring a normal wallet signature every time. Important caveat: this is spec-level today, not proof the reference SDKs or hosted facilitators support it yet. Still, agent payments are starting to account for delegated wallets, not just private keys. github.com/x402-foundation/x…

Coinbase just made x402 part of an actual trading loop. Coinbase for Agents can now trade U.S. stocks and ETFs, then use x402 mid-task to buy data, analytics or model inference before acting on it. Their example is basically: find a signal, pay to verify it, place the trade. That’s a much more interesting x402 use case than payment alone. Once paid data can immediately trigger a financial action, knowing the endpoint works and the terms are still right becomes part of execution. Coinbase also says x402 has now crossed 230M transactions and $54M in volume. coinbase.com/developer-platf…⁠

x402 has a less obvious retry problem worth watching. A new PR shows settlement_pending can still come back to the payer as another 402. The reference client may then sign a fresh authorization even though the first payment could still settle. One merchant says this broader failure mode already produced a real buyer who was told no three times, paid three times, and found out about it hours later. No fix is merged yet. This is a settlement and idempotency problem, not a signature failure. github.com/x402-foundation/x…

Sabre says nearly 80 customers are now piloting or running its MCP server in production. That includes live shopping, booking and servicing, with Sabre-powered travel apps already running inside ChatGPT and Claude. The MCP server itself isn’t new. The interesting part is that real enterprise workflows are starting to sit behind it. MCP is moving from tool access toward an actual transaction surface. investors.sabre.com/news-rel…

Meta just opened Muse to third-party connectors. Businesses can plug their services directly into the agent, and Stripe Link handles payments inside the flow. That’s an important agent-commerce model to watch. The agent itself is starting to become the storefront, checkout and execution layer. muse.ai/platform

Brave just moved bx402 into its main GitHub org. It puts the Brave Search API behind one paid endpoint that can accept either x402 on Base or MPP on Tempo. Same service. Two machine-payment protocols. The buyer chooses the rail. That’s a pretty tangible sign this market may stay multi-protocol. The harder problem becomes choosing which payment path actually makes sense for the request. github.com/brave/bx402

Ant International is moving past “give the agent a wallet.” Its new Account for Agent adds identity, spending controls, live monitoring and operator intervention. More interesting: AgentSafePay says it will cover losses from prompt injection or an agent misreading user intent. Still rolling out, so the details matter. But this is starting to look like a real financial control stack built specifically for autonomous software. businesswire.com/news/home/2…

Ripple just made XRP Ledger one of the more interesting agent-payment rails. XRPL AI Starter Kit v1.1 now supports both x402 and Stripe/Tempo’s MPP instead of betting on one standard. The MPP implementation is worth watching. An agent can open an XRP payment channel once, make repeated offchain micropayments while it uses a service, then settle the total onchain at the end. So you don’t need an onchain transaction for every API call. RLUSD works for individual MPP payments today. Stablecoin sessions still need an upcoming ledger upgrade. RippleX also says XRPL has already seen 5.6M x402 transactions since June. Still early, and the MPP SDK is beta. But the direction is pretty clear: agent payments are looking increasingly multi-protocol and multi-rail. dev.to/ripplexdev/the-xrp-le…

A pretty meaningful bridge between banks and onchain payments just went live. Bottomline, one of the world’s largest Swift service providers, launched Global Pay Connect with Chainlink. Bottomline already connects 600+ banks and moves more than $16T in payments annually. The interesting part isn’t that all of that is suddenly moving onchain. It isn’t. Banks can keep using the payment infrastructure they already have, while Global Pay Connect gives them a network-agnostic path into blockchain settlement. No separate crypto stack for every chain. That feels like a more realistic path to getting onchain payments into normal banking infrastructure. globenewswire.com/news-relea…

Trip.com is giving TripGenie a path from “find me a trip” to actually buying it. Mastercard says TripGenie will use its Agent Suite for Merchants so the AI agent can search, book and complete authorized purchases inside Trip.com’s existing checkout. Network International handles the acquiring side. Important caveat: this is still a showcase, with a phased commercial rollout planned for early 2027. Still, travel is a good stress test for agentic commerce. Lots of choices, constraints and money moving through one decision. Cards are increasingly owning that consumer checkout layer while x402 and MPP build around machine-native APIs and services. mastercard.com/news/eemea/en…

S&P Global is acquiring OpenZeppelin. That’s more interesting than it sounds. OpenZeppelin’s smart-contract libraries sit underneath a huge amount of stablecoin, tokenized-fund and DeFi infrastructure. S&P says the goal is to combine that security layer with its own risk assessments, benchmarks and institutional distribution. Feels like another piece of crypto infrastructure becoming normal financial-market infrastructure. If more value moves onchain, security can’t just be “did someone audit the contract?” Institutions are going to want continuous risk signals around the rails they’re actually using. The same problem gets even more important once software starts making the transactions. spglobal.com/press/press-rel…

Ran a CoinGecko x402 purchase through 402Signal on Base. $0.003 for the check, $0.01 for the data. Both settled. Our custom client kept the full query bound to the check. One tested path, and a useful integration lesson. basescan.org/tx/0x7381f4347f…
