Payouts.com co-founders Leor Ceder and Barak Hirchson argue the next wave of AI-driven commerce will run on stablecoin rails — but the real enterprise value will live in the programmable control layer that governs them, not in wallets alone.
Why stablecoins? Juniper Research estimates cross-border B2B stablecoin payments could explode from $13.4 billion in 2026 to $5 trillion by 2035, with B2B taking 85% of total stablecoin transaction value. Hirchson, Payouts.com’s chief solutions officer, says rail choice ultimately depends on recipient country, payment method, urgency, size and cost — and in many cases stablecoins are the clear winner. He points to two sweet spots:
- Cross-border vs. SWIFT: traditional wires can lose 4–5% to fees and FX spreads, making stablecoins far cheaper.
- Machine-to-API micropayments: the x402 standard already routes pay-per-call API invoices in stablecoin. Crypto.news reported AI agents have settled $73 million across 176 million transactions on crypto rails, with USDC handling 98.6% of that activity.
But wallets are only the foundation. “PIX clears in under ten seconds in Brazil for free, UPI handles hundreds of millions of transactions a day in India at near-zero cost,” Hirchson noted. “The agents that scale are the ones that can pick the right rail per transaction, not the ones locked into a single rail based on what their limited wallet supports.”
More important, he says, is the programmable control layer that enforces enterprise policies. Hirchson lists five non-negotiable controls companies should require before allowing agents to transact autonomously:
- Scoped credentials tied to specific capabilities
- Hard spend caps enforced at the protocol level
- Cryptographically signed mandates
- Idempotency at the payment layer to prevent duplicate charges
- A fail-closed posture so systems stop rather than risk unauthorized spending
“This is what programmable spending actually means,” he said. “You define the envelope once, the infrastructure enforces it forever, and the agent operates freely inside it.” He warns some wallets still ship with only an API key and a balance — “the worst-case configuration for a compromised key” — while others already include hard caps and signed mandates.
Ceder frames the debate not as a race for which stablecoin wins, but over programmability. By mid‑2027, he predicts, the critical differentiator will be how granularly enterprises can specify agent permissions, how reliably policies are enforced, and how cleanly compliance can be proven afterward. “The wallet wars happening right now will look the way the browser wars look in retrospect: necessary, formative, and not where the durable value got captured,” he said. He argued that the compliance layer must be embedded in the infrastructure so every payment runs through principal, account and jurisdiction checks before money moves.
Industry momentum is aligning around new rails and standards. Coinbase and Cloudflare have incorporated the x402 protocol into a fast-growing settlement rail for agents; x402 recently joined the Linux Foundation. AWS embedded x402 into Amazon Bedrock AgentCore Payments this month, and Solana and Google launched Pay.sh as a parallel route.
Payouts.com’s bet is clear: agents should remain autonomous, but enterprise spend will be captured by the control layer sitting above stablecoin rails. The envelope around the agent — not the agent itself — is where durable value will land.
