The landscape of AI agent payments is shifting beyond simple wallet solutions. According to Payouts.com co-founders Leor Ceder and Barak Hirchson, the real future lies in combining stablecoin payment rails with a programmable control infrastructure designed for enterprise reliability. While wallets are essential building blocks, the lasting business value resides in what governs them.
This viewpoint challenges the prevailing narrative that wallets alone dominate agent payment conversations. Juniper Research predicts that cross-border B2B stablecoin transactions will skyrocket to $5 trillion by 2035, a dramatic increase from $13.4 billion projected for 2026, with B2B transactions accounting for 85% of all stablecoin activity.
Hirchson emphasizes that choosing the right payment rail depends on the recipient’s location, preferred method, urgency, amount, and cost. Stablecoins excel in two key areas: international transfers, where SWIFT fees and FX spreads can consume 4–5% of the transaction value, and machine-to-API micropayments using the x402 standard for pay-per-call invoices. Already, AI agents have settled $73 million through 176 million crypto transactions, with USDC dominating at 98.6%.
Local payment systems like Brazil’s PIX and India’s UPI offer free or near-zero cost processing, handling massive volumes daily. Hirchson argues that successful agents will be those capable of selecting the optimal rail per transaction rather than being restricted to a single rail based on limited wallet capabilities.
To enable safe autonomous agent transactions, Hirchson identifies five critical controls: scoped credentials, protocol-level hard spend caps, cryptographically signed mandates, payment-layer idempotency, and a fail-closed security posture. He explains that programmable spending means defining the rules once, after which the infrastructure enforces them, allowing the agent to operate freely within boundaries. However, industry adoption of these controls is uneven, with some wallets incorporating hard caps and signed mandates, while others merely provide an API key and a balance—a configuration that poses risks if the key is compromised.
Looking ahead to 2027, Ceder predicts the focus will shift from stablecoin selection to programmability. Enterprises will care about how precisely they can define agent permissions, how reliably those policies are enforced, and how easily compliance can be verified afterward. He compares the current wallet competition to the browser wars—necessary but not where enduring value accumulates. The compliance layer must be embedded in the infrastructure rather than the agent, ensuring every payment undergoes checks on principal, account, and jurisdiction before execution.
Notably, Coinbase and Cloudflare have integrated the x402 protocol into a growing settlement network for agents, now supported by the Linux Foundation. AWS recently incorporated x402 into Amazon Bedrock AgentCore Payments, while Solana and Google introduced Pay.sh as an alternative. For Payouts.com, the strategic bet is that the control layer above these rails will capture the enterprise spend, keeping agents autonomous while the governing envelope remains fixed.
