Audit & Compliance for x402

Sentinel is the compliance layer for x402 agent payments, enforcing limits, logging every transaction, and enabling enterprise-grade oversight.

A New Financial Primitive

Valeo is not just an app. It’s a full ecosystem: the Valeo iOS client, the v402 execution + payment protocol, and $UAID, a stablecoin designed for AI agent payments.

.01

Integrate in minutes

Capture payment intent

Drop v402 into any API. Add paid endpoints without building billing, auth, or escrow.

Every x402 payment is captured with structured metadata, who initiated it, what endpoint was called, and under which capability.

.02

Execute with guardrails

Verify execution

Capability-scoped intents, allowlists, and spend limits, built for autonomous spending.

Replay-safe receipts and deterministic verification ensure that payments and outcomes can be independently validated.

.03

Settle with proof

Export for compliance

Replay-safe receipts and on-chain verification. Same intent = same outcome.

Structured logs and verifiable payment trails make agent spending reviewable, reportable, and enterprise-ready.

"The agent economy needs more than payments. It needs verifiable execution, enforceable compliance, and native liquidity.
With v402, Sentinel, UAID, and our iOS app, we’re building that full stack."

Frequently Asked Questions.

Simple answers to what most teams ask before joining Probe.

What is Valeo?

Valeo is the AI-native financial stack on Solana — combining a non-custodial iOS app, the v402 agent payment protocol, and the $UAID stablecoin designed for autonomous payments.

Is Valeo live?

Yes. The Valeo iOS beta is live and publicly accessible. We’re shipping weekly updates and expanding features across agents, payments, and cards.

What is v402?

v402 is our payment protocol for AI agents. It introduces capability-scoped payment intents, replay-safe receipts, and proof-of-execution flows — enabling agents to pay and settle securely at internet scale.

How is v402 different from x402?

x402 is a strong concept — but we believe v402 is what it should have been: more secure, more flexible, agent-native, and designed for real settlement workflows with receipts, relayers, and execution guarantees.

What is $UAID?

$UAID is a stablecoin built specifically for AI agents. It’s designed for programmable settlement, agent-to-agent payments, and verifiable transaction flows — not just “a stablecoin on Solana.

Is Valeo non-custodial?

Yes. Valeo is built with non-custodial wallet control. Users hold their own keys, and the app is designed around security-first execution and private transfers.

What features are already in the app?

The iOS beta includes: Solana wallet (send / receive) Swaps AI agent execution (swap, send, actions) Private send feature Continuous UX improvements And the card program is in active development.

Where can I buy $VALEO?

$VALEO is live on Solana and launched through Pump.fun. Mint Address: nn944oFMxsHg9AnEuBHWxtBpGjRX3DRxx86PseuDrPJ Always verify the mint address before buying.

What is x402 Sentinel?

Sentinel is the audit and compliance layer for x402-powered agent payments. It records payment intent, verifies execution, and produces structured, verifiable transaction trails for autonomous systems.

Does Sentinel control or hold funds?

No. Sentinel is non-custodial. It does not hold or manage user funds. It operates as a verification and compliance layer on top of x402 transactions.

Who is Sentinel built for?

Sentinel is designed for teams deploying AI agents in production, including platforms, enterprises, and infrastructure providers that require structured audit trails and verifiable financial accountability.

How does Sentinel ensure payments are verifiable?

Sentinel generates replay-safe receipts and binds payment intent to execution outcomes. Each transaction can be independently validated on-chain, ensuring that the recorded intent matches the actual settlement.
