REFERENCE FLOW · FOR THE STELLAR ECOSYSTEM

RAP × Stellar x402: pre-settlement compliance decision

Stellar connects stablecoins, cross-border anchors and x402 agentic payments. OceanAlt adds the missing link: a machine-executable compliance decision before value moves — should this pay, and why — then settle on Stellar's compliant rails.

Status: The decision layer is live now — the call below hits a real production endpoint. Stellar settlement is the target rail; we're seeking ecosystem collaboration with the Stellar Development Foundation to wire the last-mile settlement. This is a reference flow, not a shipped Stellar integration.

One decision gates one Stellar x402 settlement: settle only on allow; decline/review both carry verifiable evidence.

Runnable now: the decision call (real production endpoint)

Pass the payee address you're about to pay; get allow/review/decline + verifiable evidence. Free, no key. USDC payee addresses on Stellar screen the same way (sanctions/list checks are chain-agnostic).

curl -s "https://oceanalt.com/api/decide?to=0x8589427373D6D84E98730D7795D8f6f8731FDA16"

That address is Tornado Cash (OFAC-sanctioned) — returns decline + evidence. A normal address returns allow.

Why this fits Stellar

· Stellar already links USDC, cross-border anchors (SEP-31), x402 and real off-ramp — exactly the settlement rail a decision should land on once it passes.
· OceanAlt stays vendor-neutral: the decision layer composes multiple intelligence sources and doesn't compete with L1 features — it adds compliance decision + settlement admission above the network.
· RAP is an open pre-settlement compliance profile (PASS/FAIL/UNCERTAIN + evidence + retry) — a companion reference profile for Stellar x402.
