Step 1 · Trade Capture (Post-Trade Handoff)Policy-EnforcedBlockchain-Native
The executed RWA trade arriving from the Securities rail — now the cross-chain settlement problem begins.
**Cross-rail reference: Stages 1-4 fired on the Securities Trading rail.** An RWA trade has been executed — e.g., Ondo OUSG on Ethereum against USDC payment on Base. The security token and payment token are on different chains. This path solves the cross-chain DvP problem. L5 lit only — handoff is recordkeeping. All earlier compliance gates (identity, sanctions, discovery) were satisfied on the originating rail.
Step 2 · CRE Settlement Intent RegistrationCode-EnforcedBlockchain-Native
A CLS settlement window for FX — both legs are registered, locked, and will execute simultaneously or not at all.
Chainlink CRE registers the settlement intent on both chains. The security token (Ethereum) and payment token (Base) are locked in escrow contracts. CRE's cross-chain runtime monitors both chains simultaneously, ensuring neither leg can be released without the other. L2+L3 lit: consensus and execution on both chains coordinate through Chainlink's DON (Decentralized Oracle Network). This is the compliance center of gravity — cross-chain atomic coordination. D7 (Travel Rule) applies to cross-chain movement metadata; D10 (Operational Resilience) applies to the oracle network's liveness.
Step 3 · Bilateral Compliance VerificationCode-EnforcedBlockchain-Native
The bilateral compliance check before a cross-border securities settlement — both parties verify the other meets their regulatory requirements.
Both counterparties run compliance verification: sanctions screening, whitelist checks (for security tokens with transfer restrictions), and jurisdiction-specific requirements. In the Kinexys pilot, JPMorgan's compliance layer screens against its own regulatory framework while the counterparty's compliance runs independently. L3 Execution lit — bilateral compliance is code-enforced. Each side must pass independently; CRE releases the atomic settlement only when both sides confirm. D1 (Identity) covers KYC/beneficial ownership; D2 (Sanctions) covers OFAC/EU screening; D8 (Licensing) covers issuer and venue authorization.
Step 4 · Atomic Cross-Chain SettlementCode-EnforcedBlockchain-Native
The CLS settlement — both currency legs release simultaneously. But here, it's securities on one chain and payment on another, coordinated by an oracle network.
CRE releases both legs atomically: the security token transfers on Ethereum while the USDC payment transfers on Base. Chainlink's DON ensures atomicity across chains — if either leg fails, both revert. L1+L2+L3 lit on both chains. This is cross-chain DvP: the same guarantee as same-chain atomic settlement, but across heterogeneous blockchains. D9 (Prudential) applies — the oracle network is now a systemically important piece of market infrastructure. Settlement finality is determined by whichever chain confirms last (typically Base's 2s block time vs. Ethereum's ~12s).
Step 5 · Position Update & ReconciliationPolicy-EnforcedBlockchain-Native
Both custodians updating their books — the buyer has the security on Ethereum, the seller has USDC on Base.
Both counterparties update their positions across chains. The buyer's custody account on Ethereum shows the security token; the seller's account on Base shows the USDC payment. L4+L5 lit: position updates are policy-enforced at the application layer. Reconciliation is trivial — the atomic settlement is the authoritative record on both chains. Cross-chain position aggregation is the new compliance burden: custodians must track net exposure across heterogeneous chains and report to regulators accordingly.
Step 6 · Settlement Finality & ReportingPolicy-EnforcedBlockchain-Native
The settlement confirmation with cross-chain transaction hashes — a new kind of audit trail that spans multiple blockchains.
Settlement is final on both chains. The audit trail includes transaction hashes on Ethereum (security leg) and Base (payment leg), linked by Chainlink CRE's settlement record. Regulatory reporting captures the cross-chain settlement as a single economic event. L5 Application lit only. **Open question:** when securities settle across chains, which chain's regulatory framework governs the settlement — the security's chain, the payment's chain, or both? JPMorgan's Kinexys pilot suggests a coordinated bilateral reporting model where both chains' regulators receive the full transaction record.
