Settlement that proves itself — to anyone

Value moves atomically or not at all: delivery-versus-payment in one indivisible transaction, oracle attestations bringing off-chain truth on-chain with replay protection, and every settled transfer signed into an append-only record that outlives us. Trust is exported, not requested.

How it works

The mechanics a diligence team will ask about

Atomic by construction

Either both legs settle or neither does — no fails to chase.

Atomic DvP — asset and payment settle in one indivisible transaction across supported environments
Payment-for-obligation — construction draws, waivers, and receipts swap atomically with their payment
Instant XRPL clearing — on-ledger finality in seconds where programs run on XRPL

Truth with provenance

Off-chain facts arrive signed, verified, and replay-protected.

EIP-712 attestations — typed, signed statements — NAV, meter readings, inspections — verified on-chain
m-of-n aggregation — multi-oracle medians with signer allowlists and staleness windows
Chainlink integration — market data and Proof of Reserve feeds where programs need them

Capabilities

What ships in the box

Atomic DvP

Delivery-versus-payment as one transaction — the settlement pattern your counterparty's risk team actually wants to see.

Oracle attestation framework

EIP-712 signing, nonce/replay protection, signer allowlists, staleness windows — off-chain truth with provenance.

Append-only audit trail

Every decision and settlement cryptographically signed into a record that's exportable and independently verifiable.

Instant XRPL clearing

Hooks-enforced logic with on-ledger finality in seconds for lending and payment programs.

Deterministic execution

Integer math, no wall-clock dependence, no unseeded randomness — the same inputs always produce the same state.

Reconciliation exports

Settlement records formatted for your admin, auditor, and lender reporting — no manual re-keying.

Specifications

The details a diligence team asks for

Settlement environments	EVM (ERC-3643 programs), XRPL (Hooks, MPTs), Unykorn L1 (WASM)
Atomicity	DvP and payment-for-obligation swaps settle in single indivisible transactions
Oracles	EIP-712 attestation framework; m-of-n aggregation; Chainlink feeds where required
Audit trail	Append-only, signed per event; verifiable without access to Unykorn systems
Determinism	Integer minor units; no floats, no wall-clock, no unseeded randomness in settlement
Finality	Sub-second on the L1; seconds on XRPL; chain-native on EVM
Fee posture	Platform fees only; zero transaction-contingent fees
