The execution layer for zero-cost FX and internally settled money.
derien resolves all currency relationships simultaneously with deterministic finality.
Atomically. Deterministically. Zero residual.
What was previously theoretical is now executable.
What this enables
Zero spread FX
Conversion without a cost layer. Spread becomes a structural artefact of the old model — not a property of exchange itself.
Internally settled networks
Settlement that lives inside the network. No external rails, no counterparty exposure, no settlement lag.
Social liquidity
Liquidity that emerges from network relationships — not warehoused by intermediaries or priced through fragmented venues.
Network-native money
Currency as a property of the network, not a foreign object passed through it. Money that moves at the speed of information.
Trading becomes settlement
The distinction between executing a trade and settling it collapses. One atomic step. No residual. No lag between intention and finality.
The architectural difference
FX today resolves sequentially. derien resolves the system.
Old — pair-by-pair matching
New — simultaneous system resolution
This is not theoretical. The system runs.
The proof
25
Years of live system evolution
Developed and tested under real market conditions since 2000. The failure modes at global dimensionality cannot be inferred from design — they are discovered under sustained load. We have resolved them.
130
Decimal precision — required for exact multi-currency resolution
Fractional multi-currency resolution at scale requires numerical precision floating-point arithmetic cannot provide. Rounding error becomes residual imbalance. Ours does not.
0
Residual imbalance
Five currency pairs. One atomic settlement. No residual. Not modelled. Executed. The system resolves all currency relationships simultaneously or not at all.

Residual across all currencies: 0 — System state is fully consistent at execution.
The constraint
External settlement makes friction inevitable.
Modern FX infrastructure is built on matching. Orders are paired instrument by instrument.
Relationships between currency pairs are not resolved directly — they are approximated,
enforced through arbitrage, corrected over time.
This works when settlement is external and time allows inconsistencies to exist.
When settlement becomes internal and atomic, this model breaks.
In an internally settled system, inconsistency cannot exist even momentarily.
The requirement
All currency relationships must resolve simultaneously.
Not sequentially. Not through arbitrage. Not after the fact.
Every currency relationship must hold at the moment of execution —
producing a deterministic, consistent final state in one step.
This is a different class of problem than matching. It is high-dimensional
state resolution under continuous fractional flow. Conventional FX infrastructure
cannot do it. No amount of better routing, tighter spreads, or faster rails changes this.
Without this, a network cannot operate as an internally consistent financial system.
For institutional participants
Eliminates cross-pair inconsistency at execution
All currency relationships are resolved simultaneously. Inconsistency cannot exist at the moment of execution — not temporarily, not structurally.
Removes dependence on arbitrage for price alignment
Consistency is achieved as part of execution itself — not restored afterward by external actors. The system does not rely on arbitrage to correct imbalance.
Enables atomic multi-asset settlement
Multi-currency demand is resolved in one step. No sequential processing, no residual imbalance, no dependency on future correction.
Reduces capital fragmentation across trading books
Internal settlement removes the need to prefund external positions. Capital ceases to fragment across venues and instead concentrates where pricing is consistently best.
VoIP didn't reduce cost.
It removed it as a variable
by changing the underlying layer.
FX follows the same path. When settlement becomes internal,
conversion ceases to be priced. It becomes a property of the network itself.
Independent validation — Futures & Options World, December 2000
"Makes an evolutionary leap — bypassing perhaps years of system development to deliver technology that outperforms the competition by a colossal margin."

Whoever controls this layer controls network-native money.
The question is who that is — and who is forced to depend on them.
The system is built. Remaining gating factors are regulatory activation and commercial deployment — not feasibility. We are now engaging with institutional partners.
