Settlement Risk
Definition & Nature of the Risk
Settlement risk refers to the possibility that an asset transaction, once initiated, fails to complete as intended. In traditional finance, this includes the risk that one party delivers cash or securities while the counterparty fails to do so. In the context of tokenized index funds like OLTA, the concept takes on new dimensions:
On-chain asset conversions may fail due to insufficient liquidity, oracle desynchronization, or network congestion.
NAV mismatches may occur if fund token issuance/redemption is not aligned with current asset valuations.
Volatility between trade confirmation and settlement can lead to slippage or unfair execution.
In legacy systems, most ETFs settle via batch processes and are subject to T+1 or T+2 timelines. Meanwhile, OLTA operates in a 24/7 environment where real-time execution meets continuous NAV tracking raising unique challenges in precision, fairness, and liquidity assurance.
Key OLTA Specific Settlement Risks
NAV Desynchronization
If NAV calculations are delayed or based on outdated price feeds, entry/exit transactions may occur at stale prices.
Slippage & Market Impact
On-chain trades executed during periods of low liquidity or high volatility may cause execution prices to diverge from target NAV.
Liquidity Gaps in Constituents
Indexes with long-tail or low-liquidity tokens may face difficulties executing redemptions or portfolio adjustments efficiently.
Oracle Dependency
Reliance on price feeds (e.g., Binance API, Coinbase API) introduces risk if those sources become unavailable or manipulated.
Execution Risk Considerations
While TWAP and VWAP provide robust methodologies for index valuation, their direct use in execution flows must be carefully assessed:
Latency risk: spreading transactions over time can expose orders to changing market conditions.
Extreme events: in black swan scenarios, staggered execution may capture unfavorable price swings, magnifying losses.
Slippage vs. NAV gap: prolonged execution may diverge from the NAV reference, creating settlement mismatches.
Mitigation Strategies by OLTA
Real-Time NAV Synchronization
NAV calculations are continuously updated using volume-weighted average prices (VWAP), smoothed with time-weighted algorithms (TWAP).
Redemptions and issuances are only allowed when NAV is confirmed by dual-oracle validation.
Dynamic Liquidity Buffering
OLTA may allocate a small portion of fund weight (e.g., 2–5%) in stablecoins (e.g., USDC) to facilitate instant exits or rebalancing without causing internal disruption.
This approach is not common in traditional index design but is justified by OLTA’s real-time, on-chain execution architecture.
Slippage-Aware Execution Engine
Trade execution logic includes price impact thresholds, rejecting orders that would trigger excess deviation from NAV.
Orders may be split into smaller tranches to avoid moving markets.
Fallback Mechanisms for Oracle Failure
In case of primary oracle failure, OLTA switches to secondary sources and delays settlement until confirmation is re-established.
Settlement Circuit Breakers
Under high volatility, OLTA can pause redemptions or subscriptions temporarily to protect fund integrity.
Execution approach proposal:
Use Brut Price (spot) for actual execution flows when speed and certainty are critical (e.g., deposits, redemptions).
Reserve TWAP/VWAP smoothing primarily for valuation and index construction, ensuring transparent NAV without introducing unnecessary execution risk.
Execution approach will be disclosed in each Index factsheet and prospectus. (See more details at TWAP/VWAP Smoothing)
Why This Matters
Traditional ETFs can rely on delayed settlement and human oversight to reconcile mismatches. OLTA, operating as a permissionless, smart-contract-based platform, must embed resilience and fairness into the logic itself. Without proper safeguards, the risks of value leakage, unfair arbitrage, or loss of trust become real.
Settlement risk, if unmanaged, undermines the credibility of index products. With OLTA, automated infrastructure is carefully designed to neutralize this risk while preserving the advantages of real-time execution, transparency, and low-cost access.
