2. Index Objective

The standard against which digital asset strategies are measured.

The Cryptex Digital Market Cap Index exists to do what no index in digital assets has done properly: capture a broad representation of the digital asset market cap in a single, transparent, rules-based measure.

The index provides broad, diversified representation across five thematic sectors of the digital asset ecosystem — balancing the dominance of major networks with meaningful exposure to infrastructure, applications, community-driven assets, and emerging projects.

The Cryptex Digital Market Cap Index is designed to serve as:

  • A definitive benchmark. The standard against which active digital asset strategies are measured. Every portfolio manager, every fund, every protocol — measured against one number.
  • A composable on-chain primitive. Natively integrated into DeFi as collateral, a base trading pair, or a building block for structured products. The index doesn't just track the market — it participates in it.
  • A passive exposure framework. For allocators seeking diversified digital asset exposure without the operational complexity of managing individual positions across multiple chains, venues, and custody solutions.

3. Constituent Eligibility

Inclusion and exclusion criteria.

Inclusion in the Cryptex Digital Market Cap Index is governed by strict, rules-based criteria. No exceptions. No discretionary overrides. An asset qualifies or it doesn't.

3.1 Eligibility Criteria

  • 3.1.1 Minimum Market Capitalization. Trailing 90-day volume-weighted average market capitalization of at least $200 million, calculated using free-float circulating supply.
  • 3.1.2 Minimum Liquidity. Trailing 30-day average daily trading volume of at least $10 million across eligible venues. Volume is measured across both centralized and decentralized exchanges meeting the index's venue quality standards.
  • 3.1.3 Exchange Availability. Listed and actively traded on a minimum of three exchanges meeting the index's venue quality standards. At least one listing must be on a venue with a Chainlink price feed available.
  • 3.1.4 Chainlink Feed Requirement. An active Chainlink price feed is a hard requirement. No Chainlink coverage, no inclusion — regardless of market capitalization or liquidity. The index's pricing integrity and Proof of Reserves infrastructure depends on Chainlink data feeds. This is non-negotiable.
  • 3.1.5 Blockchain and Token Standard. The asset must be a native token or conform to a widely adopted standard (ERC-20, SPL, etc.) on a public, permissionless blockchain. Smart contracts (if applicable) must have been deployed for a minimum of 6 months.

3.2 Exclusion Criteria

The following categories are excluded regardless of market capitalization or liquidity:

  • Stablecoins. Assets pegged to fiat currencies, commodities, or other external reference values (e.g., USDT, USDC, DAI). These are settlement instruments, not investable digital assets.
  • Wrapped tokens. Tokenized representations of assets already eligible in their native form (e.g., WBTC, WETH, stETH). No double-counting.
  • Rebasing tokens. Assets with elastic supply mechanisms that automatically adjust holder balances.
  • Centralized exchange tokens. Native tokens of centralized exchanges (e.g., BNB, FTT, CRO). Concentration of supply control and regulatory exposure disqualify these assets.
  • Assets under active enforcement. Assets subject to active regulatory enforcement actions by the SEC, CFTC, DOJ, or equivalent authorities in the EU, UK, or other major jurisdictions. Subject to expedited review by the methodology committee.

3.3 Methodology Committee Discretion

The methodology committee retains limited discretion in three areas only: sector assignment, edge cases near eligibility thresholds, and extraordinary circumstances such as smart contract exploits or sudden regulatory actions. The committee has zero discretion over the weighting methodology, rebalancing schedule, or concentration cap. These parameters are governed by the rules in this document and may only be modified through CTX governance.

4. Sector Classification

Five-tier sector model.

The digital asset ecosystem is not a monolith. It has structure. The Cryptex Digital Market Cap Index reflects that structure through five thematic sectors:

4.1 Five-Tier Sector Model

  1. Major Layer Networks. The dominant base-layer protocols — the primary settlement and value-transfer infrastructure of the entire ecosystem. Inclusion requires both dominant market capitalization and a functioning mainnet with significant economic activity. This is the foundation.
  2. L1 + L2 Infrastructure. Layer 1 blockchains and Layer 2 scaling solutions providing execution, interoperability, oracle, and middleware infrastructure. These assets power the operational layer beyond the major networks.
  3. Memes & Community Assets. Assets whose value derives from community adoption, cultural significance, and network effects rather than technical utility. Community-driven value creation is a structurally significant category within digital assets — representing substantial market capitalization and trading volume. Ignoring it would be intellectually dishonest. This index doesn't ignore it.
  4. DeFi Applications. Tokens governing or representing economic interest in decentralized finance protocols — lending, trading, insurance, asset management, naming services, and storage infrastructure. This is the application layer.
  5. Innovation & Emerging. Early-stage projects, novel categories, and assets that don't fit cleanly into the other four sectors. This tier provides frontier exposure and serves as an incubation layer for assets that may migrate upward as they mature.

4.2 Sector Assignment Process

Sector assignments are determined by the methodology committee based on each asset's primary function, market positioning, and ecosystem role. Assignments are reviewed quarterly during the standard rebalancing process. An asset may be reassigned if its primary function has materially changed since the last review.

All sector assignment decisions and rationale are published alongside each quarterly rebalancing report. Full transparency. No black boxes.

5. Weighting Methodology

Sector-stratified. Equal-weighted-within-tier.

5.1 Overview

The Cryptex Digital Market Cap Index employs a sector-stratified, equal-weighted-within-tier methodology designed to balance three competing objectives: market representation, diversification, and simplicity. If you can't explain it clearly, you shouldn't be running an index.

5.2 Sector Allocation

Each sector receives an aggregate allocation based on its share of total index weight. Sector allocations are recalculated quarterly using the aggregate market capitalization of each sector's eligible constituents relative to the total eligible universe:

W(Sk, t) = Σ MCap(ai, t) for ai ∈ Sk  /  Σj=1..5 Σ MCap(ai, t) for ai ∈ Sj

5.3 Intra-Sector Weighting

Within each sector, constituent assets are equally weighted:

w(ai) = W(Sk) / nk    ∀ ai ∈ Sk

Two exceptions apply:

Tier 1 (Major Layer Networks): The market capitalization disparity among Tier 1 assets is extreme — Bitcoin's market cap exceeds the combined cap of all other Tier 1 constituents by a significant multiple. Equal weighting here would be artificial. Within Tier 1, weights reflect relative market capitalization, subject to the concentration cap. This preserves Bitcoin's true market dominance while preventing single-asset overconcentration.

Tier 5 (Innovation & Emerging Assets): CTX, the governance token of the Cryptex protocol, is included in Tier 5 at a fixed weight of 2.0%. CTX does not meet the standard eligibility criteria applied to other constituents. This self-inclusion is a deliberate design decision, disclosed transparently. All other Tier 5 constituents are equally weighted from the remaining tier allocation.

5.4 Concentration Cap

No single constituent may exceed 40% of total index weight.

w(ai, t) ≤ 0.40    ∀ ai ∈ U

At initial calculation, this cap is binding only for Bitcoin, whose unconstrained market-cap weight within Tier 1 would exceed 55%. Excess weight above the cap is redistributed among remaining Tier 1 constituents on a pro-rata basis.

Disclosure: CTX (Rank 34), the governance token of the Cryptex protocol, is included in the Innovation and Emerging Assets sector at a 2.0% weight. CTX does not meet the standard eligibility criteria applied to other index constituents. Its inclusion is a deliberate design decision by the protocol creators, disclosed transparently and subject to ongoing review by CTX governance participants.

6. Index Calculation

Real-time. Continuous. Verifiable.

6.1 Real-Time Index Value

The index value is calculated continuously using Chainlink price feeds for each constituent. Between rebalancing events, the index value at time t is computed as:

V(t) = V(tr) · Σi=1..N w(ai, tr) · π(ai, t) / π(ai, tr)

Where V(tr) is the index value at the most recent rebalance, w(ai, tr) is the weight of constituent ai at that rebalance, π(ai, t) is the current Chainlink price feed, and π(ai, tr) is the price at the rebalance date. N is the number of active constituents (40 under normal conditions; fewer if a constituent is temporarily excluded due to oracle circuit breaker activation).

This return-based formulation ensures the index tracks weighted performance regardless of nominal price levels. Equivalently:

V(t) = Σi=1..N qi · π(ai, t) / D

Where qi is the number of units of asset ai held per unit of the index (determined at each rebalance), and D is the index divisor.

6.2 Index Divisor

The divisor D is adjusted at each rebalancing event to ensure index value continuity. At rebalance time tr:

qinew = wnew(ai) · V(tr) / π(ai, tr)

The divisor is recalculated:

Dnew = Σi=1..N qinew · π(ai, tr) / V(tr)

This ensures the index value immediately before and after rebalancing is identical. No gap. No discontinuity.

6.3 Index Calculation Agent

The index calculation agent is responsible for continuous computation of the real-time index value and execution of divisor adjustments at each rebalancing event. The calculation agent operates independently from Cryptex Finance to ensure objectivity and accuracy.

Index Calculation Agent: TBD

6.4 Base Value

The Cryptex Digital Market Cap Index base value is TBD, set as of the base date of February 20, 2026.

7. Oracle Infrastructure

Chainlink. Dual verification.

7.1 Chainlink Price Feeds

All constituent prices are sourced from Chainlink's decentralized oracle network. Chainlink aggregates spot prices from multiple centralized and decentralized exchanges through independent node operators, delivering manipulation-resistant pricing that no single-exchange feed can match.

π(ai, t) = ChainlinkFeed(ai, t)

7.2 Chainlink Proof of Reserves

The Cryptex Digital Market Cap Index is designed to support 1:1 asset-backed implementations. Chainlink Proof of Reserves provides independent, automated, continuous verification that assets held in custody match the total supply of outstanding tokens in any index-linked product.

Price feeds confirm what the index is worth. Proof of Reserves confirms the underlying assets actually exist in any product tracking the index. Trust, but verify. Then verify again. On-chain.

7.3 Staleness and Deviation Thresholds

Staleness threshold. If a Chainlink price feed has not updated within its expected heartbeat interval, the constituent is temporarily excluded. Its weight is redistributed pro rata among remaining constituents until the feed resumes.
Deviation threshold. If a constituent's price feed reports movement exceeding 15% within a 5-minute window, the oracle circuit breaker activates. Operations involving that constituent's weight contribution are paused until prices stabilize.
Proof of Reserves discrepancy. If the attestation detects a discrepancy between custodied assets and outstanding token supply in any index-linked product, protective measures activate per that product's operating procedures.

8. Rebalancing

Quarterly rebalance. Six-step process.

8.1 Scheduled Rebalancing

The index rebalances quarterly on the first business day of each calendar quarter (January, April, July, October). Each event follows six steps:

  1. Eligibility screening. All digital assets meeting the criteria in Section 3 are identified. Current constituents that no longer qualify are flagged for removal.
  2. Constituent selection. From the eligible universe, 40 assets are selected across five sectors. The methodology committee assigns sector classifications. Within each sector, assets are ranked by market capitalization.
  3. Sector allocation recalculation. Sector allocations are recalculated based on aggregate market capitalizations per the formula in Section 5.2.
  4. Weight assignment. Weights are assigned per Section 5.3, subject to the concentration cap in Section 5.4.
  5. Divisor adjustment. The index divisor is adjusted per Section 6.2 to maintain value continuity.
  6. Transition period. Weight changes are implemented over a five business day transition window. Weights adjust linearly from old to new, minimizing market impact and reducing predictable rebalancing order flow.

8.2 Rebalance Rate Cap

No constituent's weight may change by more than 2 percentage points per rebalancing cycle. If the required change exceeds this cap, the adjustment is spread across multiple cycles. No exploitable patterns. No front-running opportunities.

8.3 Extraordinary Rebalancing

An off-cycle rebalance may be triggered when:

  • A constituent suffers a smart contract exploit resulting in material loss of value.
  • A constituent is delisted from all qualifying exchanges.
  • A constituent's market capitalization falls below $100 million (50% of the eligibility threshold) for 10+ consecutive days.
  • A Chainlink price feed for a constituent is permanently discontinued.

Extraordinary rebalances follow the same methodology on an accelerated 48-hour timeline. All extraordinary rebalances must be ratified by CTX governance through the emergency proposal procedure.

9. Constituent Changes

Additions and removals.

9.1 Additions

New constituents may be added at a scheduled quarterly rebalance if: all eligibility criteria in Section 3 are met, the asset has met the minimum market capitalization threshold for at least 90 consecutive days, a Chainlink price feed is available and operational for at least 30 days, and the methodology committee has assigned a sector classification.

9.2 Removals

Constituents are removed at a scheduled quarterly rebalance if: the asset no longer meets market capitalization or liquidity thresholds (having fallen below for 30+ of the preceding 90 days), the asset's Chainlink price feed has been discontinued, or the asset triggers any exclusion criterion in Section 3.2. Also via extraordinary rebalancing per Section 8.3.

9.3 Transition

When a constituent is added or removed, the transition is implemented over the standard five business day window. The index divisor is adjusted to ensure value continuity.

10. Governance

What can change. What cannot.

10.1 Governable Parameters

The following may be modified through CTX governance:

  • Protocol fee levels (within predefined bounds)
  • Oracle venue quality standards
  • Eligibility threshold levels (market cap and volume minimums)
  • Emergency pause activation
  • Protocol upgrade proposals (subject to extended timelock)

10.2 Non-Governable Parameters

The following are fixed. Period.

  • Equal-weight-within-tier methodology (Tiers 2–5)
  • Relative market-cap weighting within Tier 1
  • 40% constituent concentration cap
  • Five-sector classification structure
  • Quarterly rebalancing schedule
  • Chainlink oracle requirement
  • 1:1 asset-backing design requirement

10.3 Governance Process

ParameterSpecification
Quorum400,000 CTX
Standard Proposal7-day voting period, 48-hour timelock
Emergency Proposal48-hour voting period, 12-hour timelock
Emergency Expiry72 hours unless ratified by standard proposal

11. Risk Factors

Known risks. Disclosed transparently.

  • 11.1 Market Risk. Digital asset prices are highly volatile. The index may experience significant drawdowns during market-wide selloffs. Correlation among crypto assets increases substantially during stress periods, reducing the diversification benefit of the multi-asset structure.
  • 11.2 Concentration Risk. Bitcoin represents 40% of the index at the concentration cap. Adverse BTC price movements will disproportionately impact index performance.
  • 11.3 Liquidity Risk. Certain constituents, particularly in Tiers 3–5, may have lower liquidity profiles. This may impact rebalancing costs and create wider spreads during market stress.
  • 11.4 Smart Contract Risk. The protocol’s smart contracts have undergone four independent security audits (Quantstamp 2021, Cantina September 2024, Pashov October 2024). Smart contract risk cannot be fully eliminated.
  • 11.5 Oracle Risk. The index depends on Chainlink oracle infrastructure for both pricing and reserve verification. Feed unavailability, manipulation, or failure would impact index operations.
  • 11.6 Methodology Committee Risk. Sector assignment and edge-case eligibility decisions involve human judgment. The committee’s discretion, while limited, introduces a non-algorithmic element.
  • 11.7 Self-Inclusion Risk. CTX is included as a constituent outside standard eligibility criteria. This creates a potential conflict of interest between the index provider and the index itself.
