Executive Summary: From “Moving Assets On-Chain” to “Asset Restructuring”

Looking back at the history of DeFi, every major liquidity breakthrough has come from successfully abstracting and standardizing asset properties. ERC-20 abstracted value transfer, creating a universal standard for tokens and payments. AMMs abstracted the human role of market makers, enabling trading to be executed entirely by code.

Yet in the RWA (Real-World Asset) sector, the industry remains stuck in the RWA 1.0 phase of mere "asset migration". Projects such as Ondo Finance and tokenized Treasury products still follow a model of "static mirroring": real-world bonds are wrapped through SPVs and legal trusts, then represented 1:1 as ERC-20 tokens on-chain. This model does solve the problem of putting assets on-chain — but it preserves all the rigidity of traditional finance. Risk and return remain bundled inside an indivisible black box. Users are left to passively accept an asset’s average risk profile, with no ability to customize or actively manage it.

This paper argues that the core of RWA 2.0 lies in bringing structured finance on-chain as a native primitive. In this framework, AquaFlux is not merely an RWA protocol — it is a general-purpose language for financial engineering.

Just as Solidity serves as the programming language for smart contracts, AquaFlux serves as a programming language for asset risk. Through a standardized syntax—P (Principal), C (Coupon), and S (Shield)—it “translates” real-world assets into on-chain financial primitives that are legible, programmable, and composable. Within this system, the Tri-Token model is only the surface form. Its true core is structured tranching and the risk waterfall: a grammar that allows DeFi protocols to decompose and recombine trillions of dollars of traditional assets with the same flexibility as LEGO blocks.

Chapter I: The Inevitability of Structuring (Breaking the "One-Size-Fits-All" Paradigm)

1.1 The Limits of Static RWAs: The Black Box of Risk

The prevailing model of static RWAs is constrained by an “impossible triangle”: high compliance costs, fragmented liquidity, and the absence of native risk pricing.

•             The Illusion of Fungibility: The ERC-20 standard assumes that all tokens are fungible. For RWAs, this assumption is fatally misleading. Every corporate bond, every property, carries a distinct risk profile. Wrapping these heterogeneous assets into homogeneous tokens does not eliminate their differences — it merely obscures them. The heterogeneity of underlying risk is hidden beneath a uniform interface.

•             Passive Exposure: In a static model, when a real-world asset defaults, on-chain token holders are left with no recourse beyond waiting for off-chain legal processes to unfold. There is no native, on-chain mechanism to absorb or reallocate risk. Holders can only endure losses passively, bound to a legal and temporal framework that lies entirely outside the chain.

This is the structural ceiling of RWA 1.0: assets may move on-chain, but risk remains opaque, indivisible, and fundamentally unprogrammable.

1.2 Defining AquaFlux: Structured Finance Legos

At its essence, AquaFlux internalizes the construction logic of mature instruments in traditional finance — such as CLOs (Collateralized Loan Obligations) and ABS (Asset-Backed Securities) — into a standardized system of smart contracts.

The AquaFlux protocol can be understood as a set of Structured Finance Legos. Instead of moving raw RWAs on-chain as monolithic asset packages, AquaFlux decomposes them into three standardized, tradable, and composable building blocks under the Tri-Token architecture: P, C, and S. These modules allow markets and protocols to assemble risk–return profiles on demand, rather than inheriting a single, fixed outcome.

•             Input Layer: Any yield-bearing asset that generates cashflow—Treasuries, corporate bonds, commercial paper, and similar instruments.

•             Processing Layer (Flux Engine): A smart contract–driven structuring engine that decomposes assets according to the rules of tranching and the risk waterfall.

•             Output Layer: Three standardized modules with distinct risk–return characteristics: P (Principal), C (Coupon), and S (Shield).

This marks a transition in RWAs from asset containers to financial organisms. Through structuring, AquaFlux shifts the definition of an asset’s risk–return contract away from a single issuer’s preset terms and into a dynamic, on-chain process governed by market interaction. Assets are no longer static products to be held—they become living structures that can be continuously decomposed and recomposed by the chain itself.

Chapter II: Core Grammar: The Risk Waterfall and Tranching Logic

The core of the AquaFlux language lies in two operations: decomposition and recomposition. To understand this language, one must first grasp its foundational grammar — the risk waterfall.

2.1 The Waterfall: The Power to Define

In financial engineering, the order of payment—seniority—determines the nature of an asset. The AquaFlux protocol encodes this hierarchy directly on-chain, defining the priority of cashflows in code and, in doing so, creating distinct financial properties.

   Asset Cashflow → Senior (P) → Mezzanine (C)→ Equity / Junior (S)

1.           P-Token (Principal) — Senior Tranche

￮              Definition: An on-chain zero-coupon bond—an asset that does not generate interim interest and is redeemed at face value at maturity.

￮              Grammar Logic: P-Token enjoys the highest payment priority. As long as default losses on the underlying asset do not exceed the thickness of the S-Token layer, P remains fully protected. This structural design strips away idiosyncratic credit risk, allowing P-Token to function as near-perfect collateral in DeFi lending markets with high LTV ratios.

2.           C-Token (Coupon) — Mezzanine Tranche

￮              Definition: A pure carrier of cashflow.

￮              Grammar Logic: By separating yield from principal, C-Token removes the capital cost of holding the underlying asset, creating an instrument of exceptional capital efficiency. Its value is highly sensitive to interest rate movements, making it ideal for participants who seek not only yield, but also exposure to — and expression of — rate expectations.

3.           S-Token (Shield) — Junior / Equity Tranche

￮              Definition: A risk absorber and the capture layer for excess returns.

￮              Grammar Logic: S-Token is the most complex “word” in the AquaFlux language. It sits at the bottom of the waterfall as first-loss capital, absorbing shocks before any other layer is affected.

2.2 S-Token: A Dynamic Container for Risk Pricing

S-Token represents AquaFlux’s most fundamental innovation and its point of departure from existing protocols. It assumes uncertainty while earning commensurate rewards, introducing a dual construct: Shield and Surplus.

•             The Shield Mechanism: When an underlying asset defaults or suffers impairment, the capital staked in the S-Token pool is the first to be burned or slashed, absorbing losses before they reach P-Token or C-Token holders. S-Token thus functions as the system’s on-chain airbag—a native buffer that transforms credit risk into a programmable layer of protection.

•             The Surplus Mechanism: Risk and return are inseparable. As compensation for bearing the possibility of total loss, S-Token captures the system’s richest sources of excess return (alpha):

a.            Coupon Share: The risk premium carved out of the underlying asset’s yield.

b.            Protocol Fees: Revenue generated by the protocol itself.

c.             Incentives: Governance token emissions and system-level rewards.

Together, these mechanisms create a dynamic equilibrium. When the market perceives rising risk in an asset, the price of S-Token declines, as higher yield is required to compensate for uncertainty. This elevated APY, in turn, attracts risk-seeking capital to mint and hold S-Token, automatically thickening the protective layer beneath P and C.

This feedback loop embodies AquaFlux’s self-regulating grammar: risk is not merely borne — it is continuously priced, attracted, and reabsorbed by the market itself.

Chapter III: Financial Legos: From Assets to Composable Sentences

Once assets are standardized by the AquaFlux language into P, C, and S, investors are no longer passive holders—they become active builders. On-chain, composition matters more than possession. What one holds are modules; what one expresses are strategies.

This is the power of a language: with a finite vocabulary, it can articulate infinite intent. Through different combinations of the same primitives, radically different financial expressions emerge. Crucially, these compositions are not only for traders. They are equally native to protocols themselves. Lending markets, AMMs, and yield aggregators can all treat P, C, and S as callable financial primitives, embedding structured RWAs directly into the composable fabric of DeFi.

3.1 Three Modules, Three Forms of Intent

•             P (Principal Module): P has a singular cashflow objective — recovering principal at maturity. With the highest seniority in the structure, it carries the lowest effective risk. As a result, P most closely resembles the class of assets that on-chain systems are willing to accept at high LTV ratios. It is well suited for collateralization and for serving as a foundational, “bedrock” asset within DeFi.

•             C (Coupon Module): C is oriented toward yield and rate expectations. It represents pure cashflow exposure, making it ideal for income strategies and yield-curve trading. Holders are not committing capital for principal recovery; they are expressing a view on future rates.

•             S (Risk Module): S is oriented toward credit risk and risk premia. It is the layer designed for pricing uncertainty, absorbing volatility, and capturing excess returns. Where P seeks preservation and C seeks yield, S seeks alpha.

3.2 Compositional Strategies

In this language, strategies become sentences, and P/C/S are the vocabulary.
What changes is not the asset itself, but the financial meaning it expresses.

This is the true value of Financial Legos: not the invention of new assets, but the ability for a single asset to express multiple, tradable, hedgeable, and composable financial meanings.

Chapter IV: The Evolution of Splitting: Beyond Pendle’s Time-Based Model

Across the history of DeFi, asset splitting has emerged as an increasingly explicit design pattern. What we observe is a clear evolutionary path—from simple abstractions to progressively richer structures. AquaFlux does not appear in isolation. It stands on the shoulders of earlier pioneers, completing the final missing piece in the splitting paradigm.

4.1 Pendle: Splitting Time and Yield

Pendle Finance is the pioneer of asset splitting in DeFi, achieving remarkable success with yield-bearing assets—particularly liquid staking derivatives such as stETH.

•             Splitting Model: Asset = PT (Principal) + YT (Yield)

•             Core Logic: This is fundamentally a time-based equation. PT represents principal that accretes toward par over time, while YT represents the right to future yield that decays as maturity approaches.

•             Limitation: Pendle’s model rests on a safe principal assumption—the belief that the underlying asset’s principal is effectively risk-free. In the context of stETH, this assumption largely holds. In RWAs, however, it breaks down. Corporate bonds carry inherent credit risk. If the Pendle model is applied directly to such assets, a default at the underlying level would transmit losses straight to PT holders. This constraint prevents Pendle from scaling natively into non-standard, credit-bearing RWA markets.

4.2 Polymarket: Splitting Probability and Outcome

Polymarket demonstrates a different extreme of asset splitting within the domain of prediction markets.

•             Splitting Model: Collateral (1) = YES Token + NO Token

•             Core Logic: This is an equation of probability. At all times, YES + NO = 1$.

•             Insight: Polymarket proves that by splitting a binary outcome, markets can price the probability of an event with remarkable precision. This price is not dictated by experts or models — it is discovered through real capital at risk. Probability becomes an asset, and belief becomes liquidity.

4.3 AquaFlux: Splitting Credit and Structure

AquaFlux synthesizes the strengths of both paradigms and elevates them to meet the specific demands of RWAs.

•             Splitting Model: RWA = P (Principal) + C (Coupon) + S (Credit Risk)

•             A New RWA Paradigm:

•             It inherits Pendle’s P/C logic, separating principal from yield and enabling interest-rate trading.

•             It incorporates Polymarket’s binary game logic by embedding it within S-Token. At its core, S-Token is a pricing instrument for default probability.

•             The Evolutionary Leap: AquaFlux fills the largest structural gap in the RWA domain: the tradability of credit risk itself. Before AquaFlux, distrusting an RWA meant only one option—not buying it. After AquaFlux, distrust becomes an expressible position. One can short S-Token or hold only P-Token to isolate and neutralize credit exposure. This represents the terminal form of asset splitting.

Chapter V: The Liquidity Engine: Harmonizing Speculation and Preservation

The fundamental reason traditional RWA tokens suffer from poor liquidity is simple: they are boring. They merely mirror an off-chain bond on-chain, forcing every participant to accept the same fixed yield—say, 5%—and the same undifferentiated risk. It is equivalent to asking everyone, from whales to retail users, to buy the exact same wealth product. The result is predictable: no one is truly satisfied, and no one trades.

AquaFlux inverts this logic. Instead of presenting RWAs as static instruments, it decomposes a single “boring” asset into three forms of DeFi-native gameplay that on-chain users already understand. Once an asset becomes a set of highly expressive LEGO blocks — modules that can be played with, combined, and strategized around—liquidity emerges naturally.

5.1 Three Tokens, Three DeFi Archetypes

AquaFlux is not selling bonds. It is offering three distinct tools for three archetypal on-chain users — each aligned with a different intent.

1. P-Token: On-Chain “Cash Management” / Prime Collateral

•             Target Users: Whales, DAO treasuries, stablecoin holders.

•             User Mindset:“I hold a large amount of stablecoins. I want slightly better returns than Aave deposits, but I absolutely cannot lose principal. I also don’t want to monitor markets every day.”

•             DeFi-Native Use Cases:

￮              As a Safe-Haven Asset:
P-Token is protected by the S-Token layer beneath it. In the event of default, S absorbs losses first. This makes P exceptionally resilient — functionally similar to an on-chain capital-preservation product.

￮              Looping Strategies:
Because P-Token is structurally safe, lending protocols such as Aave can assign it high LTV ratios. Users can collateralize P to borrow stablecoins, acquire more P, and repeat—creating a low-risk leveraged yield strategy that compounds spread over time.

2. C-Token: A Long Position on Rates / Pure Yield Exposure

•             Target Users: Traders, hedge funds.

•             User Mindset:“I don’t want to lock up large amounts of capital to buy a bond. I just want to trade where rates are going.”

•             DeFi-Native Use Cases:

￮              Maximum Capital Efficiency: Buying C-Token is equivalent to taking a highly leveraged position on yield. Instead of spending 100 to earn 5 in interest, one can spend a fraction of that to acquire the right to those 5 units of yield.

￮              Trading the Fed: If a participant expects rates to rise, buying C-Token becomes a direct expression of that view. As rate expectations increase, the price of C can surge. In effect, C-Token functions as an on-chain interest-rate prediction market.

3. S-Token: A Leveraged “Mining Pickaxe” / Risk Capture Layer

•             Target Users: Yield farmers, degens.

•             User Mindset:“I’m fine with high risk — as long as the APY is high enough, or there are points and airdrops to farm, I’m in.”

•             DeFi-Native Use Cases:

￮              High-APY Farming: Because S-Token bears default risk, the system routes the majority of excess returns to it. This includes: A share of the underlying asset’s yield premium, protocol fee revenue, governance token incentives.

￮              Betting on Non-Default: Holding S-Token is, in essence, a wager that the underlying asset will not fail. As long as no default occurs, S-Token holders become the highest-yielding participants in the entire structure.

5.2 The Flywheel: Letting Speculators Protect Savers

AquaFlux’s most elegant design lies in its ability to harness Web3’s speculative instinct to construct systemic security. Speculation is not treated as a problem — it is transformed into infrastructure. This creates a self-reinforcing flywheel:

1.           Initiation: An issuer brings an RWA on-chain and splits it into P, C, and S.

2.           Speculative Entry (Degens Arrive): The market observes that S-Token offers high farming yields—driven by fees and token incentives. Yield farmers enter en masse, minting and holding S-Token.

3.           Shield Thickens: As the S-Token pool grows, so does the amount of capital available to absorb losses. The protective layer becomes deeper.

4.           Principal Becomes Safer: With a thick S layer beneath it, P-Token becomes increasingly resilient—structurally insulated from default risk.

5.           Whales Enter: Observing that P-Token is both safe and yield-bearing, whales and institutional treasuries begin allocating at scale, treating P as a core reserve asset.

6.           Scale Emerges: Whale capital dramatically expands protocol TVL. Higher TVL generates more fees, which flow back into S-Token yields—further amplifying incentives for degens to participate.

In AquaFlux, the degen chasing memecoins and points is, in effect, underwriting the whale seeking stability. S-Token holders provide insurance for P-Token holders — and are paid handsomely for doing so.

This alignment of opposing intents—speculation and preservation, risk-seeking and risk-avoidance—is the true magic of Web3 financial engineering.

Chapter VI: Conclusion: Structured Finance as the New Language of On-Chain Capital

The emergence of AquaFlux marks a transition in the RWA space—from nouns to verbs. The industry no longer focuses solely on what an asset is; it begins to focus on how an asset is handled. The question shifts from “What is this asset?” to “How is this asset structured?”

As a financial engineering language for RWAs, AquaFlux is defining a new standard for bringing real-world assets on-chain. Through the Tri-Token vocabulary, complex, non-standard, and legally dense instruments are decomposed into simple, legible P, C, and S building blocks. What once required weeks of modeling by Wall Street structurers becomes a matter of seconds in smart contract execution. Risk and return are no longer negotiated in boardrooms — they are composed on-chain.

This combination of composability, structuring, and native risk pricing provides a powerful foundation for the convergence of DeFi and traditional finance. As more protocols adopt this paradigm, P/C/S can evolve into a universal language for RWAs—just as ERC-20 became the universal standard for fungible tokens.

As industry observers have noted, “When RWAs cease to be merely assets placed on-chain and instead become the foundational primitives of on-chain finance, a new DeFi cycle may begin.” The structured innovations pioneered by AquaFlux do more than address today’s liquidity and risk-management constraints. They establish a new paradigm. When structured finance becomes the everyday grammar of on-chain markets, the boundary between traditional finance and crypto will further dissolve — and an unprecedented financial ecosystem can emerge.

Executive Summary: From “Moving Assets On-Chain” to “Asset Restructuring”

Looking back at the history of DeFi, every major liquidity breakthrough has come from successfully abstracting and standardizing asset properties. ERC-20 abstracted value transfer, creating a universal standard for tokens and payments. AMMs abstracted the human role of market makers, enabling trading to be executed entirely by code.

3.2 Compositional Strategies

In this language, strategies become sentences, and P/C/S are the vocabulary.
What changes is not the asset itself, but the financial meaning it expresses.

This is the true value of Financial Legos: not the invention of new assets, but the ability for a single asset to express multiple, tradable, hedgeable, and composable financial meanings.

Chapter IV: The Evolution of Splitting: Beyond Pendle’s Time-Based Model

Across the history of DeFi, asset splitting has emerged as an increasingly explicit design pattern. What we observe is a clear evolutionary path—from simple abstractions to progressively richer structures. AquaFlux does not appear in isolation. It stands on the shoulders of earlier pioneers, completing the final missing piece in the splitting paradigm.

4.1 Pendle: Splitting Time and Yield

Pendle Finance is the pioneer of asset splitting in DeFi, achieving remarkable success with yield-bearing assets—particularly liquid staking derivatives such as stETH.

•             Splitting Model: Asset = PT (Principal) + YT (Yield)

In the context of stETH, this assumption largely holds. In RWAs, however, it breaks down. Corporate bonds carry inherent credit risk. If the Pendle model is applied directly to such assets, a default at the underlying level would transmit losses straight to PT holders. This constraint prevents Pendle from scaling natively into non-standard, credit-bearing RWA markets.

4.2 Polymarket: Splitting Probability and Outcome

Polymarket demonstrates a different extreme of asset splitting within the domain of prediction markets.

•             Splitting Model: Collateral (1) = YES Token + NO Token

•             Core Logic: This is an equation of probability. At all times, YES + NO = 1$.

•             Insight: Polymarket proves that by splitting a binary outcome, markets can price the probability of an event with remarkable precision. This price is not dictated by experts or models — it is discovered through real capital at risk. Probability becomes an asset, and belief becomes liquidity.

4.3 AquaFlux: Splitting Credit and Structure

AquaFlux synthesizes the strengths of both paradigms and elevates them to meet the specific demands of RWAs.

•             Splitting Model: RWA = P (Principal) + C (Coupon) + S (Credit Risk)

•             A New RWA Paradigm:

•             It inherits Pendle’s P/C logic, separating principal from yield and enabling interest-rate trading.

Before AquaFlux, distrusting an RWA meant only one option—not buying it. After AquaFlux, distrust becomes an expressible position. One can short S-Token or hold only P-Token to isolate and neutralize credit exposure. This represents the terminal form of asset splitting.

Chapter V: The Liquidity Engine: Harmonizing Speculation and Preservation

The fundamental reason traditional RWA tokens suffer from poor liquidity is simple: they are boring. They merely mirror an off-chain bond on-chain, forcing every participant to accept the same fixed yield—say, 5%—and the same undifferentiated risk. It is equivalent to asking everyone, from whales to retail users, to buy the exact same wealth product. The result is predictable: no one is truly satisfied, and no one trades.

AquaFlux inverts this logic. Instead of presenting RWAs as static instruments, it decomposes a single “boring” asset into three forms of DeFi-native gameplay that on-chain users already understand. Once an asset becomes a set of highly expressive LEGO blocks — modules that can be played with, combined, and strategized around—liquidity emerges naturally.

5.1 Three Tokens, Three DeFi Archetypes

AquaFlux is not selling bonds. It is offering three distinct tools for three archetypal on-chain users — each aligned with a different intent.

1. P-Token: On-Chain “Cash Management” / Prime Collateral

•             Target Users: Whales, DAO treasuries, stablecoin holders.

•             User Mindset:“I hold a large amount of stablecoins. I want slightly better returns than Aave deposits, but I absolutely cannot lose principal. I also don’t want to monitor markets every day.”

2. C-Token: A Long Position on Rates / Pure Yield Exposure

•             Target Users: Traders, hedge funds.

•             User Mindset:“I don’t want to lock up large amounts of capital to buy a bond. I just want to trade where rates are going.”

•             DeFi-Native Use Cases:

￮              Maximum Capital Efficiency: Buying C-Token is equivalent to taking a highly leveraged position on yield. Instead of spending 100 to earn 5 in interest, one can spend a fraction of that to acquire the right to those 5 units of yield.

￮              Trading the Fed: If a participant expects rates to rise, buying C-Token becomes a direct expression of that view. As rate expectations increase, the price of C can surge. In effect, C-Token functions as an on-chain interest-rate prediction market.

3. S-Token: A Leveraged “Mining Pickaxe” / Risk Capture Layer

•             Target Users: Yield farmers, degens.

•             User Mindset:“I’m fine with high risk — as long as the APY is high enough, or there are points and airdrops to farm, I’m in.”

•             DeFi-Native Use Cases:

￮              High-APY Farming: Because S-Token bears default risk, the system routes the majority of excess returns to it. This includes: A share of the underlying asset’s yield premium, protocol fee revenue, governance token incentives.

￮              Betting on Non-Default: Holding S-Token is, in essence, a wager that the underlying asset will not fail. As long as no default occurs, S-Token holders become the highest-yielding participants in the entire structure.

5.2 The Flywheel: Letting Speculators Protect Savers

AquaFlux’s most elegant design lies in its ability to harness Web3’s speculative instinct to construct systemic security. Speculation is not treated as a problem — it is transformed into infrastructure. This creates a self-reinforcing flywheel:

1.           Initiation: An issuer brings an RWA on-chain and splits it into P, C, and S.

2.           Speculative Entry (Degens Arrive): The market observes that S-Token offers high farming yields—driven by fees and token incentives. Yield farmers enter en masse, minting and holding S-Token.

3.           Shield Thickens: As the S-Token pool grows, so does the amount of capital available to absorb losses. The protective layer becomes deeper.

4.           Principal Becomes Safer: With a thick S layer beneath it, P-Token becomes increasingly resilient—structurally insulated from default risk.

5.           Whales Enter: Observing that P-Token is both safe and yield-bearing, whales and institutional treasuries begin allocating at scale, treating P as a core reserve asset.

6.           Scale Emerges: Whale capital dramatically expands protocol TVL. Higher TVL generates more fees, which flow back into S-Token yields—further amplifying incentives for degens to participate.

In AquaFlux, the degen chasing memecoins and points is, in effect, underwriting the whale seeking stability. S-Token holders provide insurance for P-Token holders — and are paid handsomely for doing so.

This alignment of opposing intents—speculation and preservation, risk-seeking and risk-avoidance—is the true magic of Web3 financial engineering.

Chapter VI: Conclusion: Structured Finance as the New Language of On-Chain Capital

The emergence of AquaFlux marks a transition in the RWA space—from nouns to verbs. The industry no longer focuses solely on what an asset is; it begins to focus on how an asset is handled. The question shifts from “What is this asset?” to “How is this asset structured?”

As a financial engineering language for RWAs, AquaFlux is defining a new standard for bringing real-world assets on-chain. Through the Tri-Token vocabulary, complex, non-standard, and legally dense instruments are decomposed into simple, legible P, C, and S building blocks. What once required weeks of modeling by Wall Street structurers becomes a matter of seconds in smart contract execution. Risk and return are no longer negotiated in boardrooms — they are composed on-chain.

This combination of composability, structuring, and native risk pricing provides a powerful foundation for the convergence of DeFi and traditional finance. As more protocols adopt this paradigm, P/C/S can evolve into a universal language for RWAs—just as ERC-20 became the universal standard for fungible tokens.

As industry observers have noted, “When RWAs cease to be merely assets placed on-chain and instead become the foundational primitives of on-chain finance, a new DeFi cycle may begin.” The structured innovations pioneered by AquaFlux do more than address today’s liquidity and risk-management constraints. They establish a new paradigm. When structured finance becomes the everyday grammar of on-chain markets, the boundary between traditional finance and crypto will further dissolve — and an unprecedented financial ecosystem can emerge.
