Evidencepartial
Transfer-based anti-money laundering (AML) systems monitor token flows through transaction-graph abstractions, implicitly assuming that economically meaningful value migration is sufficiently encoded in transfer-layer connectivity.
Implicationpartial
This is a foundational assumption explicitly stated in the abstract and introduction as the basis for current AML systems.
Verificationpartial
partial
Evidencepartial
In this paper, we demonstrate that this assumption—the bedrock of current industrial forensics—fundamentally collapses in composable smart-contract ecosystems.
Implicationpartial
This is the central thesis of the paper, explicitly stated in the abstract and elaborated throughout.
Verificationpartial
partial
Evidencepartial
First, we introduce Principal-Execution-Beneficiary (PEB) separation, where intent originators, transaction executors (e.g., MEV searchers), and ultimate beneficiaries are functionally decoupled.
Implicationpartial
The paper formalizes PEB separation as a key mechanism and explains its impact on attribution.
Verificationpartial
partial
Evidencepartial
Second, we formalize state-mediated value migration, where economic coupling is enforced through invariant-driven contract state transitions (e.g., AMM reserve rebalancing) rather than explicit transfer continuity.
Implicationpartial
The paper formalizes state-mediated value migration as another key mechanism that bypasses traditional transfer analysis.
Verificationpartial
partial
Evidencepartial
Through a real-world case study of role-separated limit order execution and a constructive cross-pool arbitrage model, we prove that these mechanisms render transfer-layer observation neither attribution-complete nor causally closed.
Implicationpartial
The paper explicitly states the consequence of these mechanisms on the completeness and causal closure of transfer-layer observation.
Verificationpartial
partial
Evidencepartial
We further argue that simply expanding transfer-layer tracing capabilities fails to resolve the underlying attribution ambiguity inherent in structurally decoupled execution.
Implicationpartial
The paper argues that simply enhancing existing transfer tracing is insufficient due to the structural issues.
Verificationpartial
partial
Evidencepartial
Under modular composition and open participation markets, these mechanisms are structurally generative, implying that heuristic-based flow tracing has reached a formal observational boundary.
Implicationpartial
The paper posits that these mechanisms are inherent and generative in current DeFi architectures, leading to a limit in traditional tracing methods.
Verificationpartial
partial
Evidencepartial
We advocate for a paradigm shift toward AML based on execution semantics, focusing on the restitution of economic causality from atomic execution logic and state invariants rather than static graph connectivity.
Implicationpartial
The paper concludes by proposing a new direction for AML, moving away from transfer-layer analysis.
